The researchers also found that suicide attempts during childhood and adolescence were linked to higher scores of depression at the time of the attempts, validating for the first time that young adults can reliably recall when they first attempted suicide.

Depression levels were higher at the time of the youths' reported first suicide attempts compared with their peers who had not attempted suicide. And Mazza found an increase in depression scores at the time of the attempt compared with depression scores the year before and after the attempt for the same child.

The National Institute on Drug Abuse funded the study. Other co-authors are Robert Abbott, UW educational psychology professor; and Richard Catalano, director, and Kevin Haggerty, assistant director, of UW's Social Developmental Research Group.
