The Pediatric Evaluation of Disability Inventory (PEDI) is a useful clinical and research assessment, but it has limitations in content, age range, and efficiency. The purpose of this article is to describe the development of the item bank for a new computer adaptive testing version of the PEDI (PEDI-CAT). An expanded item set and response options were reviewed by clinician experts and examined at parent and clinician focus groups. Eleven parents participated in 32 cognitive interviews to examine content, format, and comprehension of items and responses. A set of 76 self-care, 78 mobility, and 64 social function items with pictures and a four-point "Difficulty" scale were developed. The PEDI's Caregiver Assistance scale was replaced by a "Responsibility Scale" with 53 items. Content validity was established incorporating input from clinicians and parents. The new item bank covers a broad range of functional activities for children of all ages and abilities.

    • "PEDI-CAT item difficulty estimates were obtained using a large nationally representative sample that included 108 children and youth who received educational services related to ASDs (Haley et al., 2010). Some items were dropped from the initial PEDI-CAT item pool (Dumas et al., 2010) due to excessive variability across respondents (Haley et al., 2010). "

    ABSTRACT: The use of current adaptive behavior measures in practice and research is limited by their length and need for a professional interviewer. There is a need for alternative measures that more efficiently assess adaptive behavior in children and youth with autism spectrum disorders (ASDs). The Pediatric Evaluation of Disability Inventory-Computer Adaptive Test (PEDI-CAT) is a computer-based assessment of a child's ability to perform activities required for personal self-sufficiency and engagement in the community. This study evaluated the applicability, representativeness, and comprehensiveness of the Daily Activity, Social/Cognitive, and Responsibility domains for children and youth with an ASD. Twenty professionals and 18 parents provided feedback via in-person or virtual focus groups and cognitive interviews. Items were perceived to represent relevant functional activities within each domain. Child factors and assessment characteristics influenced parents' ratings. In response to feedback, 15 items and additional directions were added to ensure the PEDI-CAT is a meaningful measure when used with this population.

    ABSTRACT: The purpose of this article is to review the innovations, applications, and effect of the original Pediatric Evaluation of Disability Inventory (PEDI) published in 1992 and to describe planned revisions. During the past decade, the PEDI has helped to shift thinking from a developmental to a functional focus. Using the PEDI, researchers and clinicians worldwide have highlighted variations in functional skill acquisition in clinical populations, the importance of recognizing cultural differences, and the value of documenting functional progress in relation to interventions. The PEDI has had a rich tradition in helping to document functional development. New methods are proposed for the next generation of the PEDI by using item banks and computer adaptive testing. RECOMMENDATIONS FOR CLINICAL PRACTICE: The computer adaptive testing feature and the revised and expanded content of the new PEDI will enable therapists to more efficiently assess children's functioning to a broader age group of children.

    ABSTRACT: The PEDI-CAT is a new computer adaptive test (CAT)version of the Pediatric Evaluation of Disability Inventory(PEDI). Additional PEDI-CAT items specific to post acute pediatric hospital care were recently developed using expert reviews and cognitive interviewing techniques.Expert reviews established face and construct validity,providing positive feedback on domain content and response scale options. Cognitive interviews established content validity while 60% of items were revised or removed because of the items being unclear or ambiguous, not measuring what was intended or lack of therapeutic terminology. As a result, an item bank containing more than 110 items in the three domains of self-care, mobility, and social function has been constructed and is ready to be calibrated and tested in a CAT application. With the addition of items specific for an inpatient pediatric postacute hospital setting, the PEDI-CAT (postacute hospital) will provide clinicians with the opportunity to use a context-specific assessment of function to support quality evaluations during inpatient rehabilitation care.
