and Measurement of Elaboration on Potential
Outcomes

We examine a new construct dealing with individuals’ tendency to elaborate on
potential outcomes, that is, to generate and evaluate potential positive and negative
consequences of their behaviors. We develop the elaboration on potential outcomes (EPO) scale and then investigate its relationships with conceptually related
traits and its association with consumer behaviors such as exercise of self-control,
procrastination, compulsive buying, credit card debt, retirement investing, and
healthy lifestyle. Finally, we show that consumers with high EPO levels exhibit
more effective self-regulation when faced with a choice and that EPO can be
primed, temporarily improving self-regulation for consumers with low EPO levels.
S
on the potential outcomes of a decision or action—that lies at
the heart of self-regulation. We show that consumers differ
in their tendencies to engage in predecision outcome elaboration and that those who consider potential outcomes
when deciding how to behave exhibit more effective selfregulation endeavors. We argue that elaboration on potential
outcomes (EPO) represents a generalized predisposition toward thinking about consequences, encompassing four conceptually distinct dimensions. Specifically, it captures the
degree to which individuals (1) generate potential consequences of their behaviors, (2) evaluate the likelihood and
importance of these consequences, (3) encode anticipated
end states with a positive focus, and (4) encode them with
a negative focus.
Research by Mischel and colleagues has demonstrated
compelling differences among individuals in their self-regulatory strategies and cognitive competencies for exerting
self-regulation. This work has attempted to explain these
differences in terms of the mediating processes that underlie
them, such as individuals’ encoding strategies, expectancies,
values and goals, affective reactions, and self-regulatory
strategies (e.g., Mischel, Cantor, and Feldman 1996). They
propose that a challenging goal for future research is to more
fully understand how these mediating person-specific variables interact and guide the individual’s behavior “in the
long and often difficult road from willing to wishing to
willpower” (Mischel et al. 1996, 351). The construct examined here—EPO—is an essential component of self-regulation because it provides important feedback about the
elf-regulation failure creates numerous problems for
consumers unable to manage their money and time,
control their weight, or limit their drinking. The importance
of studying self-regulation is widely recognized since being
unable to regulate one’s emotions, impulses, actions, and
thoughts creates problems not only for individual consumers
but also for society as a whole (Baumeister, Heatherton, and
Tice 1994). Researchers have examined various conceptualizations of self-regulation, as well as factors that might
increase or impair its effectiveness. Some researchers have
proposed that exerting self-control requires one to inhibit
automatic reactions and to invoke conscious monitoring of
one’s actions (Baumeister and Heatherton 1996). Others
have suggested that self-control requires one to make decisions and to act in accordance with long-term rather than
short-term outcomes (Thaler 1991).
We examine one important predecision process—elaborating

ELABORATION ON POTENTIAL OUTCOMES
potential of a behavior to move people closer to or further
away from their goals (Carver and Scheier 1998).
The remainder of this article unfolds as follows. We first
review the theory of self-regulation and establish its relationship to consumers’ EPO. We then briefly discuss related
theories and constructs that deal with expectations about the
future and present our conceptual model. Next, we present
our scale development program, which contains analyses
aimed at developing a valid and reliable EPO scale, and
then use the scale to establish a link between EPO and
consumers’ self-regulation behaviors in our experimental
study. We conclude with a general discussion and suggestions for future research. This article is not simply about
developing a new scale. The substantive findings of the
structure of EPO and its relationship to consumer traits and
self-regulation behaviors are equally important.
We believe that understanding and measuring EPO is important for several reasons. First, EPO has important implications for consumer self-control effectiveness. As noted
by Baumeister (2002), the factors and processes that undermine self-control are worth studying since in the long
run, failing to exercise self-control and resist temptations
may lead to higher profits for companies but more unsatisfied and unhappy consumers. A second important reason is
the marketing field’s interest in measurement issues and in
developing high-quality instruments (e.g., Bearden and Netemeyer 1999). The Journal of Consumer Research has a
rich history of generating and using individual difference
scales (e.g., materialism [Richins and Dawson 1992] and
consumer self-confidence [Bearden, Hardesty, and Rose
2001]), which has enabled researchers to examine these
traits as moderators and identify boundary conditions to
important aspects of consumer behavior. Third, we show
that our EPO scale is very useful in predicting and explaining consumers’ information processes and choices.
ELABORATION ON POTENTIAL
OUTCOMES AND SELF-REGULATION
Self-regulation refers to the process by which people initiate, adjust, or terminate actions to promote attainment of
personal goals, plans, or standards (Carver and Scheier
1998). The process of self-regulation involves three important components: (1) having clear standards of how things
should be, (2) comparing one’s actual state to a desired state
(as defined by the standards), and (3) overriding responses
to bring about change when the current state falls short of
the desired state (Carver and Scheier 1998). Self-regulation
is a complex, multifaceted process, and issues related to
self-regulation have been examined in multiple domains
such as personality (Mischel et al. 1996), motivation (Bandura 1997; Gollwitzer 1990), social and cognitive psychology (Baumeister et al. 1994), and consumer research (Hoch
and Loewenstein 1991).
One important issue needing further examination is the
process of anticipation of potential desired and undesired
outcomes (e.g., Carver and Scheier 1998; Hoch and Loew-
127
enstein 1991). Elaboration on the potential outcomes of behavior not only makes people conscious of their standards
but also provides them with information as to whether an
act has the potential to move them toward a desired end
state or away from an undesired one. Thus, considering
future outcomes makes people more conscious of the possible effects of their behaviors and of the standards against
which to compare those outcomes. Such information leads
to better self-regulation and more appropriate behavior modification.
Baumeister and Heatherton (1996) argue that effective
self-regulation requires the individual to be able to transcend
the immediate situation by considering long-term consequences and implications. When transcendence is weak and
attention is bound to the here and now, the threat of selfregulation failure is greater. According to Baumeister and
his colleagues, “The factors that contribute to the success
or failure of transcendence deserve further study” (Baumeister et al. 1994, 259). They argue that factors directing
attention to future goals and implications will tend to improve the capacity for self-regulation (Baumeister and
Heatherton 1996). These may include both situational and
dispositional factors. We focus here on one such dispositional characteristic: one’s tendency to elaborate on potential
outcomes.
The idea that people’s actions are greatly affected by
potential outcomes is central not only to self-regulation theory—it has a long history in psychological theories of motivation as well (e.g., Rotter 1954). According to these theories, people motivate themselves and guide their actions
by the outcomes they expect to result from given courses
of behavior (Bandura 1997). Outcome consideration has been
conceptualized and examined as several different types of
expectancy judgments: self-efficacy expectations (whether
one can perform a certain behavior and is capable of achieving a particular outcome; Bandura 1997), outcome expectancies (the likelihood that performing a certain behavior
will lead to the desired outcome; Bandura 1997; Carver and
Scheier 1998), or general expectations (whether the future
in general will be positive or negative; Scheier, Carver, and
Bridges 1994). In contrast, our proposed construct adopts a
multidimensional perspective and represents a generalized,
context-independent predisposition toward thinking about
potential outcomes. It goes beyond expectancy judgments,
which only deal with assessing one’s capability (i.e., selfefficacy) or likelihood of achieving an outcome (i.e., outcome expectancy), and encompasses all aspects of the process of outcome consideration.
DIMENSIONALITY OF ELABORATION ON
POTENTIAL OUTCOMES
We argue that EPO conceptually encompasses four dimensions dealing with different aspects of the outcome consideration process: (1) generation of potential consequences,
(2) evaluation of the importance and likelihood of the generated consequences, (3) encoding consequences with a pos-

