Prejudices towards people with intellectual disabilities: reliability and validity of the Italian Modern and Classical Prejudices Scale.

ABSTRACT

BACKGROUND: Prejudices and negative attitudes towards intellectual disabilities (IDs) may hinder social inclusion of ID individuals, limiting their well-being. This study investigated the psychometric characteristics of the Italian Modern and Classical Prejudices Scale (MCPS-IT) towards people with ID and the effects of gender, age and socio-economic status (SES) on prejudices. METHOD: The MCPS-IT was administered to 474 adults (69% women, age range 18-70 years, M = 33.13) in conjunction with a questionnaire evaluating socio-demographic information (SES), the contact and the education about ID people and the social dominance orientation. RESULTS: Results confirmed that Italian MCPS has a two-factor structure that measures in a reliable and valid way prejudice towards people with ID. Multivariate analyses of variance confirmed a weak gender difference in both scales and age differences in modern scale. No SES differences were found. CONCLUSION: The Italian MCPS represents a valid scale that can be used to monitor the social context of people with ID.
