Abstract

The PDD Behavior Inventory (PDDBI) is a rating scale filled out by caregivers or teachers that was designed to assess children having a Pervasive Developmental Disorder (PDD; autism, Asperger disorder, PDD-NOS, or childhood disintegrative disorder). Both adaptive and maladaptive behaviors are assessed in the scale, making it useful for treatment studies in which decreases in maladaptive behaviors and improvements in adaptive social and language skills relevant to PDD are expected. The adaptive behaviors assessed include core features of the disorder such as joint attention skills, pretend play, and referential gesture. The maladaptive behaviors sample a wide variety of behaviors observed in both lower- and higher-functioning individuals and include stereotyped behaviors, fears, aggression, social interaction deficits, and aberrant language. The inventory was found to have a high degree of internal consistency. Inter-rater reliability was better for adaptive behaviors than for maladaptive behaviors. Factor analyses confirmed the structure of the PDDBI and indicated good construct validity. In a subsample of children between 3 and 6 years of age, raw scores for adaptive behaviors increased with age in the parent and teacher versions, as did measures of social pragmatic problems. It was concluded that the PDDBI is both reliable and valid and is useful in providing information not typically available in most instruments used to assess children with PDD.

An Intervention for Sensory Difficulties in Children with Autism: A Randomized Trial

“…Pervasive Developmental Disorders Behavior Inventory (PDDBI): The PDDBI (Cohen et al 2003) is a standardized assessment normed on children with autism or PDD between the ages of 18 months and 12 years, 5 months. This assessment evaluates the severity of a child’s autism behaviors on a number of parent-reported domains.…”

Nutritional and metabolic status of children with autism vs. neurotypical children, and the association with autism severity

“…Three tools were used to assess the severity and symptoms of autism, namely the Pervasive Development Disorder Behavior Inventory (PDD-BI) [35], Autism Evaluation Treatment Checklist (ATEC) [36] and Severity of Autism Scale (SAS) [37]. For the PDD-BI, a modified Autism Composite was used, following the example of a previous study [37].…”

The association between self-injurious behaviors and autism spectrum disorders

“…Examples of measures assess the frequency and/or severity (generally using a Likert-type scale of “not a problem” to a “severe problem”) of a variety of challenging behaviors (ie, not just SIB) include the Aberrant Behavior Checklist,48 Behavior Problems Inventory-01,49 Children’s Scale of Hostility and Aggression: Reactive/Proactive,50 Developmental Behavior Checklist,51 and Nisonger Child Behavior Rating Form 52. Similarly, there are a few measures which specifically address the range of behavioral concerns exclusively in those with ASD including the PDD Behavior Inventory,53 Autism Spectrum Disorder – Behavior Problems for Adults,54 Autism Spectrum Disorders – Behavior Problems for Children,55 and the Baby and Infant Screen for Children with aUtIsm Traits (BISCUIT)-Part 3 56. Outcomes of these measures generally refect a score on a behavioral subdomain (eg, self-injury, stereotypy, aggression), which are then used to determine an overall score when compared to data from a normative sample.…”