128
itive focus, and (4) encoding consequences with a negative
focus.
Generation Dimension
Mischel et al. (1996) point out that self-regulation and
goal pursuit are hard to execute, and individuals who can
only see a situation one way or imagine one worthy outcome
tend to do poorly. Thorough consideration of the effects of
an intended behavior helps people to regulate their behavior
in pursuit of a desired goal or to avoid an undesired one,
which is essential for self-regulation. Thus, the degree to
which people generate potential consequences before making decisions is an important element of the process of EPO.
Evaluation Dimension
The second proposed dimension, evaluation, is related to
outcome expectancies and concerns the extent to which people evaluate both the likelihood and significance of potential
consequences once they have generated them. Self-regulation theory suggests that outcome expectancies—people’s
subjective probability determinations that outcomes will or
will not occur—influence their decision to pursue a goal
versus to disengage (Carver and Scheier 1998). Thus, an
important component of the process of EPO is people’s
combined evaluations of the likelihood and importance of
the consequences they have generated.
Relative Positive/Negative Outcome Focus
Dimensions
Researchers have emphasized that it is insufficient to
know whether and when people regulate their behaviors; it
is also necessary to understand how people deal with their
world to make this happen (Higgins 1999). Prominent theories of self-regulation such as Carver and Scheier’s control
theory (1981) and Higgins’s self-systems theory (1999) emphasize the importance of examining people’s different approaches to self-regulation and of studying the effects of
adopting a positive (vs. negative) outcome focus in one’s
goal pursuit. Carver and Scheier (1981) make a distinction
between two types of self-regulatory systems, one having
a positive and one having a negative reference value. A selfregulatory system with a positive reference value involves
attempts to move closer to a desired end state, while a selfregulatory system with a negative reference value involves
attempts to move away from an undesired end state. Similarly, the principle of regulatory reference focuses on the
point of reference a person uses in self-regulation and argues
that, holding outcome expectations constant, self-regulation
can operate in reference to either a desired or an undesired
end state (Higgins 1999).
In our conceptualization of the process of outcome elaboration, we distinguish between people’s tendency to encode
anticipated end states with a positive versus negative outcome focus. Thus, we propose two further dimensions of
EPO: positive outcome focus and negative outcome focus.
JOURNAL OF CONSUMER RESEARCH
Aspects of Self-Regulation
Since the four proposed EPO dimensions converge on a
single underlying quality (latent variable) and each dimension reflects this latent variable imperfectly, EPO can be
considered a multifaceted construct (Carver 1989). EPO’s
subdimensions represent different aspects of the process of
outcome elaboration and consumers’ self-regulation processes. While the generation and evaluation dimensions relate to the depth of consumers’ self-regulation, the positive
and negative outcome focus dimensions relate to the overall
valence of consumers’ self-regulation.
According to the principle of regulatory anticipation, motivation arises from people’s anticipations of the outcomes
of their actions (Pham and Higgins 2005). Therefore, people
who tend to anticipate potential consequences will be more
motivated and thus more likely to succeed in their selfregulation efforts. According to the principle of regulatory
reference discussed earlier, people use different points of
reference in the process of self-regulation, and they can
regulate their behaviors by referring to either a positive or
a negative end state (Pham and Higgins 2005). For example,
two people might represent the same goal in terms of approaching a desired end state (e.g., being slim) versus avoiding an undesired end state (e.g., being fat), differing neither
in their motivation to achieve the goal nor in their expectations but only in their approach for achieving that goal.
Thus, we expect that relative outcome focus will trigger
different self-regulatory valence rather than affecting the
depth of self-regulation.
Even though outcome focus tendencies are not two ends
of a single continuum, and someone who focuses on positive
potential outcomes does not necessarily ignore negative ones
and vice versa, many people tend to exhibit a relative preference for encoding potential outcomes with either a positive
or a negative focus. Therefore, while we propose (and subsequently measure) distinct positive and negative outcome
focus dimensions, throughout the empirical part of our article we combine the two dimensions to create a relative
valence construct that can then be used to predict people’s
inclinations to use different self-regulation strategies.
We now turn to the task of developing and validating our
proposed EPO scale, following recommended scale development procedures (e.g., Netemeyer, Bearden, and Sharma
2003). We first test the scale’s reliability and dimensionality
and refine it using confirmatory factor analysis. We then
assess the discriminant and nomological validity of the scale
by relating it to a number of established psychological constructs, checking for potential social desirability bias, and
examining its effect on information processing in a specific
decision situation. Next, we assess test-retest reliability and
establish a link between the generation and evaluation dimensions of EPO and depth of self-regulation by relating
them to several self-regulatory behaviors.

