The Alcohol and Other Drug survey (adapted from D. Thombs, 1999) was administered to 235 undergraduates at a southeastern university to assess the influence that gender-specific normative perceptions have on 2 substance abuse patterns. Multiple regression analyses confirmed that gender-specific normative beliefs accounted for variance in alcohol use intensity and frequency of marijuana use beyond the variance accounted for by sociodemographic variables. Implications for college counselors are discussed. (Contains 2 tables.)
