Affective and cognitive factors associated with hallucination proneness in the general population: the role of shame and trauma-related intrusions.

Introduction: Feelings of shame may be an important factor implicated in the onset and maintenance of hallucination (or hearing voices). Shame has been shown to increase trauma-related intrusions and avoidance and may reinforce negative beliefs about the self, which in turn may contribute to hallucinations in clinical and non-clinical populations. To our knowledge, no study has so far explored the role of shame in hallucination-proneness. Therefore, the main goal of the present study is to explore the mediation role of shame, trauma-related intrusions and avoidance in the association between childhood trauma and hallucination-proneness.Methods: Self-report questionnaires were used to assess past traumatic experiences, trauma-related symptoms, shame, and hallucination proneness in 175 participants from the general population.Results: Mediation analyses (joint-significance test and Monte Carlo test) showed that both shame and intrusions mediated the association between childhood trauma and hallucination-proneness.Conclusions: Our results reinforce the importance of considering previous experiences of trauma and trauma-related symptoms, including feelings of shame in individuals experiencing hallucinations. Moreover, this study reinforces previous studies showing some preliminary evidence that compassion-focused therapy, whose primary goal is to reduce shame by increasing self-compassion, could have a significant effect on voices whose content is hostile.
