The present study examined effectiveness of group Acceptance and Commitment Therapy (G-ACT) for psychiatric outpatients. The program of G-ACT was consisted of 8 sessions including exercises and homework about acceptance skills, mindfulness skills, and a modification of behavior. At pre-treatment, post-treatment and 1-month later follow-up period, all patients (N=11) completely STAI, the factor of Reframing from Catastrophic Thinking in the Cognitive Control Scale, and AAQ-II. The results revealed that the post treatment scores and follow-up scores on the all measurement instruments were significantly improved and the each effect sizes were medium or large. These results show that the G-ACT is effective for patients who have anxiety symptoms. The present study might provide the preliminary evidence about the application of G-ACT for patients who have anxiety symptoms.
