Factor structure and measurement invariance of the Students' Self-report Checklist of Social and Learning Behaviour (SSL)

The SSL is a new self-report questionnaire for students aged 9 to 19 years measuring ten facets of social and learning behaviour (cooperation, self-perception, self-control, empathy, self-assertion, social relationships with peers, endurance, concentration, independence, diligence). Based upon a confirmatory factor analysis (CFA) approach, the present study examined the factor structure and measurement invariance across gender of the SSL with 4045 German students. Results of CFA provided strong support for the presumed ten-factor structure of the SSL and showed that the ten-factor structure (factor loadings and item intercepts) of the SSL was invariant across gender. These results suggest that the SSL can be used as a confidential instrument for measuring ten specific facets of students' self-reported social and learning behaviour.
