Therapists' professional and personal characteristics as predictors of outcome in long-term psychodynamic psychotherapy and psychoanalysis.
BACKGROUND
Whether long-term psychodynamic therapy (LPP) and psychoanalysis (PA) differ from each other and require different therapist qualities has been debated extensively, but rarely investigated empirically.


METHODS
In a quasi-experimental design, LPP was provided for 128 and PA for 41 outpatients, aged 20-46 years and suffering from mood or anxiety disorder, with a 5-year follow-up from start of treatment. Therapies were provided by 58 experienced therapists. Therapist characteristics, measured pre-treatment, were assessed with the Development of Psychotherapists Common Core Questionnaire (DPCCQ). General psychiatric symptoms were assessed as the main outcome measure at baseline and yearly after start of treatment with the Symptom Check List, Global Severity Index (SCL-90-GSI).


RESULTS
Professionally less affirming and personally more forceful and less aloof therapists predicted less symptoms in PA than in LPP at the end of the follow-up. A faster symptom reduction in LPP was predicted by a more moderate relational style and work experiences of both skillfulness and difficulties, indicating differences between PA and LPP in the therapy process.


CONCLUSIONS
Results challenge the benefit of a classically "neutral" psychoanalyst in PA. They also indicate closer examinations of therapy processes within and between the two treatments, which may benefit training and supervision of therapists.
