Abstract
Suicidal ideation/behaviour (SIB) and psychosis are highly associated phenomena. We propose that psychosis, for some, may be consequential to SIB.
More specifically we hypothesise that psychosis may serve to externalise
internally generated and self-directed threat among those experiencing SIB.
Using prospective data from a Danish population cohort, we first sought to
test the temporal occurrence of suicidal behaviour and psychotic disorder.
Next, using cross-sectional epidemiological survey data (UK), we sought to
demonstrate that psychotic experiences (PEs) were more commonly
reported by those who experienced SIB and that the strength of the
association varied according to (i) SIB recency and (ii) severity. Chi-square
comparison tests on the Danish data revealed that suicidal behaviour was
statistically more likely to precede (41.4%) rather than follow psychotic
disorder (20.7%). Regression analyses of the UK data indicated that individuals who thought about suicide in their lifetime were up to eight times
more likely to experience specific PEs while those who thought about and
attempted suicide in their lifetime and in the year of assessment were up to
48 times more likely to experience PEs, compared to SIB free members of
the population. The findings provide preliminary support for a novel suicidal
drive hypothesis for psychosis.
