The Content Validity and Inter-Rater Reliability of the Occupational Therapy Pediatric Inventory of Cognitive Skills (OT-PICS): An Assessment Tool of Functional Cognition in Children.

The Occupational Therapy Pediatric Inventory of Cognitive Skills (OT-PICS) is being developed to evaluate functional cognition skills in children in the domains of play, educational participation, and self-care. This study aimed to determine the content validity and inter-rater reliability of the OT-PICS. Seven content experts agreed that all 15 items of the tool are essential items to examine functional cognition in children (k = 0.71-1.0; I-CVI = 0.71-1.0; S-CVI = 0.96. The OT-PICS also has moderate reliability (ICC = 0.63) between nine trained raters. The tool was then revised and refined for clarity based on therapist's comments and feedback.
