Abstract

The current research aimed to prepare a scale for cognitive bias among university students, to verify the scale’s psychometric properties (validity - reliability), and to verify its suitability for use in the Egyptian environment, by providing indicators about the scale’s reliability and validity. Participants were (387) students who were enrolled in the third year at Faculty of Education in Tafhna Al-Ashraf. The researcher used the descriptive method. Results revealed that the scale had high validity indicators, as it had multiple aspects of validity, which were (arbitration agreement, and factor analysis). Also, the scale had high reliability indicators that allow it to be used, as the reliability value was (0.951) using Cronbach's alpha for the total score of the scale, and was (0.956) using test-retest. Also, results revealed that the dimensions of the scale revolve around four dimensions (irrational judgments, personal subjective expectations, perceptual distortion, and psychological deficit).
