Study examines suicide contagion following celebrity deaths, opening avenues for prevention

New analysis fashions the fast and expansive unfold of suicidal behaviors following the suicides of Robin Williams in 2014, and of Kate Spade and Anthony Bourdain, which occurred three days aside in 2018.

Columbia College researchers developed a pc mannequin to look at the dynamics underlying suicide contagion. They discovered that each the 2014 and 2018 occasions led to giant will increase in suicidal thought and habits. The findings, which seem within the journal Science Advances, present a framework for quantifying suicidal contagion to raised perceive, forestall, and comprise its unfold.

“The mannequin we developed exhibits how suicide contagion, together with each suicidal ideation and deaths, spreads rapidly following the suicide deaths of celebrities whose lives and work are recognized and certain significant to giant parts of the inhabitants,” says Jeffrey Shaman, Ph.D., research co-author, interim dean of Columbia Local weather Faculty, and professor of environmental well being sciences at Columbia College Mailman Faculty of Public Well being.

Shaman is well-known for growing fashions of influenza and SARS-CoV-2. The Columbia researchers’ mannequin for suicide contagion has a construction just like fashions depicting different infectious methods, together with the variety of people able to transmitting the contagion and the variety of people prone to “an infection.”

There isn’t a single issue that causes suicide or suicidal ideation. Nonetheless, a portion of suicidal ideation has lengthy been attributed to social, or contagious, processes. Proximity to or familiarity with individuals who’ve ideated, tried, or died of suicide can induce suicidal ideation or makes an attempt amongst prone people.

In line with the CDC, suicide charges elevated 37% between 2000–2018 and decreased 5% between 2018–2020 earlier than returning to their peak in 2021.

The Columbia suicide contagion mannequin makes use of two information sources. First, whole weekly calls to the Nationwide Suicide Prevention Lifeline, at present often known as the 988 Suicide and Disaster Lifeline (988 Lifeline) was used as an estimate of suicidal ideation (988 Lifeline is a community of greater than 200 round the clock disaster name facilities that present confidential psychological well being disaster and counseling providers nationwide).

The second supply was derived from mortality information within the Nationwide Important Statistics System, managed by the Nationwide Heart for Well being Statistics.

The mannequin estimates that following the 2014 suicide occasion there was a pronounced enhance in suicide contagion charges, together with a thousand-fold enhance of the chance that an individual would start to ideate suicide following information of Williams’ demise by suicide.

The end result was a pronounced enhance of suicidal ideation, manifested in a spike in name quantity to 988 Lifeline. The 2018 case is analogous, though the magnitude of the suicide contagion price adjustments following information of the Spade and Bourdain suicides was roughly half.

Among the many two celeb suicide occasions, the variety of extra suicide deaths was roughly double following the 2014 Williams occasion, doubtlessly reflecting variations in communication and media consideration following every occasion and the extent of inhabitants reference to the deceased. In each the 2014 and 2018 simulations, the elevated charges of contagion lasted about two weeks earlier than returning to baseline ranges.

Ultimately, with additional research, researchers say the mannequin may present real-time estimations of suicide contagion and threat. Such estimates would require that 988 Lifeline name quantity and NVSS suicide deaths, have been out there in actual time; at present, they aren’t. Moreover, additional analysis is required to develop alternate fashions, together with those who simulate responses amongst particular communities and those who account for media and public well being outreach efforts.

“Finally, our goal is to work towards a degree the place a suicide contagion mannequin can inform a fast response geared at stopping suicide,” says Katherine Keyes, Ph.D., co-author of the paper, professor of epidemiology, and director of SPIRT, a brand new Columbia initiative that goals to catalyze public well being analysis collaborations to raised perceive the psychological well being disaster and establish options.
