First Evidence on the Validity of the Students’ Relatedness Scale (SRS) and of the School Well-being Scale (SWS)

Several studies suggest that students’ relatedness and well-being are related to students’ success at school and healthy development. The purpose of this study is to examine psychometric properties and construct validity of the Students’ Relatedness Scale (SRS) and of the School Well-being Scale (SWS). Multi-group confirmatory factor analyses (MCFA) are performed to test the theoretical structure of the two scales and their metric invariance across gender. Results of MCFAs are consistent with the scale structure hypothesized for SRS and SWS, and show the scales’ measurement invariance across gender. The internal consistency of the scales ranged from .72 to .85.
