Tailored Motivational Interviewing in Adolescent HIV Clinics: Primary Outcome Analysis of a Stepped Wedge...

Youth continue to have the poorest outcomes along the HIV prevention and care continua. Motivational Interviewing (MI) may promote behavior change and reduce perceived stigma, but providers often demonstrate inadequate MI competence. This study tested Tailored Motivational Interviewing (TMI), a set of implementation strategies designed to improve MI competence in youth HIV providers.

Ten HIV clinics in the Adolescent Trials Network for HIV/AIDS Interventions.

In a stepped wedge design, 10 clinics (N = 151 providers) were randomized in 5 clusters every 3 months to receive TMI for a 12-month implementation period. Sites were rerandomized within each cluster to receive communities of practice guidance with or without internal facilitator support in the sustainment period. Standard patient assessments were coded every 3 months for 36 months.

Nesting was addressed using mixed-effects regression models, with random effects for providers and sites. TMI resulted in significantly improved MI competence over baseline. Despite small reductions in competence in the sustainment window, competence was still significantly improved over baseline, with no difference between the 2 sustainment conditions.

TMI may be an important tool to capacitate the HIV HealthForce to end the HIV epidemic in young people.
