Trauma-focused psychotherapies are increasingly offered in community-based mental health centers, but little is known about treatment dropout in these settings. The current study explored dropout at different stages of treatment in a treatment-seeking sample of 1,186 adults who experienced interpersonal violence and were offered trauma-focused and non–trauma-focused therapies. A total of 31.6% of participants dropped out before treatment initiation, 28.0% dropped out after treatment initiation and completed a mean of 4.02 (SD = 2.41) sessions, and 40.4% completed a full course of PTSD treatment. Being unemployed, p < .001, and scoring lower on measures of environment factors, p = .045, were significant predictors of pretreatment dropout. Being female, p < .001; Latinx, p = .032; and scoring higher on a measure of social relationships, p = .024, were independent predictors of postinitiation dropout. Individuals who completed nine sessions of treatment displayed significantly lower levels of posttraumatic stress disorder, depression, and anxiety symptoms. The present study provides preliminary evidence that survivors of interpersonal violence who seek therapy tend to drop out early during treatment, and most who complete treatment attain symptom reduction.
