“…Studies that have compared both mothers and fathers of children with autism to parents of children with other diagnoses suggest that mothers are affected more negatively than fathers and that families of children with autism experience more problems than families of children with other diagnosed conditions (Dumas, Wolf, Fisman, & Culligan, 1991;Rodrigue, Morgan, & Geffken, 1990, 1992Wolf, Noh, Fisman, & Speechley, 1989). The comparative focus has also been extended to siblings of children with autism, who have been found to have higher levels of both internalizing and externalizing behavior problems and lower rates of social interaction with their brother or sister with autism than other groups (Fisman et al, 1996;Knott, Lewis, & Williams, 1995;Rodrigue, Geffken, & Morgan, 1993).…”
