老年人健康增强生活方式量表(筛选版)的汉化及信效度检验

Development of the Chinese version of health enhancement lifestyle profile-screener and its reliability and validity in the elderly

目的基于Rasch模型和经典测量理论(classical test theory,CTT)对健康增强生活方式量表(筛选版)(health enhancement lifestyle profile-screener,HELP-screener)进行中文修订并探讨该量表在老年人群中的信效度。方法2020年12月至2021年3月采用方便抽样的方式在四川省城市和农村地区选取了447位老年人作为研究对象,采用经翻译、修订形成的中文版健康增强生活方式量表(筛选版)(HELP-CS)进行问卷调查。结合Rasch模型和CTT两种测量方法对问卷进行单维性、拟合度检验、难度分析以及内部一致性、重测信度、效标关联效度、区分效度评价。结果根据初测问卷结果删除第9题,保留14个题目形成正式问卷。Rasch模型分析结果显示,HELP-CS满足单维标准,第2题和第14题残差均方为1.49、1.41,在可接受范围以内;第10题和第12题难度阈值最高,分别为1.87和1.91;部分题目存在性别差异。量表的Cronbach′sα系数为0.719,两个月后的重测信度为0.704。使用适合老年人群的健康促进生活方式量表(health promoting lifestyle profile-CE,HPLP-CE)为效标,相关系数为0.581。结论HELP-CS量表在老年人群体中具有良好的适应性和信效度,可以作为一种快速有效的筛查工具在老年人生活方式的研究中使用。

Objective To translate the English version of the health enhancement lifestyle profile-screener into Chinese and assess its reliability and validity based on classical test theory(CTT)and Rasch model among the elderly.Methods A total of 447 older adults from rural and urban areas in Sichuan Province from December 2020 to March 2021 were selected by convenience sampling,and were surveyed with the revised Chinese version of health enhancement lifestyle profile-screener(HELP-CS).Rasch and CTT-based approaches were used to evaluate the unidimensionality data-model fit,internal consistency,test-retest reliability,criterion validity and discriminant validity of the questionnaire.Results According to the results of the initial test questionnaire,the ninth question was deleted,and 14 items were retained to form a formal questionnaire.The formal test results showed that HELP-CS met the unidimensionality,and the residual mean square error for item 2 and 14 were within the acceptable range,which were 1.49 and 1.41.Item 10 and 12 had the highest logits,which were 1.87 and 1.91 respectively.There were gender differences in some topics.The Cronbach′sαof the scale was 0.719,and the test-retest reliability was 0.704 after two months.The criterion correlations with HPLP-CE were 0.581.Conclusion HELP-CS has good adaptability,reliability and validity in the elderly,and can be used as a quick and effective screening tool in the study of the lifestyle of the elderly.
