A Model of Family and Child Functioning in Siblings of Youth with Autism Spectrum Disorder.
Most TD siblings of kids with autism stay in the normal range—watch mom’s mood and sibling spats to spot the few who need help.
01Research in Context
What this study did
Stewart et al. (2018) asked moms to fill out packets about each child.
The families had one child with autism and one typically-developing brother or sister.
The surveys measured sibling mood, mom’s mood, and how the kids get along.
What they found
Most brothers and sisters scored in the normal range on every checklist.
Only a small slice, 6 to 23 percent, showed clinical-level worry or acting-out.
Moms who felt depressed and kids who fought often were the two flags that predicted trouble.
How this fits with other research
Lo et al. (2019) peered into the same brothers’ brains. They saw weaker white-matter cables that line up with social slips, giving the survey data a neural footprint.
Condy et al. (2021) swapped autism for intellectual disability and still found mom’s mood steering the family ship, showing the pattern crosses diagnoses.
Taylor et al. (2010) looked at marriage quality instead of mom depression and saw it matter for typical kids but not for kids with ID—so the driver changes with who is in the back seat.
Why it matters
You can calm worried parents by showing them the odds: most siblings do fine.
When a brother or sister does struggle, first ask about mom’s mood and how the kids play together.
A quick depression screen and a five-minute chat about shared games can guide you to the right referral faster than a full family battery.

03Original abstract
The potential clinical needs of typically developing (TD) siblings of youth with autism spectrum disorder (ASD) remain disputed. A total of 239 mothers of youth aged 6-17, including one youth with ASD (M = 11.14 years; simplex families) and at least one other youth (M = 11.74 years) completed online standardized measures of various familial factors and TD youth outcomes. Overall, only 6-23% of siblings were identified within the clinical range of emotional, behavioral, or social functioning. Both maternal depression and sibling relationship were identified as key pathways in predicting siblings' functioning within a good-fitting path analysis model. The current model is presented as a novel base for the development of future research and services for this unique population of children.
