[A multicenter study of expenditure and success in psychodynamic therapy of eating disorders. Study design and initial results].
Evaluation of psychodynamically oriented treatment of anorectic and bulimic patients, taking into account both quality and cost of therapist ("How much therapy is applied to which patients for a successful treatment?"). Criteria for indication of the kind of therapy and of amount of therapy ("dosage") are provided.


METHODS
Prospective naturalistic longitudinal study (comparable to phase IV of effectiveness studies on pharmaceuticals) including 2.5 year follow-up. Consecutive sample (Anorexia nervosa and bulimia nervosa, DSM-III-R). Multidimensional outcome measures including self-rating and expert-ratings. Operationalisation of outcome is layered. Differentiated measurement of amount of therapy and treatment elements. Survival analysis, logistic regression.


RESULTS
1171 completely documented treatment episodes of 43 institutions (30.3% Anorexia nervosa, 55.3% bulimia nervosa, 14.4% double diagnoses). Patients are chronically ill (M = 7.6 years; SD = 6.3 years) and at the beginning of (mostly inpatient) treatment of the index episode 25.5 years of age (SD = 6.0 years). Therapies last appr. 11 weeks (median) and encompass a broad range of therapy measures.


CONCLUSIONS
Study conduction as well as data collection and analysis of this worldwide largest study on treatment of eating disorders is discussed by presenting preliminary results.
