Under conditions of severe civil disturbance there was no increase in acute psychotic illness, & the suicide rate was unchanged. 217 patients presenting with psychiatric symptoms were interviewed as were 40 referral patients. Symptoms were more likely to be developed by the unemployed while social isolation, youth, & age did not appear to increase risk. Those developing symptoms tended to have a short-lived normal anxiety reaction or a repeat of a previous illness pattern. (25 refs.) (RM)
