Over the course of 3 decades, autism has evolved from a nearly unheard of disorder to one that is widely diagnosed (Centers for Disease Control and Prevention, 2009). This surge in diagnosis has initiated a renewed interest in autism research across disciplines. The impact of autism on the family is of particular significance to school psychologists working with students and their families. Although research confirms elevated rates of dysfunction in families with children who have disabilities, findings on the effects of autism on sibling relationships and well-being are generally divided (Macks & Reeve, 2007; Rivers & Stoneman, 2003). The purpose of this review is to bring awareness to a potentially at-risk population in schools by examining existing literature regarding the effect of autism on siblings.
