Suicide attempt rates are usually reported as an annual statistic. However, annual rates may underestimate the cumulative prevalence of attempters since they ignore people whose attempts occurred in years other than the one examined. The authors studied the prevalence of suicide attempters over several years through data gathered from retrospective reports of college students. They found that 15% of the total sample studied (N=293) reported having attempted suicide at one time. This unexpectedly high rate suggests that suicidal behavior is a serious problem among college students and underlines the need for further retrospective studies of the prevalence of suicide attempters.
自杀未遂率通常作为年度统计数据进行报告。然而，年度比率可能会低估自杀未遂者的累积患病率，因为它们忽略了那些自杀未遂发生在被考察年份之外的人。作者通过从大学生回顾性报告中收集的数据，研究了多年来自杀未遂者的患病率。他们发现，在整个研究样本（N = 293）中，有15%的人报告曾有过一次自杀未遂行为。这一意外的高比率表明，自杀行为在大学生中是一个严重问题，并强调有必要对自杀未遂者的患病率进行进一步的回顾性研究。
