Sources of Teacher Efficacy Questionnaire: Psychometric characteristics of Polish adaptation

Abstract

The study presents the theoretical basis and psychometric properties of the Sources of Teacher Efficacy Questionnaire (STEQ), by C. K. W. Hoi and co-authors in the Polish adaptation. The sample included 946 teachers. Confirmatory factor analysis conducted showed a good fit of the four-factor model. Analyses confirmed the reliability and validity of the scale. The major contribution to explaining the sources of teachers' sense of efficacy comes from experiencing mastery. Knowing the sources of teachers' efficacy allows for a better understanding of their self-efficacy and, consequently, their engagement in teaching.
