Figure 2,which is an illustration of the analyses in Table 2, demonstrates that across all outcomes and all social network predictors, the effect sizes of Facebook use variables arecomparable to or greater than the effect sizes of real-world social network variables and also much more likely to be significant across all outcomes. These effect sizes are small, but that is to be expected; they are similar in magnitude to those found in other studies (12, 31) and reveal an important pattern regarding the nature of real-world social interaction compared with online interaction. Liking others’ content and clicking links posted by friends were consistently related to compromised well-being, whereas the number of status updates was related to reports of diminished mental health. Although having a greater number of Facebook friends showed a positive correlation with well-being in the cross-sectional models, it did not retain significance in the longitudinal models, which suggests that prior work (33) might have been confounded by other factors.
