Sluggish Cognitive Tempo is used to describe a particular type of attention deficit, concentration, and slowness in information processing. The aim of this study was to investigate the psychometric properties of the Sluggish Cognitive Tempo Scale (SCTS) of the parent form among Iranian children. The present study is a descriptive study. A sample of 1700 people was selected from the provinces of Tehran, East Azerbaijan, West Azerbaijan, Kurdistan, Fars and Khorasan using cluster sampling method. 122 subjects were excluded from statistical analysis due to incomplete answers to the questionnaires and thus the final sample was reduced to 1578 parents. The confirmatory factor analysis method and internal consistency were used to compute the Sluggish Cognitive Tempo Scale factorial validity and reliability, respectively. Also, in order to examine the construct validity of the Sluggish Cognitive Tempo Scale, we computed correlations between different dimensions of Sluggish Cognitive Tempo Scale with Attention Deficit Subscale of Mental Health Assessment Questionnaire for Children and Adolescents. The results of statistical results showed that this scale has structural validity, criterion and convergence in Iranian society. The results indicate that the scale is three factors and also the validity of the scale using Cronbach's alpha method and retest test after Approved two weeks. According to the findings of the present study, the parent form of the Sluggish Cognitive Tempo Scale (SCTS) has a good validity and reliability and it can be used in research related to slow cognitive multiplication in Iranian society.

One of the factors that can be the link between our intentions and actions and their external consequences is human agency, which indicates the conscious design and intentional execution of actions by the individual in order to influence future events.Objective and Method: This research with a developmental approach of psychometric method and method 1, examines the psychometric indices of the Human Factor Characteristics Scale using the classical theory of test score measurement and the graduated question-answer theory. The purpose of this study, which included high school students in Tehran, was selected by cluster sampling of 500 people as a sample size and statistical analysis was performed on 481 data. To collect the data, the ion Human Agent Characteristics Scale (2011) was used and the research questions were evaluated using IRTPRO and SPSS software.Results:The assumption of local independence based on Pearson x2 index was established by applying Simjima's calibrated question-answer theory and the assumption of being one-dimensional based on the analysis of multidimensional question-answer theory. Diagnosis parameters with question-answer approach and classical approach Test score Both item 25 approach had the lowest and item 2 had the highest diagnosis parameter. The answer thresholds for all the questions were so far apart that no option was covered by the other option, and the options were independently selected by individuals at intervals of theta. The total scale was calculated with Cronbach's alpha of 0.945, intentionality of 0.894, foresight of 0.780, self-reactivity of 0.871 and rethinking of 0.762. Also, the role of each item in internal consistency was investigated by the loop method, which all questions had a favorable role in internal consistency of this scale. The value of the validity coefficient obtained from the question-answer theory was obtained by marginal method for intentionality 0.92, forethought 0.85, self-reaction 0.91, rethinking 0.83..

AbstractThe aim of this study was to investigate the validity, reliability and factor structure of the "How I Think" questionnaire to assess cognitive distortions in Iranian students. The present research design is descriptive and psychometric studies. The statistical population of this study included all male high school students in city Dezful in the academic year 1399-1400, from which 316 students were selected by multi-stage random sampling and completed the How I think and Bass and Perry Aggression Questionnaires (for Convergent validity). Factor analysis, Cronbach's alpha and Pearson correlation were used to analyze the data using SPSS and AMOS 20 software. The results of factor analysis showed that the questionnaire consists of six factors and has good fit indices. The convergent validity of this questionnaire indicated a satisfactory correlation between the dimensions of the scale "How I think" with the Aggression Questionnaire (p <0.01). Cronbach's alpha and Split- half coefficients for the whole scale and its dimensions ranged from 0.66 to 0.92.The conclusion is that the Persian version of the "How do I think" questionnaire for measuring cognitive distortions in Iranian students has acceptable psychometric properties and can be used as a valid tool in research, educational and clinical situations.

