Understanding routine outcome monitoring and clinical feedback in context: Introduction to the special section

The practice of routine outcome monitoring and providing clinical feedback has been widely studied within psychotherapy. Nevertheless, there are many outstanding questions regarding this practice. Is it an evidence-based adjunct to ongoing psychotherapies, or an ineffective complication of treatment? If it is effective, through what mechanism(s) does it act? Is it effective with all patient populations, treatment types, and service delivery mechanisms, or does its impact vary across context? What choices in the implementation process affect the utility of patient-reported data feedback on psychotherapy outcomes? The studies in this special section explore these questions using a wide variety of methods and significantly expand the reach of studies on feedback. Together, these studies represent a snapshot of a maturing field of study: Initial discoveries are developed into more robust theories and applied in a wider range of contexts, while the limits of that theory are tested. They also signal directions for future clinical and research work that may improve patient care in psychosocial interventions into the future.
