“The Pediatric Evaluation of Disability Inventory (PEDI), originally published in 1992, has been revised as a computer adaptive test (CAT)-the PEDI-CAT.  The PEDI-CAT measures abilities in the three functional domains of Daily Activities, Mobility and Social/Cognitive.  The PEDI-CAT can be used across all clinical diagnoses and community settings.  As with the original paper-pencil PEDI, the PEDI-CAT can be administered by professional judgment of clinicians or educators who are familiar with the child or by parent report. This computerized adaptive version of the PEDI is intended to provide an accurate and precise assessment while increasing efficiency and reducing respondent burden……………..” www.pedicat.com

    A colleague (Orli Weisser-Pike) and I were working on designing a study of children with cortical visual impairment, and we were considering using the latest version of the PEDI-CAT as one of our outcome measures. We entered a “practice” child in the iPad and proceeded through the assessment, and it did not appear to be working as we expected. That is, although we entered the birthdate for a child who was 6 months or so old, it gave us much higher level questions to answer—ones that really did not make sense at all for a 6-month-old. We were not able to troubleshoot and determine where we went wrong, so I’m reaching out to you for any thoughts you might have or to find out whether there is someone in particular we should contact who could help us? Thank you!

    Hi Anita,
    I am not sure which domain you selected or which version (Speedy vs. Content-Balanced)you tested. Each domain starts with a question that is in the middle of the scale. So for example, for the mobility domain, the first question is “Stands for a few minutes”. If you answer unable for a 6 month old, then you will get an easier question “sits with support of pillow” and then “when lying on belly pushes up on elbows”, and “turns head from side to side”. As you get closer to the score you will get harder items that you will respond unable so that the scoring algorithm can get the most accurate score.
    If you selected content-balanced, then you will most likely get some irrelevant questions for a young child whose skills will tend to be at the low end of the scale due to age.
    For the Content-Balanced assessment, the algorithm requires that a certain number of items be asked in each content area. If almost all other items in a content area have been asked, the program will be forced to ask whatever items remain, including some that may seem less relevant based on a child’s age. Please let me know if that answers your questions or if you have additional questions.
