Factor Structure and Psychometric Properties of Measure Critical Thinking Scale Among Postgraduate Students at the College of Education in Qassim University

Abstract

The current study aimed to highlight the Factorial Structure of Critical Thinking Scale of university students completed in the current study using Exploratory Factor Analysis and Confirmatory Factor Analysis. and to verify its Psychometric Properties (Validity and Reliability) in its final version. The study focused on a sample of (253) Postgraduate Students at the College of Education in Qassim University; after the statistical analysis of the study data, the most important results of the study were as follows: Regarding the factorial structure of the critical thinking scale, using exploratory factor analysis and confirmatory factor analysis by describing the model, and using goodness of fit indicators. The results resulted in the suitability of the model to the data derived from the study sample, and five factors were extracted for the critical thinking scale, which were the Conclusion skill, measured by five items, the Deduction skill, measured by five items, the Interpretation skill, measured by five items, the skill of recognizing assumptions, measured by nine items, and the skill of evaluating arguments, it is measured in six items. As for the psychometric properties of the Critical Thinking Scale, the results showed that the scale in its final form has good psychometric properties that allow it to be used as a research tool in scientific studies and research.
