In this article we summarize findings from our program of research (th
e Oregon Adolescent Depression Project) as they pertain to the suicida
l behavior of older (14-18-year-old) adolescents. Specifically, we (a)
present information regarding the epidemiology of suicidal ideation a
nd suicide attempts (e.g., prevalence, incidence, onset age, methods,
severity); (b) describe the psychosocial characteristics associated wi
th past and future suicide attempts, in comparison to depression; (c)
discuss issues relevant to assessment and screening, including our dev
elopment of a new assessment instrument, the Life Attitudes Schedule;
(d) share recommendations gained from our experience in providing trea
tment for depressed adolescents, approximately 40% of whom had made a
suicide attempt; and (e) identify gaps in current knowledge for which
more research is needed.
