颅脑损伤ICF评定量表信效度的初步研究

Reliability and validity study of ICF assessment of traumatic brain injury

目的:研究颅脑损伤(TBI)国际功能、残疾和健康分类(ICF)评定量表的信度与效度。方法:TBI患者100例,均采用TBI的ICF评定量表、Fugl-Meyer肢体运动功能评定表和改良Barthel指数(MBI)进行评定。效度研究采用结构效度和效标效度的方法,信度研究采用评定员间信度和内部一致性的分析方法。评定员间的信度检验用Kendall's W值相关;内容一致性检验用Cronbach's Alpha值分析;效标效度用Pearson相关,判断3个量表间的相关性。结果:ICF评定量表4个维度中,活动与参与方面Cronbach's Alpha系数为0.927,身体功能方面Cronbach'sAlpha系数为0.739,Kendall's W值为0.700(均P<0.05)。ICF评定量表身体功能方面与Fugl-Meyer肢体运动功能评定表间的Pearson系数为0.754,呈现负相关性(P<0.05);ICF评定量表活动与参与方面与MBI评定表间Pearson系数为0.785,呈现负相关性(P<0.05)。结论:TBI的ICF评定量表具有一定的可靠性和有效性,能更好地反映肢体运动功能和日常生活活动能力。

Objective：To study the reliability and validity of the ICF assessment of traumatic brain injury. Meth- ods：All 100 patients, diagnosed as having traumatic brain injury, were evaluated by ICF, Fugl-Meyer upper extremity motor function assessment and modified Barthel Index （MBI）. The methods of construct validity and criterion validi- ty were used to study validity,while the methods of assessor reliability and internal consistency were used to study reliability. Kendall＇s W was used to test the reliability of assessors,and Cronbach＇s Alpha value was used to analyze content consistency. Pearson correlation was used to test the criterion validity in order to determine the correlation a- mong the three scales. Results：Among the four dimensions of the ICF,Cronbach＇s Alpha coefficient of activities and participation was 0. 927,Cronbach＇s Alpha coefficient of body function was 0. 739,and Kendall＇s W value was 0. 700 （all P〈0.05）. The Pearson coefficient between physical functioning of the ICF and Fugl-Meyer motor function as- sessment was 0. 754 （P〈0.05） ,showing a negative correlation;while the Pearson coefficient between activities and participation of the ICF and MBI was 0. 785 （P〈0.05） ,showing a negative correlation. Conclusion：The ICF of trau- matic brain injury has good reliability and validity,which can better reflect the limb motor function and daily life ac- tivities.
