This study examined whether the significant intervention effects of the Communities That Care (CTC) prevention system on youth problem behaviors observed in a panel of eighth-grade students (Hawkins et al. Archives of Pediatrics and Adolescent Medicine 163:789-798 2009) were mediated by community-level prevention system constructs posited in the CTC theory of change. Potential prevention system constructs included the community's degree of (a) adoption of a science-based approach to prevention, (b) collaboration on prevention activities, (c) support for prevention, and (d) norms against adolescent drug use as reported by key community leaders in 24 communities. Higher levels of community adoption of a science-based approach to prevention and support for prevention in 2004 predicted significantly lower levels of youth problem behaviors in 2007, and higher levels of community norms against adolescent drug use predicted lower levels of youth drug use in 2007. Effects of the CTC intervention on youth problem behaviors by the end of eighth grade were mediated fully by community adoption of a science-based approach to prevention. No other significant mediated effects were found. Results support CTC's theory of change that encourages communities to adopt a science-based approach to prevention as a primary mechanism for improving youth outcomes.

BACKGROUND: Behavioral disinhibition (externalizing/impulsivity) and behavioral inhibition (internalizing/anxiety) may contribute to the development of alcohol abuse and dependence. But tests of person-by-environment interactions in predicting alcohol use disorders are needed. This study examined the extent to which interactions between behavioral disinhibition, behavioral inhibition and family management during adolescence predict alcohol abuse and alcohol dependence at age 27.

METHODS: This study used longitudinal data from a community sample of 808 men and women interviewed from ages 10 to 27 in the Seattle Social Development Project. Zero-order correlations followed by a series of nested regressions examined the relationships between individual characteristics (behavioral disinhibition and behavioral inhibition/anxiety) and environment (good vs. poor family management practices during adolescence) in predicting alcohol abuse and dependence criterion counts at age 27.

RESULTS: Behavioral disinhibition and poor family management predicted increased likelihood of both alcohol abuse and alcohol dependence at age 27. Behavioral inhibition/anxiety was unrelated to both outcomes. Youths high in behavioral disinhibition were at increased risk for later alcohol abuse and dependence only in consistently poorly managed family environments. In consistently well-managed families, high levels of behavioral disinhibition did not increase risk for later alcohol abuse or dependence.

CONCLUSIONS: Behavioral disinhibition increases risk for alcohol abuse and dependence in early adulthood only for individuals who experience poor family management during adolescence. Interventions seeking to reduce environmental risks by strengthening consistent positive family management practices may prevent later alcohol abuse and dependence among individuals at risk due to behavioral disinhibition.