sionality, discriminant validity, and predictive validity (e.g.,
see Bearden et al. 2001). To generate items for the EPO
scale, we first reviewed relevant literature and closely examined instruments used to measure similar constructs. Second, we conducted in-depth discussions with behavioral experts to generate an initial pool of 76 items. Four judges
were then given the definitions of the four dimensions and
asked to allocate the 76 items to one of the four dimensions
or to indicate that they did not belong to any. Third, after
eliminating items not consistently categorized by at least
three judges, we pretested the remaining items on a sample
of 260 University of Pittsburgh undergraduate students to
identify items that reduced the internal consistency of the
scale or that failed to load adequately in an exploratory
factor analysis. These items were dropped, and new domainrelevant items were added, resulting in 22 items for further
consideration (generation dimension—six items; evaluation
dimension—five items; positive focus dimension—four
items; negative focus dimension—seven items).
Scale Reliability and Factor Structure (Sample 1)
We collected data from 367 University of Pittsburgh undergraduate students (51% female), who received extra
course credit for participating in the study. Participants were
given survey packages containing measures representing the
proposed EPO scale, eight established scales described below, and a measure of socially desirable responding (Paulhus
1991). For all of the scales administered, participants were
asked to indicate their agreement using seven-point Likert
scales ranging from one (strongly disagree) to seven (strongly
agree).
In order to assess the EPO scale’s dimensionality, the 22
items were subjected to confirmatory factor analysis. Since
the four dimensions of the scale are assumed to be conceptually and empirically related to each other, a four-factor
correlated model was estimated. Nine items that did not have

sufficiently high loadings on their underlying factors were
dropped, and the four-factor model was then reestimated.
Upon further investigation, we found that there was insufficient discrimination (see Fornell and Larcker 1981) between the generation and evaluation dimensions, with the
squared phi correlation between these two factors (0.84)
greater than the average variance extracted for generation
(0.57) and evaluation (0.60). Thus, we estimated a new
three-factor correlated model, with the generation and evaluation items combined into a single dimension. The resulting
item loadings are reported in table 1.
The three-factor and four-factor correlated models provide
similar fits to the data, so in the interest of parsimony, we
employ a three-factor correlated model and combine the
generation and evaluation items for all subsequent analysis
and discussion. (For all of our analyses, we estimated both
separate scores for generation and evaluation and a combined score and consistently found very similar results.) All
goodness-of-fit statistics for the three-factor correlated model
meet or exceed recommended levels (e.g., Bollen 1989; root
mean square error of approximation [RMSEA] p .07; goodness-of-fit index [GFI] p .94; adjusted goodness of fit index
[AGFI] p .90; comparative fit index [CFI] p .96; incremental fit index [IFI] p .96; relative fit index [RFI] p .92).
Means, standard deviations, and coefficient alphas for the
final 13-item scale, as well as correlations between the EPO
dimensions, are presented for all our samples in table 2.
Cronbach’s alpha estimates for the three subscales provide
evidence for good internal consistency (Nunnally 1978).
Confirmatory Factor Analysis (Sample 2)
After reducing the scale to 13 items (table 1), the EPO
instrument was administered to a different, newly collected
sample of 383 respondents, both students (n p 145, 47%
female) and adults (n p 238, 43% female). Participants in
the student sample were undergraduate marketing students

at the University of Pittsburgh, while participants in the adult
sample were adults enrolled in an executive education evening MBA program (n p 138) and university staff members
(n p 100). The adult and student samples were analyzed
separately, but results were virtually identical across the
two groups, so the two samples are combined for all subsequent analyses. Analysis of the new sample confirms that a
three-factor correlated model provides a good fit to the data
(RMSEA p .06; GFI p .94; AGFI p .91; CFI p .96;
IFI p .96; RFI p .93). Also, all scale items have factor
loadings above .74, providing strong evidence for scale reliability.
Scale Validity (Sample 1)
Nomological and Discriminant Validity. In order to
assess the discriminant and nomological validity of the
EPO scale, we examined whether it is distinct from other
related constructs. As discussed earlier, the generation and
evaluation dimensions are related to consumers’ depth of
processing and affect their depth of self-regulation, so we
explore their relationship to other constructs that have previously been used to examine depth of processing and depth
of self-regulation: impulsive buying (Rook and Fisher 1995),
compulsive buying (Faber and O’Guinn 1992), need for
cognition (Cacioppo and Petty 1982), consideration of future
consequences (Strathman et al. 1994), and risk aversion
(Donthu and Gilliland 1996). Since the positive and negative outcome focus dimensions are related to people’s
approaches to self-regulation and relate to their use of different reference values in self-regulation (i.e., overall valence), we relate them to a different set of constructs that
have been used to examine regulatory orientations: optimism
(Scheier et al. 1994), chronic regulatory focus (Higgins et
al. 2001), and defensive pessimism (Norem and Cantor
1986). Because of time constraints and the significant length
of the questionnaire, not all participants received all scales
included in the study. Everyone completed the EPO, impulsiveness, risk aversion, need for cognition, consideration
of future consequences, and compulsive buying scales, while
only a subset of participants received the optimism (n p
163), defensive pessimism (n p 163 ), and regulatory focus
(n p 135) scales.
Although we are able to empirically distinguish among
three dimensions of EPO, our subsequent analyses combine
the positive and negative focus measures to form a relative
outcome focus subscale score. Specifically, this score is
formed by dividing the difference between the positive and
negative outcome focus scores by their sum. We do this to
simplify the exposition, and we thank a reviewer for this
suggestion. Table 3 describes each construct measured in
sample 1 and its predicted (and actual) relationship with the
ELABORATION ON POTENTIAL OUTCOMES
appropriate EPO subscale with which it is expected to correlate—the generation/evaluation or the relative outcome focus subscale.
Table 3 also reports each construct’s correlations with the
EPO subscale it is not expected to correlate with. We conducted dependent correlation tests using the Hotelling-William test (Steiger 1980) to examine differences in the correlations of the measured constructs with the generation/
evaluation and the relative outcome focus subscales. Results
reveal that there are significant differences in the relative
strength of each construct’s correlation with the two EPO
subscales. That is, each construct’s correlation with the EPO
subscale it was expected to correlate with was significantly
stronger than its correlation with the other EPO subscale.
These results support our contention that generation/evaluation and relative outcome focus correlate with different
sets of constructs. Furthermore, all of the predicted correlations are significant and in the expected direction. Since
we find that all correlations are significantly different from
unity, we conclude that the EPO scale is nomologically
linked to related constructs yet possesses strong discriminant
validity.
As discussed earlier, we explore five constructs that assess
individuals’ depth of processing and depth of self-regulation
(impulsive buying, risk aversion, need for cognition, consideration of future consequences, and compulsive buying).
We predict that they will be significantly related to the generation/evaluation subscale of EPO. The exception is risk
aversion, to which the relative outcome focus subscale
should also be significantly related. The generation/evaluation subscale is related to each construct in the expected
fashion: impulsive buying (r p ⫺0.33, p ! .01), risk aversion (r p 0.30, p ! .01), need for cognition (r p 0.13,
p ! .01), consideration of future consequences (r p 0.43,
p ! .01), and compulsive buying (r p ⫺0.25, p ! .01). Risk
aversion is negatively correlated with the relative positive
outcome focus subscale (r p ⫺0.23, p ! .01).
We expect the four constructs that assess individuals’ regulatory orientations and self-regulation valence (optimism,
promotion regulatory focus, prevention regulatory focus,
and defensive pessimism) to be significantly related to the
relative outcome focus subscale of EPO but unrelated to the
generation/evaluation subscale. As shown in table 3, the
nature of the relationship between the relative positive focus
subscale is consistent with our expectations: optimism
(r p 0.61, p ! .01), promotion regulatory focus (r p 0.25,
p ! .01), prevention regulatory focus (r p ⫺0.20, p ! .01),
and defensive pessimism (r p ⫺0.51, p ! .01).
Further evidence of discriminant validity is provided by
following three steps recommended by Netemeyer et al.
(2003). First, we examined whether the variance-extracted
estimates for each pair of constructs exceeded the squared
phi estimate between the constructs (Fornell and Larcker
1981). This was the case for all 24 comparisons, indicating
discrimination between the EPO dimensions and each respective scale. Second, we conducted a series of chi-square
difference tests, comparing each of the measured constructs
131
to each dimension of the EPO scale (Anderson and Gerbing
1988). For each pair of constructs, we tested whether a twofactor model with unconstrained intercorrelation between
the constructs fits significantly better than a one-factor model
(correlation constrained to one). The two-factor model fit
significantly better than the one-factor model in all cases
(all p’s ! .001). Finally, we confirmed that the correlation
between each pair of variables, plus or minus two standard
errors, did not include the value of one.
Tests for Social Desirability Biases. The next important step in our scale development program was to assess
the extent to which responses to the EPO scale might be
confounded by social desirability response bias (Mick 1996).
Such an examination seemed warranted as there has been
some emphasis in the popular press on the importance of
outcome consideration for consumers’ self-control efforts
(e.g., Chatzky 2006). Since considering the consequences
of one’s behavior might be viewed as a socially desirable
trait, we assessed the extent to which the EPO subscales
are correlated with a measure of desirable responding proposed by Paulhus (1991)—impression management (IM).
EPO’s subscales have relatively weak correlations with IM
(rg/ev p 0.16, p ! .05; rrof p ⫺0.02, NS), which suggests
that responses on these subscales are not strongly influenced
by IM motives.
Paulhus (1991) also developed the self-deceptive evaluation (SDE) scale. SDE is a positively biased view of oneself
that is unconscious and honestly held and manifests itself
in tendencies to avoid negative thoughts, have high expectancies of success, and high perceived decision control. Both
EPO subscales correlate positively with SDE (rg/ev p 0.21,
p ! .05; rrof p 0.36, p ! .01), but Zerbe and Paulhus (1987)
recommend against controlling for SDE. Since self-deception is characteristic of well-adjusted people, controlling for
it may partial out important content variance related to the
personality factor of interest (Mick 1996).
We also follow the procedure recommended by Mick
(1996) and compute partial correlations between EPO and
the constructs discussed previously, holding IM constant.
The comparative results between simple and partial correlations revealed very small absolute differences, indicating
no spurious correlations due to social desirability bias. Since
the correlation between the generation/evaluation subscale
and IM was significant, we went one step further and examined whether IM moderates the relationship between this
EPO subscale and one of its consequences—compulsive
buying. For this purpose we estimated a hierarchical regression model using IM, the two EPO subscales, and the
interactions between IM and the EPO subscales as independent variables to predict compulsive buying. Only the
generation/evaluation subscale emerged as a significant predictor of compulsive buying (b p ⫺.18, t p ⫺1.99, p !
.05).

