Predicting retention in a residential drug treatment alternative to prison program.

One hundred and fifty felony drug offenders diverted from prison to community-based, residential drug treatment alternative to prison program completed a comprehensive interview as part of a longitudinal study. Treatment completion predictors were sought examining intake data (demographics, family, social, employment, medical, psychological, criminal, sexual behavior, drug use and treatment histories). Logistic regression results found completers had more social conformity and close friends, and less need for employment counseling, felony drug convictions, drug dealing income, and unprotected sex than dropouts. Completers were also less likely to encounter recent problems with significant other, have a psychiatric history, experience gunshot or stabbing, and commenced heroin use at older ages than dropouts. However, completers reported higher alcohol use than counterparts. Further analyses explored subcategory models: "life choice" (substance use, criminal and sexual behavior), static (background and dispositional), and dynamic situational influences (employment, psychological state, recent and past encounters). Treatment implications considering findings are discussed.
