P. Chadwick et P. Trower, COGNITIVE THERAPY FOR PUNISHMENT PARANOIA - A SINGLE-CASE EXPERIMENT, Behaviour research and therapy, 34(4), 1996, pp. 351-356
There is growing agreement that at least certain kinds of delusions de
fend against negative self-evaluation, and in consequence that cogniti
ve therapy for delusions needs to address issues of self-evaluation mo
re explicitly. However, in practice it can be difficult to enable clie
nts to see the connection between delusions and self-esteem. The prese
nt single-case study exemplifies the conceptual and practical applicat
ion of cognitive therapy for individuals who are both paranoid and hav
e strong negative self-evaluative beliefs. A multiple-baseline approac
h is used, whereby one man's negative self-evaluative belief and two p
aranoid delusions are challenged sequentially. Conviction in two of th
e three beliefs changes at the point of intervention; conviction in th
e third changes prior to intervention. We discuss the details of the c
ase, as well as the wider implications for cognitive approaches to del
usions.
