Factors affecting depression in adolescents with increased suicidal ideation during the COVID-19 pandemic.

Abstract

This study examines factors influencing depression in adolescents with increased suicidal ideation during the COVID-19 pandemic, based on an ecological model and using data from the Korean Children and Youth Panel Survey, 2018. We selected adolescents whose suicidal ideation increased between the third and fourth years of the pandemic and who identified their parents as their guardians. Factors related to depression in adolescents were analyzed using stepwise multiple regression, while considering personal and environmental characteristics in the family and school domains. All models were significant, and Model 3 explained 26.8% of the variance. In Model 3, personal characteristics-physical activity, sleep quality on school days, and smartphone dependence-affected adolescents' depression. Parents' life satisfaction and a rejective childrearing attitude were also found to be significant factors affecting adolescents' depression, along with school life satisfaction and school type. Our findings can inform evidence-based nursing interventions to reduce depression in adolescents with increased suicidal ideation. They can also contribute to building strategies to promote mental health in schools after the pandemic, forming healthy life habits, and laying the foundation for lifelong health.
