Dissociation mediates the relationship between childhood maltreatment and subclinical psychosis

ABSTRACTMore than a third of the population report childhood adversity, and these experiences are associated with an increased risk of clinical and subclinical psychosis. The reason why some people go on to develop mental health problems and others do not is a key question for study. It has been hypothesized that dissociative processes mediate the relationship between early adversity and psychosis. The current study assessed whether dissociation, and specifically depersonalization (one component of dissociation), plays a mediating role in the relationship between childhood maltreatment and both hallucination proneness and delusional ideation. The study used a cross-sectional design and recruited a student sample to assess these relationships in a nonclinical group. Dissociation mediated the relationship between early maltreatment and both hallucination proneness and delusional ideation. In terms of specific dissociative processes, depersonalization did not mediate hallucination proneness or delusional ide...
