The use of client feedback, via self‐report measures of psychological functioning and working alliance, is an effective way to improve therapy outcomes. Despite this progress, there are many questions about the mechanisms of change for these systems. The current study employed a case study approach to examine the effectiveness of feedback informed treatment within a psychodynamic therapy. We examined the case based on therapy outcomes, alliance processes, and verbatim dialogue of in‐session exchanges. We also conducted a semistructured interview with the therapist to understand how she used and interpreted the feedback within her psychodynamic approach. The results demonstrated positive therapy outcomes and that feedback assisted with alliance formation, specifically decision making about therapeutic tasks and managing negative countertransference. The therapist reported that the feedback enhanced her ability to work in the here and now and to identify relational patterns. Implications for theory and practice are discussed.
