社会支持是影响中国老年人心理健康的关键性因素。从社会支持嵌入、接收的社会支持、社会支持的感知力这三个非正式社会支持的维度出发,从孤独感、沮丧感及对生活满意度这三个方面来衡量中国老年人的心理健康,可以发现,身体状况、家庭关系的满意度和对社会支持的感知力是有效预测老人心理健康的主要因素。 Social support is a key factor that affects the mental health of the elderly in China. Starting from three dimensions of informal social support such as social support embedding, receiving social support, and social support perceived power, we measure the mental health of Chinese seniors from three aspects: loneliness, frustration and life satisfaction, It can be found that the physical condition, the satisfaction of family relationships and the perception of social support are the main factors that can effectively predict the mental health of the elderly.
