The current study was conducted to investigate psychometric properties of the executive skills questionnaire-revised (ESQ-R) in Iran. We carried out a cross-sectional study following linguistic validation and pilot investigation. The forward-backward translation method was used to translate the questionnaire from English into Persian Prior to pilot testing. The participants consisted of 1337 male and female students studying in Iranian universities. For data analysis, confirmatory factor analysis (CFA) were used. Additionally, internal consistency analyzed by test-retest and Cronbach’s alpha (Reliability). The coefficient alpha estimates of reliability were for the first factor (planning) 0.84, the second factor (time management) 0.78, the third factor (emotion regulation) 0.76, the fourth factor (organization) was 0.72 and the fifth factor (behavior regulation) was 0.70. The results of confirmatory factor analysis were in an acceptable range for the questionnaire. The findings demonstrated that ESQ-R has good psychometric properties to measure executive skills among Iranian students. Therefore, the questioner can be used in future in health or educational settings.

Abstract
The goal of this study was to develop and evaluate educational motion graphics to enhance components of executive functions in children with learning disabilities. The study used a quasi-experimental design with pre-test-post-test evaluation and a control group, and the sample population consisted of all students aged 7-11 years with learning disorders from treatment centers in the cities of Tehran, Isfahan and Qazvin. Students were selected via a convenience sampling method and a total of 18 participants volunteered to participate in the experiment. The 9 experimental group participants and 9 control group participants were matched by age and gender. Then, the motion graphics, which were based on scientific sources and created using advanced animation software, were performed for the experimental group for 10, 45-minute sessions. Subjects were assessed using the BRIEF Executive Functions Questionnaires (2000) and the Lufi Perseverance Questionnaires (1987) as a pre-test and a test at the conclusion of the program. The results indicated that there was a significant difference between the experimental and control groups’ scores in the components of executive functions, namely attention, inhibition, planning, organization, reminders, perseverance and effort. Furthermore, it was found that utilizing educational motion graphics was an effective way to enhance executive functions in children with learning disorders.

ABSTRACTPerformance-based measures have shown some limitations in the assessment of executive functions (EF) and rating scales have been proposed as an alternative. This study examined the psychometric properties of the Persian version of the Behavior Rating Inventory of Executive Function, Second Edition, BRIEF-2 parent - form in students aged 13 to 18 years. Participants were 300 students, 148-girl (49.3%) and 152-boy (51.7%) between 13 and 18 years old (M = 9.15; SD = 1.92). Samples were selected from regions (north, south, east, west and center) in Tehran city. The analysis of the internal structure using confirmatory factor analysis reveals that the model with three indexes (Behavioral, Emotional and Cognitive) and nine scales (Inhibit, Shift, Self-Monitor, Emotional Control, Initiate, Working Memory, Plan/Organize, Organization of Materials and Task-Monitor) showed good fit to the sample. The Cronbach's alpha values for the index scores ranged from.91 to.93, with alpha for the individual scales ranging from.87 to.92. Results showed that Persian version of the BRIEF-2 parent Form demonstrated high internal consistency and test–retest reliability. Convergent validity was obtained for BRI (AVE = 0.52), ERI (AVE = 0.54) and CRI (AVE = 0.58). In addition, composite reliability (CR) was reported for BRI (CR = 0.85), ERI (CR = 0.87) and CRI (CR = 0.83). According to the findings, it can be said that the Persian version of the BRIEF2 scale has the necessary convergent validity and composite reliability. The findings support the factorial validity of the BRIEF-2 scores, suggesting that it is an adequate instrument to evaluate executive functioning reported by parents and caregivers. According to the findings, it can be said that the Iranian version of the BRIEF-2 has good psychometric properties and can be a good tool for use in clinical and research situations.

Introduction: Due to the wide range of executive functions, Existing questionnaires measure some aspects of these functions. Behavior Rating Inventory of Executive Function (BRIEF )has a greater comprehensiveness and it's made based on the latest insights on executive functions. Objective: The purpose of this study was to validate of this questionnaire in Iranian society.Method: This research is descriptive, a sample of 516 people was selected by a cluster sampling method from Tehran, East Azarbaijan, West Azarbaijan and Kurdistan provinces. In this way, the final sample was reduced to 441 subjects. Statistical analysis was performed using SPSS 20. Results: The present inventory consists of eight scales and from the combination of these eight scales the behavioral indicator and cognitive index are obtained. Finally, by combining the score of 8 scales, the total score of the BRIEF test is obtained. The results show that calculated Cronbach's alpha for 8 scales of the questionnaire is between 68 to 86. Also, calculated Cronbach's alpha for behavioral adjustment index, cognitive index and total score of BRIEF questionnaire were 0.86, 0.89, and 0.93 .Conclusion: According to the findings of this study the brief questionnaire in Iranian society has a desirable credibility as a tool for evaluating executive functions and It is used in research and clinical work as a valid tool.
