title: Changes in ambivalence mediate the relation between entering treatment and change in alcohol use and problems.
abstract: The present study examined the role of ambivalence about change as (1) a predictor of subsequent heavy alcohol use and drinking problems and (2) a mediator of change between entering treatment and heavy alcohol use and drinking problems among individuals self-referring for treatment with an alcohol use disorder. A sample of 439 individuals (49.9% female) who initiated help-seeking was surveyed at baseline, and at 1 year and 3 year follow-ups on domains of alcohol-related and personal functioning. A series of regression analyses indicated that a measure reflecting ambivalence significantly predicted subsequent heavy alcohol use and related problems and mediated changes between entering treatment and heavy alcohol use and related problems. The findings highlight one mechanism associated with treatment seeking, initiation of and engagement in treatment, and reduction in heavy alcohol use and related problems.
