This systematic review and meta-analysis examined the longitudinal relationship between co-rumination and depressive symptoms in adolescents, analyzing 46 datasets with 18,222 participants. The study found that T1 co-rumination predicted T2 depressive symptoms (β = 0.036, p = .020), while T1 depressive symptoms had a smaller association with T2 co-rumination (β = 0.031, p = .0495).
Key findings
- T1 co-rumination predicted T2 depressive symptoms with a β of 0.036.
- T1 depressive symptoms had a small association with T2 co-rumination (β = 0.031).
- Co-brooding showed the most robust forward association in sensitivity analyses.
- Measurement instruments significantly moderated the cross-lagged paths.
Why it matters
Understanding the relationship between co-rumination and depressive symptoms can inform prevention strategies in adolescents. Identifying maladaptive co-rumination patterns may help mitigate the risk of developing depressive symptoms.
