In this comparative study with a control group of prisoners, psychiatr
ic morbidity was measured in two groups of sentenced prisoners, each g
roup completing the GHQ-30 and 21-item Beck Depression inventory (BDI)
. Group 1 consisted of 40 segregated HIV-positive prisoners and group
2 a matched control group in the main prison who had no history of HIV
seropositivity. All members of group 1 had a history of intravenous d
rug abuse. The mean GHQ30 and BDI scores were significantly higher in
group 1, and 90% of group 1 were psychiatric 'cases' compared with jus
t over 42% of group 2. Levels of psychiatric morbidity present in a th
ird group. consisting of HIV-positive prisoners who had not been segre
gated (prison authorities were unaware of their seropositivity) are an
interesting pointer for further research.
