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.

Executive dysfunction is a hallmark of traumatic brain injury (TBI) and is associated with significant complications. Deficiency in problem-solving, emotion regulation, and attention is one of the most common phenomena after brain injury. This study aimed to evaluate the effectiveness of short-term intervention of dual executive function on problem-solving, emotion regulation, and selective attention in patients with traumatic brain injury. This quasi-experimental design used pre-test and post-test with a control group. Twenty subjects with brain injury were selected with the Purposive sampling method. They were randomly entered into two experimental and control groups (10 in the experimental group and 10 in the control group). After performing the pre-test, the experimental group received the short-term intervention and double executive function in 8 sessions of 90 minutes, while the control group did not receive any intervention. The assessment was performed in two stages of pre-test-post-test using a set of software tests of the Tower of London, Stroop and John and Gross (2003) Emotion Regulation Questionnaire. Analysis of covariance was used to analyze the data. The results showed a significant difference in the mean scores between the experimental group and the control group in all variables after the test. Therefore, it can be concluded that short-term intervention of dual executive function has a significant effect on improving attention, emotion regulation, and problem-solving in people with traumatic brain injury.
