Predictors of completing treatment and achieving abstinence during inpatient dual diagnosis treatment

Abstract

A diagnosis of alcohol dependence was associated with abstinence during community linkage. Discussion: Dual diagnosis patients with severe substance dependence, as well as patients with elevated thought disturbance and anxiety...
