The relationships among family income, parental depression, and adolescent aggression in South Korea: A latent growth mediation model

Although the Family Stress Model is well-established with many examples, there is relatively little information about South Korean families, which are known for greater bonding between parents and adolescents. The current study examined whether changes in parents' depression would mediate the relationship between income dynamics and youth development changes in South Korea. The participants were 561 families who had completed the Korean Welfare Panel Study at three time points that covered the full span from elementary to high school. A latent growth mediation model was used, and the results indicated that 1) family income was associated with parental depression and youth aggression over time and 2) early parental depression fully mediated the relationship between early family income and subsequent youth aggression rates over time. These findings have major implications for policies and interventions with regard to low-income South Korean families.
