Although not inherent to the diagnosis, many individuals with autism spectrum disorders (ASD) display aggressive behavior. This study examined the experiences of families living with individuals with ASD who also demonstrate aggressive behaviors. Using a qualitative approach, semistructured interviews were conducted with parents of nine males with autism and aggression. Eight families' homes also were observed. Through constant-comparison analysis of interview data, triangulated with home observations, three central processes were identified: deleterious impact on daily routines and well-being of family members, limited supports and services, and financial strain. Emergent themes included isolation, exhaustion, safety concerns, home expenses, respite needs, and limited professional supports and alternative housing. Examination of families' experiences living with someone with ASD who is aggressive, and the impact of aggression on the supports and services that families receive, constitutes an important step in tailoring resources to best meet families' needs.
