BackgroundAlthough considerable research has tested evidence-based practices in clinical trials, research is needed on the use of trauma-focused treatments by victims of crime and violence in naturalistic settings. This study investigated four trauma-focused treatments, prolonged exposure therapy (PE), cognitive behavioral therapy (CBT), eclectic therapy, and person-centered therapy (PCT), and assessed treatment dropout and symptom improvement over five assessment time-points. MethodsDescriptive comparisons and pattern mixture multigroup growth models were used to assess differences between treatments on time in treatment, rate of dropout, and improvement in posttraumatic stress (PTSD) and depression symptoms in an outpatient sample of 526 clients seeking routine clinical care. ResultsPCT was significantly associated with the highest number of therapy sessions completed and the lowest rate of dropout (41.75%) compared to CBT and eclectic treatments. All treatment groups reported PTSD symptom improvement with no significant differences based on therapy type. For depression, the rate of improvement for clients in PCT who dropped out of treatment after session 3 was significantly steeper than the rate of improvement for clients in eclectic treatment who dropped out of treatment after session 3. Clients who stayed in treatment longer generally had larger decreases in symptoms compared to those who dropped out earlier. LimitationsThe small sample size in each of the treatment groups may have limited power to detect change. ConclusionsSeveral trauma-focused treatments offered in a community-based setting may result in significant symptomatic improvement.
