|Researchers built maps of connections among students and teachers.|
Researchers studied 10,291 students at 38 high schools in North Dakota and upstate New York; two-thirds were in communities of fewer than 50,000. Students were asked to name up to seven of their closest friends and seven adults they trusted. Researchers used that information to build maps of the students' social networks, Carey reports.
The researchers found, as they expected, that students who were more isolated from their peers were more likely to commit suicide. But they found it particularly interesting that connections to trusted adults also made a big difference, Carey reports.
