Validity and reliability of the Italian version of the Teachers' Sense of Efficacy Scale

Purpose This study investigates the construct validity and reliability of the Italian version of the Teachers' Self-Efficacy Scale (TSES) developed by Tschannen-Moran and Hoy (2001) and contributes to existing research aimed at exploring the elements and variables that influence teachers' self-efficacy levels. Design/methodology/approach The instrument, translated and adapted in Italian by Cardarello et al. (2017), was tested on a sample of 349 in-service second grade teachers with similar demographic profiles (gender, age, seniority). The study analyzes the data following the exploratory factor analysis. Findings The results of this research confirm the relevance of the three-factor model, but opens the possibility of a different organizational structure of the items within the scale. In fact, the results confirmed both the original TSES three-factor structure (student engagement, classroom management, instructional strategies) and a new four-factor structure. The new four-factor structure recognizes two new factors of an instructional nature, "Inclusive instructional strategies, learner-centered" and "Traditional instructional strategies, teacher-centered." The first one recalls beliefs about capabilities to use strategies and assessments focused on students' needs (inclusive perspective); the second one refers to the dimension of the disciplinary master. Originality/value According to the idea that teachers' self-efficacy is a multidimensional construct, the findings of this study invite to reflect upon the meanings of scale application in different cultural contexts and open a discussion about instructional strategies and the experience of teaching in Italy.
