“…The influence of having a brother or sister with exceptionalities can have a confluence of effects on a typically developing sibling's perception of themselves, their brother or sister, and the family itself. The majority of studies examining effects on typically developing siblings focus on developmental disorders (e.g., autism spectrum disorder; Aronson, 2009;Meadan et al, 2010;O'Laughlin, 2006), chronic illness (e.g., cystic fibrosis, diabetes ;Fleary & Heffer, 2013;Foster et al, 2001;Incledon et al, 2015;Newcon, 2004;Ryan, 2009;Vanderwerp, 2011;Wennick & Huus, 2012), mental health problems (Barnett & Hunter, 2012;Giallo et al, 2012), neurological disorders (e.g., Tourette syndrome; Maleki-Tehrani, 2006), or physical disabilities (Pit-Ten Cate & Loots, 2000). Thus, many of the studies investigating the effects of exceptionalities on typically developing siblings involve children with visible disorders.…”
