Study: NCT05603260

Intervention type: BEHAVIORAL
Group type: OTHER
Intervention: Imagery intervention for voice hearing (meta-cognitive imagery rescripting)
Description: The participants receive intervention for a period of 3 weeks, 6 sessions of 60 minutes.~In-depth identification of images (2 sessions): Identifying imagery which is related to the auditory vocal hallucinations, constructing a micro-formulation with the participant along the lines of regular Cognitive Behavioural Therapy. In this micro-formulation, first triggers of problematic imagery are identified, both quality and appraisals of this image are identified. Subsequent maladaptive behaviour and possible links with earlier experiences are described, as well as maintaining factors.~Imagery intervention (2 sessions): The imagery intervention consists of meta-cognitive imagery rescripting.~Consolidation (2 sessions): Relapse prevention strategies are practiced before the end of intervention.
