“…Some researchers report that children with a brother or sister with autism are at a higher risk for internalising and externalising behaviour problems (Fisman et al, 1996;Fisman, Wolf, Ellison, & Freeman, 2000;Gold, 1993;Hastings, 2003a;Rodrigue, Geffken, & Morgan, 1993;Ross & Cuskelly, 2006;Verte, Royers, & Buysse, 2003;Wolf, Fisman, Ellison, & Freeman, 1998) and for impoverished sibling and peer relationships (Bägenholm & Gillberg, 1991;Hastings 2003a;Kaminsky & Dewey, 2001) compared to siblings of children with another disability or typically developing children. Other researchers suggest that siblings of children with autism may not be at increased risk for such difficulties (Hastings 2007;Kaminsky & Dewey, 2002;Mates, 1990;Pilowsky, 2004).…”
