We investigated the effects of trauma and victimhood on pathological dissociation (measured by the Dissociative Experiences Scale Taxon (below, DES-T)) and healthy dissociation (measured by the Normal Dissociation Index (below, NDI)). A sample of 207 undergraduate students (164 female, and 43 male) was classified into the traumatic group (n = 42) and the non-traumatic stress group (n = 165). Multiple regression analysis indicated that trauma and the frequency of victimhood mildly and significantly affect DES-T (each β = .44, p = .005, 95% C.I. [.14, .75]; β = .42, p < .001, 95% C.I. [.25, .59]) and NDI (each β = .50, p = .002, 95% C.I. [.20, .81]; β = .41, p < .001, 95% C.I. [.25, .58]). However, the interactions were not significant. These results suggest that trauma and the frequency of victimhood affect pathological dissociation and healthy dissociation independently.
