online self-disclosure was a significant predictor of users’ friendship quality. However, there
was an inverse relationship between ‘‘social’’ SNS use and online self-disclosure, and no relationship
between friendship quality based on SNS use and well-being. It should be noted that generalizations
of our findings should be made cautiously. The cross-section design and self-reported usage of SNS would
also be limitations. Experimental and longitudinal studies should be conducted to provide stronger evidence
of causal relations among variables examined in this study.
