Person-Environment Fit, Substance Use Attitudes, and Early Adolescent Substance Use.

BACKGROUND

Adolescent substance use is a national health concern. While the literature is clear on the prevalence of substance use during the adolescent developmental period, a dearth of literature is available on the developmental contexts, particularly the influence of school factors, in which substance use occurs.

OBJECTIVES

This study examined the intermediary role of substance use attitudes on the relationship between school racial composition and alcohol and marijuana use in a sample of sixth to eighth graders.

METHODS

The sample consisted of 4228 middle school students (89% White; 53% female) in the Midwest. A moderated mediation analysis was conducted on the relationship between school racial composition, substance use attitudes, and substance use, with race as the moderator.

RESULTS

Results indicated a significant relationship between the percentage of White or Black students in a school and alcohol or marijuana use and that this relationship was mediated by substance use attitudes. These relationships did not differ significantly by student race. Conclusions/

Importance

Preliminary findings indicate the importance of considering school racial composition as a systems level risk or promotive factor for attitudes toward substance use as well as substance use outcomes.
