The development of siblings' understanding of autism spectrum disorders.
Siblings understand autism better as they grow, but parents routinely over-rate that grasp, so always test comprehension first.
01Research in Context
What this study did
Glasberg (2000) asked brothers and sisters what autism means. They used kid-friendly interviews. Parents answered the same questions so the team could compare views.
The study wanted to see if siblings grow in autism understanding the same way kids learn about colds or chicken pox.
What they found
Understanding does grow with age, but it stays behind typical illness-concept growth. Many eight-year-olds still think autism is like a tummy ache that goes away.
Parents usually believe the sibling 'gets it' far better than the child really does.
How this fits with other research
Matson et al. (2013) extends this picture. They show that even when a child with autism talks well, warmth and conflict between siblings stay the same. Knowing facts does not automatically fix feelings.
Hilton et al. (2010) adds a twist: behaviour problems, not the autism label itself, drive sibling stress. Glasberg (2000) warns us that parents may miss both the knowledge gap and the stress link.
Tavassoli et al. (2012) let siblings speak for themselves. They list nine life-quality themes like 'time for me' and 'mutual understanding.' The 2000 finding helps explain why siblings ask for these things—they are still working out what autism means to them.
Why it matters
Before you teach a sibling support class, check what the child actually knows. Use simple, concrete language and draw pictures. After the lesson, ask the child to repeat the idea in their own words. You will often catch big gaps that parents swear are not there. Fixing the knowledge mismatch lowers confusion and opens the door to the behaviour-focused help shown in later studies.

03Original abstract
While professionals commonly advocate sharing information about autism spectrum disorders with siblings, no guidelines currently exist that describe what types of information might be relevant for siblings at different ages. To address this issue, the interviewing method described by Bibace and Walsh (1979, 1980), which measures cognitive sophistication in thinking about illness, was adapted to examine perspectives on autism spectrum disorders. Sixty-three siblings of individuals with autism or related disorders were interviewed using this measure. Parents were given the same interview as their child, and asked to predict their child's responses. Children's reasoning became more mature with age, but developed at a delayed rate compared to norms for illness concepts. Although accurate in estimating their child's understanding of the definition and cause of their sibling's diagnosis, parents tended to overestimate their child's understanding of the disorder's impact.
