Thank you for your interest in taking the ChatterBaby™ surveys. Your data will be confidentially stored and applied to research to help children and families all over the world, by improving our understanding of risk factors for autism and related disorders.  If you are concerned about your child’s behaviors for autism or a related disorder, we encourage you to take our free screening surveys described below. 

Only your doctor can diagnose your child with autism. If your child scores unexpectedly high, we recommend you speak with your doctor about the need for further diagnostic testing.

CDC Milestone Checklist at 1 Year

How your child plays, learns, speaks, acts, and moves offer important clues about your child's development. Developmental milestones are things most children can do by a certain age. This survey collects information regarding your baby’s development by a week before or after their first birthday.  Please answer each question as it applies to your baby within the week before or after your baby's first birthday.

Please answer every question and give the most accurate answer you can. We are not looking for any particular answer. We just want to know how your baby behaves and responds in various ways.

This survey does not predict autism risk, but it does question many behaviors or delays which may be seen in children who are at risk for developmental delays.

Quantitative CHecklist for Autism in Toddlers

The Q-CHAT is a measure of autism risk in toddlers (18 months- 3 years) but does not actually diagnose a child with autism. It is scored out of 100 points. The closer you get to 100, the higher the risk of autism. 

There is no diagnostic cut-off for the Q-CHAT, similar to how being overweight does not guarantee one to have diabetes. In one study, typically developing children usually scored between 19-35 on the Q-CHAT, while children who developed Autism Spectrum Disorder usually scored between 38-66. However, the "typical" score depends on the baby's gender (boys score higher), age, and nationality. 

If you have concerns about your child's development, please discuss them further with your doctor.

Childhood Autism  Spectrum Test

Formally known as the Childhood Asperger Syndrome Test, the CAST is a parental questionnaire to screen for autism spectrum conditions in children ages 4-11.  Upon completion of this survey, you will receive your child’s risk score for Autism Spectrum Disorder, scored out of a total of 31 points. For this test, a score greater than 15 indicates an increased risk for autism spectrum disorder.  A higher CAST score does not diagnose a child with autism but does indicate that the child should be screened further.

Please discuss any additional concerns with your child's doctor.
