Imagery Interventions for Auditory Vocal Hallucinations

Summary

This study explores the feasibility, acceptability, and effectiveness of four imagery intervention techniques (metacognitive imagery intervention, imagery rescripting, promoting positive imagery and competing imagery task) for auditory vocal hallucinations using four single case series with an A-B-A within subject design.

Conditions

• Auditory Hallucination
• Hearing Voices When No One is Talking
• Psychosis

Interventions

BEHAVIORAL

Imagery intervention for voice hearing (meta-cognitive imagery rescripting)

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.

BEHAVIORAL

Imagery intervention for voice hearing (promoting positive imagery de novo)

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.

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 promoting positive imagery de novo. Consolidation (2 sessions): Relapse prevention strategies are practiced before the end of intervention.

BEHAVIORAL

Imagery intervention for voice hearing (visuospatial working memory tasks)

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.
