Examining the interrelationships of school connectedness, social anxiety, and problematic social network use in adolescents.

Introduction: While social networks have become an integral part of people's lives, they also bring the potential for negative consequences, with problematic social network use emerging as a noteworthy concern, especially among adolescents. Guided by social control theory, this study examined bidirectional relationships between problematic social network use and its influencing factors: school connectedness and social anxiety.

Methods: Random intercept cross-lagged panel models were employed to examine the bidirectional relationships among school connectedness, social anxiety, and problematic social network use.
