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.
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.
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).
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.
采用多面Rasch模型分析慢性阻塞性肺疾病（COPD）简明国际功能、残疾和健康分类（ICF）核心集中“活动与参与”部分的信度和效度。
由两名评估者选取103例COPD患者，对其在COPD简明ICF核心集“活动与参与”部分四个类别的能力水平进行评估。采用多面Rasch模型进行数据分析。分析软件使用FACETS（Minifac）3.67.0。
COPD简明ICF核心集的“活动与参与”具有较高的内部一致性（区分指数为5.08，信度为0.96，P<0.05）和良好的评估者间信度（均方拟合统计量范围为0.97 - 1.04，区分指数为0.00，信度为0.00，P>0.05），结构效度良好（均方拟合统计量范围为0.79 - 1.36），各类别测量的一致性较高（区分指数为1.70，信度为0.74）。
COPD简明ICF核心集的“活动与参与”具有良好的信度和效度，可用于测试COPD患者的日常活动。
