The aim of the present study was to determine the clinical and differential validity of Social Responsiveness Scale-Second Edition (SRS-2) and Social Communication Questionnaire (SCQ) in a group of children and adolescents with autism spectrum disorder compared to a normal developmental group. \u0000Method: The study was conducted in Roozbeh Hospital involving 52 children with ASD and 53 typically developing (TD) children, aged between 4-12 years. Their parents completed the SRS-2 and SCQ. These children were also interviewed using the Childhood Autism Rating Scale, 2nd Edition (CARS-2) and Asperger Syndrome Diagnostic Scale (ASDS). After completion, the results were analyzed using the SPSS Version 18 software and a significant level of 0.05. \u0000Results: The average age of children in the autism group was 7.5 ± 2.7 years, while in the typically developing (TD) children group, it was 7.7 ± 2.3 years (P = 0.656). A positive correlation coefficient was observed between the CARS questionnaire score, the SRS questionnaire score, the SCQ questionnaire score, and the ASDS ‏(P < 0.01). In the SRS questionnaire, the area under the ROC curve was 0.976, and in the SCQ questionnaire it was 0.953, both of which had a good and significant diagnostic value (P < 0.001). A sensitivity of 0.942 and specificity of 0.811 for the cut-off point of 62.5 were obtained in the SRS questionnaire. Additionally, a sensitivity of 0.865 and specificity of 0.925 for the cut-off point of 15.5 were achieved in the SCQ questionnaire. \u0000Conclusion: The SRS-2 and the SCQ are sensitive and specific tools for identifying and discriminating children with autism spectrum disorder.","PeriodicalId":38866,"journal":{"name":"Iranian Journal of Psychiatry","volume":"57 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140253194","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, recent research has uncovered a paradoxical aspect of perfectionism in these domains. This umbrella review seeks to offer a comprehensive overview of the intricate role that perfectionism plays in sport and exercise performance. \u0000Method: As an umbrella review, we systematically explored three widely used scientific databases—PubMed, Scopus, and ISI—to identify relevant systematic reviewes and meta-analyses investigating the relationship between perfectionism and sports performance. \u0000Results: After careful evaluation, eight studies met our inclusion criteria and were included in the study. These eight eligible studies comprised five systematic reviews and three systematic review and meta-analysis publications. These publications have explored the correlation between perfectionism and sports performance in teenager and adult populations, as well as professional and amateur athletes. Most of the original articles included in these studies had a cross-sectional design and some of them were longitudinal research. All reviewed articles reported a significant correlation between perfectionism and sports performance, regardless of gender and age. In general, the main consensus of these studies is a moderate to high positive correlation between perfectionistic strivings and sports performance, as well as a moderate to high negative correlation between perfectionistic concerns and sports performance. \u0000Conclusion: In summary, perfectionism exhibits both positive and negative effects on athlete outcomes. Maladaptive perfectionism is linked to adverse consequences, while adaptive perfectionism can yield positive effects. Promisingly, psychological interventions such as mindfulness-based approaches and ACT-based interventions show potential in reducing perfectionism and enhancing athlete outcomes. Future research should delve deeper into the intricate relationship between perfectionism and athlete performance and continue to devise interventions that counteract the detrimental effects of perfectionistic tendencies.","PeriodicalId":38866,"journal":{"name":"Iranian Journal of Psychiatry","volume":"22 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140253768","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thus, we explored SSEP patterns in PTSD patients during a stop-signal task to disclose possible impairments in these informative brain potentials. \u0000Method: 25 adult patients with PTSD and 25 healthy adults participated in this research. Subjects were assessed with electroencephalography while the tone signal stimuli at 40 Hz were used to evoke SSEPs and subjects performed a stop-signal task. The amplitude and phase of SSEPs were then computed in different brain regions. The subjects were also evaluated using the Mississippi PTSD questionnaire. Appropriate statistical methods such as repeated measure ANOVA were used to compare the two groups, and the correlation between SSEPs and clinical symptoms was assessed using Pearson correlation analysis. \u0000Results: Patients showed considerably poorer performance in the cognitive task (P < 0.01), accompanied by raised SSEP phase and amplitude in the anterior and midline regions compared to healthy controls (P < 0.05). The Mississippi total score was positively correlated with the SSEP amplitude in the midline region (r = 0.62, P < 0.05). Furthermore, based on ROC analysis, the SSEP amplitude in the midline region provided an excellent AUC value (AUC = 0.850) for distinguishing patients with PTSD from normal subjects. \u0000Conclusion: Current findings suggest that abnormalities in the anterior and midline cortical neural networks are involved in the pathophysiology of PTSD. Importantly, midline abnormalities may provide a clinically-relevant measure for researchers wishing to assess the use of biomarkers for early diagnosis of PTSD as well as to evaluate new therapeutic and management approaches in the treatment of PTSD.","PeriodicalId":38866,"journal":{"name":"Iranian Journal of Psychiatry","volume":"24 34","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140396277","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Accordingly, we investigated the omega-3 intake and the concurrent stimulation of the DLPFC by tDCS and hypothesized that the synergy of these two treatments can increase the obtained effect size in patients with depression and overweight. \u0000Method: This research was a double-blind randomized controlled trial (RCT) with a factorial design consisting of four treatment and control groups. The participants were females with depression and overweight on an outpatient basis. They received 5 ml/day omega-3 syrup (545 mg DHA, 620 mg EPA) or placebo adjunct with 12 sessions sham/tDCS stimulation administered for 3 weeks with anode-left/cathode-right protocol in the prefrontal cortex (1.5 mA, 15 minutes’ stimulation / 15-20 minutes’ rest intervals/one visit per week, 4 stimulations per visit). \u0000Results: tDCS or omega-3 alone did not significantly improve the executive functions, depression, food cravings, and weight in the experimental groups compared to the control group (P > 0.05). However, tDCS adjunct with the omega-3 had a significant and positive effect on improving weight change (P = 0.011; df = 1; F = 1.27; Eta = 0.108) with a power of 0.73 compared to the control group. Furthermore, their interaction led to an improving trend in executive functions and a decreasing trend in food cravings which are clinically important. \u0000Conclusion: tDCS could strengthen the omega-3 mechanisms of effect through stimulating its accumulation site in the brain (i.e., the DLPFC) and the synergistic effects of these two treatments result in weight control as well as an improvement trend in the executive functions and food craving in women. \u0000 ","PeriodicalId":38866,"journal":{"name":"Iranian Journal of Psychiatry","volume":"19 12","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140253135","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
