Problematic Internet Use and Loneliness: How Complex Is the Relationship? A Short Literature Review

PurposeThe Internet has become embedded into the life of billions of people worldwide. In some individuals, excessive Internet use impacts negatively on psychological and social functioning. Several studies over the last decades have focused on the relationship between Problematic Internet Use (PIU) and loneliness. The present review aims to provide an overview of the recent literature in this field and to suggest some critical questions.Recent FindingsA small-medium positive association between loneliness and PIU has been reported in several cross-sectional studies. However, the association becomes weaker when other variables are controlled for. Longitudinal studies suggest a dynamic relationship between PIU and loneliness.SummaryThere is ample evidence that PIU and loneliness are positively associated, but care should be taken to control for other related variables (e.g., depression). Over time, PIU and loneliness seem to be linked in a vicious cycle, with PIU as a possible starting point.
