Are Risk and Protective Factors for Substance Use Consistent across Historical Time? National Data from the High School Classes of 1976 through 1997

Investigated whether correlates of substance use changed across historical time. A high degree of consistency was found across historical time in predictors of past month cigarette or alcohol use and past year marijuana or cocaine use. Some predictors were consistently linked to substance use. Consistency of other predictors was contingent upon time period, substance, and level of use. (BF)
