The purpose of this study was to examined stress response of people who have experienced a disaster, and to find out stress coping method for victims to minimize suffering from stress against the Hebei Spirit oil spill accident in Taean coastal area on December 7th, 2007. 186 residents in Taean who are older than 20s were chosen for this study. And interviewed by telephone for three times; 1st in Feb, 2008, 2nd in Sep, 2008, and 3rd in Sep 2009.
First, the path model was analyzed by the time order, and the tested path model fitted the data well. The results were: 1) the worse Taean residents got damaged, the more depression, anxiety, and hostility for the 1st time of test were, and 2) the worse they got damaged, the higher score of suicide ideation for the 2nd time of test was. And the first time-point depression score and the 2nd suicide ideation decreased the 3rd subjective well-being. Likewise, suicide ideation at 2nd test decreased the 3rd subject well-being. Besides mediating effect of 1st depression in the relationship between level of damage and 2nd suicide ideation was significant and also mediating effect of 1st depression and 2nd suicide ideation in the relationship between level of damage and 3rd subjective well-being was significant.
Second, the hierarchical regression was used to examine effects of self-disclosure between the suicide ideation after traumatic events and subjective well-being. Three factors interaction effect of level of damage, suicide ideation, and self-disclosure were statistically significant. In case that the suicide ideation scores are high in highly damaged group, self-disclosure showed an impact significantly on subject well-being. Similarly, when the suicide ideation were low in the group which has relatively less damage, self-disclosure was also significantly associated with subjective well-being.
Lastly, this study can be applied to common people. And the self-disclosure could be widely used as a way of stress coping for anyone who experienced traumatic events in life. Moreover, this study investigated how the effect of traumatic events proceeded using the causality processing by reviewing longitudinal data. A limitation of this study is that this research could not take the physical reaction into account even if the oil spill might seem to be highly related to health problem. In the discussion, other limitation and suggestion for future study were presented.
