Abstract
The present study aimed to investigate the psychometric properties of the Dispositions to Critical Thinking Inventory (DCTI) among a normal sample of Iranian students. The present study is a correlation study. The population of the study consisted all students of Tehran’s universities (Shahid Beheshti University, Tehran University, and Shahed University). 330 students (175 females, 155 males) were selected by multi-stage cluster sampling. At first, the inventory was translated through double translation method and verified by the specialists. To assess construct validity, the exploratory factor analysis as well as internal consistency (Cronbach’s alpha) was used. To assess the convergent validity, the correlation coefficients between the DCTI and the California Critical Thinking Disposition Inventory (CCTDI) was used. Finally, in order to assess the reliability of the questionnaire, the test-retest after 2 weeks (N=40) and Cronbach’s coefficients were employed. Results from factor analysis and varimax rotation to determine construct validity showed that this inventory was saturated by three factors, innovativeness, maturity and commitment. To investigate its convergence validity, the results of correlation scores of the dispositions of critical thinking with the California critical thinking skills test score showed that the correlation between the critical thinking skills score and the California critical thinking skills test score was not significant, but it had a significant relationship with the two other factors. Using the internal consistency method, the Cronbach’s alpha for each of the subscales was calculated and following results obtained: 0.61 for innovativeness subscale, 0.38 for maturity, and 0.81 for commitment, which indicates dispositions to the critical thinking subscales had a positive and significant correlation with each other and with the total score of the inventory (r = 0.75). The obtained results of test-retest scores after one-week interval and internal correlation coefficient were calculated as follows: 0.564 for creativity, 0.372 for maturity, and 0.682 for commitment subscales.
According to the results of the present study, the DCTI can be used for educational and research goals in Iranian population.

Abstract
This study aimed to evaluate the psychometric properties flow metacognitions questionnaire (FMQ) on the student population took place. For this purpose, 390 students of Urmia University were selected by multi-stage cluster sampling, then flow metacognitions questionnaire (FMQ), Positive Metacognitions and Meta-Emotions Questionnaire and Meta-Cognitions Questionnaire were distributed among them to respond. After collecting data to determine the psychometric properties of the flow metacognitions questionnaire (FMQ), initially validity of the Questionnaire was assessed by Cronbach's alpha, retest and splitting coefficient, the criterion validity with Positive Metacognitions and Meta-Emotions Questionnaire and Meta-Cognitions Questionnaire. As well as its factor structure was assessed by using confirmatory factor analysis. The results of the factor analysis indicated that the flow metacognitions questionnaire (FMQ) has two factors, check the validity of the questionnaire using Cronbach's alpha, retest and splitting coefficient reflects the stability of the scale, the criterion validity of the questionnaire with other questionnaires Showed desirable discriminant and convergence validity. Overall, the findings indicated that flow metacognitions questionnaire (FMQ), has good psychometric properties in sample of student and normal population, and tool can be used in studies in the Iranian culture.

Abstract
In regard to collecting data, method of the study was descriptive - instrument making one Item analysis, internal consistency cofferient and test-retest demonstrated that the items and factors were satisfactory. Confirmatory factor analysis, also, confirmed the model with five factors. Therefore CD had a proper validity and reliability to measure Cognitive Disability amony Iranian people. Thus, it can be employed as an instrument in related research and treatment.

Abstract
Critical thinking helps people to consider and analyze a wide range of information. The importance of strengthening this skill is significant for managers because it leads to success and the overcoming of crises. The Watson-Glaser Critical Thinking Appraisal Test, is a tool for measuring critical thinking and has been designed to combine the aspects of skill and tendency for critical thinking. The purpose of this study is to investigate psychometric properties of this test amomg the Iran Gas Transmission Company managers and to evaluate its psychometrics properties using validation and reliability methods as suitable tools for identifying and measuring critical thinking in the Iranian sample, especially among managers. The sample of the present study included 472 staff managers, who participated in the study of "The Development of Psychological Identity of the Managers at the Iran Gas Transmission Company" in 2018-2019, and responded to 80 questions of a computer-based version of the test. The findings of this study showed that the test on our sample society has four dimensions of analytical thinking, evaluation, interpretation, and assumption while its original version has five dimensions. Moreover, an exploratory factor analysis revealed that the two components of inference and inferring had to be merged and this new component was called analytical thinking. In addition, confirmatory factor analysis of the model with the four components was meaningful and desirable in all fit indices of the model. According to the results of this research, the Watson-Glaser Critical Thinking Appraisal Test can be used to achieve research goals.

Abstract
In spite of increasing importance of attentional control in conceptualization of psychopathology, there are a few scales to measure it. It is necessary to use valid and reliable scale to study this construct in Iranian studies.This study aimed to provide and investigate psychometric characteristics of Persian version of the attentional style questionnaire.The sample of 426 students were selected by available sampling and completed persian version of the attentional style questionnaire, attentional control (Derryberry &Reed, 2002) and repetitive thinking (Ehring et al, 2011) scales. Construct validity were evaluated through confirmatory factor analysis. Convergent and divergent validity were assessed by pearson correlation. Reliability was calculated using Cronbach s alpha method, test-retest and Composite reliability.factor analysis indicated that two-factor model (congnitive avoidance/distractibility and focusing) provided good model fit. Significant correlations between these factors and attentional control, and repetitive thinking scales confirmed convergent and divergent validity. Cronbach s alfa for both factors were 0/75 and test-retest coefficient for cognitive avoidance/distractibility and focusing were 0/88 and 0/73 respectively also composite reliability were 0/81 and 0/84 respectively. According to the results, Persian version of attentional style questionnaire characterized two factors and has been demonstrated to have acceptable validity and reliability to use in psychological researches in Iranian population.
