(Seattle, WA)  --  A survey conducted in collaboration among multiple state agencies shows the number of Washington teens who have considered suicide is on the rise.  The 2016 Washington state Healthy Youth Survey shows there's been a six-percent increase over the past decade of eighth and tenth-grade students who have considered suicide, and an eight-percent increase among 12th-graders.  The survey shows girls were more likely to contemplate and attempt suicide than boys.  The Healthy Youth Survey is taken among sixth, eighth, tenth and 12th-grade students every two years, although sixth-graders aren't asked questions about suicidal feelings and actions.
