There has been major concern about the 'over-representation' of Black and ethnic minority groups amongst people detained under the Mental Health Act (MHA). We explored the effect of patient ethnicity on detention following an MHA assessment, once confounding variables were controlled for.
Prospective data were collected for all MHA assessments over 4-month periods in the years 2008, 2009, 2010 and 2011 each in three regions in England: Birmingham, West London and Oxfordshire. Logistic regression modelling was conducted to predict the outcome of MHA assessments - either resulting in 'detention' or 'no detention'.
Of the 4423 MHA assessments, 2841 (66%) resulted in a detention. A diagnosis of psychosis, the presence of risk, female gender, level of social support and London as the site of assessment predicted detention under the MHA. Ethnicity was not an independent predictor of detention.
There is no evidence for that amongst those assessed under the MHA, ethnicity has an independent effect on the odds of being detained.
《精神健康法》（MHA）规定被拘留人群中黑人和少数族裔群体“占比过高”，这一问题引发了广泛关注。在控制混杂变量后，我们探究了患者种族对依据《精神健康法》评估后被拘留情况的影响。
收集了2008年、2009年、2010年和2011年各4个月期间在英格兰三个地区（伯明翰、西伦敦和牛津郡）所有依据《精神健康法》进行评估的前瞻性数据。进行逻辑回归建模以预测依据《精神健康法》评估的结果——“被拘留”或“未被拘留”。
在4423例依据《精神健康法》进行的评估中，2841例（66%）导致被拘留。精神病诊断、存在风险、女性性别、社会支持水平以及评估地点为伦敦预测了依据《精神健康法》被拘留的情况。种族并非被拘留的独立预测因素。
没有证据表明在依据《精神健康法》接受评估的人群中，种族对被拘留的几率有独立影响。
