Background. Determining the prevalence of psychiatric disorders among
remand populations has been made a priority in England and Wales. Diff
erences in legal process and psychiatric services in Scotland make sim
ilar research there important. Method. Demographic data were collected
on 389 prisoners, the Clinical Interview Schedule was completed and c
ognitive function assessed. Results. The prevalence of major psychiatr
ic disorders was low. Less severe symptoms were more common. The sampl
e was of average IQ, but low educational attainment. Reported drug abu
se was high. Conclusions. Few of those interviewed required hospital c
are, but other symptoms and drug-related problems may place heavy dema
nds on prison medical and psychiatric services.
