Predictors of completion of an adolescent residential alcohol and other drug withdrawal program

Abstract

This study extends the limited research on predictors of completion of adolescent residential drug and alcohol program. A Queensland, Australia, five-bed state-wide voluntary adolescent drug and alcohol withdrawal service collected routine clinical pre-entry data over a period of 9 years (2000–2009) on 524 subjects. Potential predictors of program completion included socio-demographic, family functioning, past mental health history, mental health problems on admission, and patterns of drug use variables. The chi-square analysis identified significant predictors with subsequent multivariate logistic regression modeling. Given the loss of data, additional multiple imputation logistic regression analysis was utilized. Initial predictors were aged 17 and over; a past history of psychiatric treatment or violence or assault; mental health problems identified on entry; absence of current alcohol use or ecstasy use. After regression and multiple imputation modeling, predictors were a history of psychiatric treatment and of violence/assault. A history of co-morbidity rather than traditional markers of good outcomes such as sex, ethnic background, income support, and housing support predicted program retention. The study reinforces the important role of non-substance psychiatry co-morbidity in the treatment of substance use disorder.
