Relations between provider adherence to a tailored motivational intervention protocol and competence in motivational interviewing

Objectives: To evaluate the association between provider adherence to Tailored Motivational Interviewing implementation strategy and motivational interviewing (MI) competence. Methods: 156 youth-focused HIV providers enrolled in a parent implementation science trial completed: a) quarterly standardized patient assessments (SPI) during Baseline; b) a workshop, individual coaching sessions, and quarterly SPI plus feedback during Implementation; and c) quarterly SPI during Sustainment. Competence was measured using the MI-CRS and tracking data was used to assess adherence. We examined overall adherence as well as adherence to each implementation strategy in relation to MI competence. Results: Overall adherence was not associated with overall MI competence. MI competence significantly increased from Baseline to Implementation and Baseline to Sustainment. Some individual implementation strategies were associated with change in competence and the probability of achieving Intermediate/Advanced competence. Conclusions: The results suggest that 100% percent adherence to all TMI implementation strategies may not be necessary. Completing some of the TMI implementation strategies yielded improvements in MI competence. The use of routine tracking data to measure adherence maybe more pragmatic than using observational coders and more objective than self-reports. Practice implications: In busy HIV clinics, MI training should focus on strategies most directly associated with increased provider competence.
