Kate et al. (2020) conducted a meta-analysis to determine the prevalence of dissociative disorders and episodes among university students. The study aimed to determine whether the trauma model, or the fantasy models of dissociation better explained dissociative disorder diagnoses. The trauma model attributes dissociation to the biopsychosocial consequences of trauma, while the fantasy model explains that dissociation occurs in individuals who are prone to fantasizing in times of extreme stress.
From the included studies examining clinically diagnosed dissociative disorders, the prevalence rate of any dissociative disorder diagnoses on a college campus was 11.4%, with rates being comparable across studies. The prevalence of self-reported dissociative experiences was significantly varied across included studies; therefore, no percent prevalence was determined from the meta-analysis. Overall, it was determined that trauma model was more accurate in explaining college students’ dissociative disorder diagnoses. Kate et al. (2020) hope to use these findings to improve treatment accessibility and efficacy to decrease frequency of dissociative episodes.
