Purpose : This study was conducted for two purposes. The first purpose was to examine the psychometric properties of the Teacher Interpersonal Self-Efficacy Scale (TISES) for Turkish Physical Education (PE) teachers and the second was to analyze teachers’ interpersonal self-efficacy beliefs according to some demographic variables. Material : The study was conducted on 360 Turkish PE teachers. Confirmatory factor analysis was applied in order to verify the factor structure of the scale. Pearson’s product-moment coefficients were used in order to assess the correlations between the factors. For determining the reliability of the scale Cronbach Alpha coefficient was calculated. Multivariate analysis of variance was used to determine differences between the scores acquired from the scale and some independent variables. Results : The results confirm the 3-factor internal structure of the TISES. The results of the correlation analysis between the TISES subscales indicated significant and positive relationships. We also found acceptable values of the alpha coefficient, which confirms the TISES as a reliable instrument. Overall, all physical education teachers had positive self-efficacy beliefs on high levels. Whereas by gender significant difference was not found in self-efficacy beliefs, significant difference were found between teachers depending on years of experience and grade levels they taught. Conclusions : The reexamination of the scale led to a new scale structure comprised of three factors with sixteen items. The TISES is a relatively short questionnaire that allows researchers to measure interpersonal self-efficacy beliefs of PE teachers. The experienced teachers and the teachers who were employed at the high schools had higher self-efficacy belief levels.
