Psychometric properties of the Greek-language Opinions Relative to Inclusion of Students with Autism Spectrum Disorder scale (ORI-ASD) and Teachers' Sense of Efficacy Scale – Autism Spectrum Disorder (TSES-ASD)

The translated and adapted ORI-ASD and TSES-ASD showed good psychometric properties in a Greek sample of teachers and university students. The current study indicates that the ASD-adapted versions of the ORI and TSES are reliable and valid scales for rating pre-service and in-service teachers' opinions related to perceived self-efficacy and the inclusion of students with ASD. Our findings could have important implications for policy and practice relating to inclusive education.
