Informant-based Rating Scale Designed to Assist in the Assessment of Children Who Have Been Diagnosed with Autism Spectrum Disorder (ASD)

 

The PDDBI was developed with several primary goals in mind:

  • To provide an assessment of autism that results in age-standardized scores.
  • To create items that measure both problem behaviors and social communication skills relevant to autism.
  • To include separate inventories for parents and teachers, in order to address the issue of generalization.
  • To include a measurement system (i.e., Likert scaling) that has been shown to be useful in measuring responsiveness to intervention and/or detecting change.
  • To create an assessment tool that would be sensitive to, and useful for, multiple applications (e.g., clinical, medical, school, research).

Now available

The PDDBI Score Report has been enhanced. Updates include a new interpretive guidance section, a revised look and feel with clear icons indicating score ranges, and an optional items and responses section.

 

Features and benefits

  • Unlike existing assessments for ASD, the PDDBI was developed to assess both problem behaviors as well as appropriate social, language, and learning/memory skills.
  • Applicable in school, clinical, and research applications.
  • Use the PDDBI for assessment, treatment planning, and treatment monitoring.
  • The PDDBI (along with the SIPA, PSI-4-SF, and SRS-2) meet the requirements for ABA therapists working with autism patients who have federal health insurance (i.e., TRICARE).
  • Age-standardized scores for parent and teacher ratings are provided in a new score report that more clearly indicates score ranges and provides items and responses organized by domain.
  • A Spanish translation of the parent form is available.

Additional components

PDDBI Professional Manual Supplement: Autism Spectrum Disorder Decision Tree (ASD-DT)

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 automatically include the ASD-DT report when appropriate.

PDDBI Professional Manual Supplement: Adolescent Normative Data

This 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 normative data are available on PARiConnect reports.

Supplemental material from PDDBI author Ira L. Cohen explains how to use the Autism Spectrum Disorder Decision Tree with the PDDBI for screening and intervention planning. A second white paper explains the creation and use of the new Spanish translation of the PDDBI Parent Form. Visit the Resources tab above to view or download.
