简明版骨质疏松国际功能、残疾和健康分类核心分类组合的信效度研究

A study on the reliability and validity of International Classification of Functioning and Disability and Health(ICF) brief core sets for osteoporosis

目的:探讨简明版骨质疏松国际功能、残疾和健康(ICF)核心分类组合的信度和效度。方法:122例骨质疏松症患者进行简明版骨质疏松ICF核心分类组合和欧洲骨质疏松症基金会生活质量问卷(QUALEFFO-41)评定。信度研究采用重测信度、观察者间信度和内部一致性信度,效度研究采用效标效度、结构效度和内容效度。重测信度和观察者间信度检验采用组内相关系数(ICC);内部一致性检验采用Cronbachα值分析;效标效度用Spearman相关;内容效度应用德尔菲法;结构效度采用因子分析法。结果:(1)信度:重测信度ICC 0.762—0.921;观察者间信度ICC 0.781—0.941;内部一致性信度Cronbachα系数0.953。(2)效度:校标效度:简明版骨质疏松ICF核心分类组合中功能和残疾部分总分与QUALEFFO-41总分呈中度相关(r=0.654);内容效度:经德尔菲法确定内容效度好;结构效度:公因子1包括条目d430、d450和d920,公因子2包括条目b710、b730、s750、s760,公因子3包括条目e110、e355、e580,公因子4包括条目b152、b280。结论:简明版骨质疏松ICF核心分类组合的信度、校标效度和内容效度较好。除b710和b730、s750和s760归为同一维度外,其余条目的结构效度与目前ICF成分结构一致。

Objective： To examine the reliability and validity of International Classification of Functioning and Disability and Health （ICF） brief core sets for osteoporosis. Method： One hundred and twenty-two patients with osteoporosis were involved in this study. The functional evaluation were assessed by ICF brief core sets for osteoporosis and Quality of Life Questionnaire of the Euro- pean Foundation for Osteoporosis （QUALEFFO-41）. The test-retest reliability, inter-rater reliability and internal consistency reliability were analyzed using intraclass correlation coefficient （ICC） and Cronbach＇s u coefficients. The criterion validity was analyzed with Spearman rank correlation coefficients. The content validity was as- sessed through Delphi exercise. The construct validity was evaluated by factor analysis. Result： The ICC of the test-retest reliability was 0.762-0.921. The ICC of the inter-rater reliability was 0.781-0.941. The internal consistency reliability of the ICF brief core sets was good with Cronbach＇s alphas of 0.953. A moderate positive correlation was found between the ICF components of body structure, function, activity and participation and QUALEFFO-41 （r=0.654）. With Delphi exercise, the content validity of ICF was good. Factor analysis revealed that d710 and d730 were categorized with s750 and s760 in a same component,while the construct validity of other items were good as expected. Conclusion： The reliability, criterion validity, and content validity of the ICF brief core sets for osteoporosis are good. Except that b710 and b730 are categorized with s750 and s760 in a same component, the construct validity of other items is good as expected.
