One hundred and fifty felony drug offenders diverted from prison to communi
ty-based, residential drug treatment alternative to prison program complete
d a comprehensive interview as part of a longitudinal study. Treatment comp
letion 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 pro
blems with significant other, have a psychiatric history, experience gunsho
t or stabbing, and commenced heroin use at older ages than dropouts. Howeve
r, completers reported higher alcohol use than counterparts. Further analys
es explored subcategory models: "life choice" (substance use, criminal and
sexual behavior), static (background and dispositional), and dynamic situat
ional influences (employ ment. psychological state, recent and past encount
ers). Treatment implications considering findings are discussed. (C) 2000 E
