The commonest disorder being substance and alcohol use disorders (42.0%). 23.3% of prisoners were diagnosed with current psychotic, bipolar, depressive and anxiety disorders. 46.1% were diagnosed with antisocial personality disorder. The majority of prisoners diagnosed as having an Axis 1 disorder in this study, were neither diagnosed nor treated in prison.

There is a high prevalence of mental disorders among prisoners in a prison population in Durban, South Africa. The majority of these prisoners are untreated in prison, related to non detection of the mental disorder. Greater mental health awareness and provision of mental health services focusing on staff training programmes to detect mental illnesses are needed and further research is recommended throughout South Africa.
