Description

The PDDBI is an informant-based rating scale that is designed to assist in the assessment of children who have been diagnosed with Autism Spectrum Disorder (ASD). PDD is characterised by severe and pervasive impairments in several areas of development (e.g. communication skills, reciprocal social interaction skills, presence of stereotypic behaviours/activities). Unlike existing assessments for autism/PDD, the PDDBI was developed to assess both problem behaviours as well as appropriate social, language, and learning/memory skills. It also was designed to provide age-standardised scores for both parent and teacher ratings.

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 behaviours 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).

Features and benefits

• Unlike existing assessments for ASD, the PDDBI was developed to assess both problem behaviours 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.
• Sophisticated, statistically driven reports identify differences between parent and teacher raters and measure change over time.
  • A new multirater report highlights statistically significant differences between parent and teacher ratings to identify inconsistencies in behaviors across settings.
  • A new progress monitoring report identifies statistically significant treatment gains or worsening behaviors over time.
  • Access both reports for free in PARiConnect once you purchase a Score Report.
• Screen for autism in children, in 10 minutes, with the PDD Behavior Inventory Screening Version (PDDBI-SV).

PDDBI Professional Manual Supplement: Advanced Score, Multirater, and Progress Monitoring Interpretation

This new supplement provides new guidance for calculation and interpretation of parent–teacher rating comparisons and tracking changes in scores over time, using Reliable Change Indices. In addition, it includes guidance for advanced interpretation of the PDDBI, from interpreting individual scores and clusters to comparing parent and teacher ratings and tracking scores over time. This manual supplement applies to ages 1:6 to 18:5 years.
