The Accuracy of Prevalence Estimations for Suicide Attempts. How Reliably Do Adolescents and Young Adults Report Their Suicide Attempts?

Abstract

This study explores the accuracy of prevalence estimations for suicide attempts. Data came from the Early Developmental Stages of Psychopathology (EDSP) Study, a prospective community study (mean follow-up period was 42 months) of 3,021 respondents aged 14 to 24 years at the outset of the study. Suicide attempters are at least 1.6 times more likely to drop out than subjects with no suicide attempts and suicidal ideas. A total of 8% of all suicide attempters answered in the negative the depression-related gate questions of all surveys. One-third of all baseline suicide attempters did not report their suicide attempt again at the four years later assessment. In particular, 80% of all nonreporters were female, and almost 60% were aged 14-17 at baseline.
