Sharp increases in substance use rates among youth in Mexico are a major concern, both in México and in the US. Although substance abuse prevention is a national priority, Mexico has few school-based universal prevention programs that are culturally grounded, empirically tested, and shown to be efficacious. Along with our partners in Mexico, GCAHR addressed this gap by culturally adapting, implementing, and testing a Spanish-language version of the keepin' it REAL (kiREAL) prevention program in Mexico's three largest cities. Translated to Spanish the adapted prevention program is entitled Mantente REAL (MREAL). The acronym REAL – Refuse, Explain, Avoid, and Leave – represents four strategies commonly used by youth who do not use substances: refuse substance offers with a direct no, explain why you decline, avoid substance offer situations, or leave them.

Frequency and amount of use of alcohol, tobacco, marijuana and other drugs; non-permissive attitudes towards drug use; violence perpetration and victimization.

In Phase I of the project, our bi-national research team, including the original kiR curriculum designers, collaborated to ensure cultural applicability in Mexico and fidelity to core elements of kiREAL. The cultural adaptation of MREAL addressed neighborhood, school and family violence that often accompanies substance use offers for Mexican adolescents, such as threats of violence and intimidation. The adaptations represented gender-specific scenarios where Mexican adolescents confront drug offers, people offering substances aggressively, alternatives to responding in kind in an angry or violent way, and the ability to assess and leave situations when threatened. In Phase 2, we tested the efficacy of the culturally adapted MREAL, relative to the original version of kiREAL and to a control condition, in a randomized controlled trial with 5,523 7th grade students in 36 public middle schools.

The adapted MREAL version for Mexico showed numerous desired outcomes in areas deliberately targeted in the cultural adaptation. Compared to students receiving the unadapted version of kiREAL and to students in control schools, MREAL students had relatively more desirable outcomes in recent use of alcohol, cigarettes, “hard drugs”, heavy episodic drinking and intoxication. MREAL students reported relatively less violence victimization and perpetration of bullying, and relatively more use of three of the intervention’s REAL drug resistance strategies (Explain, Avoid, Leave).
