Scales to Assess Knowledge, Motivation, and Self-Efficacy for HIV PrEP in Colombian MSM: PrEP-COL Study.

ABSTRACT:

Objective

We evaluated the construct validity Spanish version of knowledge, stigma, norms, and self-efficacy scales regarding PrEP in MSM.

Methods

Sample of 287 MSM. Exploratory confirmatory factor analysis and item response theory were used to validate the constructs. Correlations and confidence interval-based estimation of relevance analyses were conducted to correlate the scales with willingness and intention to use PrEP.

Results

Attitude, stigma, and descriptive and subjective norms scales showed good construct validity and were related to intention and willingness to use PrEP. However, the knowledge scale and self-efficacy scales require further refinement.

Conclusions

The study provides useful information for assessing information, motivation, and self-efficacy related to PrEP use. Our results could be used to test the scales and the theoretical model in other contexts to confirm their usefulness.

Project description:PurposeDisparities persist in HIV infection among Black and Latino men who have sex with men (BLMSM) and Black and Latina transgender women (BLTW). Increasing uptake and subsequent consistent use of pre-exposure prophylaxis (PrEP), an effective biomedical strategy for preventing HIV acquisition, can dramatically reduce HIV incidence in these populations. The purpose of this study was to explore reasons for PrEP discontinuation among BLMSM and BLTW living in Los Angeles County to inform the development of support services for these populations to remain persistent with their PrEP regimen.MethodsIn-depth, semi-structured interviews were conducted with 15 BLMSM and 7 BLTW who reported either temporary or indefinite PrEP discontinuation. A thematic analysis approach was used to analyze qualitative data.ResultsFour themes emerged related to reasons for PrEP discontinuation, including: (1) lower perceived HIV risk related to changes in sexual behavior; (2) structural or logistical barriers (e.g., lapse or loss of health insurance, cost, difficulty navigating complex medical systems); (3) anticipated and experienced medication side effects, with a sub-theme of interactions between PrEP and feminizing hormone medications; and (4) challenges with medication adherence.ConclusionsPrEP is an important prevention tool for BLMSM and BLTW, particularly during periods of heightened HIV risk. However, both individual (e.g., inability to adhere to medication, changes in HIV sexual risk behaviors) and structural/logistical (e.g., loss of insurance, navigating complex medical systems) factors can cause temporary or indefinite PrEP discontinuation. Additional support services, beyond those offered by medical providers, are needed to help BLMSM and BLTW PrEP users overcome barriers to discontinuation and assist them to remain persistent with their PrEP regimen. We describe potential options for support services such as PrEP case management, expanded PrEP navigation services, or text messaging services.
