N2  - This study tested technical and relational processes hypothesized to explain the therapeutic benefit of an efficacious brief motivational interview (BMI). A randomized controlled trial compared the efficacy of a BMI to an attention-matched control (i.e., relaxation training [REL]) for reducing heavy alcohol consumption and associated negative consequences. Participants were underage, past-month heavy drinkers recruited from community settings (N = 167; ages 17-20; 62% female; 59% White). Data were collected on session recordings, using established motivational interviewing process measures. Statistical analyses followed 3 steps. First, a latent class model determined the optimal class solution for characterizing proportion change talk means within BMI and REL. Next, the probability of proportion change talk class membership was examined as a mediator and then as a moderated mediator of BMI efficacy. The latent class model yielded a 3-class solution, including a low-increasing proportion change talk class (n = 61), a moderate-increasing proportion change talk class (n = 97), and a nonlinear proportion change talk class (n = 7). Across the outcomes examined, membership in the moderate-increasing class rather than the low-increasing class mediated BMI effects on alcohol-related consequences at 6 weeks. Mediation tests for consequences at 3 months and heavy drinking were nonsignificant. Moderated mediation results for therapist empathy and MI Spirit were nonsignificant. <br><br>FINDINGS suggest that moderate increases in prochange statements, relative to anti- or neutral-change statements, help explain BMI effects on reducing alcohol-related negative consequences soon after intervention.
