(PDDBI) PDD Behavior Inventory
BY IRA L. COHEN, PHD, AND VICKI SUDHALTER, PHD
The PDDBI tells you how children are functioning in areas typically affected by PDD—communication, reciprocal social interaction, ritualistic activities, and learning skills.
The test is composed of Teacher and Parent Rating Forms, each provided in standard and extended formats on a single protocol—so you can decide which to use in a given situation. While the standard forms cover six domains, the extended forms measure 10 domains in two broad categories:
- Sensory/Perceptual Approach
- Ritualisms/Resistance to Change
- Social Pragmatic Problems
- Semantic Pragmatic Problems
- Arousal Regulation Problems
- Specific Fears
Receptive/Expressive Social Communication Abilities
- Social Approach Behaviors
- Expressive Language
- Learning, Memory, and Receptive Language
Test results are useful in planning treatment, monitoring progress, assessing outcome, and making placement decisions.
New! 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 will now automatically include the ASD-DT report when appropriate.
New! PDDBI Professional Manual Supplement: Adolescent Normative Data
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.
