摘要： 背景　随着人口老龄化问题加剧，老年人心理健康问题受到越来越多的关注。了解社区老年人社会支持及心理健康状况，有助于为老年人心理健康问题提供新的解决思路。目的　调查社区老年人社会支持和心理健康状况，并分析两者之间的关系。方法　2015年10—11月选取南京市鼓楼区60岁及以上老年人，采用自编一般情况问卷、社会支持评定量表、老年心理健康量表（城市版）调查，使用SPSS 20.0软件进行数据处理与分析。结果　共发放问卷4 000份，全部收回，其中有效问卷3 535份，有效回收率为88.38%。社会支持评定量表总分、客观支持、主观支持、支持利用度维度得分与老年心理健康量表总分、认知效能、情绪体验、自我认识、人际交往、适应能力维度得分均呈正相关（P<0.05）。除主观支持对适应能力直接效应不显著外，客观支持、主观支持、支持利用度对老年心理健康量表的5个维度和老年心理健康量表总分均有直接效应（P<0.05），分别能解释认知效能的6.4%、情绪体验的17.9%、自我认识的18.2%、人际交往的19.4%、适应能力的12.9%、老年心理健康量表总分的20.5%。支持利用度对老年人心理健康影响最大（β=0.278）。结论　社区老年人社会支持与心理健康呈正相关，其中支持利用度对社区老年人心理健康的影响最大，社区服务中注重提高老年人社会支持对于维护社区老年人心理健康具有极为重要的积极影响。
