ABSTRACT

The purpose of this study was to investigate the effects of complex traumatic experiences during childhood on depression and hostility as adults and to verify the partial mediating effect of locus of internal-external control, which is considered a characteristic aspect of personality. For this purpose, 430 men and women in their 20s and 30s were sampled from Daegu and Gyeongbuk provinces, and the data from 407 participants were used in the final analysis. A trauma experience scale, locus of internal-external control scale, hostility scale, and depression scale were used as measurement tools. The mediating effect was analyzed using the structural equation model(SEM). The main results of this study were as follow. First, childhood complex trauma experience was positively related to external locus of control, depression, and hostility in adults and negatively related to internal locus of control. Second, both external and internal control partially mediated the effect of trauma on depression and hostility in adults. This suggests that the experience of complex trauma in childhood positively affects depression and hostility in adults through external control. In addition, even with complex traumatic experiences in childhood, depression and hostility in adults can be reduced if they have an internal locus of control. Based on these results, the implications, study limitations, and suggestions for future research were discussed.
