Abstract
Objective: Traumatic events in childhood have been implicated in the development of psychosis but, given that trauma is not in itself sufficient to cause psychosis, researchers have started to investigate other psychological constructs potentially involved in explaining this relationship. Given that self-disgust as a transdiagnostic construct plays a role in the development/maintenance of a range of mental health difficulties, the objective of this study was to investigate if self-disgust mediates the relationship between childhood trauma and psychosis. Method: A cross-sectional quantitative study design was used. Seventy-eight participants (Mage = 37.64 years, SDage = 11.57 years; 77% women; 88% White Caucasian) who reported experiencing clinical levels of psychosis were recruited using social media. The participants completed online survey measures of childhood trauma, self-disgust, experiences of psychosis, self-esteem, and external shame. The data were analysed using correlation and mediation analyses. Results: Significant indirect effects of childhood trauma on both positive (β = .17, BC 95% CI [.06, .30]) and negative symptoms (β = .26, BC 95% CI [.14, .40]) of psychosis via selfdisgust were observed. These effects remained despite the inclusion of self-esteem and external shame as control variables in the mediation models. Conclusion: This study is the first to show a mediating role for self-disgust in the relationship between childhood trauma and later psychosis. Although the findings should be considered preliminary until strengthened by further research, they nevertheless provide corroboration of the potential utility of self-disgust as a transdiagnostic construct from a theoretical perspective, but also from its potential to inform formulation and interventions.
