Abstract

Abstract: Objective　To evaluate the reliability and validity of the second Chinese version of Short-Form 12 Item Health Survey（SF-12v2） in elderly people with community home-based care. Methods　By use of two-stage sampling，a total of 451 older adults with community home-based care were recruited from Guangzhou from July to November 2017. They were surveyed with the Chinese version of SF-12v2. The criterion validity the Chinese version of SF-12v2 was determined by comparison with the ordinal response data of the Chinese version of the Euroqol Group's 5-Domain 5-Level Questionnaire（EQ-5D-5L）. Cronbach's α and Spearman-Brown prophecy formula were used to measure the reliability of the Chinese version of SF-12v2. The validity analysis of the Chinese version of SF-12v2 consisted of content validity（convergent validity and divergent validity），construct validity and criterion validity. Results　The Cronbach's α and split-half reliability with Spearman-Brown adjustment of the Chinese version of SF-12v2 were 0.876，0.873，respectively. The convergent validity and divergent validity for the 8 domains of the Chinese version of SF-12v2 were all 100.0%. Two factors were extracted，explaining 65.94% of the total variance. The scores of physical functioning domain of the Chinese version of SF-12v2 showed a medium correlation with the scores of 4 domains of the Chinese version of EQ-5D-5L，mobility，self-care，usual activities，and pain/discomfort（r=0.591，0.436，0.606，0.590； P<0.01） . The scores of mental health domain of the Chinese version of SF-12v2 had a medium correlation with the scores of the domain of anxiety/depression of the Chinese version of EQ-5D-5L（r=0.517，P<0.01） . Conclusion　The Chinese version of SF-12v2 has good reliability and validity in objectively assessing the health status of older adults with community home-based care.

摘要： 目的　探讨应用健康调查12条简表第2版（SF-12v2量表）评价社区居家养老模式下老年人健康状况的信度和效度。方法　2017年7—11月采用两阶段抽样法抽取广州市451名社区居家养老的老年人为研究对象，应用SF-12v2量表对其健康状况进行调查，同时采用欧洲五维健康量表5个维度（EQ-5D-5L）的定序数据作为效标。SF-12v2量表信度分析采用Cronbach's α系数和Spearman-Brown分半信度系数，效度分析采用内容效度（集合效度与区分效度）、结构效度和效标效度。结果　信度方面，SF-12v2量表总的Cronbach's α系数为0.876，两个分半量表的Spearman-Brown分半信度为0.873。效度方面，8个维度的集合效度和区分效度均为100.0%，因子分析提取公因子共2个，累计解释65.94%的总变异，SF-12v2生理健康子量表总分与EQ-5D-5L量表行动能力、自我照顾、日常活动、疼痛/不舒服维度中度相关（r值分别为0.591、0.436、0.606、0.590，P<0.01），SF-12v2心理健康子量表总分与EQ-5D-5L量表焦虑/沮丧维度中度相关（r=0.517，P<0.01）。结论　SF-12v2量表应用于社区居家养老模式下老年人健康状况评价时，具有较好的信度和效度，能够客观反映老年人的健康状况。
