Examining a Partial Biopsychosocial Model for Monthly Alcohol, Tobacco, and Marijuana Use Among Adolescents

Alcohol, tobacco, and marijuana are commonly used substances among adolescents. In the context of the Biopsychosocial Model (BPSM), this study investigated the relationships between psychological and normative factors associated with adolescent alcohol, tobacco, and marijuana use. Data were analyzed from 1053 middle and high school students. Structural equation modeling was used to examine the relationships between BPSM constructs. Results indicate that latent constructs of the BPSM are significant antecedent factors to alcohol, tobacco, and marijuana use; however, the relationships between study constructs were inconsistent with those theorized by BPSM. Findings support the importance of theory testing for complex models applied to new topics and new populations.
