A relatively stable general involvement in deviance accounted for virtually all association between different types of deviance, but the stability of each behavior could only be explained by equally important and stable specific influences. Thus, theories that treat different deviant behaviors as alternative manifestations of a single general tendency can account for some, but far from all, of the meaningful variance in these behaviors. The only significant influence of one type of deviance on another was that of marijuana use on later use of other illicit drugs. The causal model also revealed interpretable shifts in the associations among these behaviors over the 4 years following high school. (Author abstract)
