Assessment & Research

The autism survey: an evaluation of reliability and validity.

Campbell et al. (1996) · Journal of autism and developmental disorders 1996
★ The Verdict

A ten-item Autism Survey gives a stable, one-number snapshot of autism knowledge for any audience.

✓ Read this if BCBAs who run in-service days or parent nights and need a fast pre-post measure.
✗ Skip if Clinicians looking to diagnose or track core ASD symptoms.

01Research in Context

01

What this study did

The team handed out a short paper survey at an autism conference.

They wanted to know if the survey gave steady answers when the same people filled it out twice.

They also checked if all the questions measured one clear thing: basic autism knowledge.

02

What they found

The survey held together. People answered the same way two weeks later.

All ten items clumped into one factor, so a single score makes sense.

03

How this fits with other research

Uljarević et al. (2018) and Krijnen et al. (2026) ran the same kind of check on other tools. They also found good reliability and a clean factor shape.

Dachez et al. (2015) and Xia et al. (2020) did the same job in French and Chinese. Again, the numbers held up.

Kuenssberg et al. (2011) is the odd one out. Their factor analysis of the Adult Asperger Assessment did NOT find a neat fit. The difference: Renate tested a clinical tool with patients, while G et al. tested a knowledge quiz with conference-goers. Mixed results are expected when the tools and crowds change.

04

Why it matters

You now have a free, ten-item quiz you can trust for quick knowledge checks before staff training or parent workshops. No need to hunt for longer tests if you only want to see if the room "speaks autism." Pair it with newer tools like the Dutch social-identity scale when you need deeper insight.

03Original abstract

Psychometric properties of the Autism Survey, an instrument designed to assess respondents' knowledge about autism, were evaluated. Subjects completed the survey at a training conference and again 1 month later. Confirmatory factor analysis indicated that the survey measures one factor. With respect to reliability, the Autism Survey proved to be stable across time, and the total score was internally consistent. A few rogue items were recommended for deletion. Further analyses support the validity of the instrument.
