Changes in defense mechanisms have been shown in long-term psychodynamic treatment. The aim of this study was to examine the changes that occurred after brief cognitive-behavior group therapy in the defense style of panic disorder patients that had failed to respond to pharmacotherapy. Forty-seven patients participated in the study and severity of panic disorder was evaluated by Clinical Global Impression. Defense mechanisms were evaluated by the Defense Style Questionnaire. Patients decreased the use of maladaptive defenses after cognitive-behavior group therapy, and the change in immature defenses was maintained at 1-year follow-up evaluation (p = 0.022). These modifications were associated with reduction of symptoms (F = 0.359; p = 0.047). These findings are consistent with the hypothesis that defense styles are malleable in short-term treatment and are, at least partially, symptom-state dependent.
