To examine the discriminant validity, test-retest reliability, administration time and acceptability of the pediatric evaluation of disability inventory computer adaptive test (PEDI-CAT).
A sample of 102 parents of children 3 through 20 years of age with (n = 50) and without (n = 52) disabilities was recruited for this prospective field study. A sub-sample (n = 25) also completed the PEDI-CAT a second time within one month. Parents completed 15 items in each of the four PEDI-CAT domains (daily activities, mobility, social/cognitive, responsibility) using a laptop computer. Following completion, parents answered a four-question user evaluation survey.
PEDI-CAT scores based on parent responses differentiated between groups of children with and without disabilities in all four domains. Test-retest reliability estimates were high (ICC = 0.96-0.99) for all four domains. The mean time to complete 60 items for the full sample (n = 102) was 12.66 minutes (SD = 4.47). Parents reported favorable reactions to the PEDI-CAT.
The PEDI-CAT offers a valid and reliable assessment acceptable to parents.

    • "Specifically, the PEDI-CAT Social/Cognitive Domain addresses communication, interaction, safety, behavior, play, attention and problem-solving skills. The PEDI-CAT is a valid, norm-referenced measure which provides both normative and scaled scores for each domain (Dumas and Fragala-Pinkham, 2012; Dumas et al, 2012; Haley et al, 2011). It was used in this study to provide a description of the participants' functional skills. "

    ABSTRACT: Purpose: The primary purpose of this pilot study was to evaluate the effectiveness of a14-week aquatic exercise program on gross motor function and walking endurance in children with cerebral palsy (CP). The secondary purpose was to evaluate changes in functional strength, aerobic capacity and balance. Method: A prospective time series group design consisting of four measurement sessions (two baseline, one post intervention, and 1-month follow-up) was used. Eight ambulatory children ages 6-15 years with CP and classified at Gross Motor Function Classification System Level I or Level III participated in an aquatic aerobic exercise program. Results: Significant improvements were observed for the primary outcomes of gross motor function and walking endurance. No significant differences between any of the secondary measures were observed, although all of the measures demonstrated trends of improvement after intervention. Conclusion: Ambulatory children with CP may improve their gross motor skills and walking endurance after an aquatic exercise program held twice per week for 14 weeks, utilizing moderate-to-vigorous exercise intensity and consisting of functional activities.

    ABSTRACT: To evaluate the effectiveness of a 14-week aquatic exercise programme for children with autism spectrum disorders (ASD). Design: Non-randomized control trial. Twelve children participated in this pilot study with seven participants in the aquatic exercise group and five in the control group. The programme was held twice per week for 40 minutes per session. Swimming skills, cardiorespiratory endurance, muscular endurance, mobility skills and participant and parent satisfaction were measured before and after the intervention. No significant between-group changes were found. Within-group improvements for swimming skills were found for the intervention group. Programme attendance was high. Parents and children were very satisfied with the programme activities and instructors. This pilot programme was feasible and showed potential for improving swimming ability in children with ASD. Exercise intensity was low for some participants, most likely contributing to a lack of significant findings on fitness outcomes.

    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.
