Early detection and better coordination are needed to prevent teen suicide, according to a recent study.

In 2009, suicide was the second leading cause of death of Canadians aged 15 to 34. It is known that 90 percent of people who die by suicide suffer from a mental illness.

Although progress has been made in recent years, the matter of youth suicide in Quebec still needs to be more effectively addressed. Researchers from Douglas Mental Health University Institute and McGill University found that more lives could be saved through early detection and increased public awareness and information sharing among professionals.

"It is imperative to better train the public, via awareness campaigns, for instance," said researcher Johanne Renaud. "We must also better identify, treat, and coordinate services for youth at risk."

For the study, researchers collected data from 67 suicide completers ages 25 and under and matched them with 56 living control subjects. They evaluated their psychopathological profile and determined which services would have been appropriate by conducting a needs assessment. The team then compared these needs with what services were actually received.

They found that a majority of suicide victims had suffered from mental health problems. They were more likely than control subjects to be in need of services to address underlying substance use disorder, depression, and other suicide-related problems.

They also identified significant deficits with respect to training of professionals, coordination of services, and continuity of care.
