The positive affect, promoting Positive Engagement, and Adherence for Life (APPEAL) feasibility trial: Design and rationale

Synergistic Opportunities for Affective Science and Behavior Change

Behavior change can be challenging to facilitate and achieve. Behavior change frameworks largely focus on social cognitive determinants, omitting affective determinants or including them in a superficial way. However, evidence points to the role of affect in decision-making and behavior, particularly when the behavior at focus for change is affectively pleasant or when the behavior to be facilitated is affectively unpleasant. This paper identifies challenges and opportunities to further affective science by using behavior change as a context and, relatedly, to further the science of behavior change by leveraging theoretical and methodological innovations in affective science.

Four-Year Trajectories of Internal Strengths and Socioemotional Support Among Middle-Aged and Older Adults with HIV

Positive psychological attributes are associated with better health outcomes, yet few studies have identified their underlying constructs and none have examined their temporal trajectories in clinical vs. non-clinical samples. From data collected over 4 years from people with HIV (PWH) and HIV-uninfected (HIV-) participants, we identified two latent factors (internal strengths; socioemotional support) based on responses to seven positive psychological attributes. Internal strengths increased over 4 years for PWH, but not for HIV- comparisons. Socioemotional support did not change significantly in either group. Lower internal strengths and worse socioemotional support were related to greater depressive symptoms. We speculate that improvement in internal strengths in PWH could reflect their being in care, but this requires further study to include PWH not in care. Given the apparent malleability of internal strengths and their association with improved health outcomes, these attributes can serve as promising intervention targets for PWH.

"He is the Same as Me": Key Populations' Acceptability and Experience of a Community-Based Peer Navigator Intervention to Support Engagement in HIV Care in Tijuana, Mexico

Engagement in the HIV care continuum among people living with HIV is essential to prevent ongoing transmission. Although there is evidence for the need for comprehensive approaches (e.g., peer navigation) to improve the HIV care continuum, there is limited knowledge of how the peer navigation model might work to improve the HIV care continuum in low resource settings among Latinx key populations (e.g., persons who inject drugs, female sex workers, men who have sex with men, and transgender women). Therefore, this article aims to qualitatively assess members of key populations' acceptability of Conexiones Saludables (Healthy Connections), a community-based peer navigation intervention implemented in Tijuana, Mexico. This analysis draws upon the postintervention survey data from 34 participants and data from qualitative interviews with 10 participants. Participants found the intervention to be acceptable and discussed the ways in which peer navigators were influential in educating participants about HIV, antiretroviral therapy (ART), linking participants to existing HIV care and ancillary services in Tijuana, and in providing emotional and instrumental support to facilitate engagement in HIV treatment and ART adherence. The intervention emphasized the use of peer navigators who had a deep understanding of the sociostructural barriers (e.g., substance use, homelessness) that HIV-positive key populations face in Tijuana. Findings from this study may inform programs with highly vulnerable populations in similar settings.
