Association between family conflict resolution methods and depressive symptoms in South Korea: a longitudinal study

We investigated the relationship between family conflict resolution and depression, focusing on each component of family conflict resolution to determine which factors have stronger associations with depression. We used data from 2008 to 2015 of the Korea Welfare Panel Study. Our final sample included 3565 participants. For each participant, we included at least 2–8 years of follow-up data with a mean follow-up time of 4.05 ± 2.52 years. To identify the relationship between new-onset depressive symptoms and participants’ family conflict resolution styles, we performed generalized estimating equation analysis with autoregressive working correlations to estimate adjusted odds ratios for new-onset depressive symptoms adjusted for covariates. Compared with positive family conflict resolution, negative family conflict resolution had a higher odds ratio for depressive symptoms (aOR 1.80, 95% CI 1.42–2.29). This relationship was strongly founded on participants who were women (aOR 2.35, 95% CI 1.55–3.94) with experience of verbal aggression (aOR 1.84, 95% CI 1.42–2.37) and threatening behaviors (aOR 1.89, 95% CI 1.25–2.85). Negative family conflict resolution has long-term associations with an elevated risk of depressive symptoms. In particular, we observed higher risks of depression with verbal and psychological conflict than with physical conflict. Health care providers and health policymakers should support the management and development of methods for dealing with family conflict to improve mental health at a family level, as well as an individual level.
