Autism can be detected at age 1 year in some (but not all) toddlers Results of the Pierce study (2011) indicated that it is possible to detect some toddlers showing early signs autism and other delays at 12 months using a simple, broad band screening tool (i.e., the CSBS DP IT Checklist) that takes only 5 minutes for a caregiver to complete.
The Modified Checklist for Autism in Toddlers â Revised, with Follow-Up (M-CHATâR/F) â is a free, two-step screening tool used to detect children likely to have autism. It is intended for use at regular well-child checkups for children 16 to 30 months old. With the M-CHAT-R/F, health care providers can classify a childâs risk of having autism as low, medium or high, on the basis of parentsâ answers to 20 questions.
