[Effectiveness of Psychoanalytic Psychotherapy for Children and Adolescents with Severe Anxiety Psychopathology in a Naturalistic Treatment Setting].

Effectiveness of Psychoanalytic Psychotherapy for Children and Adolescents with Severe Anxiety Psychopathology in a Naturalistic Treatment Setting The aim of the study was to evaluate naturalistic out-patient psychoanalytic youth psychotherapy in Germany. The study was a partly controlled effectiveness trial. While the first treatment interval (25 sessions, 6.13 months) was compared with a wait-list control group (5 supportive sessions, 2.94 months), the effects of long-term psychoanalytical treatment were analyzed using a time-series design. 86 children and adolescents (aged 4 to 21 years) and their parents who entered psychoanalytic therapy in private practices participated in this study. The wait-list control group comprised 35 patients. Questionnaires were administered at the beginning and the end of treatment, as well as 6 and 12 month follow-up (FU). Patients received on average 94.04 therapy sessions (range 8 to 300) over 25.70 months. Data analyses were carried out with multilevel mixed linear models on the intention-to-treat (ITT) sample. The patients in the intervention group reported moderate symptom improvements at the end of therapy (d = .57), these effects are stable at the 1-year follow-up and increase from the patient perspective (d = .80). When comparing the first therapy interval with the (minimal treatment) wait-list control group, both groups improved significantly with small effect sizes and no significant group differences. The results suggest that long-term psychoanalytic therapy is successful in alleviating anxiety pathology and improving quality of life for youth with anxiety disorders, and that improvements remain stable across a 1-year follow-up period.
