This study aimed to compare the effect of cognitive-behavioral therapy (CBT), and acceptance and commitment therapy (AT) on resilience, happiness, and hope of veterans with psychopathy. The present study was applied in terms of purpose, a pre-test, post-test, and follow-up research in terms of method, and a quasi-experimental design in terms of nature. The results showed a difference between the mean scores of resilience, happiness, and hope in the three acceptance and commitment therapy, cognitive-behavioral therapy, and control groups within pre-test, post-test, and follow-up steps. There was a difference between the effects of ACT and CBT on resilience, happiness, and hope of veterans with psychopathy living in Dezful. Moreover, ACT performed better rather than CBT in terms of resilience, happiness, and hope rate among veterans with psychopathy living in Dezful, Iran.
