ABLE 2 (COMPLETED)

Adolescent Behaviors & Lifestyle Behaviors 2 (Marijuana) was a 2-year randomized controlled trial funded by National Institute on Drug Abuse (NIDA; 1R01DA025640-01A1). ABLE 2 was designed to develop and test a school-based, brief motivational interviewing intervention for marijuana using, Hispanic/Latinx 10th and 11th grade students. The ethically/racially diverse sample, implementation with a non-treatment seeking population, and examination of putative mechanisms of change contributed to the significance of this RCT. The study focused on examining the efficacy of brief motivational intervention for reducing marijuana use and marijuana-related negative consequences among minority adolescent marijuana users. Results indicated that the majority of participants in the treatment conditions showed decrease in marijuana use and dependence.
