The Q-CHAT is a normally distributed quantitative measure of autistic traits in children 18-24 months old. It is the first ASC screening instrument, designed for use with toddlers, that has been shown to produce a range of scores that approximates to a normal distribution.

Please answer the following questions about your child:

  1. Does your child look at you when you call his/her name?
  2. How easy is it for you to get eye contact with your child?
  3. When your child is playing alone, does s/he line objects up?
  4. Can other people easily understand your child’s speech?
  5. Does your child point to indicate that s/he wants something (e.g. a toy that is out of reach)?
  6. Does your child point to share interest with you (e.g. pointing at an interesting sight)?
