We addressed these questions by decomposing negative affect and positive affect variance across three levels (person, day, moment), and calculating reliability using a coordinated analysis of seven daily diary, ecological momentary assessment (EMA), and diary-EMA hybrid studies (across studies age = 18-84 years, total N = 2,103, total N = 45,065). Across studies, within-person variance was sizeable (negative affect: 45% to 66%, positive affect: 25% to 74%); in EMA more within-person variance was attributable to momentary rather than daily level. Reliability was adequate to high at all levels of analysis (within-person: .73-.91; between-person: .96-1.00) despite different items and designs. We discuss the implications of these results for the design o...

Existing research from ecological momentary assessment and end-of-day daily diary studies examining such age-related benefits have yielded mixed results, potentially due to differences in samples, design, and measurement of everyday stressors and negative affect. We conducted a coordinated analysis of 5 ecological momentary assessments and 2 end-of-day daily diary studies to examine adult age differences in the within-person association between everyday stressors and negative affect. Reported stressor occurrences are robustly associated with higher negative affect, regardless of study design and sample characteristics. Across studies, interactions between age and everyday stressors predicting negative affect revealed a pattern of age-related decreases in the stres...

We investigate the association between early-life adversity and the dynamic range of adult diurnal cortisol secretion. Method In 35- to 86-year-old adults, cortisol assayed from 16 saliva samples over 4 consecutive days was used to compute diurnal dynamic range and area under the curve (AUC). Economic adversity in childhood was indexed by recalled parental education, family welfare dependence, and perceived financial status; and childhood social adversity by parental separation, death, and abuse. Results Adjusted for age, gender, and race/ethnicity, both childhood adversities were strongly associated with smaller adult cortisol diurnal dynamic range, but not with AUC. The association with cortisol dynamic range was explained by adult social ...

This study examined the day-to-day linkages between time resources (assessed by time use and perceived time adequacy for parenting, partner, and personal roles) and daily well-being and tested whether a workplace intervention enhanced the linkages. Participants were employed, partnered parents in the information technology division of a large US firm and who provided eight-day diary data at two times ( = 90). Multilevel modeling revealed that, on days when parents perceived lower time adequacy than usual for the three roles, they reported less positive affect, more negative affect, and more physical symptoms, independent of time spent in the roles. Moreover, a workplace intervention designed to give employees more temporal flexibility and support for family responsibilities increased daily time spent with the focal child and increased perceived time adequacy for exercise. The intervention al...

This study investigated the frequency with which women employed in U.S.-based nursing homes entered and exited unpaid caregiving roles for children (double-duty-child caregivers), adults (double-duty-elder caregivers), or both (triple-duty caregivers), as well as examined how combinations of and changes in these caregiving roles related to cross-sectional and longitudinal sleep patterns. The sample comprised 1,135 women long-term care employees who participated in the baseline wave of the Work, Family, and Health Study and were assessed at three follow-up time points (6-, 12-, and 18-months). Sleep was assessed with items primarily adapted from the Pittsburgh Sleep Quality Index and wrist actigraphic recordings. Multilevel models with data nested within persons w...

Less is known about whether multiple positive attributes of sleep health known as the SATED (satisfaction, alertness, timing, efficiency, and duration) model, can decrease future cardiovascular disease risks. We examined whether and how a variety of indicators of sleep health predicted 10-year estimated cardiometabolic risk scores (CRS) among employed adults. Workers in two industries-extended care (n = 1,275) and information technology (IT; n = 577)-reported on habitual sleep apnea symptoms and sleep sufficiency, and provided 1 week of actigraphy data including nighttime sleep duration, wake after sleep onset (WASO), sleep timing, and daytime napping. Workers also provided biomarkers to calculate future cardiometabolic risk. More sleep apnea symptoms predicted higher CRS in both industries. More sleep sufficiency, less WASO, and less daytime napping (having no naps, fewer naps, and shorter nap du...

The current study extends this research to real life, and examines whether daily physical activity attenuates negative affect that occurs in response to naturally occurring daily stressors. The current study used data from the second wave of the National Study of Daily Experiences, a sub-study of the second wave of the Midlife in the United States Study (MIDUS-II) of 2,022 individuals aged 33-84 questioned nightly for eight consecutive days about their general affect and affective responses to stressful events and their engagement in physical activity. Results indicated that while negative affect is significantly elevated on days with stressful events compared to days free of events in all individuals, these effects are attenuated in those who remain physically active when compared to those who were underactive. This ...

