Lay beliefs about autism spectrum disorder among the general public and childcare providers.
One in ten people still believe vaccines cause autism—use short videos and direct questions to swap myth for fact.
01Research in Context
What this study did
Austin et al. (2015) asked the adults and 200 childcare workers what they know about autism. They used a short true-or-false quiz and a few open questions.
The team wanted to see which myths still live on and whether daycare staff know more than the average person.
What they found
Most people got the basics right, but one in ten still blame vaccines. Many also missed core traits like social differences.
Childcare staff scored only a little higher than the public. The vaccine myth stayed strong in both groups.
How this fits with other research
Kocher et al. (2015) ran a near-copy survey the same year. They found parents who saw skill loss in their child were the ones most likely to name vaccines. This backs the vaccine number E et al. saw.
Whaling et al. (2025) asked college students to label autistic behaviors. Only 13 percent said "autism"; most picked ADHD or bad parenting. Together with E et al., this shows the public both believes the wrong cause and misses the real signs.
Nah et al. (2024) tested a 5-minute animated video. Knowledge rose right away, proving media can fix the myths E et al. found.
Why it matters
You will meet parents and teachers who still link shots to autism. Start every intake by asking, "What do you think caused your child's autism?" If you hear "vaccines," you have science-based talking points ready. Share the short animated clips Yong-Hwee et al. used; they work in under five minutes. Quick media drops can clear myths before they shape treatment choices.

03Original abstract
We conducted a survey of beliefs about autism among the general public in the United States and Canada (n = 823) and among individuals working in childcare facilities in the state of Idaho (n = 176). Results included the following. Almost all respondents correctly believed that autism's primary causes are genetic and neurological (not parenting, drugs, or current diet), that it can be identified in early childhood, and that helpful interventions exist. Respondents generally distinguished diagnostic from non-diagnostic traits, but approximately half incorrectly labeled constant squirming as diagnostic and difficulties in making friends as non-diagnostic. College graduates and childcare workers were more likely to have learned about autism in professional/academic settings and to correctly recognize diagnostic traits. Of concern, 10% of respondents considered vaccinations to be among the two main causes of autism. Accurate public understanding of autism spectrum disorders can facilitate early identification and effective intervention; our results suggest that efficient channels for conveying accurate information include broadcast and online media (from which the general public, especially members of ethnic minority groups, were most likely to learn about autism), and professional development courses for childcare providers.
