摘要:AbstractThis study addresses the social participation of students with special educational needs (SEN) in mainstream 7thgrade in Flanders (Belgium). Social participation (i.e., social interactions, peer acceptance, friendships, and social self-concept) was assessed by means of questionnaires among 86 students with autism spectrum disorder (ASD), 61 students with motor and/or sensory disabilities (MOTSENS) and 1926 normally developing classmates. Seventh grade students with ASD scored less favorably in all aspects. Girls with MOTSENS scored less favorably on some aspects of social participation than typically expected of their peers. The social participation of students with ASD and students with MOTSENS did not differ significantly.
