title: Individual drinking changes following a brief intervention among college students: clinical significance in an indicated preventive context.
abstract: This study investigated the clinical significance of previously reported statistically significant mean reductions in drinking and related problems among college students in a randomized trial of a brief indicated preventive intervention (G. A. Marlatt et al., 1998). Data were analyzed over a 2-year follow-up for participants from a high-risk intervention group (n = 153), a high-risk control group (n = 160), and a functional comparison group (n = 77). A risk cutpoint for each dependent measure was based on the functional comparison group distribution. Compared with the high-risk controls, more individuals in the high-risk intervention group improved and fewer worsened, especially on alcohol-related problems and, to a lesser extent, on drinking pattern variables. These data from a prevention context clarify the magnitude and direction of individual change obscured by group means.
