The participants of the study included all women in reproductive ages with a diagnosis of premenstrual syndrome who had referred to Shahid Beheshti University of Medical Sciences in during November 2020 to December 2021. Forty participants were selected via purposive sampling. Twenty participants were then assigned into each group. Experimental group participants received 8 transdiagnostic treatment sessions. To collect data, Pittsburgh Sleep Quality Index and Premenstrual Symptoms Screening Tool were employed and analyze the data was done by SPSS statistical software; and paired t-test, and repeated measures analysis. Results: The mean and standard deviation of participants' age were 30.90 ± 8.06 for experimental group and 33.25 ± 9.58 for control group. Based on the results of repeated measures analysis, there was a significant difference between experimental and control groups with respect to sleep quality and PMS. Moreover, according to the results of paired t-test, there was a significant difference between groups in post-test and follow-up phases with regard to sleep quality and PMS. Conclusion: Therefore, transdiagnostic treatment has significant effects on sleep quality and PMS.

This meta-analysis was aimed at evaluating the evidence related to the effectiveness of Internet-Based Cognitive-Behavioral Therapy (ICBT) in patients with social phobia. A systematic review of Randomized Controlled Trials (RCTs) with regard to the effectiveness of ICBT for patients with social phobia was sought across multiple databases. The outcome variable in clinical trials was decline in symptoms of social phobia. The measures used included LSAS, SPS, SP-12, BAI and SAD. Twenty clinical trials met the inclusion criteria (1211 patients overall). The results of the analysis revealed that the ICBT is more effective compared to other treatments or control conditions based on patients' evaluation. The results of the present meta-analysis provide preliminary evidence of the effectiveness of ICBT as a clinical method for social phobia and suggest that more RCTs are needed to compare ICBT with common treatments such as medication, neurological methods, and behavioral interventions.
