Therapists found the Pediatric Evaluation Disability Inventory-Patient Reported Outcome (PEDI-PRO) score report useful, though additional training on advanced item-response theory (IRT) concepts may be needed for accurate interpretation.
Area of Science:
- Rehabilitation Medicine
- Clinical Assessment
- Health Informatics
Background:
- Effective score reports are crucial for therapists to accurately interpret patient assessments.
- The Pediatric Evaluation Disability Inventory-Patient Reported Outcome (PEDI-PRO) is a key assessment tool.
Purpose of the Study:
- To evaluate the accuracy of occupational and physical therapists' (OT, PT) interpretation of item-response theory (IRT)-based PEDI-PRO results using a pilot score report.
- To assess the perceived clinical utility of the PEDI-PRO pilot score report among therapists.
Main Methods:
- An exploratory, sequential mixed methods design was employed.
- Focus groups with 20 OTs and PTs informed score report development, followed by a survey with 33 OTs and PTs who reviewed fictional client reports and answered interpretation and utility questions.
Main Results:
- Visual cues in the score report aided interpretation, but therapists desired more explanation for advanced IRT concepts.
- Therapists accurately interpreted basic IRT concepts but struggled with advanced ones like fit and unexpected responses.
- Therapists identified specific report components for sharing with families, clinicians, and payers.
Conclusions:
- The pilot PEDI-PRO score report received high endorsement from therapists.
- Additional training may be necessary for therapists to fully interpret advanced item-response theory (IRT) concepts within the PEDI-PRO score report.

Guidelines for Writing Outcome
Patient outcomes reflect the patient's response to the goal rather than what the nurse aims to achieve. Terminology should be observable and measurable to avoid the reader's interpretation. The desired outcome should be realistic and achievable in the designated care timeframe. Expected outcomes should align with adjunctive therapies. The outcome should enhance care...
Pulmonary Function Tests
Pulmonary Function Tests are crucial diagnostic tools for assessing respiratory function, particularly in patients with chronic respiratory disorders. They comprehensively evaluate lung volumes, ventilatory function, breathing mechanics, diffusion, and gas exchange. These tests help diagnose pulmonary diseases and play a significant role in monitoring disease progression, evaluating disability, and assessing response to therapy.
