Abstract
This study was designed to investigate the association of quality of Portuguese inclusive preschool classrooms with the social acceptance of children with disabilities. Sixty-four inclusive preschool classrooms from 28 randomly selected school groups from the district of Lisbon participated in this study. Classroom quality was not associated with children's social acceptance peer ratings. Only target children's chronological age and severity of disability predicted social acceptance outcomes, with peers without disabilities attributing higher social acceptance scores to younger children and children with more severe limitations. Findings suggest the need to improve the quality of Portuguese preschool classrooms, namely, features of adult-child relationships and the degree of individualization, up to a level likely to exert a positive influence on children's social outcomes. Child predictors of social acceptance are discussed within a peer culture perspective.
