Attachment style and treatment completion among psychiatric inpatients with substance use disorders.

Background And Objectives: A strong dose-response relationship exists for psychosocial treatments for co-morbid substance abuse disorders; yet rates of attrition are exceedingly high for those seeking treatment in residential and hospital settings. This study examined patient characteristics, including attachment style as predictors of completing 42 contiguous days of inpatient dual-diagnosis treatment among patients with substance use disorders.

Methods: Baseline characteristics were assessed in 187 consecutively admitted patients with research diagnosis of substance use disorders.
