Objective: To test the reliability and validity of SNS Older Adults Measure(SNS-OA) among Chinese middle-aged and elderly groups. Methods: SNS Older Adults Measure, Internet Usage Questionnaire, Short Form of the Center for Epidemiologic Studies Depression Scale, UCLA Loneliness Scale, The Scale of Positive and Negative Experience, Satisfaction with Life Scale, Meaning in Life Scale, Perceived Social Support Scale and Lubben Social Network Scale were applied to 816 middle- aged and elderly people. Results: Exploratory factor analysis found that the revised scale with 17 items conformed to the five- factor model, which explained 75.35％ of the total variation; confirmatory factor analysis showed that it had a well goodness of fit (χ2 =301.63, df=108, χ2 /df =2.79, CFI=0.95, TLI=0.94, SRMR=0.05, RMSEA=0.07). The revised scale had the good reliability: Cronbach’s á coefficient was 0.91, and the test-retest reliability was 0.88. It was identified that the revised scale had good differentiation, criterion validity and measurement invariance across gender. SNSOA was significantly correlated with mental health indicators, social support and social network; SNS usage showed gender difference. Conclusion: The revised scale has good reliability and validity and it is suitable for Chinese middle-aged and elderly groups.

目的：检验老年人社交网络量表(SNS Older Adults Measure, SNS-OA)在中国中老年人中的信效度。方法：采用老年人社交网络量表、互联网应用问卷、抑郁量表、孤独感量表、正负向情绪量表、生活满意度量表、生命意义感量表、社会支持及社会网络量表对816名中老年人进行施测。结果：探索性因子分析发现，含17个条目的修订后量表符合五因素模型，解释总变异的75.35%；验证性因子分析显示其具有良好拟合度(χ~2/df=2.79, CFI=0.95, TLI=0.94,SRMR=0.05, RMSEA=0.07)。修订后量表信度较好，Cronbach’s α系数为0.91，四周后重测信度为0.88。量表还被证实具有良好区分度、效标关联效度及跨性别的等值性。该量表得分与心理健康各指标、社会支持和社会网络显著相关；量表使用具有性别差异。结论：修订后的量表具有良好的信效度，适用于中国中老年群体。
