Objectives：Dissociative experiences are conceptualized as existing on a continuum raging from relatively common everyday occurrences to more pathological forms of dissociation. Although dissociative experiences are often precipitated by stress or trauma, there may be an underlying vulnerability or diathesis for experiencing dissociation. Previous research investigating personality traits and dissociative experience in non-clinical samples reported significant relationships of dissociation with Neuroticism and Openness of NEOPI-R. The present investigation sought to explore the relationship between dissociation and personality dimensions.
Methods：The relationship between dissociative experiences and personality dimension was investigated in a sample of 214 undergraduate students. Personality characteristics was measured by the NEOPI-R, dissociative experiences by the DES-K(Dissociation Experience Scale-Korean version), and pathological dissociation by DES-T(Dissociation Experience Scale-Taxon). We divided the students into two groups according to DES-K (DES-K≥20, N=60；DES-K<20 N=154) and DES-T scores(DES-T≥20, N=21；DES-K<20 N=193) to evaluate differences in personality domains of NEOPI-R. Chi-square test and t-test was used for differences in personality domains of NEOPI-R and demographic variables according to variable. Pearson correlation test was used for relationship among the NEOPI-R, DES-K and DES-T. We also used stepwise and logistic regression analysis to evaluate accountability of personality domains for dissociative experiences.
Results：In high DES-K group, scores of Neuroticism(t=4.404, p=.000) and Openness(t=2.334, p=.021) domain was higher and score of Conscientiousness(t=-2.468, p=.014) was lower than low DES-K group. DES-T groups also had similar results in the t-test. In the total samples, score of DESK was correlated with scores of Neuroticism(r=.206, p<.01) and Openness(r=.237, p<.01). In high DES-K and DES-T samples, there was no correlation between DES and NEOPI-R. But in low DES-K and DES-T samples, there was a correlation between DES and Neuroticism. In the stepwise regression
analysis, scores of DES-K were explained partly by Neuroticism and Openness and DES-T by Openness and Neuroticism. In the logistic regression analysis, DES-K group was explained partly by Neuroticism and Openness and DES-T by Openness and Conscientiousness.
Conclusion：As hypothesized, The Neuroticism and Openness domain accounted for the great portion of variance in the dissociative experiences. Compared DES-K, there were some differences in case of DES-T. This result suggested that there were some differences between normative dissociation and pathological dissociation. Extensive study is needed in dissociative disorder patients for investigating the pathological dissociation.
