Emergence of autism spectrum disorder in children from simplex families: relations to parental perceptions of etiology.
Parents who remember sudden skill loss are more likely to blame vaccines—ask about onset story at intake.
01Research in Context
What this study did
The team sent a short survey to 500 parents who each had one child with autism.
They asked two things: how did the autism first show up, and what do you think caused it?
Parents picked either slow early signs or sudden loss of words and skills called regression.
What they found
Kids who lost skills suddenly made up one third of the group.
Parents in that group named vaccines or toxins as the cause twice as often as other parents.
The belief stayed strong even when kids had no medical link to shots.
How this fits with other research
Austin et al. (2015) asked the same questions to the general public and daycare staff.
They also found the vaccine myth alive in one out of ten people.
The two surveys do not clash; P et al. zooms in on parents who saw regression, while E et al. shows the myth is common everywhere.
Together they say the vaccine story is still out there, so you must ask each family what they believe.
Why it matters
If you know a parent links shots to regression you can start with empathy, share clear data, and keep the therapy alliance strong.

03Original abstract
Current research describes a four-category scheme of Autism Spectrum Disorder (ASD) onset: early, regressive, plateau, delay + regression. To replicate prevalence of different onset types, ASD onset (per the Autism Diagnostic Interview--Revised) was examined in a large North American sample; for a subset, parents' causal beliefs were ascertained via the Revised Illness Perception Questionnaire to examine potential associations with ASD-onset types. Onset rates were similar across samples, with a slightly higher proportion of children in the subsample categorized with regression. Top-rated causes of ASD were genetics, brain structure, will of God, toxins in vaccines, and environmental pollution. Parents reporting regression more often believed that toxins in vaccines caused ASD. Influences on treatment selection and broader public-health ramifications are discussed.
