Structural equation modeling (SEM) was used to examine the utility of locus of control (LOC) for predicting adolescent substance use. As part of a larger three-wave cohort-sequential study (1983-1989), 155 secondary school-based adolescents completed questionnaires on substance use, personality characteristics, family/peer influences, and health behaviors. Latent variable indicators were developed from the Nowicki-Strickland Personal Reaction Survey and substance use survey items. LOC was a weak predictor of substance use. In two instances were relationships significant: (a) 7th grade LOC predicted 11th grade alcohol use; and, (b) 9th grade LOC correlated with 11th grade cannabis use. Small samples precluded analysis of gender and social class effects. SEM with panel data offers a methodological approach for examining the explanatory capability of LOC.
