Tailored Motivational Interviewing Implementation Intervention (TMI) Effectiveness Trial in Multidisciplinary Adolescent HIV Care Settings

ATN 146 Tailored Motivational Interviewing Implementation Intervention (TMI) was tested in multidisciplinary adolescent HIV care settings. TMI is an evidence-based practice for patient-provider communication and behavior change. Aims were to determine its effect on provider fidelity, HIV cascade-related outcomes, sustainment fidelity, implementation barriers and facilitators, and cost effectiveness. A Dynamic Wait-list controlled design was used to deliver TMI in community-based settings (190 providers enrolled across 10 sites). The intervention included a group workshop, individual coaching, and quarterly competency assessments. It was hypothesized that MI competency would be higher during the intervention phase than baseline, and successful implementation would be associated with improved cascade-related outcomes. TMI demonstrated significantly higher competence during the intervention phase, maintained with only small reductions through the sustainment window. Analyses are underway for cascade-related outcomes.
