Resumo

The main purpose of this study was the construction and validation of a scale of attitudes towards people with disabilities, mainly directed at professionals in the areas of health and education. Participants were 976 professionals from different fields (health, education, career counseling, media, administration), with an age range between 18 and 65 years. 49.1% were women. After analyzing agreement between expert judges to evaluate the content of the items, three types of analysis were performed: comparison of correlation structures, exploratory factor analysis by common factor method, and confirmatory factor analysis on polichoric correlations matrix. Two models were compared: Unidimensional and three-correlated factors. Results have shown good metric qualities of reliability (internal consistency, reliability of individual indicators, construct reliability and standard error of measurement) and validity (content, convergent and discriminant).
