The overwhelming number of these schizophrenic patients are also inpatients
(14/15). It may be reasonable to infer that those diagnosed as su ering from
V
schizophrenia/psychosis, being cared for in hospital and who are well enough to
complete psychometric assessments are generally concerned not to be seen as
worse than they are, and hence do not exaggerate their psychopathology. It may be
that some participants of this subgroup are keen to portray themselves in a negative
way as a means of sustaining their dependence on supportive care. This proposition
is supported by a supplementary t test comparing dependent scores of the ve
schizophrenia/psychotic in-patients in the high Debasement group (M = 89.2) with
the 14 similar participants in the not abnormal group (M = 64.3). This reveals
signi cantly higher scores among the ve high Debasement group in-patient
participants (t = 2.32, p = .033). In general terms, for the majority it can be argued
that it is not their diagnosis that predicts Z but their circumstances. However there
appears to be a minority who are likely to display a strength of motivation to meet
psychological needs through representing themselves negatively, o ering some
V
support for the pathogenic model of malingering rejected by Rogers (1990b).
A second and related issue is to distinguish between those who fake bad as a
result of an adaptive motive to do so, and those who characteristically express
themselves and describe their experience in an exaggerated form. One possible way
of distinguishing those who are actively seeking to ‘fake bad’ from those who
perceive themselves to be su ering greatly, regardless of objective review, may be
V
the combination of Z and Histrionic, Narcissistic and Compulsive scales. The not
abnormal Debasement group had signicantly higher scores on these three scales,
a nding which concurs with research into faking good pro les on the MCMI-II
(Retzla et al., 1991).
V
The combination of high Z and low H, N and C might prove to be a useful
apparent and subtle means of identifying those who make deliberate e orts at
V
faking bad (high Z and very low H, N and C) and those who experience great need
(high Z but moderate H, N and C). If this is so, then there may be a means of
distinguishing between those with adaptional sources of malingering and those with
other motivations, and managing them accordingly.
