Validation of the Arabic version of the attitudes toward intellectual disability questionnaire (ATTID-AR)

The ability to examine people's attitudes about individuals with an intellectual disability is an important step toward their inclusion in society, as negative attitudes are one of the challenges to an inclusive society. The aim of this study is to investigate the psychometric properties of an Arabic translation of the short version of the Attitudes Toward Intellectual Disability (ATTID) questionnaire.

Participants were 903 who completed the Arabic version of the ATTID. Internal consistency was assessed using Cronbach's alpha and McDonald's omega. Confirmatory factor analysis (CFA) was conducted to evaluate the structural validity. Content validity was examined using expert ratings, and both concurrent and convergent validity were assessed via correlation analyses with existing instruments and demographic variables.

The findings provided evidence of internal consistency based on Cronbach's alpha and McDonald's omega. Evidence related to internal structure, content, and relations to other variables was examined, yielding generally positive indications for the psychometric properties of the scores. In addition, confirmatory factor analysis indicated a five-domain structure consistent with the proposed model.

Overall, the findings provide evidence supporting the psychometric properties of the scores obtained from the Arabic short version of the ATTID for assessing multidimensional attitudes toward individuals with intellectual disabilities in Arabic-speaking populations.
