Two influential research reviews, one published in 1970 and the other in 1990, concluded that about 15 percent of people diagnosed with depression will end up killing themselves.
A new study indicates that this widely cited figure considerably overstates the suicide risk among depressed people. Their actual suicide risk ranges from 2 percent to 8.6 percent, according to the study, which appears in the December American Journal of Psychiatry. Around 1 percent of the general population in the United States commits suicide.
