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
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
Psychologists have proposed two styles for thinking and processing information. Experiential system, which is automatic and non-verbal; And the Rational system, which is analytical and verbal. The aim of the present study was to evaluate the psychometric properties of the Rational- Experiential Inventory; and to find it's relationship with cognitive regulation of emotions. This cross-sectional study was performed by descriptive contextualization method. The statistical population consisted of all students of Islamic Azad and Sama Universities, Roodehen Branch, and 503 individuals were selected randomly via multi- period method and completed the Rational-Experiential Inventory (REI) and Cognitive Regulation of Emotions Questionnaire (Garnefski & Kraaij, 2006). Data were analyzed by exploratory factor analysis, Cronbach's alpha, and correlation coefficient. After analysis, four components were identified: Rational Ability, Rational Engagement, Experiential Ability, Experiential Engagement. The Cronbach's alpha coefficient was 0.682, 0.823, 0.695, 0.750, and the correlation coefficient in the retest was 0.79, 0.78, 0.73, and 0.76, respectively. In the validity of criterion, rational components had negative correlation with negative strategies of regulation of emotions, and the experiential components had positive correlation with these strategies. The rational- experiential inventory showed proper reliability and convergent validity, In general, Rational people used positive emotion regulation strategies more and negative strategies less. The Rational- Experiential Inventory had adequate reliability and convergent validity. It can be used to improve the teaching, and psychotherapy.
