Abstract

Funahashi R, Mukaino M, Otaka Y, Senju Y, Yoneda C, Ozeki Y, Shimizu Y, Koike T, Saito E. 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.

Keywords: ICF; ICF Rehabilitation Set; Rasch analysis; convalescent rehabilitation.