construct’s temporal stability, EPO was administered to a

Related to depth of processing and
depth of self-regulation:
Rook and Fisher (1995) suggest that an impulse’s urge toward immeImpulsive buying (n p 367)
diate action discourages consideration of the behavior’s potential
outcomes and encourages people to act with little or no regard for
long-term consequences. Wishnie (1977) suggests that individuals
with impulsive pathologies seem to be living in a state of constant
but stable chaos with little perspective about the future consequences of their current behavior.
People who are more averse to taking risks should be more likely to
Risk aversion (n p 367)
carefully assess the potential consequences of their behavior before
undertaking something. Furthermore, research has found a positive
relationship between people’s risk aversion and their tendency to
attend to and weigh potentially negative outcomes more heavily
(Schneider and Lopes 1986).
Need for cognition is conceptualized as the relative proclivity to proNeed for cognition (n p 367)
cess information (Cacioppo and Petty 1982). Need for cognition and
EPO represent different types of information processing. Need for
cognition measures consumers’ tendency to engage in and enjoy
thinking in general, while EPO measures their tendency to engage
in a specific type of thinking. Persons scoring high on the need for
cognition scale and who intrinsically enjoy thinking should be more
likely to generate and evaluate potential outcomes, while individuals
who are low in need for cognition and tend to avoid effortful cognitive work should be less likely to elaborate on potential outcomes.
Consideration of future conseThis construct captures the degree to which people consider potential
quences (n p 367)
distant outcomes rather than immediate ones when they choose
their present behavior. Consideration of future consequences (CFC)
measures consumers’ temporal focus on the short- versus longterm implications of behavior, while EPO measures their tendency
to anticipate these implications in the first place. We expect that
there will be a positive relationship between these tendencies, as
Strathman et al. (1994) argue that high-CFC individuals should be
more likely to generate and consider possible future outcomes even
when future consequences are ambiguous.
Compulsive buying (n p 367)
While initially providing some perceived benefits, compulsive buying is
a chronic behavior that typically becomes very difficult to stop and
ultimately results in harmful consequences (Faber and O’Guinn
1992). Compulsive buying represents a major failure of self-regulation efforts; compulsive buyers who amass unmanageable amounts
of debt can create economic and emotional problems for themselves and their families, so we expect that they are less likely to
elaborate on potential outcomes.

general expectancies have distinctive effects on people’s motivation
and behavior and represent different constructs that explain unique
variance when examined together (Scheier, Carver, and Bridges
1994). Optimism/positive focus and pessimism/negative focus are
distinct yet correlated. Optimism/pessimism describes generalized

are related to each other.

