Abstract

There is now substantial evidence that childhood adverse events are a significant risk factor for symptoms of psychosis in both clinical and community samples. Both childhood trauma and positive symptoms of psychosis are associated with an increased risk of self-harming behaviours. Therefore the current study aimed to consider the relationship between retrospective reports of childhood adversity, sub-clinical positive symptoms of psychosis and self-harm in a non-clinical community sample. The study employed a cross-sectional survey design, distributed online. Participants were asked to complete psychometric assessments relating to: demographic characteristics including past-year substance misuse; childhood adversity; sub-clinical symptoms of psychosis (delusions and hallucinations) and self-harming behaviours. The results found that, after controlling for substance misuse, childhood adversity predicted significant variance in sub-clinical delusions and hallucinations in the general population. Both symptoms of psychosis and childhood adversity increased the risk of self-harming behaviours. Positive symptoms partially mediated the relationship between early adversity and self-harming behaviours. For some people, the sequelae of early adversity including sub-clinical delusions and hallucinations may increase the risk of self-harming behaviours. Future research would benefit from considering the role of dissociation in these relationships and the affective impact of pseudo-psychotic experiences. Practitioners should consider the impact of childhood adversity, unusual perceptual experiences and distorted beliefs when working with people who self-harm. The current research was limited by the cross-sectional survey design and non-random sampling methodology.
