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.
