About IASQ

IASQ is a brief caregiver-report autism screen with 10 yes or no items. It was developed from the Indian Scale for Assessment of Autism and validated for ages 3 to 18. A positive screen at a cutoff of 1 yes showed very high sensitivity and moderate specificity in studies. You can set a stricter cutoff for more specificity if needed.

Items are public domain as published in PLOS ONE. No endorsement is implied.
