three-quarters (47% of the 65%) of men and half (21% of the 42%) of women with
personality disorders had antisocial personality disorder.
A smaller national survey conducted in the UK in 1997 (Singleton et al. 1997) involving
1,250 male remand, 1,254 male sentenced, 218 female remand and 676 female
sentenced prisoners found a higher prevalence of personality disorder and psychosis.
The prevalence of personality disorder in men was found to be 78% in remand prisoners
and 64% in sentenced prisoners and in women the prevalence was found to be 50%.
The prevalence of psychosis was 7% in male sentenced, 10% in male remand and 14%
in female prisoners. Neurotic disorders was also examined and it was found that the
prevalence was 59%, 40%, 76% and 63% in male remand, male sentenced, female
remand and female sentenced prisoners respectively.
The studies reported in this review involving 23,000 prisoners were from different
countries 68 , but the country with the second highest percentage – one quarter of all
prisoners – was the UK. So from this, Singleton‟s study, and from anecdotal evidence it
is likely that these findings apply to local prisons. Nevertheless, even if the prevalence
of mental illness in local prisoners is different from that reported in these studies, it will
still mean that there is a high number of local prisoners in need of mental health care.
Assuming that the local prisons are full to capacity and that the prevalence of psychotic
illnesses, major depression and personality disorder obtained from the international
review apply to the population of all three prisons, then Table 331 gives the estimated
number of male prisoners in each prison. It is likely that the prevalence of mental illness
in Full Sutton is higher than Wolds, Everthorpe or Hull as Full Sutton only holds category
A and B prisoners, whereas Wolds and Everthorpe only holds category C prisoners and
Hull is a local prison also holding remand prisoners and does not hold any category A
prisoners. The figures have been rounded to the nearest 5.

There is a policy in the Hull prison to move acute mentally prisoners out within 14 days
to specialist mental health services. Therefore, this will have an influence on the
prevalence of some mental health conditions in that prison. This policy only applies to

(280), Netherlands (450), New Zealand (1,431), Norway (41), Spain (99), Sweden (103), UK (5,548) and