This strategy functions defensively in that it prepares individuals for
the possibility of failure. Defensive pessimists tend to set significantly lower expectations for their performance than optimists. People using this strategy think about worst-case scenarios as they anticipate upcoming situations and enter those situations expecting
the worst (Norem and Cantor 1986). Therefore, we expect that defensive pessimism will be positively related to a tendency to encode
potential outcomes with a negative reference value.

new sample of 114 University of Pittsburgh undergraduate
students who received extra credit for their participation.
One month later, 97 of these students completed a second
administration. We used a 1-month gap between the two
assessments to allow enough time for memory effects to
fade. The between-administration correlations for both subscales were high (rg/ev p 0.77, p ! .001; rrof p 0.81, p !
.001), demonstrating strong test-retest reliability.
Predictive Validity (Sample 4)
To provide evidence of the predictive validity of the EPO
scale, we examine whether the two EPO subscales predict
the extent to which participants think about potential consequences in a decision-making situation. In particular, we
expect that participants’ scores on the generation/evaluation
subscale will predict the number of consequences they generate when making a decision and that their scores on the
relative positive outcome focus subscale will predict the
number of positive and negative consequences generated.
Method. One hundred and sixty undergraduate students
(60% female) participated in return for extra course credit.
Participants were presented with two scenarios, each describing a situation in which they had to make a decision.
One scenario described a decision of whether to have laserassisted in situ keratomileusis (LASIK) surgery (LASIK surgery scenario), while the other described a decision of
whether to charge an expensive electronics good on an already heavily charged credit card (credit card scenario). The
scenario presentation order was counterbalanced across participants.
After reading each scenario, participants were asked to
record the thoughts that went through their minds as they
considered what to do. After completing these tasks for both
scenarios, participants were asked to code the valences of
the thoughts they had previously listed by putting a plus
sign next to positively valenced thoughts and a minus sign
next to negatively valenced thoughts. After a distraction
task, which required participants to complete a 10-minute
survey containing questions unrelated to this study, they
were administered the EPO scale.
Two judges unaware of the study hypotheses coded each
thought as either a consequence (e.g., “I might go blind”)
or a nonconsequence (e.g., “What is the price of the surgery?”). We were only interested in the number of consequences generated by participants, so we classified all other
thoughts as nonconsequences. Interrater agreement was 90%
for the LASIK surgery scenario and 93% for the credit card
scenario, with disagreements resolved through discussion.
The kappa coefficient verifies that agreement between the
two raters exceeds that expected by chance (0.83, p !
.001, for the LASIK scenario, and 0.87, p ! .001, for the
credit card scenario).
Results and Discussion. We calculated scores for the
three EPO dimensions and counted the number of positive
(MLASIK p 0.85, SD p 0.93; Mcc p 0.48, SD p 0.70), neg-
ative (MLASIK p 1.73, SD p 1.02; Mcc p 1.24, SD p 0.89),
and total (MLASIK p 2.58, SD p 1.39; Mcc p 1.71, SD p
1.08) consequences that people generated in response to the
two scenarios. Participants generated a significantly greater
number of consequences in response to the LASIK surgery
scenario than in the credit card scenario (all p’s ! .01), perhaps because laser eye surgery has more dramatic long-term
or permanent consequences than a single credit charge. Furthermore, the LASIK surgery decision involves a variety of
potential risks and benefits in different domains (e.g., health,
appearance, personal finances), whereas the credit card situation involves mainly financial risks.
Since the numbers of positive, negative, and total consequences generated are count variables, we employed Poisson regression to analyze how the EPO dimensions affect
them. The three dimensions of the EPO scale were used as
independent variables in a set of six Poisson regressions on
the number of positive, negative, and total consequences
generated in response to the two scenarios. (In all of our
studies, we find that there are no significant gender effects,
and that multicollinearity—as judged by variance inflation
factor values—is not a concern.)
The results support our predictions (see table 4). The
generation/evaluation EPO subscale is a significant predictor
of the number of consequences generated in response to the
two decision situations (b LASIK p .19, x 2 p 11.80, p ! .01;
bcc p .16, x 2 p 5.20, p ! .05), and the relative positive outcome focus subscale is positively and significantly related to
the number of positive consequences generated (b LASIK p
1.23, x 2 p 10.06, p ! .01; bcc p 1.52, x 2 p 8.23, p ! .01)
and negatively and significantly related to the number of negative consequences generated (b LASIK p ⫺.68, x 2 p 6.43,
p ! .01; bcc p ⫺.98, x 2 p 9.65, p ! .01). Furthermore, participants’ scores on the generation/evaluation subscale are

