The public health impact of psychopathy on violence has not previously been measured in the general population.
Psychopathy was measured using the Psychopathy Checklist:Screening Version (PCL:SV) in adults 16-74 years (n = 638) in households in England, Scotland and Wales in a two-phase survey which included self-reported measures of violence.
Participants with PCL:SV scores 11 or above demonstrated a prevalence of 2.1% (95% CI 1.2, 3.8) but accounted for 18.7% of violent incidents, a population-attributable risk of 16.6%, and demonstrated an exponential rise in reported violent incidents. Psychopathic traits correlated with victim injury, multiple victim subtypes and locations.
Psychopathy makes a substantial impact on violence among the general population despite a low prevalence. Explanations of this association include interpersonal difficulties due to psychopathic traits, fearlessness, thrill seeking, and antisocial lifestyle, but not impulsivity independent of antisocial lifestyle.
此前，在普通人群中尚未测量过精神病态对暴力的公共卫生影响。
在英格兰、苏格兰和威尔士的家庭中，对 16-74 岁的成年人（n=638）使用精神病态检查表：筛查版（PCL：SV）进行精神病态测量，该调查包括自我报告的暴力措施。
PCL：SV 得分 11 或以上的参与者的患病率为 2.1%（95%CI 1.2, 3.8），但占暴力事件的 18.7%，人群归因风险为 16.6%，并显示出报告的暴力事件呈指数增长。精神变态特征与受害者受伤、多种受害者亚型和地点有关。
尽管精神病态的患病率较低，但它对普通人群中的暴力行为仍有重大影响。这种关联的解释包括由于精神变态特征、无所畏惧、寻求刺激和反社会生活方式引起的人际困难，但不包括与反社会生活方式无关的冲动。
