OBJECTIVE: This report contains preliminary data from an open trial of brief psychodynamic psychotherapy for panic disorder. METHOD: Fourteen patients with primary DSM-IV panic disorder completed a 24-session, twice-weekly course of psychodynamic psychotherapy. Other psychiatric treatment was not permitted throughout the 12-week treatment period and the 6-month follow-up. Symptoms were assessed at baseline, treatment termination, and 6-month posttermination follow-up (40 weeks). RESULTS: Statistically significant, clinically meaningful improvements appeared in panic, depression, anxiety, and functional impairment both at treatment termination and at 6-month follow-up. CONCLUSIONS: Psychodynamic monotherapy can be used successfully to retain and treat patients with panic disorder. Psychodynamic interventions warrant further study for patients with panic disorder.
