'Looking Up and Feeling Down'. The influence of mobile social networking site use on upward social comparison, self-esteem, and well-being of adult smartphone users

摘要

Exposure to carefully selected information on social networking sites (SNSs) showing a flawless self and an ideal life has been found to harm young individuals' self-esteem and well-being. However, SNS use is no longer limited to young people. Fueled by the sharp increase of smartphone ownerships, which allow users to access information about others anytime and anywhere, nowadays, a wide range of age groups uses SNSs. Accordingly, this study investigated the relationships between mobile SNS use, upward social comparison, self-esteem, and well-being for the first time. We employed a two-wave panel survey (N-T2 = 461) using a quota sample of adults. Results revealed that Facebook use predicted upward social comparison, which harmed individuals' self-esteem and well-being over time, while Instagram use directly influenced wellbeing negatively over time. Additionally, we found support for reciprocal relationships between upward social comparison on SNSs and self-esteem as well as well-being in a longitudinal context. The potential negative implications of SNS use on well-being are discussed.
