Problem Behavior Theory, consisting of personality, perceived environment, and behavior systems, was employed to account for variation in marijuana use among junior high, senior high, and college students, both male and female. The research design enabled both cross-sectional comparisons between nonusers and users on variables in each of the systems and longitudinal comparisons between those who shifted to user status over a 1-year interval and those who remained nonusers. Data revealed a similar pattern of personality, environment, and behavior differences between all nonuser and user groups, suggesting a pervasive social-psychological constancy. The same variables were also predictive of the shift from nonuse to use over time among the high school students but not the college students. |
