Objectives: To investigate the epidemiological characteristics of antisocial personality disorder (ASPD) in young men in Chengdu and explore the characteristics and risks of violence.
Methods: Stratified random sampling was used to conduct a self-assessment questionnaire survey in 4 108 males aged from 18 to 34 in Chengdu, including general demographic characteristics, structured clinical interview for the diagnostic and statistical manual of mental disorders-Ⅳ axis Ⅱ disorders (SCID-Ⅱ) personality disorder screen questionnaire, violence questionnaire, psychosis screening questionnaire (PSQ), Alcohol Use Disorders Identification Test (AUDIT) and drug use. χ2 test, univariate and multivariate logistic regression were used for analysis and odds ratio (OR) was calculated.
Results: The positive rate of ASPD was 5.91%, which was associated with young age, unmarried, unemployment state, low educational level, violent behavior, psychotic symptoms, alcohol and drug use (P<0.05). Young men with ASPD also had a risk (P<0.05) of violence (OR was 8.51), multiple violence (OR was 16.57), injury (OR was 6.68), intentional violence (OR was 11.41), etc., the risk decreased after controlling for psychotic symptoms and substance abuse, but was still statistically significant.
Conclusions: The risk of violence, severe violence and intentional violence in young men in Chengdu is high, and psychotic symptoms and substance abuse increase the risk of ASPD violence and relate characteristics.
目的: 了解成都地区青年男性反社会型人格障碍（antisocial personality disorder，ASPD）的流行病学特点，探究其暴力行为的特征及风险。方法: 采用分层随机抽样方法，对成都地区4 108名18~34岁男性进行自评问卷调查，内容包括一般人口学特征、精神障碍诊断与统计手册-Ⅳ轴Ⅱ障碍临床定式检查（structured clinical interview for the diagnostic and statistical manual of mental disorders-Ⅳ axis Ⅱ disorders，SCID-Ⅱ）人格障碍筛查问卷、暴力行为问卷、精神病筛查问卷（psychosis screening questionnaire，PSQ）、酒精使用障碍筛查量表（Alcohol Use Disorders Identification Test，AUDIT）及毒品使用情况。使用χ2检验、单因素及多因素logistic回归进行分析，并计算比值比（odds ratio，OR）。结果: ASPD阳性率为5.91%，其与低龄、未婚、无工作、低受教育程度、暴力行为、精神病性症状、酒精与毒品使用均有关联（P<0.05），同时ASPD在暴力行为（OR为8.51）、多次暴力（OR为16.57）、致人受伤（OR为6.68）、故意暴力（OR为11.41）等方面存在风险（P<0.05），控制精神病性症状、物质滥用后这些风险有所下降，但仍有统计学意义。结论: 成都青年男性发生暴力行为、严重暴力、故意暴力的风险高，且精神病性症状及物质滥用会增加ASPD暴力行为及相关特征的风险。.
