Auditory verbal hallucinations (AVH) are commonly reported as source of distress, disability and mortality in schizophrenia. Despite proven efficacy of antipsychotics, many patients still experience drug-refractory AVH. It has been postulated that AVH is maintained by negative emotions. Yet, little is known about the temporal relationship and underlying mechanisms between negative affect and AVH. Utilizing both an ecologically-validated method and brain imaging technique, this study aims to uncover the role of emotions in the maintenance of psychotic symptoms.
