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 (rhos>.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.

Context Advances in antiretroviral therapy (ART) for HIV offer life-extending benefit; however, the side effects associated with ART use negatively impact quality of life and medication adherence among people living with HIV. Objectives This study tested the efficacy of mindfulness-based stress reduction (MBSR) for reducing ART symptoms and bother/distress related to ART side effects. Secondary aims were to test the impact of MBSR on medication adherence and psychological functioning. Methods Seventy-six people living with HIV who were actively taking ART and reported distress from ART-related side effects were randomly assigned to MBSR or a wait-list control standard care condition. We measured side effects, ART adherence, perceived stress, depression, positive and negative affect, and mindfulness at three time points: baseline, three-month follow-up, and six-month follow-up. Side effects and related distress were assessed separately from other symptoms. Results Compared to a wait-list control, participants in the MBSR condition experienced a reduction in the frequency of symptoms attributable to antiretroviral therapies at three months post intervention (mean difference = 0.33; 95% confidence interval [CI] = 0.01, 0.66; t(132) = 2.04, P = 0.044) and at six months post intervention (mean difference = 0.38; 95% CI = 0.05, 0.71; t(132) = 2.27, P = 0.025). MBSR participants also experienced a reduction in distress associated with those symptoms at three months post intervention (mean difference = 0.47; 95% CI = 0.003, 0.94; t(132) = 1.99, P = 0.048) compared with the wait-list control condition. Conclusion Mindfulness-based stress reduction is a promising approach for reducing HIV treatment-related side effects.

To identify factors associated with antiretroviral therapy (ART) adherence and virologic control among HIV-positive men on ART in primary relationships, data were collected from 210 male couples (420 men). Dyadic actor–partner analyses investigated associations with three levels of adherence-related dependent variables: self-efficacy (ASE), self-reported adherence, and virologic control. Results indicated that higher patient ASE was related to his own positive beliefs about medications, higher relationship autonomy and intimacy, and fewer depressive symptoms. Fewer depressive symptoms and less relationship satisfaction in the partner were linked to higher ASE in the patient. Better self-reported adherence was related to the patient’s positive appraisal of the relationship and the partner’s positive treatment efficacy beliefs. Greater medication concerns of both patient and partner were associated with less adherence. The partner’s higher relationship commitment was associated with lower viral load in the patient. Findings suggest that depressive symptoms, treatment beliefs, and relationship quality factors of both partners may influence adherence-related outcomes.

The Health Care Empowerment Model offers direction for the investigation of patient-controlled engagement and involvement in health care. At the core of the model is the construct of Health Care Empowerment (HCE), for which there exist no validated measures. A set of 27 candidate self-report survey items was constructed to capture five hypothesized inter-related facets of HCE (informed, engaged, committed, collaborative, and tolerant of uncertainty). The full item set was administered to 644 HIV-infected persons enrolled in three ongoing research studies. Exploratory and confirmatory factor analyses resulted in a two factor solution comprising four items each on two subscales: (1) HCE: Informed, Committed, Collaborative, and Engaged HCE ICCE) and (2) HCE Tolerance of Uncertainty (HCE TU). Subscale scores were evaluated for relationships with relevant constructs measured in the three studies, including depression, provider relationships, medication adherence, and HIV-1 viral load. Findings suggest the utility of this 8-item Health Care Empowerment Inventory (HCEI) in efforts to measure, understand, and track changes in the ways in which individuals engage in health care.
