Mediators of negative content and voice-related distress in a diverse sample of clinical and non-clinical voice-hearers.

Abstract

Negative content in hearing voices (i.e., auditory verbal hallucinations) has been associated with adverse clinical outcomes including voice-related distress. Voice appraisals and responding mindfully to voices are theorized to reduce voice-related distress. This study aimed in examine mediators of the negative content voice-related distress relationship in clinical (those who recently received input from mental health services) and non-clinical voice-hearers. One hundred and twenty-one adults (71.9% female; 35.5% mixed or non-white ethnic background) who hear voices were recruited online and completed self-report measures of negative content of voices, voice-related distress, mindfulness of voices, interpretation of loss of control, thought suppression and intrusion. Clinical voice-hearers had significantly higher levels of negative content, voice-related distress and interpretation of loss of control than non-clinical voice-hearers. A mindful approach to voices and interpretation of loss of control mediated the relationship between negative content and voice-related distress across the whole sample. Thought suppression and intrusion did not mediate the relationship. The results support the use of mindfulness-based psychological intervention to reduce voice-related distress. Further development of valid and reliable measures specifically relating to constructs of voice content, voice-related distress and voice suppression will support further research in this area.
