Feasibility of the International Classification of Functioning, Disability and Health Rehabilitation Set for inpatient rehabilitation: Selection and validity of a set of categories for inpatients in a convalescent rehabilitation ward. Jpn J Compr Rehabil Sci 2020; 11: 1-8.
Objective: To evaluate the feasibility of the International Classification of Functioning, Disability and Health (ICF) Rehabilitation Set for inpatients in a convalescent (Kaifukuki) rehabilitation ward.
Methods: Overall, 295 inpatients in convalescent rehabilitation wards were rated using the ICF Rehabilitation Set, and the proportion of missing values was investigated. Categories with missing values <10% were selected, and internal construct validity of the total score of the selected categories was examined using Rasch analysis.
Results: Missing values were detected in 25 items, of which seven had missing values of ≥10%. No ceiling or floor effects were noted. Rasch analysis of 23 categories with missing values <10% showed a good fit to the model after applying testlet solution and item splitting, which supported the internal construct validity of the ICF Rehabilitation Set.
Conclusion: This identified the set of categories of the ICF Rehabilitation Set that could be used for evaluating rehabilitation inpatients. These categories had good internal construct validity based on Rasch analysis.