ELABORATION ON POTENTIAL OUTCOMES
also significantly related to the combined number of positive
and negative consequences they generated. These results
provide further evidence of the validity of the subscales
since they confirm that people with a greater general tendency to generate consequences come up with more positive
and more negative consequences in a specific decision situation. It is worthwhile to note that both of the scenarios
we used include potential outcomes that are very negative,
and it is quite possible that more negative than positive
consequences came to mind for many consumers as they
made their decisions. While it will ultimately be useful to
examine EPO across a wider range of scenarios that vary
in terms of the extremity of both negative and positive outcomes, the fact that EPO is able here to predict the number
of both negative and positive outcomes considered—where
the scenarios may be biased in favor of negative outcomes—provides strong empirical support for our proposed
scale.
Next, we delve into the consequences of EPO. As discussed earlier, the generation/evaluation of potential outcomes is related to the depth of people’s self-regulation,
while outcome focus is related to their self-regulation valence. Therefore, in the following two studies we examine
these subscales separately and relate them to different sets
of consequences.
Consequences of Generation/Evaluation of
Potential Outcomes (Sample 5)
Earlier, we argued that EPO is an important determinant
of self-regulation. However, an important question arises:
does EPO incrementally explain self-regulatory behavior
above and beyond what is accounted for by other constructs?
We examine whether consumers’ tendency to think about
the implications of their behaviors can predict the extent to
which they engage in these behaviors. Consumers who generate and evaluate a variety of potential consequences when
deciding how to behave should be more likely to persist in
goal pursuit and exercise effective self-regulation (e.g., Baumeister and Heatherton 1996). Thus, we expect that the
generation/evaluation EPO subscale will be a positive predictor of a number of behaviors resulting from self-regulation effectiveness. However, the relative outcome focus
subscale, which is related to the overall self-regulation valence, is not expected to predict consumers’ engagement in
behaviors resulting from self-regulation effectiveness.
Procedure. To enhance the generalizability of our findings, we recruited 302 adults (57% female) ranging in age
from 20 to 70 years old. Questionnaires were distributed to
a quota-convenience sample of adult consumers by 63 University of Pittsburgh marketing students, who received extra
course credit for recruiting up to 10 adults who were not
full-time college students (e.g., Mick 1996). Participants first
received a survey that included measures of procrastination,
credit card abuse, alcohol abuse, healthy eating, and regular
exercising. After completing a distracter task, participants
were given a second, seemingly unrelated, questionnaire that
135
contained the EPO scale as well as measures of four conceptually related traits used to predict self-regulation behaviors in past research: buying impulsiveness, consideration of future consequences, risk aversion, and cognitive
self-control. The first three of these constructs were discussed earlier. Since self-regulation researchers have argued
that some people chronically have more problems with selfcontrol than others (e.g., Baumeister 2002), we also assessed
individual differences in self-control skills using the cognitive self-control scale (Rohde et al. 1990). As before, independent variables were measured on a seven-point Likert
scale.
The average score for the consideration of future consequences scale (Strathman et al. 1994) in our sample is 4.40
(SD p .70; a p 0.77). Our sample’s average risk aversion
score (Donthu and Gilliland 1996) is 4.52 (SD p 1.06;
a p 0.60), while the average impulsiveness score (Rook
and Fisher 1995) is 3.40 (SD p 1.25; a p 0.90). The average self-control score is 4.57 (SD p .75; a p 0.87). Correlations between the independent variables ranged from
0.66 between impulsiveness and compulsiveness to 0.02 between risk aversion and need for cognition.
We measured procrastination using the 15-item adult inventory of procrastination (Ferrari, Johnson, and McCown
1995; M p 3.24, SD p .95; a p 0.86). Alcohol abuse was
measured in terms of frequency of drinking by a validated
single-item measure (Newcombe, Measham, and Parker
1995; M p 4.0). Healthy diet was measured in terms of the
frequency of consumption of fruits and vegetables—two of
the major components of the healthy eating index developed
by the Center of Nutrition Policy and Promotion at the U.S.
Department of Agriculture (see Basiotis et al. 2004; M p
7.0). Exercise habits were assessed via frequency of physical
activity (Laaksonen et al. 2002; M p 7.0). Credit card abuse
was measured by asking those participants who had credit
cards (n p 258) to report how often they pay their credit
card balance in full. Their responses ranged from one (never,
I always carry a balance) to four (I pay my entire balance
every month; M p 2.0). All frequency-based dependent
variables were measured on a 10-point scale ranging from
one (never) to 10 (every day).
Results and Discussion. To assess whether EPO predicts self-regulation failure beyond the effects of other related traits, we employed a multivariate analysis of variance
with the two EPO subscales, self-control, impulsiveness,
consideration of future consequences, and risk aversion as
independent variables and measures of drinking, healthy eating, exercising, money management, and procrastination as
dependent variables. We employed a MANOVA in order to
take into account the relationships between the dependent
measures (correlations between the dependent measures
ranged from r p 0.06, NS, between alcohol abuse and regular exercise, and r p 0.35 , p ! .01, between healthy eating
and regular exercise). We found that all results are in the
predicted direction and, as can be seen in table 5, the tendency to generate and evaluate potential outcomes is a significant and substantial predictor for every dependent var-

