Additive effectiveness of mindfulness meditation to a school-based brief cognitive-behavioral alcohol intervention for adolescents.

This randomized controlled trial is the 1st study to evaluate the additive efficacy of mindfulness meditation to brief school-based universal cognitive behavior therapy (CBT + MM) for adolescent alcohol consumption. Previous studies have lacked strong controls for nonspecific effects, and treatment mechanisms remain unclear. The present study compared a CBT + MM condition to an active control CBT intervention with progressive muscle relaxation (CBT + PMR) for nonspecific effects and an assessment-only control (AoC). Cluster sampling was used to recruit Australian adolescents ( Multilevel modeling analyses revealed that both intervention conditions reduced the growth of alcohol consumption compared to the AoC ( There was no evidence of mindfulness-specific effects beyond existing effects of CBT within a brief universal school-based CBT intervention. Hypothesized mechanisms of change were largely unsupported. (PsycINFO Database Record (c) 2019 APA, all rights reserved).
