[Norwegian Teacher Self-Efficacy Scale - Psychometric properties of the Polish version of the scale].

BACKGROUND: Self-efficacy refers to different spheres of human functioning and to different tasks, including teaching activity. It is regarded as an important personal resource related to coping with stress. This paper was aimed at presenting psychometric properties of the Norwegian Teachers Self-Efficacy Scale (NTSES), related to these beliefs in the group of teachers.

MATERIAL AND METHODS: Psychometric properties of the scale were evaluated on the basis of the data obtained from 404 teachers of elementary and middle schools.

RESULTS: Our analyses of exploratory and confirmatory factor revealed a 3-dimensional structure, but not a 6-dimensional structure of NTSES as obtained in the original Norwegian study. They also showed high reliability and construct validity coefficients. Teachers self-efficacy was positively correlated with general self-efficacy, internal locus of control and negatively with job burnout.

CONCLUSIONS: Although NTSES can be used in the study of Polish teachers, this should be done with great caution and the measure of global index of NTSES should be used. Additional studies on a larger sample of teachers are recommended. Med Pr 2017;68(6):743-755.
