Data were analyzed using repeated measures analysis of variance. The results of the analysis showed that unified trans-diagnostic treatment led to a significant improvement in anxiety sensitivity, sleep quality, and emotion regulation in people suffering from post-traumatic stress disorder (P<0/01). The examination of the follow-up periods showed that there was no significant difference between the follow-up and post-test periods (P>0/01). Therefore, this shows the persistence of the treatment effect over time. From the above findings, it can be concluded that unified transdiagnostic treatment can be used as an effective approach to modify and improve the psychological problems of people with post-traumatic stress disorder.
