Influence of Risk and Protective Factors on Substance Use Outcomes Across Developmental Periods: A Comparison of Youth and Young Adults Read More:



Data were collected from samples of youth (ages 11–18; N = 38,268) and young 10 adults (ages 18–24; N = 602) across 30 Tennessee counties using surveys and telephone interviews conducted in 2006–2008.

Data were analyzed using hierarchical nonlinear modeling to determine: (1) which risk and protective factors predicted alcohol and marijuana use, and (2) whether predictors differed as a function of developmental period.

Findings provide preliminary evidence that prevention efforts need to take into consideration the changing environment and related influences as youth age, especially as they move from a more protected community environment to one where they live somewhat independently. Implications and limitations are discussed.
