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。

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.
