Article Synopsis
  • Many people who hear voices and are affected by trauma experience symptoms of both PTSD and auditory verbal hallucinations, which can be directly or indirectly related to their traumatic experiences.* -
  • Existing models for understanding PTSD and psychosis do not adequately explain the connection between these conditions and the experience of hearing voices, leading to limited treatment effectiveness.* -
  • A new integrative model called the trauma-related voices (TRV) model has been developed to explore the complex relationships between trauma and voice hearing, suggesting future research directions for improved treatment strategies.*

Objectives: Post-traumatic stress is common among people who hear voices (auditory verbal hallucinations), many of whom hear trauma-related voices, whereby voice content is related to past trauma. Preliminary evidence suggests that imagery rescripting (ImRs) may more effectively reduce post-traumatic stress and voices compared to treatments that are based on existing models of PTSD or positive symptoms. No known studies have explored the potential maintaining factors of trauma-related voices in relation to ImRs.

Background: A range of traumas have been linked to voices (auditory verbal hallucinations) and unusual perceptual experiences (UPEs) in other perceptual-sensory domains. Models of PTSD and positive symptoms of psychosis are insufficient in explaining the relationship between trauma and voices. The trauma-related voices (TRV) model was developed to generate novel research in this area.

Background: Most voice hearers report childhood trauma. Many voice hearers report comorbid post-traumatic stress symptoms and that the content of their voices (auditory verbal hallucinations) is directly (voices repeat phrases spoken by perpetrators) or indirectly (voice content and trauma is thematically similar) related to their trauma. The factors that maintain trauma-related voices are unknown, and there is limited research in this area.

Purpose Of Review: This review describes imagery rescripting (ImRs) and its clinical application to anxiety disorders and obsessive-compulsive disorder (OCD). Variations in ImRs delivery, clinical evidence, and theories of potential mechanisms of change are also reviewed. Finally, we propose a future research agenda.
