The authors have found high rates of psychosis among prisoners, as well as major depression and antisocial personality disorder, in both men and women.

They point out that psychotic illness and major depression are between two and four times more common among prisoners than in the general population. The rate of psychosis among prisoners is 4%, the rate of major depression between 10 and 12%. Antisocial personality disorder affects half of male prisoners and a fifth of female prisoners.
