Objective: This study investigates interrater agreement between clinician ratings using the Rating reference guide developed in Japan for the International Classification of Functioning, Disability and Health (ICF) Rehabilitation Set and patient self-assessments for body function categories of the ICF Rehabilitation Set.
Methods: Eighty-eight inpatients and/or outpatients who received rehabilitation participated in this study. For the assessment of the nine body function categories of the ICF Rehabilitation Set, the patients were asked to complete the self-assessment questionnaires, and the clinicians rated the patients using the Rating reference guide. Interrater agreement between clinicians and patients was investigated using weighted kappa statistics and an intraclass correlation coefficient (ICC (2,1)) to determine interrater agreement of each category and the total score, respectively.
Results: The weighted kappa statistics ranged from 0.58 to 0.87. Eight out of nine categories presented with weighted kappa statistics greater than 0.61. The total score of all categories showed no significant difference between clinicians and patients and presented with an ICC (2,1) of 0.85.
Conclusion: No significant difference was observed between clinician ratings with the Rating reference guide for body function categories and patient self-assessments, showing feasibility of the Rating reference guide as a means of describing the status of patients' functioning.
