A growing number of studies have examined the psychological corollaries of using social networking sites (SNSs) such as Facebook, Instagram, or Twitter (often called social media). The interdisciplinary research area and conflicting evidence from primary studies complicate the assessment of current scholarly knowledge in this field of high public attention. We review meta-analytic evidence on three hotly debated topics regarding the effects of SNSs: well-being, academic achievement, and narcissism. Meta-analyses from different laboratories draw a rather equivocal picture. They show small associations in the r = .10 range between the intensity of SNS use and loneliness, self-esteem, life satisfaction, or self-reported depression, and somewhat stronger links to a thin body ideal and higher social capital. There is no indication for potential devastating effects of social media on school achievement; social media use and school grades are unrelated for adolescents. The meta-analyses revealed small to moderate associations between narcissism and SNS use. In sum, meta-analytic evidence is not in support of dramatic claims relating social media use to mischief.

社交媒体在破坏我们的生活吗？荟萃分析证据综述

越来越多的研究检查了使用社交网站（SNS）（例如Facebook，Instagram或Twitter（通常称为社交媒体））的心理推论。跨学科研究领域和来自基础研究的相互矛盾的证据使这一在公众高度关注的领域中当前学术知识的评估变得复杂。我们回顾了有关SNS影响的三个热门话题的荟萃分析证据：幸福感，学术成就和自恋。来自不同实验室的荟萃分析得出了一个相当模棱两可的图景。他们显示，在SNS使用强度与孤独，自尊，生活满意度或自我报告的抑郁之间，r = .10的范围内存在较小的关联，并且与瘦弱的理想和更高的社会资本之间的联系更为紧密。没有迹象表明社交媒体可能对学校成绩造成破坏性影响；社交媒体的使用和学校成绩与青少年无关。荟萃分析显示，自恋和SNS使用之间存在小到中等的关联。总而言之，荟萃分析证据不支持有关社交媒体使用与恶作剧有关的戏剧性主张。
