Multistage path models of adolescent alcohol and drug use: a reanalysis
Simplex and nonsimplex models containing personality and perceived environmental variables as predictors of current use of alcohol, marijuana, and other drugs were compared in this reanalysis of a 1980 study by R. H. Potvin and C. Lee. Contrary to the results presented in the original study, the authors found that a nonsimplex pattern of relations among different forms of drug use allowed for a more adequate representation of the data than a simplex model for two of the three different age groups of adolescents sampled. Comformity-commitment and religiousness had consistent negative effects on drug use in each sample; parental support-affection and parental approval of friends tended to have small negative effects on drug use; and self-esteem and alienation were unrelated to drug use. In general it appears that a nonsimplex model of current drug use provides a more adequate representation of the data than does a simplex model and that religiousness and conformity-commitment are constraining influences on adolescent involvement in drug use.
