Abstract

Psychology Psychology, Developmental Social Sciences
Although symptoms of autism are present early in life and early diagnosis can lead to better outcomes, there is a dearth of validated caregiver-report interviews designed for children under the age of 3 years. We developed the Toddler Autism Symptom Inventory, a semi-structured interview designed to assess the presence and absence of skills and symptoms in children aged 12-36 months. Reliability and validity of items and a cutoff score for likelihood of autism spectrum disorder were established. Specificity and sensitivity of this cutoff were confirmed with a cross-validation sample. The Toddler Autism Symptom Inventory effectively identified most children with autism without excessive false positives. The Toddler Autism Symptom Inventory is a developmentally appropriate caregiver interview for use in diagnostic evaluations of children under age 3 years that offers clearly operationalized diagnostic criteria and a cutoff for autism likelihood for very young children. Lay abstract Determining whether a young child has an autism spectrum disorder requires direct observation of the child and caregiver report of the child's everyday behaviors. There are few interviews for parents that are specifically designed for children under 3 years of age. The Toddler Autism Symptom Inventory is a new interview that asks caregivers of children age 12-36 months about symptoms of possible autism spectrum disorder. The Toddler Autism Symptom Inventory uses a cutoff score to indicate likelihood for autism spectrum disorder; this cutoff score appears to accurately identify most children who are diagnosed with autism spectrum disorder without identifying too many who do not have autism spectrum disorder. The Toddler Autism Symptom Inventory interview can help clinicians to determine whether a young child shows symptoms suggestive of an autism spectrum disorder.
