Note. MIA: STEP = Motivational Interviewing Assessment: Supervisory Tools for Enhancing Proficiency, SAU = Supervision-as-Usual. Adherence was rated 1 = not at all, 2 = a little, 3 = infrequently, 4 = somewhat, 5 = quite a bit, 6 = considerably, 7 = extensively. Competence was rated 1 = very poor, 2 = poor, 3 = acceptable, 4 = adequate, 5 = good, 6 = very good; 7 = excellent. The random effect of site is nested in training condition within the hierarchical linear regression models. A familywise alpha of p <.01 (.05/5) marked significant effects.
