The effect of process and outcome feedback in highly distressed outpatients: A randomized controlled trial

Objectives: Although process and outcome feedback is considered to be facilitative of psychotherapeutic processes, recent studies have suggested that such feedback may not produce the same effect when applied to highly distressed patients. This study examined the effect of process and outcome feedback in highly distressed patients treated in a public mental health center in Israel. Method: Patients (n = 197) were randomly allocated to receive feedback, or to treatment as usual. Therapists in the feedback condition received weekly reports, whereas therapists in the control group received no feedback. After attrition from study and treatment, a total of 123 cases were analyzed. Results: Feedback had no significant effect on either symptom reduction or on well-being. However, patients in the feedback group showed higher gains in alliance as compared to the treatment as usual group. Conclusion: Process and outcome feedback might have a potential beneficial effect of improving alliance for patients with severe symptomatology, with whom the establishment of an alliance can be challenging. The current findings also stress the need to continue to study the effect of feedback on therapy outcomes in diverse clinical settings. Limitations and directions for future research are discussed.