iable. As predicted, relative positive outcome focus has no
effect on the dependent variables (with the exception of
procrastination to which it is negatively related).
Following the omnibus analysis, we conducted additional
analyses employing a series of stepwise regression models.
In each model, self-control, impulsiveness, consideration of
future consequences, and risk aversion were first entered as
independent variables that might explain a specific behavior.
EPO was then entered into the model in the second step.
As expected, the tendency to generate and evaluate potential
outcomes was a significant and substantial incremental predictor in all of these models, as evidenced by a statistically
significant improvement in R2 (see table 5) between step 1
and step 2 ( p ! .05) for all but one model (healthy eating).
Our findings show that consumers’ tendency to generate
and evaluate potential outcomes is a significant predictor of
the self-reported frequency of engaging in behaviors resulting from (in)sufficient self-regulation such as drinking,
exercising, money management, and procrastination, thus
further establishing the predictive validity of the EPO construct. These analyses provide evidence that the EPO construct and its measurement have the potential to increase
our understanding of the determinants of effective consumer
self-regulation.
PART 2: EXPERIMENTAL VALIDITY
OF EPO
Thus far, we have shown that the EPO scale is a reliable
and valid instrument and that the EPO construct is an important determinant of self-regulation. In this study, we provide evidence that consumers’ EPO scores affect their depth
of self-regulation and their preferences when faced with a
specific choice. Furthermore, we show experimentally that
EPO can be primed and that this priming can temporarily
improve self-regulation for consumers with lower levels of
EPO. Recent studies of consumers’ investments show that
consumers generally underinvest in savings (e.g., Morgen-
son 2003). Since investment decisions have major implications for investors’ future financial welfare, this tendency
is likely to create significant problems in the future for individuals and society. For instance, Laibson, Repetto, and
Tobacman (1998) find a positive relationship between failure
to invest and lack of self-control.
As we have already shown, the generation and evaluation
of potential consequences in the predecision stage is an important determinant of effective self-regulation since it helps
consumers transcend the immediate situation and consider
the future consequences of their behaviors. Since having
retirement savings is a desired and important goal, we expect
that outcome elaboration will prompt participants to regulate their behavior in a way that brings them closer to
this desired goal. Therefore, we expect that high EPO investors—compared to low EPO investors—will be more
likely to consider the implications of saving versus not saving for retirement, will be more likely to exercise self-regulation, and will therefore tend to invest more money for
their retirement.
Furthermore, we experimentally test whether predecision
EPO can increase self-regulation effectiveness, at least temporarily. If EPO does indeed lead to more effective selfregulation, then encouraging investors to transcend the immediate situation and consider potential future outcomes
should improve self-regulation efforts for those investors
not normally inclined to engage in this type of elaboration.
We predict that priming investors to consider the potential
outcomes of behavior will temporarily aid lower EPO investors and enhance their self-regulation effectiveness, leading to higher levels of investment.
A tendency to encode potential outcomes with a positive
outcome focus should increase sensitivity to gains and trigger greater eagerness to achieve gains, while a tendency to
encode potential outcomes with a negative focus should
increase sensitivity to losses and trigger a greater vigilance
to assure safety. Research has found that eagerness usually
translates to greater openness to risk, whereas vigilance is
ELABORATION ON POTENTIAL OUTCOMES
usually characterized by less openness to risk (Pham and
Higgins 2005). Furthermore, according to the regulatory
compatibility phenomenon discussed by Pham and Higgins
(2005), information compatible with one’s regulatory focus
receives more attention and is given more weight in judgment. Similarly, we expect that a tendency to encode outcomes with a positive versus negative focus will raise attention to information that is compatible with this view and
increase the weight that this information receives during
judgment. Options that are attractive on compatible dimensions will be evaluated more favorably. Therefore, when
offered different types of mutual funds, people with a relative positive outcome focus will invest more money in the
stock fund, which has an aggressive risk level and has the
greatest potential for gain. However, people with a relative
negative outcome focus will invest more money in the
money market fund, which has a conservative risk level and
has the smallest potential for loss. We do not expect significant differences in money allocations to the bond fund,
which has a conservative to moderate risk level and has
moderate potential for positive and negative outcomes.
Method
Participants in this study were 95 adults (55% female)
who were intercepted at Pittsburgh International Airport.
They were given a questionnaire describing a scenario in
which they had just begun working for a company that
offered them an opportunity to invest in a 401(k) retirement
plan. Study participants were given general information
about 401(k) plans and told that they had $15,000 in discretionary income that they could either spend as they
wished or invest some or all of it in the 401(k) plan. Respondents were shown descriptions of three mutual funds
they could choose from and were asked to indicate whether
they would invest in the 401(k) plan and, if so, how much
of the $15,000 they would invest. They were then asked to
allocate the money they chose to invest across the three
funds—a stock fund, a bond fund, and a money market fund.
Participants were given a description of the funds’ objectives, their risk level, the types of financial instruments they
invest in, and their average annual returns for 1, 5, and 10
years.
Respondents were randomly assigned to one of two experimental conditions. In one condition, they read the scenario and were immediately asked to indicate how much of
the money they would invest in the plan and to allocate the
money to the available mutual funds. In the other condition,
EPO was primed after participants read the scenario but
before they provided their responses. To prime outcome
elaboration, we used an adaptation of Gollwitzer’s deliberative mind-set priming procedure (e.g., Gollwitzer 1990),
asking people to consider the positive and negative outcomes
of investing or not investing in the 401(k) plan.
After participants decided how much and how to invest,
they were questioned about their real-life retirement investments. They were asked to indicate whether they have
a 401(k) type of plan and whether they have a traditional
137
pension plan. Next, we measured the EPO scale on a fivepoint Likert scale. Finally, we measured participants’ involvement with the goal of investing for retirement (four
seven-point semantic differential scale questions anchored
by unimportant/important, irrelevant/relevant, insignificant/
significant, and of no concern/of concern) and asked them
to report their gender, age, income, and employment status.
Results and Discussion
We first confirmed that investing for retirement is an important and desirable goal for consumers. Participants reported high perceived goal importance (M p 6.5, SD p
.84), relevance (M p 6.4, SD p 1.30), significance (M p
6.5, SD p 1.09), and concern with investing for retirement
(M p 6.5, SD p 1.07). None of these measures had significant correlations with the two EPO subscales.
To test our prediction regarding the effects of the generation/evaluation EPO subscale, we ran a regression on the
amount of money participants invested in the proposed
401(k) plan. We included the generation/evaluation EPO
subscale, the EPO priming manipulation (1 p priming;
⫺1 p no priming), and their interaction, as independent
variables, and the relative outcome focus EPO subscale,
issue involvement, gender, age, income, and employment
status, as controls. The analysis reveals that both EPOg/ev
(b p 1,927, t p 4.23, p ! .01) and the EPO priming manipulation (b p 5,206, t p 2.74, p ! .01) are significant
predictors of the amount of money invested. We also found
a significant two-way interaction between EPOg/ev and the
EPO priming condition (b p ⫺1,072, t p ⫺2.39, p ! .01).
Subsequent examination of group means reveals that in the
no-priming condition, investors with stronger outcome elaboration tendencies allocated nearly twice as much money to
the 401(k) plan as investors with weaker such tendencies
(Mhi g/ev p $11,008; Mlo g/ev p $6,500, t(94) p 4.26, p !
.01). However, priming equalized the amounts invested by
the two groups of investors by almost doubling low EPO
investors’ participation in the 401(k), while not affecting high
EPO investors’ participation (Mhi g/ev p $10,938; Mlo g/ev p
$10,368; t(94) p .81, NS; see fig. 1). As expected, participants’ relative outcome focus scores were not significantly
related to the amount of money they invested in the proposed
401(k) (b p 467.62, t p 0.35, NS). None of the control
variables had a significant effect.
To test our prediction regarding the effects of relative
outcome focus, we ran three regressions on the amount of
money participants allocated to each of the three mutual
funds they could choose from in the proposed 401(k) plan.
We included the relative outcome focus subscale, the EPO
priming manipulation, and their interaction, as independent
variables, and the generation/evaluation subscale, issue involvement, gender, age, income, and employment status, as
controls.
The analysis revealed that relative positive outcome focus
is a significant positive predictor of the amount invested in
the stock fund (b p 3,608, t p 2.91, p ! .01), a significant
negative predictor of the amount invested in the money

market fund (b p ⫺1,841, t p ⫺2.42, p ! .01), and a negative but not significant predictor of the amount invested in
the bond fund (b p ⫺1,911, t p ⫺1.65, NS). The EPO
priming manipulation was a significant positive predictor of
money allocated to the bond fund (b p 813.31, t p 2.26,
p ! .05), while its interaction with relative positive outcome
focus did not have a significant effect on any of the dependent variables. The only control variable that had a significant effect was gender, which was significantly related to
the amount allocated to the stock fund (b p ⫺1,527, t p
⫺2.06, p ! .05), with males allocating significantly more
than females (Mm p $5,154; Mf p $3,663, t(91) p 2.08,
p ! .05), and generation/evaluation, which was a significant
positive predictor of the amount of money allocated to the
stock fund (b p 1,337, t p 3.14, p ! .01). Based on a tertiary split we divided investors in two groups—with relative
positive and relative negative outcome focus. Subsequent
examination of group means revealed that investors with
stronger relative positive outcome focus allocated nearly
twice as much money to the stock mutual fund as investors
with a relative negative outcome focus (Mpof p $5,126;
Mnof p $3,027, t(46) p 2.85, p ! .01), while investors with
a relative negative outcome focus allocated more than
twice as much money to the money market mutual fund as
investors with a relative positive outcome focus (Mpof p
$1,029; Mnof p $2,281; t(46) p 2.46, p ! .05). As expected, there was no difference in allocations to the bond
mutual fund (Mpof p $3,388; Mnof p $3,796; t(46) p
0.27, NS; see fig. 2).
We also examined whether consumers’ tendency to generate and evaluate potential outcomes affects their real-life
choices by testing whether investors’ EPO tendencies predict
the likelihood that they have traditional pension plans and
401(k) type of plans. We do not expect EPO to be a significant predictor of whether participants have traditional
pension plans because these plans are not typically optional
and do not require employees to make investment decisions.
However, we expect that EPO will be a significant positive
predictor of the likelihood that participants have a 401(k)
type of plan, where participation is decided by employees
and requires them to contribute part of their income. After
deleting participants who were unemployed or employed
part time, we used the remaining 71 participants’ responses
to estimate two logistic regression models assessing whether
they have (1) a traditional pension plan and (2) a 401(k)
type of plan. As predicted, participants with a higher tendency to generate and evaluate potential outcomes, when
compared to other participants, are no more likely to have
traditional pension plans (b p .12, odds ratio p 1.14, NS)
but are significantly more likely to have a 401(k) type of
plan (b p .76, odds ratio p 2.14, p ! .05).
Results from this study provide strong support for the
validity of the EPO scale. Apart from showing that individual differences in outcome elaboration tendencies are important determinants of consumers’ self-regulation effectiveness and strategic orientations, this study goes one step
further and shows that consumers can be aided (at least
temporarily) in exercising better self-regulation by priming
them to consider potential outcomes before making a decision. We also provide evidence that consumers’ outcome
elaboration tendencies are related to their real-life investments by showing that investors with strong EPO tendencies
are significantly more likely to have an optional type of
retirement investment instrument such as a 401(k) plan.

