Abstract
BACKGROUND & AIM: Teacher engagement can be defined as the teachers' effort and attention to teaching professional tasks, adequate emotions and commitment to relationships with students and colleagues in classroom and school. The Engaged Teacher Scale (ETS) is the frequently used scale, measuring teacher engagement developed by Klassen et al., 2013 in the UK, and consists of four dimensions: cognitive engagement (CE), emotional engagement (EE), social engagement with students (SES), and social engagement with colleagues (SEC). Therefore, the aim of this study was to measure the psychometric properties of the Persian version of the Engaged Teachers Scale (ETS). MATERIALS & METHODS: A total of 123 teachers who worked at Shahid Beheshti University of Medical Sciences, Tehran, Iran, were included in this study. The study participants were selected using the convenience sampling. The Persian version of a 16-item scale developed by Klassen et al. was validated by this study. Face and Content validity index and reliability were assessed after translation and cultural adaptation, and also construct validity was calculated by confirmatory factor analysis using the PLS22. RESULTS: Of the 123 study participants, 74 (60.01%) were females and 49 (39.9%) were males. The mean age of the subjects was about 30-40 years. The majority of the study participants were general practitioners (n = 75; 60.9%) and others were from different specialists. Content validity among 15 experts was 0.88. Confirmatory factor analysis for all 16 items loaded across four factors, and this four-factor scale showed a good fit in the Iranian community. Reliability using Cronbach's alpha was 0.79. The value of root mean square error of approximation (RMSEA) was 0.0094 with the 99% confidence interval, and also the goodness of fit index GFI value was 0.98. CONCLUSION: The Persian version of ETS had good validity and reliability in Iran and could be a useful tool for measuring the teacher engagement factors of faculty members that can be used by teachers and educational administrators.
