[Psychodynamic short-term group treatment for social phobia: description of the treatment concept and a case study].

Based upon the concept of supportive-expressive therapy (SET), we developed a psychodynamic group treatment manual for social phobia, with a special focus on the patients' individual core conflictual relationship themes, their universality, as well as interventions promoting group processes and therapeutic factors of group therapy. We introduce the new concept and report results of a pilot case study (N=8). Analyses revealed a pre-post-treatment effect size of g=0.64 (95% CI [0.29; 1.00]) on the primary outcome measure, the Liebowitz Social Anxiety Scale (LSAS). Furthermore we obtained positive evidence with regard to acceptance, safety and feasibility of the psychodynamic group therapy concept for social phobia. Subsequent proof-of-concept studies are required to foster treatment development and to proof the replicability of results.
