Abstract
The purpose of this research was (a) to assess differences in retention patterns and discharge status across three program settings; and (b) to examine selected pretreatment characteristics that might help predict treatment retention, which was operationalized as length of time in treatment. Three groups of pretreatment characteristics were examined. They included demographic factors, drug use and treatment history, and psychological status and symptomology. Clients in the intensive day treatment program tended to stay longer and were more likely to successfully complete the program than either clients in the outpatient or the traditional residential programs. In general, pretreatment client characteristics were not helpful in predicting length of time in treatment regardless of program type. Few pretreatment characteristics were related to retention within programs and significant predictors differed across treatment settings.
