Abstract
Objective: The aim of this study was to examine the psychometric properties(reliability and validity)of the Participation and Environment Measure for Children and Youth(PEM-CY)in children with mobility limitations.
Methods: Parents of 261 children with disabilities were included in a questionnaire survey of their children's age, grade, disease, gross motor function, and PEM-CY. Cronbach's α for internal consistency and ICC(3.1)for retest reliability were calculated and examined. Validity was examined by calculating the main effect by performing a two-way analysis of variance with two factors of motor function limitation and age.
RESULTS: 134 letters were used with valid data; Cronbach's α was greater than or equal to 0.6 for all items; ICC(3.1)was greater than or equal to 0.7 for all items. Analysis of variance revealed significant effects and small-large effect sizes(0.00-0.32)for many items in motor function limitation. For age, no significant effects were identified for many items, with effect sizes ranging from small to medium(0.00-0.04).
CONCLUSION: PEM-CY has moderate to high internal consistency, high retest reliability, and small to large validity in children with mobility limitations and can be used in clinical and research settings.
