HIV stigma negatively impacts prevention, testing, and treatment engagement. Systems science and causal loop diagrams visualize how stigma operates across care continua, identifying intervention points.
Area of Science:
- Public Health
- Systems Science
- Social Epidemiology
Background:
- HIV stigma undermines prevention and care, especially in disproportionately affected communities.
- Understanding stigma's complex role across the HIV care continuum is challenging.
- This study uses participatory systems science to map HIV stigma dynamics.
Purpose of the Study:
- To map the complex dynamics of HIV stigma across the HIV care continuum.
- To identify feedback loops and leverage points for stigma mitigation.
- To inform multi-level interventions for the Ending the HIV Epidemic (EHE) initiative.
Main Methods:
- Employed participatory systems science with stakeholders from health departments and community organizations.
- Conducted virtual group model building sessions to create causal loop diagrams (CLDs).
- Iteratively developed and validated CLDs representing HIV prevention, testing, and treatment.
Main Results:
- CLDs revealed feedback loops in personal health attitudes, service quality, and community influences.
- Internalized and enacted stigma weaken social support, resilience, and care quality.
- Community stigma is context-dependent, influenced by social isolation or inclusive norms.
Conclusions:
- Participatory systems methods effectively visualize how HIV stigma impacts care engagement.
- CLDs provide a framework for identifying intervention leverage points.
- Findings can guide multi-level interventions to reduce HIV stigma and advance EHE goals.