In accordance with the Science of Behavior Change (SOBC) program, we apply an experimental medicine approach to identifying stress response targets, developing stress response assays, intervening upon these targets, and testing intervention effectiveness. We evaluate an ecologically valid, within-person approach to measuring the deleterious effects of everyday stress on physical activity and sleep patterns, examining multiple stress response components (i.e., stress reactivity, stress recovery, and stress pile-up) as indexed by two key response indicators (negative affect and perseverative cognition). Our everyday stress response assay thus measures multiple malleable stress response targets that putatively shape daily health behaviors (physical activity and sleep). We hypothesize that larger reactivity, incomplete recove...

The moderating effects of perceived family time adequacy were also evaluated. Regression analyses were conducted on survey data from 972 CNAs working in U.S.-based nursing homes. Compared with workplace-only caregivers, double-and-triple-duty caregivers reported more emotional exhaustion and pressure to make family sacrifices for the sake of work. Triple-duty caregivers also reported less job satisfaction. Perceived family time adequacy buffered double-duty-child and triple-duty car...

Using a person-centered latent profile approach, we identified 3 profiles of time use and perceived time adequacy in a sample of mothers employed in the extended-care industry (N = 440): a Work-Oriented profile, characterized by spending relatively more time at work, perceiving lower time adequacy for work, spending less time with children, and perceiving lower time adequacy for children; a Parenting-Oriented profile, characterized by the opposite pattern; and a Role-Balanced profile, characterized by average levels across the 4 dimensions. Mothers in the Work-Oriented profile reported greater work-to-family conflict and family to-work conflict than those in the Role-Balanced and Parenting-Oriented profiles. Greater work-to-family conflict was linked to membership in ...

Strength and vulnerability integration (SAVI; Charles, 2010) theory postulates that age differences in emotional states are contingent upon whether a stressor occurred, and whether sufficient time has passed since the stressor to allow older adults to benefit from theorized strengths. The present study uses an ecological momentary assessment design to examine how timing of daily stressors relates to age differences in negative emotional responses. Participants (N = 199, aged 25-65) completed mobile surveys up to 5 times daily for 14 days. They reported current mood and stressor exposure, as well as how long ago the stressor occurred. As expected, no age differences were observed in current negative affect (NA) for stressors which occurred in the previous 0-10 min. As predicted, older age was associated wi...

We built upon prior studies of the correlates of sleep, which have relied primarily on cross-sectional data, to examine the antecedents and consequences of sleep using a daily diary design. Specifically, we assessed the temporal sequence between nightly sleep and daily psychosocial stressors. Parents employed in a US information technology company (n = 102) completed eight consecutive daily diaries at both baseline and 1 year later. In telephone interviews each evening, participants reported on the previous night's sleep hours, sleep quality and sleep latency. They also reported daily work-to-family conflict and time inadequacy (i.e. perceptions of not having enough time) for their child and for themselves to engage in exercise. Multi-level models testing lagged and non-lagged effects simultaneously revealed that sleep hours and sleep quality were associated with next-day consequences of work...

Adolescents completed daily diary reports of family demands and conflict for 15 days, and wore actigraph watches during the first 8 nights to assess sleep. Participants also provided five saliva samples for 3 consecutive days to assess diurnal cortisol rhythms. Regression analyses indicated that sleep latency and efficiency moderated the link between family demands and the cortisol awakening response. Specifically, family demands were related to a smaller cortisol awakening response only among adolescents with longer sleep latency and lower sleep efficiency. These results suggest that certain aspects of HPA axis functioning may be sensitive to family demands primarily in the context of longer sleep latency and lower sleep efficiency.

We also tested whether youth gender and parental warmth moderated these linkages. Participants were the children of employees in the information technology division of a large company (N = 132, mean age = 13.39 years, 55% female). Youth completed daily diary telephone interviews on 8 consecutive evenings and provided saliva samples at 4 time points over 4 days to assess daily stressors and youth physiological and affective functioning. Parental warmth was assessed during in-home interviews. Multilevel modeling was used to account for interdependencies in the data. Youth who experienced more daily stressors, on average, reported more negative affect and physical health symptoms, on average. Furthermore, on days youth reported more stressors than usual (compared to their own across-day average), they also exhi...
