PMID 38713266WHAT IT FOUND
Autistic adults reported greater difficulty predicting daily events than non-autistic adults, and these self-reports matched their performance on rhythm tasks.
A new 19-item questionnaire captures these prediction challenges across social, sensory, and motor domains.
Key findings
01Autistic adults scored significantly lower on the questionnaire than non-autistic adults, indicating greater self-reported prediction difficulties.
02Self-reported prediction scores correlated with actual performance on tapping tasks, where less precise tapping was associated with lower self-reported prediction skills.
03Social prediction items were consistently harder for participants to endorse than motor or sensory items.

What it does not show
The questionnaire is not yet validated for tracking changes over time or for using sub-scores for specific domains like social or motor separately. The study did not collect data on race or ethnicity, so it is unclear if the results apply to diverse populations. The expert panel that designed the items was largely from one institution and invested in the theory that prediction is a key deficit in autism, which may have influenced the wording of the questions. Self-report scores may be influenced by executive functioning or working memory, which were not measured.
Declared interests
The study was funded by the Massachusetts Institute of Technology. The authors included researchers from the same institution who developed the theoretical framework being tested.
The easy way to misread this
Do not use this questionnaire to diagnose autism or to track progress in therapy. It is not validated for these purposes, and the authors explicitly state it is not sensitive to change over time.
