The American Psychological Association task force on empirically supported therapy relationships defined countertransference (CT) management (i.e., awareness of CT) as a “promising” element in psychotherapy research. The present study aimed to examine how changes in therapist CT and awareness of CT relate to therapy process and outcome. The data analysis was based on 41 treatments and used the core conflictual relationship theme to measure CT. We found that changes in therapists’ Wishes from the relationship with the patient at the beginning of therapy were related to patients’ working alliance and symptom changes at the end of treatment. Changes in therapist awareness of CT moderated the relationship between therapists’ wishes from the therapy and patients’ symptom changes during therapy. Last, we present a case study and discuss how awareness of CT can help the therapist handle the challenges that arise from it.
