Metacognitive beliefs, beliefs about voices and affective symptoms in patients with severe auditory verbal hallucinations.

Objectives: This study explores associations between metacognitive beliefs and beliefs about voices in patients with severe auditory verbal hallucinations, and their hypothesized relationship with levels of depression and anxiety. Furthermore, it was hypothesized that metacognitive beliefs are better able to explain differences in levels of depression and anxiety, than beliefs about voices.

Design: Cross-sectional data were obtained from baseline measurements of a randomized controlled trial.

Initial evaluation of the effects of competitive memory training (COMET) on depression in schizophrenia-spectrum patients with persistent auditory verbal hallucinations: a randomized controlled trial.

Objectives: This study investigates whether depression can be ameliorated by weakening the associations between auditory verbal hallucinations and easily activated networks with negative self-evaluations, by strengthening the access to competing memories of positive self-esteem. Design.  A randomized controlled clinical trial comparing competitive memory training (COMET) with treatment as usual (TAU) in schizophrenia patients with persistent auditory hallucinations.
