Validation of an activity-based data form developed to reflect interventions used by pediatric physical therapists.

PURPOSE The purpose of this study was to validate the Pediatric Physical Therapy Intervention Activities (PPTIA) data form when used by pediatric physical therapists to describe interventions used in the treatment of children with developmental disabilities. The form is based on use of the clinical practice improvement approach. METHODS A panel of 9 experts was assembled to establish face validity for the PPTIA by assessing clarity, accuracy, and relevance. Then, a content validity questionnaire was mailed to a sample of 41 pediatric physical therapists from around the United States to complete after using the PPTIA in clinical practice. RESULTS Seven experts completed and returned the face validity survey and 27 therapists completed the content validity questionnaire. Two revisions to the PPTIA were made based on participant feedback. CONCLUSIONS The overall opinion of the experts and clinicians was that the PPTIA was a valid form for documenting intervention with children.
