Effect of Middle School Interventions on Alcohol Misuse and Abuse in Mexican American High School AdolescentsFive-Year Follow-up of a Randomized Clinical Trial

摘要

P ?=?.047; odds ratio, 0.39). Intervention associations with past-year alcohol use frequency, binge drinking, and drunkenness were moderated by baseline substance use. The intervention reduced the frequency of alcohol use (β?=??.51; SE, 0.24; P ?=?.04; Cohen d ?=?0.43) and drunkenness (β?=??.51; SE, 0.26; P ?=?.049; Cohen d ?=?0.41) among youth who reported any previous substance use at baseline (T1 initiators) but not among those who had not initiated any substance use (T1 abstainers) at baseline. For past-year binge drinking, the intervention finding did not reach statistical significance among T1 initiators (β?=??.40; SE, 0.23; P ?=?.09) or T1 abstainers (β?=?.23; SE, 0.14; P ?=?.11). Conclusions and Relevance ? Study results support an association between a universal middle school intervention and alcohol misuse and alcohol use disorders among Mexican American high school students and implementation of universal middle school interventions to reach Latino communities.
