What is the PDDBI?
The PDDBI is an informant-based rating scale, designed to assist in the assessment (for problem behaviors, social, language and learning/memory skills) of children who have been diagnosed with Autism Spectrum Disorder (ASD). The PDDBI provides age-standardized scores for parent and teacher ratings. It is applicable for ages two through 18.5 years.
Why is the PDDBI used?
TRICARE has selected the PDDBI as it focuses on the core deficits of ASD based on the DSM-5 criteria. This measure allows for an understanding of where a person falls within the spectrum of autism and the level of impact of symptoms.
Problem behaviors measured via the PDDBI include stereotyped behaviors, fears, aggression, social interaction deficits, and aberrant language associated with children with PDD having lower or high-functioning skills. Two forms for the teacher and parent consist of six domains (the extended forms measure 10 domains): Approach/Withdrawal Problems, Sensory/Perceptual Approach, Ritualisms/Resistance to Change, Social Pragmatic Problems, Semantic Pragmatic Problems, Arousal Regulation Problems (extended form), Specific Fears (extended form), Aggressiveness (extended form), Receptive/Expressive Social Communication Abilities, Social Approach Behaviors, Expressive Language, Learning, Memory, and Receptive Language (extended form). Each item is rated on a Likert scale, from “Never” to “Often/Typically.”
What are the PDDBI submission requirements?
At baseline, only the PDDBI parent form is required. Each authorization request thereafter will require both the parent and the teacher form. The name of the person completing the form and their relation to the beneficiary must be included. The ABA supervisor must complete the teacher form and cannot be delegated. All domains must be included, as well as the composite T-scores and the total autism composite score. The full publisher print report or hand-scored protocols are required. The scores cannot be imbedded within the treatment plan or any other clinical documents.
How do ABA providers use PDDBI scores?
The PDDBI scores are used to help develop the treatment plan and track progress.
When do PDDBI scores indicate the need for modification of the treatment plan?
The treatment plan may need to be modified during the six-month review if the beneficiary has made limited progress, has shown signs of regression, or met targeted goals.
