Transitions in Co-occurring Problematic Internet Use and Depressive Symptoms Among Adolescents: A Dual-Systems...

Area of Science:

• Psychology
• Adolescent Mental Health
• Behavioral Science

Background:

• Problematic internet use (PIU) and depressive symptoms frequently co-occur in adolescents.
• Dual-systems theory highlights the roles of motivational and control systems in PIU and depression.
• Limited understanding exists regarding how these systems influence the co-occurrence and transitions of PIU and depressive symptoms.

Purpose of the Study:

• To investigate profile transitions in co-occurring PIU and depressive symptoms among adolescents.
• To examine the predictive roles of dual-system factors (behavioral inhibition system and behavioral activation system) in these transitions.
• To identify distinct adolescent profiles based on PIU and depressive symptoms.

Main Methods:

• Longitudinal study with 4,181 Chinese adolescents at baseline and 2,705 at one-year follow-up.
• Utilized multiple imputation for missing data and conducted sensitivity analyses.
• Identified four distinct risk profiles: low-risk, depressive-dominant, PIU-dominant, and high-risk co-occurring.

Main Results:

• The low-risk profile was most stable; the depressive-dominant profile showed the highest improvement rate.
• Higher behavioral inhibition system predicted the emergence of symptomatic profiles.
• Higher behavioral activation system, lower emotion regulation difficulties, and higher self-control predicted symptom improvement, particularly in PIU.

Conclusions:

• Dual-system factors play significant roles across different co-occurring PIU and depressive symptom profiles in adolescents.
• Findings support the early identification of at-risk adolescents.
• Profile-specific interventions are recommended for adolescents exhibiting different risk patterns.
