Studies report that in the U.K., among men with severe mental illness (SMI), those of black Caribbean ethnicity display increased risk of aggressive behaviour, criminal convictions, and schizophrenia. The study aimed to compare aggressive behaviour and criminal convictions among men with SMI of white British, black Caribbean and black African ethnicity, and to explore factors associated with differences across ethnicities.
Sample 1 included 1,104 male inpatients with SMI. Sample 2 included a representative sub-sample of 165 who completed interviews, and authorized access to medical and criminal files. Ethnicity was self-ascribed.
Staff-rated violence prior to admission, self-reported aggressive behaviour, and convictions for non-violent and violent crimes differed among men with SMI of different ethnicities. Relative to men with SMI of white British ethnicity, those of black African ethnicity showed decreased risk of aggressive behaviour, and those of black Caribbean ethnicity showed elevated risk of convictions for non-violent, and marginally, for violent crimes. Relative to men with SMI of black African ethnicity, those of black Caribbean ethnicity showed elevated risk of aggressive behaviour and criminal convictions. Proportionately more of the men of both black African and black Caribbean ethnicity, than those of white British ethnicity, presented schizophrenia spectrum disorders. Multivariate analyses failed to identify factors that would explain differences in aggressive behaviour, and criminal convictions across ethnic groups.
Differences in four different measures of aggressive and antisocial behaviour among men with SMI of different ethnicities were observed but factors associated with these differences were not found.
研究报告称，在英国，患有严重精神疾病（SMI）的男性中，加勒比裔黑人的攻击行为、犯罪定罪和精神分裂症风险增加。本研究旨在比较白种英国、加勒比黑人和非洲黑人种族的 SMI 男性的攻击行为和犯罪定罪，并探讨与种族差异相关的因素。
样本 1 包括 1104 名患有 SMI 的男性住院患者。样本 2 包括完成访谈并授权访问医疗和犯罪记录的 165 名代表性亚样本。种族是自我归因的。
入院前工作人员评定的暴力、自我报告的攻击行为以及非暴力和暴力犯罪的定罪在不同种族的 SMI 男性中存在差异。与白种英国种族的 SMI 男性相比，非洲黑种人表现出较低的攻击行为风险，而加勒比黑种人表现出非暴力犯罪和边缘性暴力犯罪定罪的风险升高。与非洲黑种人 SMI 男性相比，加勒比黑种人 SMI 男性表现出较高的攻击行为和犯罪定罪风险。患有 SMI 的非洲黑人和加勒比黑种人比白种英国种族的人更有可能出现精神分裂症谱系障碍。多变量分析未能确定可解释不同种族群体之间攻击行为和犯罪定罪差异的因素。
观察到不同种族的 SMI 男性在四种不同的攻击和反社会行为测量指标上存在差异，但与这些差异相关的因素尚未找到。
