背景。使用标准统计检验方法，在确定的非患者人群中比较 SF-36 (MHI-5) 的 5 项心理健康维度的表现与 12 项一般健康问卷 (GHQ-12) 的表现。对 3000 名 16-64 岁患者进行了邮寄调查。患者是从代表具有不同社会经济特征的人群的两个全科诊所的诊所列表中随机选择的。结果。大量证据证明这两种工具的内部一致性（GHQ-12 和 MHI-5 的 Cronbach α 值分别为 0.91 和 0.84），以及它们在区分具有测量健康差异的群体方面的构建有效性。两种仪器显示男性和女性的平均分数存在显着差异。与 GHQ-12 相比，MHI-5 的年龄和分数之间没有发现相关性。两项文书对社会经济特征和社会支持水平同样敏感。两种仪器的得分高度相关（斯皮尔曼等级相关 -0.73）。结论。 MHI-5 具有与 GHQ-12 相当的心理测量性能，可用于测量和比较特定人群的心理健康状况。 MHI-5 相对于 GHQ-12 的操作优势在于，它属于公共领域，是一般健康措施 (SF-36) 的一部分，而且时间更短。
Background. A comparison of the performance of the 5-item mental health dimension of SF-36 (MHI-5) with that of the 12-item General Health Questionnaire (GHQ-12) in a defined, non-patient population, using standard statistical tests.Methods. A postal survey of 3000 patients aged 16-64 years was conducted. Patients were randomly selected from the practice lists of two general practices chosen to represent populations with different socio-economic characteristics.Results. Considerable evidence was found for the internal consistency of both instruments (Cronbach's alpha 0.91 and 0.84 for GHQ-12 and the MHI-5 respectively) and for their construct validity in terms of distinguishing between groups with measured health differences. Both instruments showed a significant difference in the mean scores for men and women. In contrast to the GHQ-12, no correlation was found between age and score for the MHI-5. Both instruments were equally sensitive to socio-economic characteristics and to levels of social support. The scores on the two instruments were highly correlated (Spearman rank correlation -0.73).Conclusion. The MHI-5 has comparable psychometric performance to the GHQ-12, and can be used to measure and compare mental health in defined populations. Operational advantages of the MHI-5 over the GHQ-12 are that it is in the public domain, is part of a general health measure (SF-36) and is shorter.
