A cross-sectional study of auditory verbal hallucinations experienced by people with a diagnosis of borderline personality disorder.

Background The presence of auditory verbal hallucinations (AVH) does not currently feature in the main diagnostic criteria for Borderline Personality Disorder (BPD). However, there is accumulating evidence that a high proportion of BPD patients report longstanding and frequent AVH which constitute a significant risk factor for suicide plans and attempts, and hospitalisation. Aim This study addressed questions about the validity and phenomenology of AVH in the context of BPD. The longer-term aim is to facilitate the development and translation of treatment approaches to address the unmet need of this population. Method This was a cross-sectional study, combining phenomenological and psychological assessments administered in person and online. We explored the experiences of 48 patients with a diagnosis of BPD who were hearing AVH. Results Participants gave ‘consistent’ reports on the measure of AVH phenomenology, suggesting that these experiences were legitimate. Similar to AVH in a psychosis context, AVH were experienced as distressing and appraised as persecutory. AVH were found to be weakly associated with BPD symptoms. AVH were also rated highly as a treatment priority by the majority of participants. Conclusion The findings suggest that AVH is a legitimate and distressing symptom of BPD and a treatment priority for some patients. The relative independence of AVH from other BPD symptoms and emotional states suggests that psychological treatment may need to be targeted specifically at the symptom of AVH. This treatment could be adapted from Cognitive Behaviour Therapy, the psychological intervention that is recommended for the treatment of AVH in the context of psychosis.
