The compulsory detention of males of different ethnic groups, with special reference to offender patients.

Compulsory detention rates of white, West Indian and Asian males under Part IV and Part V (offenders) of the 1959 Mental Health Act were compared: British-born West Indians and Asians were differentiated from migrants. Rates for Asians were similar to those for whites, but West Indians were significantly over-represented amongst compulsory detentions, especially as offender patients. A high total number of admissions and diagnostic differences accounted for the excess of West Indians admitted under Part IV, but not Part V.
