Note. MET = motivational enhancement therapy delivered across three sessions within a 4-week period; CAU = counseling-as-usual delivered in an equivalent manner to MET; ICC = intraclass correlation coefficients based on the Shrout and Fleiss (1979) two-way mixed model.

a

Adherence ratings are on a 7-point Likert scale: 1=not at all, 2=a little (once), 3=infrequently (twice), 4=somewhat (3-4 times), 5=quite a bit (5-6 times), 6=considerably (> 6 times/more depth in interventions), 7=extensively (high frequency/characterizes entire session). Mean adherence ratings are based on the 206 MET and 219 CAU sessions.

b

Competence rating are on a 7-point Likert scale: 1= very poor, 2=poor, 3=acceptable, 4=adequate, 5=good, 6=very good, 7 = excellent). Mean competence ratings are made only when an item occurs within a session. Thus, the sample sizes for the item competence ratings vary considerably from n = 3 for skills training to n = 202 for open-ended questions, both in the MET condition.
