Relapse rates for psychosocial substance use disorder (SUD) treatments are high, and dropout is a robust predictor of relapse. This study aimed to estimate average dropout rates of in-person psychosocial substance use disorder (SUD) treatments and to assess predictors of dropout. The researchers examined data from studies anywhere in the world that analyzed substance use disorder treatments from 1965 to 2016.

Researchers collaborated on this study include Dr. Peter S. Hendricks and Dr. Sara Lappan of the University of Alabama at Birmingham, and Dr. Andrew W. Brown, Indiana University Bloomington.

On average, approximately 30 percent of participants drop out of in-person psychosocial SUD treatment studies, but there is wide variability. Drop-out rates vary with the treated population, the substance being targeted, and the characteristics of the treatment.
