Brief report: do the nature of communication impairments in autism spectrum disorders relate to the broader autism phenotype in parents?
When parents carry subtle autism traits, their autistic children tend to have steeper language hurdles—so screen parents and adjust therapy.
01Research in Context
What this study did
The team asked a simple question. Do parents who show autism-like traits have kids with worse language problems?
They looked at families who already had a child with autism. Each parent filled out a quick screen for the broader autism phenotype, or BAP. Then they tested the child’s real-life language skills.
What they found
Kids with at least one BAP-positive parent had rougher language. They struggled more with grammar and with back-and-forth talk.
The link showed up even when the parents themselves had no diagnosis.
How this fits with other research
Muller et al. (2022) extends the same idea. They found BAP-positive parents also over-rate autism symptoms on surveys. Together the papers say: check parent BAP status before you trust either parent report or child scores.
Bora et al. (2017) conceptually replicates the finding. A data-driven split still put parents of ASD kids in a high-BAP group, and the communication subscale drove the split.
Meier et al. (2012) flips the lens to siblings. Younger brothers and sisters who carry BAP traits also sound awkward in free conversation, showing the family pattern runs both up and down.
Why it matters
Before you write goals, ask who filled out the intake forms. If mom or dad scores high on BAP, the child’s language may be even weaker than the file shows. Add naturalistic conversation samples and plan extra pragmatic targets. Knowing the family trait pattern lets you start intervention one step ahead.

03Original abstract
Extensive empirical evidence indicates that the lesser variant of Autism Spectrum Disorders (ASD) involves a communication impairment that is similar to, but milder than, the deficit in clinical ASD. This research explored the relationship between the broader autism phenotype (BAP) among parents, an index of genetic liability for ASD, and proband communication difficulties. ASD probands with at least one BAP parent (identified using the Autism Spectrum Quotient) had greater structural and pragmatic language difficulties (assessed using the Children's Communication Checklist-2) than ASD probands with no BAP parent. This finding provides support for the position that genetic liability for ASD is associated with increased communication difficulties across structural and pragmatic domains.
