Sibling Adjustment and Sibling Relationships Associated with Clusters of Needs in Children with Autism: A Novel Methodological Approach.

Participants were self-selected families reached through a national autism charity, and the number contacted is unknown, so they may not represent all families of autistic children. The families were from a relatively high-income bracket, which may mean greater resources than other families. Autism diagnoses were reported by the primary caregiver and not verified by a clinician. Secondary carer reports and sibling self-reports had smaller sample sizes, so not all families were fully represented. Only one sibling per family was studied, although some families may have multiple siblings. Secondary carers completed only one sibling measure, so their perspective is less detailed. The paper describes associations between groups of children's needs and sibling outcomes; it does not test an intervention.

No funding or conflict-of-interest declaration is reported in the supplied text. Recruitment involved a national autism charity distributing invitations.

Do not conclude that siblings of children with the most complex autism-related needs are automatically the most poorly adjusted. Primary carer ratings showed more emotional and behavioral problems in siblings of children in cluster 3 than cluster 5, while secondary carers reported no group differences, and the study cannot show cause.
