In the aftermath of a suicide, family and friends of the deceased sometimes turn to social media sites for clues as to why it may have happened.
But on a more hopeful note, the trails left on these sites may also serve as something of an early warning system that could help prevent some of these tragedies, according to researchers at Brigham Young University.
Reporting in the journal Crisis, the researchers say they sifted through millions of tweets gathered from all 50 states over three months, on the hunt for both direct discussions of suicide and keywords that are associated with a range of suicide risk factors.
Out of the millions of tweets on hand, they found 37,717 worrying tweets from 28,088 unique users with some location info available. They then determined each state’s ratio of such tweets, and found that these correlated strongly with each state’s actual suicide rate.
For instance, in Alaska, home to the highest suicide rate in the country, the researchers found 61 at-risk Twitter users, while in Texas, which has a slightly lower rate but a far larger population, more than 3,000 Twitter users were flagged as being at risk.
