The relationship of childhood bullying and paranoid thinking in a clinical population: the role of mediators

Abstract

A wealth of research evidence has been accumulating over the last two decades, highlighting the association of childhood trauma and psychosis. However, research has focused more on investigating the prevalence of childhood trauma in individuals with psychosis and not much consideration has been given to the role of underlying processes which may mediate this association.

Following a comprehensive literature review search, 32 studies were identified which fulfilled the search criteria and investigated the association between childhood trauma and psychosis in adulthood. This narrative literature review evaluates empirical evidence generated over the last two decades and builds upon the previous literature reviews in this area. In addition to the discussion of the prevalence of childhood trauma in psychosis, theoretical bases, causality, mediation, consideration has been given to the controversial and debatable issue of asking about childhood trauma from clients with psychosis.

The methodological limitations of the literature reviewed, as well as directions for future research have been offered. As the association of childhood trauma and psychosis can have far reaching implications, both in terms of assessment and intervention, these have been discussed in the final part of this review.
