Question How frequently and when do suicidal ideation, plan, and attempt emerge in adolescence and young adulthood?
Findings In a cross-sectional, epidemiological study of 1180 adolescents and young adults from a random community sample in Germany, 10.7%, 5.0%, and 3.4% of participants reported lifetime suicidal ideation, plan, and attempt, respectively. The cumulative incidence of suicidal behavior increased after age 10 years more strongly among female than male participants, and the transition from ideation to action occurred mostly during the same year.
Meaning Adolescence and young adulthood are critical developmental periods for the onset of suicidal behavior, with a short time for targeted interventions to disrupt the ideation-to-action pathway.
