Teachers’ Irrational Belief Scale: Psychometric Properties of the Greek Version and Measurement Invariance across Genders

Irrationality refers to human thoughts and beliefs that signify lack of rationality and entail erroneous perceptions about situational, personal, or collective idiosyncrasies, while it is independent of one’s intellectual ability. Irrational beliefs are ubiquitous in all social and cultural groups a...
