To investigate the relationship between the four-facet model of PCL-R psychopathy and violence in a community-based sample of Australian men with schizophrenia-spectrum disorders.
A community sample of 94 males with schizophrenia-spectrum disorders was recruited from mental health services within Victoria, Australia. Psychopathy was measured using the PCL-R. Measures of substance misuse and lifetime violence were also administered.
PCL-R-total, Facets 2, 3, and 4 scores and substance misuse (DAST) scores were predictive of Violent versus Non-Violent group membership. The regression equation indicated that the predictive validity of PCL-R scores remained significant after controlling for substance misuse. An additional regression indicated that only Facets 3 and 4 were significant in predicting violence group membership.
Psychopathy (particularly the antisocial and behavioural components) was associated with lifetime violence, even after controlling for substance misuse. These findings have implications for the assessment, treatment, and management of health clients with schizophrenia-spectrum disorders.
在澳大利亚基于社区的精神分裂症谱系障碍男性样本中，调查 PCL-R 精神变态的四面模型与暴力之间的关系。
从澳大利亚维多利亚州的精神卫生服务机构招募了一个社区样本，其中包括 94 名患有精神分裂症谱系障碍的男性。使用 PCL-R 测量精神变态。还进行了物质滥用和终生暴力的测量。
PCL-R 总分、因子 2、3 和 4 分数以及物质滥用（DAST）分数预测了暴力与非暴力组别的成员身份。回归方程表明，在控制物质滥用后，PCL-R 分数的预测效度仍然显著。另外一个回归表明，只有因子 3 和 4 在预测暴力组别的成员身份方面具有显著意义。
即使在控制物质滥用的情况下，精神变态（特别是反社会和行为成分）也与终生暴力有关。这些发现对评估、治疗和管理患有精神分裂症谱系障碍的健康患者具有重要意义。
