Studying the effectiveness of the transdiagnostic unified protocol on this group of patients who may have undergone several postearthquake psychological disorders for years could deliver promising results.<\/jats:p>\n <\/jats:sec>\n \n MATERIALS AND METHODS:<\/jats:title>\n This quasiexperimental study included pretest, post-test, and a 2-month follow-up period, with a control group. The population included all patients with post-traumatic stress disorder in Sarpol-e Zahab city. A sample of 33 people suffering from post-traumatic stress disorder was selected through available sampling and randomly assigned to two experimental (11 people) and control groups (22 people). All participants completed Mississippi Scale for Combat-Related PTSD (M-PTSD) for DSM-III, Beck Depression Inventory (BDI-II), and The Hamilton Anxiety Rating Scale (HARS) in the pretest, post-test, and follow-up (two-month) assessments. The data were analyzed using SPSS-23 one-way analysis of covariance.<\/jats:p>\n <\/jats:sec>\n \n RESULTS:<\/jats:title>\n \n Compared to the control group, the patients in the transdiagnostic unified protocol group experienced significant reductions in PTSD symptoms and comorbid depressive and anxiety symptoms (\n P<\/jats:italic>\n = 0.01). Furthermore, the effect size in the experimental group was higher than medium.\n <\/jats:p>\n <\/jats:sec>\n \n CONCLUSION:<\/jats:title>\n According to the findings, the unified protocol for transdiagnostic treatment had propitious results in alleviating the symptoms of PTSD and comorbid disorders emerging after Sarpol-e Zahab earthquake. Therefore, this intervention could be a potential substitute for the TAU provided by the Ministry of Health.<\/jats:p>\n
