Adverse Childhood Experiences and Suicidal Ideation in Early Adulthood: Focusing on the Mediation Effect of Depression and the Moderated Mediation Effect of Social Ecological Resilience

The purpose of this research was to determine whether depression plays a mediating role between adverse childhood experiences(ACEs) and suicidal ideation and to examine whether social ecological resilience had moderated mediating effects. The study model was designed based on PROCESS v.3.5 for SPSS by Hayes. A total of 309 samples was selected for the study, which consisted of adults aged 18 to 28 years old, and data was collected through a survey for the analysis. The main findings of this study are as follows : First, depression had a partial mediating effect in the relationship between ACEs Score and suicidal ideation. Second, social ecological resilience moderated the mediation effect of depression between ACEs and suicidal ideation. The results indicate that suicidal ideation in early adulthood was reduced by strengthening social ecological resilience. Thus, it would be useful to apply the social ecological resilience model to intervene the influence of ACEs on suicidal ideation in early adulthood.
