Abstract

Purpose: To analyze the reliability and validity of the "activity and participation" component of the brief international classification of functioning, disability and health (ICF) core set for chronic obstructive pulmonary disease (COPD) using a Multi-faceted Rasch model.

Patients and methods: A total of 103 patients with COPD were selected by two raters to evaluate their ability levels in the four categories of the "activity and participation" component of brief ICF core set for COPD. The Multi-faceted Rasch model was used for data analysis. The analysis software used FACETS (Minifac) 3.67.0.

Results: The "activity and participation" of brief ICF core set for COPD had a high internal consistency (separation index of 5.08, reliability of 0.96, P <0.05) and good inter-rater reliability (mean-square fit statistic range was 0.97-1.04, the separation index was 0.00, the reliability was 0.00, P >0.05), the construct validity was good (mean-square fit statistic range was 0.79-1.36), and the consistency of each category measurement was high (the separation index was 1.70, the reliability was 0.74).

Conclusion: The "activity and participation" of brief ICF core set for COPD has good reliability and validity, which can be used to test the daily activities of patients with COPD.

Keywords: Multi-faceted Rasch model; chronic obstructive pulmonary disease; disability and health; reliability; the international classification of functioning; validity.
