Correlations of online social network size with well-being and distress: A meta-analysis

This meta-analysis examines the correlations of the number of social network site (SNS) friends with well-being and distress, based on 90 articles consisting of 98 independent samples on correlations of online social network size (OSNS) with happiness, life satisfaction, self-esteem, anxiety, depression, combined anxiety and depression, loneliness, social anxiety, social loneliness, well-being and distress. The correlations between OSNS and well-being indicators are positively weak (from .06 to .15), whereas those for distress indicators are inconclusive (from -.19 to .08). Studies recording the OSNS based on the participant profile have larger mean effect sizes for well-being (.21) and self-esteem (.31) than those based on self-reporting (.06 and .05, respectively). The correlation between OSNS and self-esteem is stronger in samples with a smaller mean network size.
