Motivational barriers to retention of at-risk young adults in HIV-prevention interventions: perceived pressure and efficacy.

Multi-session HIV-prevention interventions are efficacious but depend on the retention of clients over time. In a sample of at-risk young adults (N = 386), we investigated three potential motivational barriers that might affect the likelihood of retention. Perceived pressure, perceived efficacy and fear and anxiety during the initial session were measured, along with demographic characteristics, partner characteristics, and HIV-related health knowledge. Logistic regressions demonstrated that (1) in general, perceived ineffectiveness was negatively associated with retention; (2) perceived pressure or coercion was negatively associated with retention but only for younger clients; (3) experienced fear and anxiety had no significant association with retention. Implications for theory and counseling practices to reduce motivational barriers and effectively tailor interventions are discussed.
