Traumatic life events, self-disturbances, cognitive biases and psychosis proneness were assessed with self-report questionnaires. The direct and an indirect model of the relationship between traumatic life events and psychosis proneness were compared using path analyses with structural equation modelling in a cross-sectional study.RESULTS: There was a significant direct effect of traumatic life events on psychosis proneness.

Finally, cognitive biases and self-disorders significantly predicted psychosis proneness.
