We chose six MI sessions (30%) at random and transcribed them, and a trained independent evaluator
ranged from 3.33 to 4.33, with an average of 3.73 (standard deviation [SD] = 0.34). Although one session was rated below the recommended 3.5 threshold for beginning proficiency in MI (Moyersetal.,2010),average ratings for both therapists were above this threshold.These ratings suggest the MI therapists were generally proficient in maintaining the “MI spirit.”
