P. Chadwick et M. Birchwood, THE OMNIPOTENCE OF VOICES - A COGNITIVE APPROACH TO AUDITORY HALLUCINATIONS, British Journal of Psychiatry, 164, 1994, pp. 190-201
We offer provisional support for a new cognitive approach to understan
ding and treating drug-resistant auditory hallucinations in people wit
h a diagnosis of schizophrenia. Study 1 emphasises the relevance of th
e cognitive model by detailing the behavioural, cognitive and affectiv
e responses to persistent voices in 26 patients, demonstrating that hi
ghly disparate relationships with voices - fear, reassurance, engageme
nt and resistance - reflect vital differences in beliefs about the voi
ces. All patients viewed their voices as omnipotent and omniscient. Ho
wever, beliefs about the voice's identity and meaning led to voices be
ing construed as either 'benevolent' or 'malevolent'. Patients provide
d cogent reasons (evidence) for these beliefs which were not always li
nked to voice content; indeed in 31% of cases beliefs were incongruous
with content, as would be anticipated by a cognitive model. Without f
ail, voices believed to be malevolent provoked fear and were resisted
and those perceived as benevolent were courted. However, in the case o
f imperative voices, the primary influence on whether commands were ob
eyed was the severity of the command. Study 2 illustrates how these co
re beliefs about voices may become a new target for treatment. We desc
ribe the application of an adapted version of cognitive therapy (CT) t
o the treatment of four patients' drug-resistant voices. Where patient
s were on medication, this was held constant while beliefs about the v
oices' omnipotence, identity, and purpose were systematically disputed
and tested. Large and stable reductions in conviction in these belief
s were reported, and these were associated with reduced distress, incr
eased adaptive behaviour, and, unexpectedly, a fall in voice activity.
These changes were corroborated by the responsible psychiatrists. Col
lectively, the cases attest to the promise of CT as a treatment for au
ditory hallucinations.