The Big Five Inventory (BFI) is one of the most widely used personality questionnaires, but very few studies have been conducted on its psychometric properties in Iranian population. This study was carried out with the aim of studying the psychometric properties of the BFI questionnaire. For this purpose, 390 university students in Tehran (210 girls and 180 boys) with an age range of 18 to 56 years (M = 27.52; SD = 8.79) were selected using the convenience sampling method and completed BFI and NEO-FFI questionnaires. Cronbach's alpha, multitrait-multimethod matrix, and confirmatory factor analysis were used to estimate the psychometric properties of the questionnaire. The result of the confirmatory factor analysis showed that 15 of the 44 items did not have a strong factor loading (higher than 0.40) on the corresponding factors and were therefore removed from the questionnaire. The fit indices showed that the Persian version of 29 questions (BFI-29) with 5 factors has a good fit with the data. The reliability analysis also showed that the range of Cronbach's alpha coefficients of the factors is from 0.70 to 0.79. The lowest Cronbach's alpha coefficient was related to agreeableness factor and the highest was related to conscientiousness. The findings from the multitrait-multimethod matrix showed that the BFI-29 questionnaire has good convergent and divergent validity with the NEO-FFI questionnaire. In general, based on the results of the present study, it can be said that the BFI-29 questionnaire has desirable psychometric properties and whenever a short tool for personality measurement is needed, this questionnaire can be used.

Background & aim: Psychosocial factors are crucial for patients with coronary artery disease (CAD), but the type and outcome of anxiety disorders in these patients have not been studied as much as other risk factors. Therefore, the aim of the present study was to determine and investigate psychometric indicators of generalized anxiety disorder (GAD) in CAD patients. Methods: The present research applied a descriptive-cross-sectional method. The statistical population included all patients with CAD referred to Golestan Hospital in Ahvaz, Iran,in 2022. Two-hundred and nine participants were selected using available sampling method and completed the 7-item scale of generalized anxiety disorder (GAD-7). The collected data were analyzed using Cronbach's alpha, Pearson's correlation coefficient, independent t test, one-way analysis of variance, exploratory factor analysis and Imus. Results: The mean and standard deviation of age for men was 58.47±10.45 and for women it was 62.40±9.47. 152 people (72.73%) were men, Cronbach's alpha was equal to 0.936 and a one-factor model was obtained using exploratory factor analysis (EFA). Confirmatory factor analysis (CFA) indicated that the modified one-factor model of GAD-7 (this factor is named GAD-7) had a good fit. Conclusion: since CAD patients experience high anxiety, it is important to use a short and valid tool to determine their anxiety. Therefore, GAD-7 has worthy psychometric properties for use in patients with CAD.

Aim and Background: The burden of caring for the mentally ill is effective as an important factor in maintaining the patient in the community. There is no specific measurement tool for assessing and measuring this issue in schizophrenic patients. The aim of this study was to evaluate the psychometric properties of the Schizophrenia Caregivers Questionnaire. Methods and Materials: The design of the present study was descriptive-correlational. About 147 caregivers of schizophrenia patients admitted to Roozbeh Psychiatric Hospital and the Family Support Organization of Schizophrenia patients in Tehran were selected as a sample. Three questionnaires of schizophrenia caregivers, quality of life questionnaire and positive and negative symptoms questionnaire were used to collect data. Data were analyzed using Cronbach's alpha, correlation coefficient and heuristic factor analysis. Findings: In exploratory factor analysis, six factors (caregiver ability, interpersonal relationships, independence, social status, caregiver concern and caregiver fatigue) were extracted. In total, these six factors were able to explain 70. 7% of the variance of the 32 questions of this questionnaire. The internal consistency of the subscales was also obtained with Cronbach's alpha in the desired range. The Varimax rotating matrix showed that all questions were usable. Conclusions: The results of statistical analysis show that the schizophrenia patient care burden questionnaire has acceptable psychometric properties and can be used as a valid tool (with a validity coefficient of 0. 67) in the Iranian population.

The present study aims to evaluate the psychometric properties of the Persian version of the PERMA-profiler in students. The research is descriptive correlational and applied. The statistical population of the study was university students of different educational levels with Internet access in academic year of 2019-2020, the sample size was 568 (385 females, 183 males) and the sampling method was convenience sampling. The research instruments were PERMA-profiler, Ryff's Scales of Psychological Well-being (RSPWB-18), Satisfaction with Life Scale (SWLS) and Depression, Anxiety, and Stress Scales (DASS-21). First, the questionnaire was translated and its content and face validity were examined. Data was collected by an online questionnaire. Construct validity was assessed by CFA and the 5-factor structure of the questionnaire was confirmed. The correlation of the questionnaire with RSPWB-18, SWLS, and DASS-21, indicated the appropriate convergent and divergent validity of the construct. The internal consistency of the instrument with Cronbach's alpha and Guttmann coefficients was evaluated suitable for the subscales and the total score (0.66 to 0.95), and the test-retest with high coefficients (0.74 to 0.86) showed the stability of the instrument. Finally, based on the results of this study, PERMA-profiler has good validity and reliability for use in the student community.
