The Toddler Autism Symptom Inventory (TASI) is a semi-structured interview designed for use in developmental evaluations of children age 12-36 months. The TASI interview should be used in conjunction with other sources of information, including direct observation and a thorough developmental history.
The TASI interview, manual, and scoring tool can be downloaded here for free. These documents are copyrighted; modification or revisions of these materials is not permitted without a written agreement with the authors. The TASI authors can be reached at TASIinterview@gmail.com
The TASI is a measure used by trained clinicians in the diagnosis of autism. However, it is not designed to pick up every child, and may mis-identify some children; if you have concerns about your child’s development, talk to your pediatrician.
