Child abuse and voice hearing: Finding healing through EMDR

Auditory verbal hallucinations in schizophrenia and post-traumatic stress disorder: common phenomenology, common cause, common interventions?

Auditory verbal hallucinations (AVH: ‘hearing voices’) are found in both schizophrenia and post-traumatic stress disorder (PTSD). In this paper we first demonstrate that AVH in these two diagnoses share a qualitatively similar phenomenology. We then show that the presence of AVH in schizophrenia is often associated with earlier exposure to traumatic/emotionally overwhelming events, as it is by definition in PTSD. We next argue that the content of AVH relates to earlier traumatic events in a similar way in both PTSD and schizophrenia, most commonly having direct or indirect thematic links to emotionally overwhelming events, rather than being direct re-experiencing. We then propose, following cognitive models of PTSD, that the reconstructive nature of memory may be able to account for the nature of these associations between trauma and AVH content, as may threat-hypervigilance and the individual’s personal goals. We conclude that a notable subset of people diagnosed with schizophrenia with AVH are having phenomenologically and aetiologically identical experiences to PTSD patients who hear voices. As such we propose that the iron curtain between AVH in PTSD (often termed ‘dissociative AVH’) and AVH in schizophrenia (so-called ‘psychotic AVH’) needs to be torn down, as these are often the same experience. One implication of this is that these trauma-related AVH require a common trans-diagnostic treatment strategy. Whilst antipsychotics are already increasingly being used to treat AVH in PTSD, we argue for the centrality of trauma-based interventions for trauma-based AVH in both PTSD and in people diagnosed with schizophrenia.

Treating trauma in psychosis with EMDR: a pilot study

BACKGROUND

Initial studies have shown that posttraumatic stress disorder (PTSD) can be effectivelytreated in patients with a psychotic disorder. These studies however used adapted treatment protocols, avoided direct exposure to trauma related stimuli or preceded treatment with stabilizing techniques making treatment considerably longer in duration.

METHOD

An open trial in which adult subjects with a psychotic disorder and a comorbid PTSD (n = 27) received a maximum of six Eye Movement Desensitization and Reprocessing (EMDR) therapy sessions. PTSD symptoms, psychotic symptoms and additional symptoms were assessed at baseline and end-of-treatment.

RESULTS

The dropout rate was 18.5 percent (five subjects). Only five of the twenty-two completers (22.7%) still met criteria for PTSD after treatment. PTSD symptoms, auditory verbal hallucinations, delusions, anxiety, depression, and self-esteem all improved significantly. Paranoid ideation and feelings of hopelessness did not improve significantly. Treatment did not lead to symptom exacerbation in subjects. There were no adverse events, such as suicide attempts, self-mutilation, aggressive behavior or admission to a general or psychiatric hospital.

CONCLUSIONS

This pilot study shows that a short EMDR therapy is effective and safe in the treatment of PTSD in subjects with a psychotic disorder. Treatment of PTSD has a positive effect on auditory verbal hallucinations, delusions, anxiety symptoms, depression symptoms, and self-esteem. EMDR can be applied to this group of patients without adapting the treatment protocol or delaying treatment by preceding it with stabilizing interventions.
