Associations Between Depression and Problematic Social Media Use: A Longitudinal Study and Daily Diary Study

Area of Science:

• Psychology
• Public Health
• Digital Media Studies

Background:

• Problematic social media use (PSMU) is increasingly linked to depression.
• Limited research exists on the day-to-day and long-term temporal relationships between depression and PSMU.

Purpose of the Study:

• To investigate the bidirectional associations between daily depressive symptoms and PSMU.
• To examine the longitudinal relationship between depression and PSMU over a 9-month period.

Main Methods:

• Study 1: A 2-week daily diary study with 169 college students assessing depression and PSMU.
• Study 2: A 9-month longitudinal study with 473 adolescents assessing depression and PSMU at multiple time points.
• Analyses included dynamic structural equation modeling and longitudinal analyses.

Main Results:

• Daily depression predicted next-day PSMU, and daily PSMU predicted next-day depression, indicating a reciprocal daily relationship.
• Over 9 months, depression at an initial time point predicted later PSMU, but PSMU did not predict later depression.
• Depression appears to be a more consistent antecedent of PSMU in the long term.

Conclusions:

• Depression and PSMU exhibit a reciprocal relationship on a daily basis.
• Long-term, depression is a more significant predictor of problematic social media engagement.
• Findings support interventions targeting both depressive symptoms and maladaptive social media use.
