ABSTRACT
Objective: Many studies have demonstrated that childhood trauma is associated with later psychosis. However, the mechanisms underlying the pathway from childhood trauma to the emergence of psychotic symptoms remain unclear and continue to be an important research topic. This study aimed to explain how childhood trauma is related to psychotic symptoms, as well as the role that dissociation might play in mediating that relationship.
Methods: Childhood Trauma Questionnaire, Dissociative Experiences Scale, Psychoticism and Paranoid Ideation Subscales of Symptom Checklist-90-Revised were administered to 694 participants from the general population. To test mediating effects, partial least squares structural equation modeling (PLS-SEM) method was used.
Results: Childhood trauma had a statistically significant positive effect on the dissociative experiences, paranoid ideation, and psychoticism (p<.001). Dissociative experiences had a statistically significant positive effect on paranoid ideation and psychoticism (p<.001). The indirect effect of childhood trauma on both paranoid ideation and psychoticism through dissociative experiences was statistically significant (p<.001). Dissociative experiences played a mediating role in the effect of childhood trauma on both paranoid ideation and psychoticism score.
Conclusions: The current study demonstrates that in the general population, psychotic symptoms are correlated with childhood trauma and dissociation may be the main phenomenon underlying the pathway from childhood trauma to psychotic symptoms, in other words, childhood trauma may have an indirect effect on psychotic symptoms through dissociative experiences.
Keywords: Childhood trauma, dissociative experiences, psychotic symptoms, psychoticism, paranoid ideation.
