The Effect of Social Network Site Use Based on WeChat on Life Satisfaction for the Elderly: The Mediating Roles of Online Self-Disclosure

摘要: 目的：探讨老年人社交网站使用、网络自我表露及生活满意度之间的关系，为提高老年群体的生活满意度水平提供新依据。方法：采用社交网站使用强度问卷、网络自我表露量表和生活满意度量表对598名老年人进行调查。结果：① 老年人的社交网站使用、网络自我表露和生活满意度问卷得分存在显著的年龄、月收入和教育程度等人口学变量差异，其中55~59岁、60~69岁老年人社交网站使用均显著高于70岁以上老年人。在月收入上，4000以上及2000~4000的老年人的社交网站使用及生活满意度显著高于2000以下，月收入4000以上的老年人网络自我表露得分显著高于2000~4000及2000以下。高中、大专及本科以上学历的老年人的社交网站使用、网络自我表露和生活满意度显著高于初中以下老年群体。②老年人的社交网站使用与生活满意度呈显著正相关(r = 0.219, P < 0.01)，与网络自我表露呈显著正相关(r = 0.777, P < 0.01)。老年人的网络自我表露与生活满意度呈显著正相关(r = 0.282, P < 0.01)。③ 网络自我表露在老年人社交网站使用与生活满意度关系中起完全中介作用(β = 0.317, P < 0.001)。结论：老年人的社交网站使用对其生活满意度具有正向预测作用，且全部影响可能是通过网络自我表露行为来实现。

Abstract: Objective: To explore the relationship among social network site use, online self-disclosure, and life satisfaction among the elderly people, in order to provide new evidence for improving the level of life satisfaction among the elderly population. Method: A survey was conducted on 598 elderly peo-ple using the Social Network Site Use Questionnaire, online Self-Disclosure Scale, and Life Satisfac-tion Scale. Results: ① There are significant differences in demography variables such as age, monthly income and education level in the elderly’s social network site use, network self-disclosure and life satisfaction questionnaire scores, among which the social network site use, of 55~59 years old and 60~69 years old is significantly higher than that of the elderly over 70 years old. In terms of monthly income, the intensity of social network site use, and life satisfaction of elderly people with a monthly income of over 4000 and 2000~4000 are significantly higher than those with a monthly income of below 2000, and the score of online self-disclosure of elderly people with a monthly in-come of over 4000 is significantly higher than that of those with a monthly income of 2000~4000 and below 2000. The intensity of social network site use, online self-disclosure, and life satisfaction of elderly people with high school, college, and bachelor’s degree or above are significantly higher than those of the elderly group below junior high school. ② The use of social networks by the el-derly is significantly positively correlated with life satisfaction (r = 0.219, P < 0.01), and is signifi-cantly positively correlated with online self-disclosure (r = 0.777, P < 0.01). The online self-disclosure of elderly people is significantly positively correlated with life satisfaction (r = 0.282, P < 0.01). ③ Online self-disclosure plays a complete mediating role in the relationship between So-cial Network Site Use and life satisfaction in elderly people (β = 0.317, P < 0.001). Conclusion: The use of social networks by the elderly has a positive predictive effect on their life satisfaction, and the entire impact may be achieved through online self-disclosure behavior.
