Patients' development across stages in long-term psychodynamic psychotherapy or psychoanalysis was studied in relation to various parameters of their therapists' training, or personal, therapies. The change variable was symptom distress, the General Symptom Index, according to the Symptom Checklist-90. A series of latent class regression analyses revealed that one class of therapists (16% of the sample) whose patients had the least change in treatment, and in fact had nonsignificant deterioration, was significantly overrepresented by psychotherapists with long psychoanalyses for their training therapies. Alternative interpretations of the findings are discussed. © 2006 Society for Psychotherapy Research.
