To determine the rates of psychiatric disorder and personality variables in a sample of older people who had committed suicide and to compare the rates in a subgroup of this sample with those in a control group of people who died from natural causes.
Descriptive psychological autopsy study, including interviews with informants, of psychiatric and personality factors in 100 suicides in older people. Case-control study using subgroup of 54 cases and matched control group.
Four counties and one large urban area in central England, UK.
Individuals 60 years old and over at the time of death who had died between 1 January 1995 and 1 May 1998, and whose deaths had received a coroner's verdict of suicide (or an open or accidental verdict, where the circumstances of death indicated probable suicide). The control group was an age-and sex-matched sample of people dying through natural causes in the same time period.
ICD-10 psychiatric disorder, personality disorder and trait accentuation.
Seventy-seven per cent of the suicide sample had a psychiatric disorder at the time of death, most often depression (63%). Personality disorder or personality trait accentuation was present in 44%, with anankastic or anxious traits the most frequent. Depression, personality disorder, and personality trait accentuation emerged as predictors of suicide in the case-control analysis.
Personality factors, as well as depression, are important risk factors for suicide in older people.
确定自杀的老年人群样本中的精神障碍发生率及人格变量，并将该样本中的一个亚组与自然死亡的对照组人群的发生率进行比较。
描述性心理解剖学研究，包括对100例老年自杀者的 informant 进行访谈，以了解其精神和人格因素。采用54例病例亚组和匹配对照组的病例对照研究。
英国英格兰中部的四个县和一个大城市地区。
1995年1月1日至1998年5月1日期间死亡的60岁及以上个体，其死亡经验尸官判定为自杀（或死因情况表明可能为自杀的开放性或意外性判定）。对照组是同一时期因自然原因死亡的年龄和性别匹配的人群样本。
ICD - 10精神障碍、人格障碍和特质强化。
自杀样本中77%在死亡时患有精神障碍，最常见的是抑郁症（63%）。人格障碍或人格特质强化占44%，强迫或焦虑特质最为常见。在病例对照分析中，抑郁症、人格障碍和人格特质强化成为自杀的预测因素。
人格因素以及抑郁症是老年人自杀的重要危险因素。
