Abstract:
Research shows that persons living with HIV (PLWHIV) question whether their prescribed antiretroviral regimen will be effective and whether adhering to the regimen is worth the effort. Bandura's self-efficacy theory provides a basis for understanding adherence behavior; however, there is no standard measure to assess self-efficacy in PLWHIV. Thus, the purpose of this study was to evaluate the psychometric properties of the HIV Self-Efficacy Scale (HIV SES) developed by the researchers for use in a randomized clinical trial testing the effects of a telephone delivered intervention on adherence. The 26 item HIV SES assesses level of self-rated confidence from 1 (not confident) to 10 (totally confident); 17 items comprise the Self-Efficacy Beliefs (SEB) subscale and 9 items comprise the Outcome Expectancies (OE) subscale. The items were developed based on a review of the literature and data obtained from previous qualitative research with PLWHIV. The sample of 81 PLWHIV who completed the HIV SES included 55 men (68%) and 26 women (32%) ranging in age from 19-61 years. The ethnic distribution was 53 (65%) whites and 28 (35%) nonwhites. Internal consistency reliability showed an alpha coefficient of .95 for the entire scale and for the SEB and OE subscales. Test-retest at 12 weeks on 28 nonintervention subjects demonstrated a moderate correlation of .45 (p=.01). Validity of the HIV SES was assessed using the Self-Reported Medication Adherence Scale and the Interpersonal Support Evaluation List (ISEL). The HIV SES was weakly associated with the Self-Reported Medication Adherence Scale. Significant moderate associations were demonstrated between the HIV SES and the ISEL: r=.45 (p=.00) total scale; r=.41 (p=.00) SEB subscale; and r=.31 (p=.00) OE subscale. Examining gender, race, and risk factor for HIV showed no significant differences between race and risk factor and the HIV SES scores; however, gender showed a significant difference on the SEB subscale (p=.03) with men scoring higher. There were significant negative associations between regimen complexity (r=-.22, p=.05) and impact of side effects (r=-.32, p=.00) and the SEB subscale. The HIV SES shows promise for use in studies assessing self-efficacy in PLWHIV. Further evaluation of the HIV SES using a larger sample is needed to confirm its psychometric properties. Knowledge of self-efficacy will assist researchers to develop and test targeted interventions to promote medication adherence.
