脑卒中病人健康素养量表的编制及信效度检验

Development and reliability and validity test of the health literacy scale for stroke patients

[目的]编制脑卒中病人健康素养量表,并进行信度及效度检验。[方法]根据文献回顾及对15例脑卒中病人访谈的结果构建脑卒中健康素养的条目池,经研究小组讨论及专家评定后形成量表初稿。采用量表初稿对144例脑卒中病人进行测评,通过测评结果检测量表的信效度,修改后形成量表终稿。[结果]最终形成包括3个维度、20个条目的脑卒中病人健康素养量表。量表水平的内容效度指数为0.96,探索性因子分析后,取样适切量数值为0.915,因子分析提取的3个公因子累计方差贡献率为73.899%,量表总的Cronbach'sα系数为0.929,各维度的Cronbach'sα为0.926~0.942,其折半信度为0.819,2周后测得重测信度为0.932。[结论]编制的脑卒中健康素养量表,具有较高的信度和效度,可用于脑卒中病人的健康素养水平的测评。

Objective:To develop a health literacy scale for stroke patients,and to test its reliability and validity.Methods:According to the literature review and the results of interviews with 15 stroke patients,the item pool of stroke health literacy was constructed.Then the first draft of the scale was formed after research team discussion and experts evaluatin.The first draft of the scale was used to evaluate 144 stroke patients in order to test the reliability and validity of the scale.The final draft of scale was formed after revision.Results:The formed health literacy scale for stroke patients contained 3 dimensions,involving 20 items.The content validity index of scale⁃level was 0.96.After exploratory factor analysis,kaiser meyer olkin was 0.915.Cumulative variance contribution rate of three common factors extracted by factor analysis was 73.899%.The total Cronbach'sαcoefficient of the scale was 0.929.The Cronbach'sαcoefficient of each dimension was from 0.926 to 0.942.And its half-reliability was 0.819.The test⁃retest reliability was 0.932 after 2 weeks.Conclusions:The constructed health literacy scale for stroke patients had high reliability and validity,which could be used to evaluate the health literacy level of stroke patients.
