The present study employs structural equation modeling to assess the fit of a structural model encompassing obsessive beliefs grounded in executive functions, with emotion regulation as a mediating factor within a non-clinical population. The sample comprises 400 adults aged 20 to 50 in Tehran, selected from the general population via the available sampling method. The data collection instruments encompassed the Obsessive Beliefs Questionnaire (OBQ), the Executive Functioning Questionnaire -Adult Version (BRIEF-A), the Cognitive Emotion Regulation Questionnaire (CERQ), and the Behavioral Emotion Regulation Questionnaire (BERQ). The analysis of structural model fit indices revealed that they all fell within an acceptable range, thus affirming the suitability of the research's structural model. According to this model, executive functions exhibited significant effects on adaptive emotion regulation and maladaptive emotion regulation with standard coefficients of -0.45 and 0.76, respectively. Furthermore, adaptive emotion regulation with a standard coefficient of -0.10 and maladaptive emotion regulation with a standard coefficient of 0.63 were significantly impacted obsessive beliefs. To evaluate mediating relationships, the bootstrap test results were examined. It was found that the effect of executive functions on obsessive beliefs, mediated by maladaptive emotion regulation, was significant with standard coefficient of 0.478 at the p < 0.01 level. However, the effect of executive functions on obsessive beliefs, mediated by adaptive emotion regulation, was not significant with a standard coefficient of 0.045 at the p < 0.05 level. The findings of the study hold practical implications for the prevention of obsessive belief development and the alleviation of obsession-related suffering.

Objective: Sluggish Cognitive Tempo is one of the new disorders that has been seriously considered in cognitive psychology and can be influenced by various factors. Hence, the purpose of this study was develop a structural model to explain Predicting Sluggish Cognitive Tempo based on cognitive-emotional regularity and cognitive ability with the mediating variable of cognitive load in children. The research method was correlational and structural equation modeling. For this purpose, from among the statistical population of elementary school students in Tabriz city in the academic year of 1400-1401,Number of 200 students by screening method and using the SCT Penny et al scale (2009) were selected as the sample group. The instruments used in this study was include scales of Cognitive Emotion Regulation Garnfsky et al (2009), Cognitive Ability Questionnaire (Nejati, 2013),Cognitive load Klepsch et al (2017). the data were analyzed using structural equation modeling and SPSS 22 and SMART PLS software and Sobel test.The results showed that the conceptual model developed had a good fit with the data.The results of the structural relationships of the model showed that cognitive-emotional regularity and cognitive ability have a direct and significant effect on Sluggish Cognitive Tempo (p˂0.01). Also, cognitive ability had a direct and significant effect on cognitive load (p˂0.01), but cognitive-emotional regulation did not have a direct and significant effect on cognitive load (p˂0.15). The results of indirect relationships showed that cognitive-emotional regularity and cognitive ability with the mediating variable of cognitive load have a significant effect on Sluggish Cognitive Tempo (p˂0.01). Based on the results, the cognitive-emotional regularity and cognitive ability effect on cognitive load and Sluggish Cognitive Tempo.Therefore, by developing programs to educate and increase cognitive-emotional regularity and cognitive ability and reduce cognitive load in people with Sluggish Cognitive Tempo can be expected to improve Sluggish Cognitive Tempo in them.

Aim: This study aimed to prepare an Iranian version Of the Persian language and determine the reliability of the Mini-Mental State Pediatric Examination (MMSPE). Method: The Examination was translated into Persian language, and the instructions for its implementation. Some questions were changed to harmonize with the linguistic features and achieve Face validity. The research sample consisted of 40 children with behavioral problems of internalization and externalization and 100 children without these problems with an age range of 7 to 12 years who were selected by available sampling method according to the inclusion criteria. The research tools included The Child Behavior Checklist -Teacher Report Form (CBCL-TRF) of Achenbach & Rescorla (2001) and (MMSPE) of Scarpa and colleagues (2017). Results: The results of Mini-Mental State Pediatric Examination (MMSPE) in a healthy population of 38 total scores, between 24 - 38 with a mean of 34.16 and a standard deviation of 2.79, and a population with problems, between 8 - 27 and with a mean of 18.4 And the standard deviation of 4.97 was obtained. The discriminant validity was based on an independent t-test, and with 95% confidence was observed a significant difference between the cognitive performances of the two groups. In determining the internal reliability of the test, Cronbach's alpha coefficient for the whole test was 0.92. Conclusion: It seems that the Iranian version of (MMSPE) has good capability and reliability and is effective for cognitive screening and prognosis of various psychological and neuropsychological problems in children.

The present study aimed to examine the effectiveness of transcranial direct current stimulation in improving visual response control and everyday memory among patients with ischemic stroke. For this purpose, 20 patients with ischemic stroke (with an average age of 38 to 73 years) were selected by the available sampling method then they were assigned randomly into two experimental and control groups. Cognitive assessment of patients, including pre-intervention, evaluation immediately after the intervention and three months after intervention using Sunderland everyday memory Questionnaire (1983) and IVA+Plus (2015) (Integrated Visual and Auditory Continuous Performance) Test was done. The experimental group received 15 sessions for 20 minutes with a current of 2 mA Transcranial direct current stimulation (TDCS) for four weeks, and the control group did not receive any intervention. Data were analyzed by Repeated Measure. According to the findings, treatment of transcranial direct current stimulation has had a positive effect on improving the cognitive functions such as everyday memory and visual response control of patients with ischemic stroke in the experimental group . also obtained these results at the follow-up stage, which was 3 months after the intervention. (p<0/05). Therefore, this study has provided evidence for the effectiveness of a transcranial direct current stimulation program (TDCS) on everyday memory and visual response control in patients with ischemic stroke, which can improve memory and visual response control in this category of patients and can have a positive effect on the cognitive performance of patients.
