Summary
The current study aims to test the efficacy of a family communication-based, novel, adaptable, and resource-efficient substance misuse preventive intervention for parents/guardians of pre/early adolescents (grades 5-7). The short-term goal of this study is to increase the quality time that parents spend with their children through eating meals together, and in so doing, talking about the harms associated with substance use (intermediate endpoint), which will in turn, lead to the long-term goal of preventing the initiation and misuse of substances among their children as they enter adolescence.
