Abstract：
The present study aimed to explore whether the tendency to compare one\'s abilities and opinions to those of others (social comparison orientation) could longitudinally mediate the association between narcissism and problematic SNS use. A total of 1,196 college students were assessed at three time points over 22 months. The results showed that narcissism at time 1 was positively related to problematic SNS use at time 3 and that ability comparison at time 2 longitudinally mediated the association between narcissism at time 1 and problematic SNS use at time 3, whereas the longitudinal mediating effect of opinion comparison at time 2 was not significant. These findings suggest that narcissism more distally and ability comparison more proximally may be risk factors for engaging in problematic SNS use, and it is important to distinguish between types of social comparisons in problematic SNS use behaviors.
摘要：
本研究旨在探讨将自己的能力和观点与他人的能力和观点进行比较的倾向（社会比较取向）是否可以纵向介导自恋与有问题的SNS使用之间的关联。在22个月的三个时间点，总共对1,196名大学生进行了评估。结果表明，时间1的自恋与时间3的问题SNS使用呈正相关，时间2的能力比较纵向介导了时间1的自恋与时间3的问题SNS使用之间的关联，而在时间2的意见比较的纵向中介作用不显著。这些发现表明，更远端的自恋和更近端的能力比较可能是参与有问题的SNS使用的风险因素，在有问题的SNS使用行为中，区分社会比较的类型是很重要的。
