The purpose of this study is to investigate the relationship between general mental health, posttraumatic stress, and counselor efficacy of psychotherapists who became suicide survivors due to client suicide. For this purpose, 20 psychotherapists and 20 general psychotherapists with suicide survivor experience were surveyed using General Health Questionnaire in the Korean General Adult Population, Korean Version of Impact of Event Scale, and Counselor Activity Self-efficacy Scale. A comparison of the two groups showed that the suicide survivor psychotherapist experienced depression and anxiety, social dysfunction, awakening, avoidance, invasion, sleep disturbance and dissociation symptoms. In addition, it showed relatively low efficacy compared to general therapist group in listening skills to understand the message of the client, reflection of emotion, open question, re-statement, the relationship between the client. And the client was not felt efficacy in the difficulty of counseling dealing with the pain. As a result of analyzing the correlation between the General Health Questionnaire in the Korean General Adult Population of the suicide survivor therapist group, the Korean Version of Impact of Event Scale, and the sub-factors of the self, the more experience of depression and anxiety, the lower the efficacy as a counselor, and the more experienced the symptoms of PTSD, the more difficult it is to exert a sense of efficacy as a counselor. This suggests that psychological help should be provided for post-treatment intervention for suicide-survivor psychotherapist, and specific skills and education related to counseling should be combined.
