Longitudinal relations among online social activities, peer relationship problems, and well-being in children: The moderating effect of extraversion.

Prior research has predominantly examined the relations between online social activities (OSA) and mental health among adolescents and adults, with comparatively less emphasis placed on children, particularly concerning positive indicators of subjective health, such as well-being. The relations between OSA and well-being are likely intricate and necessitate meticulously designed methodologies to investigate the associations and their underlying mechanisms. This longitudinal study employed the random intercept cross-lagged panel models to explore the dynamic relations between OSA and well-being, considering peer relationship problems as a potential mediator and extraversion as a moderator of the associations, while distinguishing between- and within-person effects.
