Abstract
Adherence to HIV treatment, including adherence to antiretroviral (ART) medication regimens, is paramount in the management of HIV. Self-efficacy for treatment adherence has been identified as an important correlate of medication adherence in the treatment of HIV and other medical conditions. This paper describes the validation of the HIV Treatment Adherence Self-Efficacy Scale (HIV-ASES) with two samples of HIV+ adults on ART. Factor analyses support subscales measuring Adherence Integration (eigenvalue = 6.12) and Adherence Perseverance (eigenvalue = 1.16), accounting for 61% of the variance in scale items. The HIV-ASES demonstrates robust internal consistency (ρs > .90) and 3-month (rs > .70) and 15-month (rs > .40) test–retest reliability. Concurrent validity analyses revealed relationships with psychosocial measures, ART adherence, clinical status, and healthcare utilization. Findings support the use of the HIV-ASES and provide guidance for further investigation of adherence self-efficacy in the context of treatment for HIV and other diseases.

Appendix. HIV-ASES Items
Appendix. HIV-ASES Items
I am going to ask you about situations that could occur during your treatment for HIV. Treatment can involve different things for different people. Sometimes, this might refer to taking medications, and other times it could refer to other things that you do to deal with HIV such as diet and exercise or taking vitamins. So, in these questions, when I ask you about your “treatment” or your “treatment plan,” I am talking not only about any medications that you might be taking for HIV, but also other things that make up your self-care.
For the following questions I will ask you to tell me in the past month, including today, how confident you have been that you can do the following things. Use this response scale ranging from 0 (“cannot do at all”) to 10 (“completely certain can do”).
[Note: The term “clinic” may be replaced by “doctor’s office” if participant does not receive care in clinic settings.]
Cannot do at all | 00 |
01 | |
02 | |
03 | |
04 | |
Moderately certain can do | 05 |
06 | |
07 | |
08 | |
09 | |
Completely certain can do | 10 |
In the past month, how confident have you been that you can:
-
1.
Stick to your treatment plan even when side effects begin to interfere with daily activities?
-
2.
Integrate your treatment into your daily routine?
-
3.
Integrate your treatment into your daily routine even if it means taking medication or doing other things in front of people who don’t know you are HIV-infected?
-
4.
Stick to your treatment schedule even when your daily routine is disrupted?
-
5.
Stick to your treatment schedule when you aren’t feeling well?
-
6.
Stick to your treatment schedule when it means changing your eating habits?
-
7.
Continue with your treatment even if doing so interferes with your daily activities?
-
8.
Continue with the treatment plan your physician prescribed even if your T-cells drop significantly in the next three months?
-
9.
Continue with your treatment even when you are feeling discouraged about your health?
-
10.
Continue with your treatment even when getting to your clinic appointments is a major hassle?
-
11.
Continue with your treatment even when people close to you tell you that they don’t think that it is doing any good?
-
12.
Get something positive out of your participation in treatment, even if the medication you are taking does not improve your health?
