Objective: Previous studies have shown that feedback-informed treatment can improve outcomes of psychological treatments. This randomized controlled effectiveness trial evaluated the effect of progress feedback on treatment duration, symptom reduction, and dropout in individual cognitive behavioral therapies (CBTs). A control condition where CBT was combined with low-intensive monitoring of progress was compared to an experimental condition where CBT was combined with a high-intensive form of feedback. Method: Data of 368 outpatients (57.9% female, mean age 41.4 years, SD = 12.2) in secondary care were analyzed using multilevel analyses. Treatment duration was assessed with the number of sessions clients received. Symptom reduction was measured with the Symptom Checklist Revised. Possible moderators of the effect of intensive progress feedback on outcome were explored. Results: Clients achieved the same amount of symptom reduction in significantly fewer sessions in the high-intensive feedback condition. Additionally, dropout was significantly lower in the high-intensive feedback condition. Post hoc analyses assessing clients' diagnoses as a possible moderator showed that clients with personality disorders (mainly Cluster C) achieved more symptom reduction in fewer sessions when high-intensity feedback was provided. Also, a high degree of implementation within the experimental condition was associated with fewer treatment sessions. Conclusion: In sum, the use of high-intensive client feedback reduced treatment duration and reduced dropout of CBT. Thus, feedback-informed CBTs seem to be a promising adaptation of conventional CBT.
