Abstract

The content of AVHs is a major predictor of distress. Although the relationship between mood and AVH content is considered of diagnostic relevance, research investigating the role of depression and anxiety in AVH content remains limited. This study investigated subtypes of negative AVH content, comprising critical, threatening, and self-harm commands in affective and non-affective psychosis. In addition, the study investigated relationships between negative, critical, threatening and self-harm related AVH content and depression and anxiety.

RESULTS showed that AVH content did not vary between affective and non-affective psychosis. Among affective voice-hearers, critical, threatening and self-harm content was predicted by anxiety. Whereas in non-affective voice-hearers, self-harm content was predicted by depression.

FINDINGS suggest that in affective psychosis, "mood" may be more relevant to whether people hear voices per se, given that by definition voices only arise in mood episodes, whereas anxiety appears to be important in influencing content. In contrast, anxiety and depression may have little influence over voice content in non-affective psychosis, with the exception of depression in self-harm commands. As such, anxiety should be considered in the formulation and treatment of negative AVHs in affective psychosis, and depression in non-affective voice-hearers with self-harm commands.
