Quality measurement in psychodynamic psychotherapy: Diagnosis-specific courses, the influence of different informants, and their view of moderators of change Abstract. This study uses a naturalistic design to assess the course and effectiveness of long-term psychodynamic therapies from the perspective of adolescent patients and their mothers. It looks at the context of different moderators of change, including the characteristics of the patient, the therapist, and the therapy. Assessments of the internalizing, externalizing, and overall symptom burden using the Youth Self Report (YSR) and the Child Behavior Checklist (CBCL) were collected on 161 patients and their mothers at three timepoints - the beginning, middle, and end of therapy. The assessments of both informants showed a decrease in symptoms over the course of therapy with similar effect sizes (η² = .25 for the patients, η² = .31 for their mothers). The adolescents differentiated more between the diagnosis groups, reported higher symptom intensities at the beginning, and saw fewer changes in the second half of the therapy than their mothers. Psychodynamic long-term therapy was particularly effective for internalizing disorders according to both parents and patients. Both informants differed, however, in their evaluation of short-term therapy. An examination of the moderators of change in the mothers' evaluation (difference value of the total symptom burden between the beginning and end) showed that the therapist and therapy characteristics predicted change, whereas for adolescents, the patient characteristics have the greatest influence.
