In this study, we developed and tested a common factors feedback (CFF) system. The CFF system was designed to provide ongoing feedback to clients and therapists about client ratings of three common factors: (a) outcome expectations, (b) empathy, and (c) the therapeutic alliance. We evaluated the CFF system using randomized, clinical trial (RCT) methodology. Participants: Clients were 79 undergraduates who reported mild, moderate, or severe depressive symptoms at screening and pretreatment assessments. These clients were randomized to either: (a) treatment as usual (TAU) or (b) treatment as usual plus the CFF system (TAU + CFF). Both conditions entailed 5 weekly sessions of evidence-based therapy delivered by doctoral students in clinical psychology. Clients completed measures of common factors (i.e., outcome expectations, empathy, therapeutic alliance) and outcome at each session. Clients and therapists in TAU + CFF received feedback on client ratings of common factors at the beginning of Sessions 2 through 5. When surveyed, clients and therapists indicated that that they were satisfied with the CFF system and found it useful. Multilevel modeling revealed that TAU + CFF clients reported larger gains in perceived empathy and alliance over the course of treatment compared with TAU clients. No between-groups effects were found for outcome expectations or treatment outcome. These results imply that our CFF system was well received and has the potential to improve therapy process for clients with depressive symptoms.
