Abstract
Key Words: Schizophrenia; Auditory hallucinations; Unusual voices; Daily activities; Virtual reality
Background: Auditory hallucinations often influence schizophrenia
patients in many aspects. In order to develop effective
behavioral interventions for overcoming enduring auditory
hallucinations, it is necessary to understand how the annoying
symptom affects the daily lives of the patients. This
study evaluated the effect of hearing unusual voices on performing
the activities of daily life in schizophrenia patients.
Methods: Eighteen hallucinating patients, 18 nonhallucinating
patients and 20 normal controls performed the virtual
daily-life task of packing 8 items for travel under 3 conditions:
(1) without unusual voices and without avatars, (2) with
unusual voices and without avatars and (3) with unusual
voices and with avatars. Task completion time and the number
of times the packing list was checked were recorded as
a measure of the task performance. Results: When exposed
to unusual voices without avatars, hallucinating patients
checked the packing list fewer times than nonhallucinating
patients, and they required longer to complete the task, as
positive and negative symptoms were worse. Subjective responses
to unusual voices were stronger in hallucinating patients
than in nonhallucinating patients. Conclusions: Daily-
life activities of hallucinating patients may be less easily
influenced by odd auditory stimuli in a nonsocial situation
than those of nonhallucinating patients; however, hallucinating
patients may feel more strongly affected by unusual
voices. To better evaluate and thereby understand the difficulties
faced by hallucinating patients in their daily life, the
discrepancies between objective and subjective measures
as well as social situations should be taken into consideration.
