Co-developmental trajectories of specific problematic usage of the internet: Associations with microsystem predictors and adolescents' mental health outcomes

Key Points

This research aims to explore the relationships between different forms of problematic internet usage and their predictors while examining their effects on adolescents' mental health.
Analyzed co-developmental trajectories of internet usage forms.
Investigated microsystem predictors related to internet usage.
Examined mental health outcomes in adolescents.
Identified distinct patterns of problematic internet usage.
Found significant associations between microsystem predictors and internet usage.
Demonstrated cumulative effects on adolescent mental health outcomes.

Abstract

These findings support the Spectrum Hypothesis from a developmental perspective, highlighting the importance of considering heterogeneity in understanding the co-developmental patterns of PUI forms, their microsystem predictors, and cumulative effects on adolescent mental health.
