Examination of Mediators and Moderators to Understand How and in What Context Game Changers Increases HIV Prevention Advocacy Among Persons Living With HIV in Uganda.

ABSTRACT:

Background

Our randomized controlled trial (RCT) of the group-based Game Changers intervention demonstrated effects on the primary goal of increased HIV-protective behaviors among social network members (alters), via the mechanism of increased participant engagement in HIV prevention advocacy with alters. We sought to understand how and in what context the intervention has its effects by examining specific mediators and moderators of the intervention's effect on increased prevention advocacy.

Methods

The RCT was conducted with 98 adult PLWH in Uganda. Intervention content targeted internalized HIV stigma, HIV disclosure, positive living behaviors, and self-efficacy for advocacy; these constructs were examined as intervention mediators (at the 5-month follow-up) of advocacy effects reported at the 8-month follow-up. Baseline sample characteristics were explored as moderators.

Results

Internalized HIV stigma and HIV disclosure mediated intervention effects on prevention advocacy, but not antiretroviral adherence or self-efficacy for advocacy. Moderators of the intervention effect included several network characteristics (trust in, support from, stigma from, and connectedness among network members), but not respondent socio-demographics or HIV disease characteristics. The intervention was associated with greater prevention advocacy when trust in, support from, and connectedness among alters were high, and stigma from alters was low.

Conclusions

These findings highlight the importance of helping PLWH cope with self-stigma and gain comfort with disclosure, as well as the potential influence of network support, trustworthiness, connectedness, and stigmatization on engagement in prevention advocacy.

Project description:IntroductionCervical cancer (CC) rates are high in Uganda, yet CC screening rates are very low. Our peer advocacy group intervention, Game Changers for Cervical Cancer Prevention (GC-CCP), was shown to increase CC screening uptake among social network members. In this secondary analysis, we examined mediators and moderators of this effect to better understand how and for whom the intervention was most successful in promoting CC screening.MethodsWe conducted a pilot randomized controlled trial of GC-CCP in Namayingo district, Eastern Uganda between September 2021 and April 2022. Forty adult women who had screened for CC in the past year (index participants) enrolled at baseline: 20 were randomized to receive the 7-session intervention to empower women to engage in CC prevention advocacy, and 20 were assigned to the waitlist control; from these index participants, 103 unscreened social network members (alters) also enrolled. All participants were assessed at baseline and month 6 follow-up. Change in cognitive and behavioral CC-related constructs from baseline to month 6 were examined as mediators, using multivariate linear regression analysis. Index and alter demographics and index CC treatment status were examined as moderators.ResultsIncreased alter engagement in CC prevention advocacy fully mediated the intervention effect on alter uptake of CC screening, and was associated with an increased likelihood of alter CC screening. CC treatment status of the index participant was the sole moderator of the intervention effect, as those in the intervention group who had screened positive and received treatment for pre-cancerous lesions were more likely to have alters who got screened for CC by month 6.ConclusionThe effect of GC-CCP on alter CC screening is greater when the alter reports increased engagement in her own advocacy for CC prevention with others. The intervention effects on increased engagement in CC prevention advocacy among both index and alter participants suggest a diffusion of advocacy, which bodes well for dissemination of knowledge and screening activation throughout a network and the larger community.

Project description:IntroductionCervical cancer (CC) is the leading cause of cancer-related deaths among Uganda women, yet rates of CC screening are very low. Training women who have recently screened to engage in advocacy for screening among women in their social network is a network-based strategy for promoting information dissemination and CC screening uptake.MethodsDrawing on the Exploration, Preparation, Implementation and Sustainment (EPIS) framework for implementation science, this hybrid type 1 randomized controlled trial (RCT) of a peer-led, group advocacy training intervention, Game Changers for Cervical Cancer Prevention (GC-CCP), will examine efficacy for increasing CC screening uptake as well as how it can be implemented and sustained in diverse clinic settings. In the Preparation phase we will prepare the four study clinics for implementation of GC-CCP and the expected increase in demand for CC screening, by using qualitative methods (stakeholder interviews and client focus groups) to identify and address structural barriers to easy access to CC screening. In the Implementation phase, GC-CCP will be implemented over 36 months at each clinic, with screened women (index participants) enrolled as research participants receiving the intervention in the first 6 months as part of a parallel group RCT overseen by the research study team to evaluate efficacy for CC screening uptake among their enrolled social network members. All research participants will be assessed at baseline and months 6 and 12. Intervention implementation and supervision will then be transitioned to clinic staff and offered as part of usual care in the subsequent 30 months as part of the Sustainability phase. Using the RE-AIM framework, we will evaluate engagement in GC-CCP and CC advocacy (reach), alter CC screening (effectiveness), adoption into clinic operations, implementation outcomes (acceptability, feasibility, fidelity, cost-effectiveness) and maintenance.DiscussionThis is one of the first studies to use a network-driven approach and empowerment of CC screened peers as change agents to increase CC screening. If shown to be an effective and sustainable implementation strategy for promoting CC screening, this peer advocacy model could be applied to other preventative health behaviors and disease contexts.Trial registrationNIH Clinical Trial Registry NCT06010160 (clinicaltrials.gov; date: 8/17/2023).
