Abstract

Relationships have been well established between adverse childhood experiences (ACEs) and later psychosis (29 systematic reviews) or violence (4 systematic reviews). To date, just one review has explored childhood maltreatment, specifically, and violence risk with psychosis. We conducted a systematic review and meta-analyses of a wider range of ACEs and later psychosis with actual violence compared with psychosis alone, violence alone or neither, completing searches in January 2021. In all, 15 studies met inclusion criteria, but only six included all four groups of interest. Two substantial studies recorded ACEs from sources independent of those affected and probably before emergent psychosis or violence; others relied on retrospective recall. Meta-analyses were possible only for within-psychosis-group comparisons; histories of physical abuse, sexual abuse, and having a criminal/violent parent or living with family alcohol/drug use were each associated with around twice the odds of psychosis with violence as psychosis alone. Although ACE measures in the four-way comparisons were too divergent for firm conclusions, abuse histories, and parental criminality emerged as likely antecedents, one study evidencing psychosis as mediating between ACEs and violence. Without longitudinal prospective study, pathways between ACEs and later problems remain unclear. Our findings add weight to the case for exploring ACEs in addition to abuse as possible indicators of later violence among people with psychosis and for trauma-informed interventions, which is important because some people are reluctant to disclose abuse histories.
