PIRE Publication - Prevention of Underage Drinking on California Indian Reservations Using Individual- and Community-Level Approaches

Objectives: To evaluate combined individual- and community-level interventions to reduce underage drinking by American Indian/Alaska Native (AI/AN) youths on rural California Indian reservations. Methods: Individual-level interventions included brief motivational interviewing and psychoeducation for Tribal youths. Community-level interventions included community mobilization and awareness activities, as well as restricting alcohol sales to minors. To test effects, we compared 7 waves of California Healthy Kids Survey data (2002-2015) for 9th and 11th-grade AI/AN and non-AI/AN students in intervention area schools with California AI/ANstudents outside the intervention area (n = 617, n = 33469, and n = 976, respectively). Results: Pre- to postintervention mean past 30-day drinking frequency declined among current drinkers in the intervention group (8.4-6.3 days) relative to comparison groups. Similarly, heavy episodic drinking frequency among current drinkers declined in the intervention group (7.0-4.8 days) versus the comparison groups. Conclusions: This study documented significant, sustained past 30-day drinking or heavy episodic drinking frequency reductions among AI/AN 9th- and 11th-grade current drinkers in rural California Indian reservation communities exposed to multilevel interventions. Public Health Implications. Multilevel community-partnered interventions can effectively reduce underage alcohol use in this population.
