Objectives: There were some studies that had explored connection among dissociation, coping strategies, and locus of control in non-clinical population. This study examined the relationship among dissociation, locus of control, and ways of coping style using general linear model(GLM) in college aged students. Methods: 286 Korean undergraduates had completed Dissociation Experience Scale-Korean version, Internal-External control Scale, and The Ways of Coping Checklist. We divided the students into two groups(DES≥20, N=81; DES<20, N=205) to evaluate differences in these variables. Pearson correlation test and regression analysis was performed to evaluate relationship among the variables. We used GLM to investigate the differences in dissociation, locus of control, and ways of coping style. We also divided the students into other two groups(DES-T≥20, N=28; DES-T=0, N=31) to evaluate the link to pathological dissociation and used the same methods as DES. Results: There were statistically significant correlations among dissociation, external locus of control, and passive coping strategies(emotional focused and wishful thinking). In regression analysis, passive coping strategies influence dissociation. In high DES group, scores of external locus of control and passive coping strategies was higher than low DES group. In addition we found the similar relationship in groups divided by DES-T. Conclusion: A significant relationship among dissociation, external locus of control, and passive coping strategies was found in college aged students. These results suggested high dissociators tended to use external locus of control and passive coping strategies in non-clinical population. Further studies with sufficient subjects are needed to clarify the link to DES-T.
