“…Current findings on the social impact of ASD on TD siblings are inconsistent. Some studies showed that compared to siblings of TD children, siblings of children with ASD have more difficulties communicating and interacting with others socially (Dunn, 2007;Kaminsky & Dewey, 2001;Pourbagheri et al, 2018;Shojaee et al, 2018;Walton & Ingersoll, 2015) such as lack of affection, social interaction, conversation, relationships, and social appropriateness (Pilowsky et al, 2004). Other researchers also found that siblings of children with ASD are more likely to be introverted, internalized, or withdrawn (Barak-Levy et al, 2010;Hastings, 2003b;Macks & Reeve, 2007), which may explain low participation in social activities, problems with their peers, and poor academic performance (Barak-Levy et al, 2010).…”
