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; reproduction, 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 manuscript reporting reliability and validity for this instrument is currently under review for publication in a scientific journal. When published, a link to the publication will be posted here. Given the pressing needs for remote diagnostic procedures presented by the COVID-19 pandemic, we are posting the measure here and hope it can be helpful for clinicians, who are permitted to use it with the understanding that the validation study has not yet been accepted by a scientific journal.
