Culturally enhancing a group-based motivational interviewing substance use prevention program for Latine youth

Group Motivational Interviewing for Teens (GMIT) has been effective in reducing youth substance use in diverse communities, yet more research is needed to determine its efficacy in reducing tobacco and alternative tobacco products (ATP) use among Latine adolescents. This study modified GMIT to include a focus on ATPs (GMIT-ATP). GMIT was also linguistically translated so it could be offered in English and Spanish, culturally enhanced, and parent sessions were added (GMIT-ATP + P).

The study's aims were to 1) Develop a model of how cultural context, family relationships, and adolescent tobacco-related skills/beliefs are associated with smoking and ATP use; 2) Examine the impact of the GMIT-ATP intervention on adolescent tobacco use; 3) Examine whether the GMIT-ATP + P intervention improves family/parenting factors associated with reduced adolescent tobacco use; 4) Examine whether GMIT-ATP + P is more effective than GMIT-ATP in improving adolescent tobacco use; 5) Explore whether essential components of our behavior change model mediate the impact on tobacco use, and 6) Explore whether cultural factors influence the impacts of our intervention. Latine adolescents (ages 10-16) and their parents/guardians were recruited throughout Virginia. Parents and adolescents completed three surveys: before and immediately after the program ends and at 3-months post-intervention. Families attended 3 GMIT-ATP or GMIT-ATP + P sessions.

Findings from this study will be disseminated in Latine communities and with providers working with Latine youth and can serve as a community-based model to reduce substance and tobacco use (e.g., ATP) in these Latine communities.
