Outcome measures
Primary outcome
Assessments consist of acquiring verbatim repetitions of voices, voice-related
measures such as voice phenomenology, acceptance of the voices, and
impact on daily functioning, and hemispheric asymmetry during language
processing. These will be used to distinguish and characterise linguistic voice
subtypes, to examine working mechanisms underlying these voice-types, and to
assess the role of voice-type in treatment effectiveness of psychological
interventions.
Secondary outcome
n.v.t
Background summary
About 3% of the population experiences hallucinated voices that cause distress
to the extent that they seek help for it. Unfortunately, the numerous
psychological interventions for voice-hearing are hampered by small-to-modest
effect sizes, which may be due to an under-appreciation of the heterogeneity of
voice-hearing. Some voice-hearers typically hear voices that can be described
as *compact*, while others hear *expanded* voices. Each of these may have
differential underlying working mechanisms, in terms of hemispheric asymmetry
of language areas of the brain. Importantly, existing psychological
interventions may become much more effective if they are prescribed for the
type of voice they best target, rather than in the one-size-fits-all manner
they are delivered to date.
Study objective
1. Distinguish and characterise linguistic voice-types
2. Examine differential working mechanisms of voice-types
3. Exploratively evaluate the role of voice-type in treatment effectiveness
4. Disseminate the results to clinicians and voice-hearers
Study design
Participants will receive their psychological treatment as planned.
Participation in the study will not interfere with the treatment. Participants
will undergo a pre-assessment, and a post-assessment.
Study burden and risks
The study is deemed to pose minimal burden on participants.
