Predictors of overall and on-the-job substance use among young workers.

Predictors of overall and on-the-job substance (alcohol and marijuana) use were studied in a sample of young workers. The 18 predictors represent 6 general domains of risk factors: demographic, personality, substance use outcome expectancies, workplace substance availability, workplace social control, and work stressors. Data were obtained from a sample of 319 individuals ages 16 to 19. Hierarchical tobit regression analyses revealed that 5 of the 6 domains of risk factors were related to employee substance use. Similarities and differences were found in the predictors of overall and on-the-job substance use and in the predictors of alcohol and marijuana use.
