Abstract

PURPOSE
The purpose of this study was to construct and test a hypothetical model about impact of parents' problem drinking on suicidal ideation of their children who are university students and the multiple mediating effects of childhood trauma, experiential avoidance, and depression based on stress-vulnerability model.
METHODS
A purposive sample of 400 university students was recruited from three universities in provincial areas and the data were collected between October and November 2016. The collected data were then analyzed using SPSS 20.0 and AMOS 20.0 programs. For data analysis, descriptive statistics, factor analysis, and structural equation modeling were performed. Multiple mediating effects analysis using phantom variable and bootstrapping were implemented to verify the mediating effect of the research model.
RESULTS
We found no significant direct effect on depression and suicidal ideation of parents' problem drinking, but multiple mediating effects of childhood trauma and experiential avoidance between parents' problem drinking and depression (B=.38, p=.001). The path from parents' problem drinking to suicidal ideation was significantly mediated by childhood trauma and depression (B=.02, p=.016) and by childhood trauma, experiential avoidance, and depression (B=.05, p=.011), but experiential avoidance did not have a significant direct effect on suicidal ideation (B=.02, p=.616).
CONCLUSION
Based on the results of this study, it can be suggested that in order to decrease depression and prevent suicide of university students, considering of parents' problem drinking and childhood trauma, intervention methods that decreased chronic use of experiential avoidance and strengthen acceptance should be developed and made available to them.
