High-risk mentally disordered offenders present a diverse array of clinical characteristics. To contain and effectively treat this heterogeneous population requires a full understanding of the group's clinical profile. This study aimed to identify and validate clusters of clinically coherent profiles within one high-risk mentally disordered population in the UK.
Latent class analysis (a statistical technique to identify clustering of variance from a set of categorical variables) was applied to 174 cases using clinical diagnostic information to identify the most parsimonious model of best fit. Validity analyses were performed.
Three identified classes were a 'delinquent' group (n = 119) characterised by poor educational history, strong criminal careers and high recidivism risk; a 'primary psychopathy' group (n = 38) characterised by good educational profiles and homicide offences and an 'expressive psychopathy' group (n = 17) presenting the lowest risk and characterised by more special educational needs and sexual offences.
Individuals classed as high-risk mentally disordered offenders can be loosely segregated into three discrete subtypes: 'delinquent', 'psychopathic' or 'expressive psychopathic', respectively. These groups represent different levels of risk to society and reflect differing treatment needs.
高危精神障碍罪犯表现出多种多样的临床特征。为了控制和有效治疗这一异质群体，需要充分了解该群体的临床特征。本研究旨在英国的一个高危精神障碍人群中确定和验证临床一致特征的聚类。
使用临床诊断信息对 174 例患者进行潜在类别分析（一种从一组分类变量中识别方差聚类的统计技术），以确定最佳拟合的最简约模型。进行了有效性分析。
三个确定的类别是“犯罪”组（n=119），其特征是教育历史不佳、犯罪生涯强和高累犯风险；“原发性精神病”组（n=38），其特征是良好的教育概况和杀人罪；以及“表达性精神病”组（n=17），风险最低，特征是更多的特殊教育需求和性犯罪。
被归类为高危精神障碍罪犯的个体可以大致分为三个不同的亚型：“犯罪”、“精神病”或“表达性精神病”。这些群体代表了对社会的不同风险程度，并反映了不同的治疗需求。
