Completing substance abuse treatment in child welfare: the role of co-occurring problems and primary drug of choice.

A significant number of substance-abusing parents in the child welfare system do not complete substance abuse treatments. Consequently, their children experience longer stays in substitute care settings, and the risk of the termination of parental rights is increased. This study identifies and determines the specific factors that explain the completion of substance abuse treatment for substance-abusing caregivers in child welfare. The sample includes 871 caregivers enrolled in the Illinois Alcohol and Other Drug Abuse waiver demonstration. Approximately 22% of these caregivers successfully completed all required levels of substance abuse treatment. The multivariate models indicate that age, employment status, and legal involvement were significantly associated with the likelihood of completing substance abuse treatment. Heroin users were significantly less likely to complete treatment as compared with alcohol, cocaine, and marijuana users. The findings are discussed in terms of policy and practice implications for public child welfare systems.
