ABSTRACT

Objective:To explore the reliability and validity of the International Classification of Functioning, Disability and Health′s 17-item Rehabilitation Set (ICF-RS-17) when used to evaluate multidisciplinary inpatients.Methods:A total of 359 inpatients in the departments of rehabilitation, orthopedics, neurology, and neurosurgery of three hospitals in Jiangsu province were assessed with the ICF-RS-17 at admission and at discharge, and the internal consistency of the tool was calculated. Inter-rater and intra-rater reliability were quantified using interclass correlation coefficients (ICCs). Structural validity was analyzed using factor analysis.Results:The tool′s Cronbach′s α was 0.945. The overall inter-rater ICC was 0.946 with the ICCs of all of the items except b280 sensation of pain within the range from 0.630 to 0.948. The overall intra-rater ICCs ranged from 0.471 to 0.947. The factor analysis found three factors with eigenvalues greater than 1, accounting for 74% of the variation, without double-loaded items. The three influential factors were exercise ability, sleep perception communication ability and self-care ability.Conclusion:The ICF-RS-17 has good internal consistency, inter-rater and intra-rater reliability and structural validity in the evaluation of multidisciplinary inpatients.
