Abstract
The experience of hearing voices is common to an estimated 7% of the general population, with the presence of negative content being the best predictor of whether individuals will require clinical support. Whilst largely neglected in the literature to date, there are calls to consider the significance of voice content for reducing voice-related distress. However, no quantitative and comprehensive measure of voice content with suitability for research and clinical use exists. This pilot study aimed to demonstrate preliminary psychometric properties of a newly developed measure, the Perth Voice Content Questionnaire (PVCQ), designed to measure the intensity and themes of positively and negatively valenced voice content, primarily of the dominant voice. The PVCQ and measures of voice severity and related beliefs were completed by 47 voice-hearing participants. The measure was found to be internally consistent, loaded onto two distinct factors of positive and negative content, and these factors were associated with voice-related distress and negative beliefs about voices and positive beliefs about voices, respectively, indicating good validity. The PVCQ offers the first self-report measure of voice content, with preliminary psychometric properties indicating its suitability for clinical and research use.

Abstract
Auditory verbal hallucinations, or voice hearing, is increasingly understood as a common experience. Despite this, voice hearers still experience a great deal of stigma, which can have serious negative impacts on the person's experience of their voices, and their recovery. Research has demonstrated that healthcare professionals may be a major source of the stigma surrounding voice hearing, with service-level implications for the development and delivery of evidence-based interventions. Therefore, reducing this stigma is a critical intervention target. The purpose of this narrative review is to examine evidence for interventions aimed at reducing stigma towards people who hear voices, in populations of healthcare professionals, students, and the general public. The available evidence supports the use of anti-stigma interventions based around direct contact with voice hearers and education about voice hearing. However, further research is necessary in this area to confirm these findings.