GENERAL DISCUSSION
also show that considering the outcomes of behavior is negatively correlated with impulsiveness and compulsive buying. Since disregard for the consequences (e.g., potential
poverty) seems to be an important component of impulsive
buying, encouraging predecision outcome elaboration in a
shopping context might be able to help consumers resist
their impulses for excessive buying.
Our analyses also suggest that EPO may act as a moderator. Researchers should examine how EPO moderates
consumers’ responses to marketing stimuli. It is possible,
for example, that consumers high on EPO, who engage in
a thorough, balanced predecision outcome elaboration, will
be less likely to fall prey to deceptive advertising claims or
to be affected by decision biases like context or framing
effects.
On the one hand, we have argued conceptually and shown
empirically that EPO is a relatively stable individual trait.
On the other hand, we have shown that encouraging people
to think about potential consequences can improve self-regulation for individuals who do not normally engage in this
type of elaboration. This suggests that EPO tendencies can
temporarily be altered, perhaps through direct intervention
or via situational determinants. For example, EPO could be
affected by the context of a decision, and it might have
greater effects for high-involvement rather than low-involvement decisions, where decision makers tend to optimize time and effort (Einhorn and Hogarth 1981).
In addition to its important contributions and implications,
this research has surfaced some issues that merit further
research. For example, while our theoretical conceptualization proposed that consumers’ tendencies to generate a
variety of outcomes and to evaluate their likelihood and
importance should be measured separately, we were unable
to discriminate between these two dimensions empirically.
It seems that the tendencies to generate and evaluate outcomes are very closely related and equally predictive of
consumer information processing and decision making. Future research might examine the conditions under which
generation and evaluation of potential outcomes are not as
inextricably intertwined.
Our results (e.g., table 2) also suggest that the consideration of negative consequences has a bigger impact than
the consideration of positive consequences on evaluation
and generation. It may be natural for consumers to examine
the potential positive outcomes of a decision regardless of
context, while the tendency to also consider the potential
negative outcomes depends to some extent on the depth of
outcome elaboration. Thus, the key to effective self-regulation is to consider not only the possible upsides but also
the possible downsides. However, more work is needed to
better understand when both types of outcomes will be actively considered.
To establish EPO’s validity, we conducted a series of
studies to show its relationship to other existing constructs
and its ability to predict decisions and behaviors related to
self-regulation. However, validity testing of a newly established construct is an ongoing process. While we have shown
Effective self-regulation involves seeing the immediate
situation in terms of future concerns, values, and goals
(Carver and Scheier 1981). In this research, we have provided conceptual and empirical evidence that the proclivity
toward predecision outcome elaboration is an important determinant of self-regulation. Our research extends the literature on self-regulation by examining the effects of predecision processes on subsequent self-regulation. In spite of
the existence of individual differences in EPO and their
importance for the self-regulation of behavior, this construct
has not been examined sufficiently in past research, nor to
date has there been a good instrument to measure it. In this
article we conceptualize the construct and develop a psychometrically sound instrument that captures individual differences in EPO.
This research also extends the literature on expectations
about the future in several important respects. By incorporating different aspects of EPO—generation and evaluation
of consequences and focus on the positive versus negative
consequences—our conceptualization integrates diverse constructs that have previously attempted to depict the process
of outcome consideration. Past research on consideration of
potential outcomes has employed simple conceptualizations
of the construct or has focused on a single dimension of the
process, without the complicating influence of other dimensions. Examining these factors together provides a more
complete representation of the process people go through
when considering potential outcomes and allows researchers
to examine all aspects of this process.
Our proposed EPO scale reflects these different dimensions and provides a general and context-independent measure of EPO. The empirical results from several samples
confirm that the generation/evaluation and relative outcome
focus subscales of EPO capture distinct aspects of the outcome elaboration process and therefore relate to different
consumer traits and behaviors. In our studies, we consistently find that the people’s scores on the EPO scale generation/evaluation subscale are related to the depth of selfregulation, while their scores on the relative outcome focus
subscale are related to their self-regulation valence. We provide consistent evidence that consumers’ stronger tendencies
to generate and evaluate various potential consequences lead
to more effective self-regulation, while their relative positive
versus negative outcome focus gives rise to different strategic orientations.
From a theoretical standpoint, EPO could feasibly serve
as either an independent or a dependent variable in studies
of self-control and self-regulation. In our studies we focused
on the important domains of healthy lifestyle and money
management. Future research should continue to build on
these findings. One consumer domain where self-regulation
failure is particularly problematic is impulsive buying.
Americans tend to spend much more than they can afford,
resulting in significant amounts of consumer debt. Baumeister et al. (1994) point out that transcendence failure is
a central cause for excessive impulsive buying. Our results

here that EPO is related to yet distinct from a variety of
other psychological constructs such as impulsiveness, risk
aversion, need for cognition, and consideration of future
consequences, it might also be related to other consumerrelated constructs and phenomena. These potential relationships offer additional possibilities for future research. For
example, future research should continue to examine EPO
in relation to other self-regulation determinants such as selfefficacy (Bandura 1997), long-term planning (Morris and
Ward 2005), and ego depletion (e.g., Baumeister and Heatherton 1996). Effective self-regulation is central to consumer
welfare, and we need to better understand the underlying
forces in order to develop beneficial interventions. Predecision elaboration is a key ingredient in that solution.
