Factorial validity of the Chedoke-McMaster Attitudes towards Children with Handicaps Scale (CATCH)

Abstract

The Chedoke-McMaster Attitudes towards Children with Handicaps Scale (CATCH) has been developed to measure the attitudes of children toward peers with disabilities. The present study aims to evaluate the factorial validity of the CATCH in a sample of 2396 students in 7th grade, including 179 students with disabilities and 2217 typically developing students. Each classroom included at least one student with a disability. The structure of the scale, as proposed by the developers, was tested and its stability was evaluated across gender, disability status, awareness of the disability status of classmates and having a classmate with a disability as a friend. Confirmatory factor analysis did not support the originally proposed subscale structure. Instead of the three proposed subscales, a single subscale including seven items was found. Strict factorial invariance was obtained across gender, disability status, awareness of the disability status of classmates and being friends with a classmate with a disability. Implications of these findings will be discussed.
