Cross-validation of the Norwegian Teacher's Self-Efficacy Scale (NTSES)

The study assesses the psychometric properties of the Italian version of the Norwegian Teacher Self-Efficacy Scale – NTSES. Multiple group confirmatory factor analysis was used to explore the measurement invariance of the scale across two countries. Analyses performed on Italian and Norwegian samples confirmed a six-factor structure of the scale with a strong factorial invariance. The analyses conducted on the Italian sample supported good internal consistency and test-retest reliability. The Italian version of the NTSES showed expected correlations with measures of job-related well-being. These results confirm the good psychometric properties of the Italian version of the NTSES.

► Cross validation of Norwegian Teacher's Self-Efficacy Scale (NTSES). ► NTSES showed a strong factorial invariance across Italian and Norwegian samples. ► NTSES (Italian version) had good internal consistency and test-retest reliability. ► NTSES (Italian version) had expected correlations with job variables.
