Introduction: Paving the way towards inclusive education, it is essential to aim for positive social outcomes for all students, including cultivating a positive self-concept and fostering acceptance and friendships with peers. Although self-concept, acceptance and friendships are interrelated, research focussing on the relationship between these constructs remains limited.
Method: This study examined the self-concept, acceptance and friendships of two groups of typically developing students in secondary education (n = 401) and two groups of students in special secondary education with either an intellectual disability (ID) (n = 58) or social, emotional and behavioural difficulties (SEBD) (n = 68).
