Using data from a community survey of 5196 ethnic minority and 2867 white respondents, together with data on local group concentration from the 1991 Census, the hypothesis was tested that ethnic group concentration is associated with lower levels of reported psychiatric symptoms. The hypothesis was broadly confirmed, both for within- and between-group differences. However, the effect was found to be modest in size and in one group, the Pakistani sample, was reversed. The findings are inconsistent with an explanation based on selection or drift. Linguistic factors contributed to, but did not explain the effects. Evidence on victimisation and mutual support suggests that social causation, in the form of reduced exposure to direct prejudice and increased social support, is a likely cause of the effect.
利用对5196名少数族裔受访者和2867名白人受访者进行的社区调查数据，以及1991年人口普查中关于当地群体聚居情况的数据，对族裔群体聚居与所报告的精神症状水平较低相关这一假设进行了检验。该假设在组内和组间差异方面都得到了广泛证实。然而，发现该效应规模不大，在一个群体即巴基斯坦样本中，该效应则相反。研究结果与基于选择或漂移的解释不一致。语言因素有一定作用，但无法解释这些效应。关于受害和相互支持的证据表明，以较少接触直接偏见和更多社会支持形式存在的社会因果关系可能是造成这种效应的原因。
