This informant-based rating scale is designed to assist in the assessment of children who have been diagnosed with autism spectrum disorder (ASD).
The ASD-DT is designed to enhance the diagnostic power of the PDDBI. Once a parent or teacher has completed the Extended Form, the ASD-DT allows you to use those scores to complete the branches of a decision tree that ultimately results in a diagnostic category. An algorithm is used to transform PDDBI scores into subgroups of ASD (Atypical ASD, Minimally Verbal ASD, or Verbal ASD) as well as non-ASD subgroups. Intervention suggestions and further recommendations are provided for all subgroups. The ASD-DT is designed to be used with individuals ages 1:6 to 12:5 years. PARiConnect reports will now automatically include the ASD-DT report when appropriate.
This new supplement extends the age range of the PDDBI normative data to age 18:5 years. Ideal for use when monitoring progress over time, this extension to the normative data can be used with both parent and teacher ratings on the PDDBI. The standardization sample includes individuals from a range of racial and ethnic backgrounds and geographic regions. The adolescent normative data are appropriate for use when either the standard or extended items are administered. The new normative data is available on PARiConnect reports.
