To examine relationships between suicidal ideation, self-harm, and suicide attempts, including the timing of the phenomena.
The British National Psychiatric Morbidity Survey (NPMS) 2000, a randomised cross-sectional survey of the British population (n=8,580), included detailed questions about suicidal phenomena.
Suicidal phenomena were common in the survey population: a fifth had experienced tedium vitae, and nearly one in six had had death wishes or considered suicide. 4.4% of the study population had attempted suicide at some time. The relationships between individual elements of suicidality, though not absolute, were strong. The relationships tended to be hierarchical. The results suggested that suicidal thinking represents a strong indicator of vulnerability to suicidal acts, less so to self-harm. Although suicidal phenomena were more common in women, the relationship of the different elements were not affected by gender.
Studies in non clinical populations allow full appreciation of the nature and burden of suicidality. The topic of suicide is sensitive, so there may have been under-reporting, although the level of missing data was around 0.1%. Nevertheless, the sample was large and closely representative of the whole British populace.
Suicidality is common in the British population. The strong relationships between elements of suicidality are clinically important.
研究自杀意念、自残和自杀企图之间的关系，包括这些现象的发生时间。
2000 年英国全国精神疾病发病率调查（NPMS）是一项针对英国人群（n=8580）的随机横断面调查，其中包括关于自杀现象的详细问题。
自杀现象在调查人群中很常见：五分之一的人曾经历过生活乏味，近六分之一的人曾有过死亡愿望或考虑过自杀。研究人群中有 4.4%的人曾在某个时候尝试过自杀。尽管不是绝对的，但自杀意念的各个要素之间存在着强烈的关系。这些关系往往是分层的。结果表明，自杀思维是自杀行为易感性的有力指标，对自残行为的指示性则较弱。尽管自杀现象在女性中更为常见，但不同要素之间的关系不受性别影响。
在非临床人群中的研究可以充分了解自杀意念的性质和负担。自杀是一个敏感的话题，因此可能存在报告不足的情况，尽管数据缺失率约为 0.1%。然而，样本很大，并且与整个英国人口密切相关。
自杀意念在英国人群中很常见。自杀意念各要素之间的强烈关系在临床上很重要。
