Die Effekte psychoanalytisch orientierter und verhaltenstherapeutischer Langzeittherapien

This prospective study compares 31 patients in behavior long-term-therapy (with an average of 63 sessions) with 31 patients in psychoanalytically-oriented long-term-therapy (with an average of 185 sessions) in a naturalistic design. All patients passed a diagnostic interview (SKID) by an external interviewer. Only patients with depression and anxiety problems (Axis I of DSM III – R) were included in the study. Symptoms (SCL-90-R), interpersonal problems (IIP-D) and goals (GAS) were examined at the beginning, after 1 year, after 2.5 and 3.5 years. We found that the characteristics of patients, who choose – or were referred to – psychoanalytically oriented or behaviour long term therapy were different, even when their diagnosis were comparable, in a number of characteristics, such as education, access to psychotherapy (recommended by professionals versus patients introduce themselves), the taking of psychotropic medication, and the strain of symptoms. The results demonstrate how research comparing therapies using parallelized samples do not meet reality in every case: Even if psychoanalists and behavior therapists do treat equal disorders, – and they each do that very successfully, as we could prove – the patients differ in many ways. Effect sizes and clinically significant results about changes of the symptomatic and of interpersonal problems are presented that prove the efficacy of the treatments.
