The importance of domain-specific self-efficacy assessment for substance use and HIV care continuum outcomes among adults in an urban HIV clinic network

Interest in and Willingness to Use PrEP: A Cross-Sectional Study of Individuals with Problematic Substance Use Residing in a High HIV Prevalence Jurisdiction

Although it is an effective HIV prevention method, pre-exposure prophylaxis (PrEP) is underutilized in the Southern US. Many people who use drugs (PWUD) have increased susceptibility to HIV which could be lessened by using PrEP. Potential barriers to PrEP use include lack of awareness of PrEP, low knowledge about HIV prevention, low self-efficacy for HIV prevention, inaccurate risk perceptions, and anticipated stigma. The current study examined predisposing, enabling, and reinforcing factors that may predict interest in PrEP. The purpose of the current study was to explore factors associated with interest in and willingness to use daily oral and long acting injectable PrEP among sexually active adult PWUD. The data were collected from adult participants (n = 270) residing in Harris County, TX, who self-reported problematic substance use and who reported oral, anal, or vaginal sex in the six months prior to completing the survey. The survey was distributed and completed online via Qualtrics Panels in March of 2022 and included measures of PrEP and HIV knowledge, PrEP stigma, sexual health self-efficacy, experiences of discrimination, health literacy, and medical mistrust. The majority of participants reported circumstances or behaviors that increased their susceptibility to HIV. Findings indicated that PrEP user stereotypes and PrEP anticipated disapproval by others were associated with interest in using daily oral PrEP and willingness to use long acting injectable PrEP. These results provide insight into reasons for low PrEP uptake among PWUD who live in a high HIV prevalence jurisdiction. Implications for HIV prevention intervention are discussed.

Behavioral and psychosocial predictors of self-efficacy for managing chronic disease among people living with HIV: forgiveness, life perspective, and social support

HIV medication can help people living with HIV (PLWH) live longer, but many PLWH still report difficulty managing their disease and report engaging in harmful behaviors to themselves and others, which have adverse downstream consequences. Self-efficacy is predictive of positive health behaviors and outcomes, and it is modifiable through interventions. While existing studies overwhelmingly examine self-efficacy among PLWH, much fewer studies focus on self-efficacy for managing HIV, including self-efficacy for managing physical and psychological health problems caused by HIV-common problems that PLWH experience. Additionally, only limited literature on other-forgiveness and life perspective among PLWH exists. Thus, we further examine predictors of self-efficacy for managing HIV. We hypothesize that other-forgiveness, positive life perspective, and social support significantly predict self-efficacy for managing HIV after controlling for demographic variables. The results show that the overall multiple linear regression model significantly accounted for 38% of the variance in self-efficacy for managing HIV. Additionally, other-forgiveness was as powerful at predicting self-efficacy as social support; moreover, positive life perspective was a significant and the most powerful predictor of self-efficacy. These findings indicate that other-forgiveness and positive life regard may be as important, if not more so, than social support to chronic disease management.
