[Does Personality Organization Influence Day Clinic Treatment Success? Results of a Longitudinal Study]. / Beeinflusst das Strukturniveau den Erfolg tagesklinischer Behandlung? Ergebnisse einer Längsschnittuntersuchung.

We conducted an exploratory questionnaire-based study (n=63) to assess the importance of personality organization for therapy success in a day treatment setting. Patients completed self-report measures at the beginning and end of treatment spanning 4-6 week capturing impairments in personality organization (IPO-16), acute symptom severity (SCL-90-R, BDI-2), personality disorders (ADP-IV), and traumatic experiences in childhood and adolescence (CTQ). We observed strong associations between impairments in personality organization, personality pathology, traumatic experiences, and acute symptom severity. Impairments in personality organization did not change during treatment. In contrast to other studies, an influence of personality organization on treatment success could not be demonstrated. The importance of personality organization for therapy planning should be studied further.
