For decades, researchers and clinicians widely cited a figure suggesting that every suicide death leaves behind roughly six survivors, an estimate often traced to pioneering suicidologist Edwin Shneidman but that predated any empirical basis. In 2018, Julie Cerel, PhD, and her team at the University of Kentucky’s Suicide Prevention and Exposure Lab published a landmark epidemiological study demonstrating that a single suicide impacts approximately 135 individuals, a finding that changed the field’s understanding of how many people are exposed to a death by suicide each year.
That work prompted Cerel to shift her research focus from bereavement to suicide exposure, to better serve and capture the full population of people affected by suicide. “We found that knowing someone, especially being close to someone who has died by suicide, becomes a risk factor for a person’s own mental health behaviors and future suicidal ideation,” she said. “We proposed the idea that suicide survivorship exists on a continuum. There is a handful of people—mostly family, close friends, or clinicians—who are profoundly influenced and identify as survivors for the rest of their lives.”
Cerel talks about the need for a broader approach to suicide prevention, intervention, and postvention in reducing people’s risk for suicide, talking with patients about exposure to others suicide, and providing the kind of support clinicians need if they lose a patient to suicide.
