Evaluations and Assessments

Autism Evaluations

Tucson Alliance for Autism (TAFA) provides gold standard assessment of Autism Spectrum Disorder (ASD). The evaluation procedure includes the Autism Diagnostic Observation Schedule: Second Edition. The ADOS-2 as an evaluation tool has the highest sensitivity and specificity to an ASD diagnosis when administered by trained and reliable professionals according to Goldstein & Azonoff 2018, current experts in the field. This is a standardized instrument aligned with diagnostic criteria set by American Psychiatric Association and an interactive assessment in which the evaluator works directly with the client. The Autism Diagnostic Interview-Revised is another tool used by the TAFA evaluation team critical to a comprehensive evaluation of ASD. This interview tool, also aligned with diagnostic criteria set by the American Psychiatric Association, is a comprehensive caregiver interview targeting current and past behaviors characteristic of ASD. Goldstein and Azonoff emphasize that it is insufficient to allow the caregiver to respond to a list of characteristics of ASD as a means of making a diagnosis.

By including the ADOS-2 and ADI-R both administered by trained evaluators who have greater than 40 years combined experience in the assessment of ASD allows for a careful and comprehensive evaluation of TAFA clients.
