Suicide

Harvard Unversity -  As a leading researcher on suicide, Matthew K. Nock knows the subject’s grim statistics by heart. Suicide is the second-leading cause of death for Americans aged 10 to 34, trailing only accidents. It claims more lives around the world each year than war, genocide, homicide, and all other violence combined. And 50 percent of people who died by suicide saw a clinician in their final month, according to multiple studies in recent decades, including Nock’s own research.

For Nock, that last statistic is both agonizing and motivating. Some might take it to mean that the warning signs of suicide are imperceptible or think that suicide is somehow inevitable for those in the grips of extreme suffering. Nock, who is both a researcher and a licensed clinician, reads the statistic as a tragic gap in a clinical-care system rooted in scheduled therapy appointments, which can fail to detect the highly variable — and fleeting — nature of suicidal thoughts.

But two new statistics make Nock, the Edgar Pierce Professor of Psychology, cautiously optimistic: In a multiyear study of 600-plus high-risk adults and adolescents, his lab predicted 75 percent of suicide attempts and 87 percent of suicide-related events in the week before they occurred. (Suicide-related events refer to attempts as well as hospitalizations to prevent attempts.)
