基于ICF的失能评估工具在临床应用中的信度研究

目的验证基于国际功能、残疾和健康分类(ICF)的功能评定工具在失能评估中的信度。方法选取江苏钟山老年康复医院存在功能障碍的住院患者371例参与本研究,以基于ICF的功能评定工具对患者进行失能评估,以数字化评定量表(0~10分)评估条目失能程度。分析失能评定工具的内在一致性、评估者间信度、评估者内信度。结果基于ICF的失能评定量表的Cronbach′sα系数为0.89,评估者间信度分析显示量表总分的组内相关系数(ICC)为0.85,量表包含的20个条目的ICC在0.78~0.94(P<0.01);评估者内信度分析显示量表的总分ICC为0.95,除b230听力外,量表包含的其它条目ICC在0.72~0.97(P<0.01)。结论基于ICF的失能评定工具与数字评定量表联合在临床失能评估应用中具有良好的内在一致性及评估者间信度和评估者内信度。

The reliability of a functioning assessment tool based on the International Classification of Functioning,Disability and Health

Objective To investigate the reliability of a tool based on the International Classification of Functioning,Disability and Health(ICF)in the assessment of functioning despite disability.Methods A total of 371 patients were assessed using a tool based on the ICF rehabilitation set combined with a numerical rating scale ranging from 0 to 10.The internal consistency,inter-rater reliability and intra-rater reliability were analyzed.Results The scale′s Cronbach′s alpha coefficient was 0.89.The inter-rater correlation coefficient was 0.85,and the correlations among the items ranged from 0.78 to 0.94.The intra-rater correlation coefficient with the scale was 0.95,with the item correlations ranging from 0.72 to 0.97.Only item b230 Hearing function did not correlate well.Conclusions The functioning assessment tool based on the ICF rehabilitation set when combined with a numerical rating scale has internal consistency,inter-rater reliability and intra-rater reliability sufficient for use in clinical practice.
