This article details the research methods and measurements used in conducting a population-based, case-control study of nearly lethal suicide attempts among persons aged 13-34 years, residing in Houston, Texas. From November 1992 to July 1995, we interviewed 153 case subjects presenting at one of three participating hospital emergency departments and used random digit dialing to identify 513 control subjects residing in the same catchment area in which cases were enlisted. Unlike most research in this area, this study was designed to extend our understanding of suicidal behavior and prevention activities beyond identification and treatment of depression and other mental illnesses. We discuss the overall strengths and weaknesses of our study design and conclude that this methodology is well suited for studying rare outcomes such as nearly lethal suicide.
本文详细介绍了在德克萨斯州休斯顿市开展的一项针对13至34岁人群中近乎致命自杀未遂事件的基于人群的病例对照研究中所使用的研究方法和测量手段。从1992年11月至1995年7月，我们对在三家参与研究的医院急诊科之一就诊的153名病例受试者进行了访谈，并使用随机数字拨号法确定了513名居住在招募病例的同一集水区内的对照受试者。与该领域的大多数研究不同，本研究旨在将我们对自杀行为和预防活动的理解扩展到抑郁症和其他精神疾病的识别与治疗之外。我们讨论了研究设计的总体优缺点，并得出结论，这种方法非常适合研究近乎致命自杀等罕见结果。
