The effects of treatment and legal supervision on narcotics use and criminal activities were assessed by applying newly developed time-series methods that disentangle the long-term (permanent) and the short-term (temporary) effects of intervention.
A multivariate systems approach was used to characterize the dynamic interplay of several related behaviors at a group level over a long period of time.
Five variables-abstinence from narcotics use, daily narcotics use (or addiction), property crime methadone maintenance treatment, and legal supervision-were derived by aggregating information from over 600 narcotic addiction histories averaging 12 years in length.
Because of the long assessment period, age was also included as a control variable.
Overall, the system dynamics among the variables were characterized by long-term rather than short-term relationships.
