疾病获益感量表在缺血性脑卒中病人照顾者中的信效度检验

Reliability and validity test of the Benefit Finding Scale in caregivers of ischemic stroke patients

[目的]检验疾病获益感量表在缺血性脑卒中病人照顾者中的信效度。[方法]采用照顾者一般资料调查表、疾病获益感量表对湖州市某三级甲等医院就诊的缺血性脑卒中照顾者160例进行调查。[结果]疾病获益感量表的Cronbach′sα系数为0.939,各维度的Cronbach′sα系数为0.813~0.976。量表的折半信度为0.869,各维度的折半信度为0.754~0.884。量表各个条目与其对应维度总分的相关系数为0.526~0.982,5个维度之间的相关系数为0.335~0.774,各维度与总分的相关系数为0.673~0.890。探索性因子分析提取4个公因子,累积方差贡献率为69.72%。[结论]疾病获益感量表具有良好的信效度,适合用来评估缺血性脑卒中主要照顾者的疾病获益感情况。

Objective:To test the reliability and validity of Benefit Finding Scale in caregivers of ischemic stroke patients.Methods:A survey,involving 160 caregivers of ischemic stroke patients in a tertiary grade A hospital in Huzhou city,was conducted by using the general information questionnaire of caregivers and Benefit Finding Scale.Results:The Cronbach′sαcoefficient of Benefit Finding Scale was 0.939.And the Cronbach′sαcoefficient of each dimension ranged from 0.813 to 0.976.The split‑half reliability of scale was 0.869.And the split‑half reliability of each dimension ranged from 0.754 to 0.884.The correlation coefficients between score of every item and total score of its corresponding dimension ranged from 0.526 to 0.982.The correlation coefficients of 5 dimension ranged from 0.335 to 0.774.And the correlation coefficients between score of every dimension and total score of scale ranged from 0.673 to 0.890.Based on exploratory factor analysis,four common factors were extracted.The cumulative contribution rate was 69.72%.Conclusion:The Benefit Finding Scale has good reliability and validity,which is suitable for evaluating the disease benefit finding in main caregivers of ischemic stroke patients.
