Is early outpatient satisfaction with substance use disorder care a predictor of early dropout? Results of the SUBUSQOL cohort.

Premature discontinuation of substance use disorder (SUD) treatment is a leading factor associated with poor outcomes. The aim of the study was to investigate factors associated with early dropout among individuals with SUD receiving outpatient care. In a prospective cohort of substance-dependent outpatients, we collected sociodemographic and clinical data, and participants completed questionnaires assessing health-related quality of life, states of anxiety and depression, and coping at baseline.
