Randomized Controlled Trial
Effects of a Community-Level Intervention on Alcohol-Related Motor Vehicle Crashes in California Cities: A Randomized Trial.
This trial assesses the effects of a community-level alcohol prevention intervention in California on alcohol-related motor vehicle crashes. ⋯ Enhanced alcohol enforcement operations involving both community health and law enforcement agencies can help to reduce alcohol-impaired driving and related consequences among young people. Including measures of intervention dosage raises interesting questions about the understanding of the impact of the community intervention. Future studies should continue to further develop implementation strategies that may more effectively and efficiently reduce community alcohol-related harm.

Randomized Controlled Trial
Randomized Trial to Reduce Risky Sexual Behavior Among Justice-Involved Adolescents.
Justice-involved adolescents are at high risk for sexually transmitted infections; one primary reason is co-occurring substance use. This study investigates the additive benefit of including alcohol and cannabis use content in a theory-based sexual risk reduction intervention, delivered using group-based motivational enhancement therapy. ⋯ All 3 interventions were associated with decreased sexual risk up to 1 year later, suggesting that the intervention modality (motivational enhancement therapy) may resonate with this population beyond the specific substance use content. This single-session manualized intervention can be readily disseminated to juvenile justice settings.
