BACKGROUND The link between mental illness and mental health is gaining focus in research and practice. This study aimed to investigate the association of mental disorders with positive mental health (PMH), overall health and quality of life. In addition, the role of PMH in mediating the relationships between mental disorders and health outcomes was assessed. METHODS The study sample comprised 2270 residents aged 18 years and above who participated in a nationally representative, cross-sectional survey estimating the lifetime prevalence of mood, anxiety and alcohol use disorders, and health outcomes (self-reported overall health, quality of life and PMH) in Singapore. The Positive Mental Health Instrument was used to estimate the level of Total PMH among the respondents with and without mental disorders. Associations between mental disorders and health outcomes were assessed through regression models. Path analyses were conducted to investigate mediating role of PMH. RESULTS Total PMH (Mean ± SD) was significantly lower among individuals having any of the studied lifetime mental disorders (4.23 ± 0.64 versus 4.50 ± 0.67 among those without these disorders). Although having a mood or anxiety disorder was associated with significantly lower Total PMH even after controlling for socio-demographic characteristics, similar relationship was not observed for alcohol use disorders. History of any mental disorders was also associated with lower overall health and quality of life. Total PMH mediated the relationships between mental disorders and overall health and quality of life by reducing the effect sizes for the associations between mental disorders and these health outcomes. CONCLUSIONS Mental disorders were associated with poor health outcomes in affected individuals. This study showed that PMH can mediate the relationships between mental disorders and health outcomes, and act as an underlying mechanism to improve overall health and quality of life in individuals with mental disorders. Findings thus highlight the significance of incorporating mental health promotion and interventions in clinical populations.

了解精神障碍，自我报告的健康结果和积极的心理健康之间的关系：国家调查的结果。

背景技术精神疾病与精神健康之间的联系正在研究和实践中得到关注。这项研究旨在调查精神障碍与积极的心理健康（PMH），整体健康和生活质量的关系。此外，评估了PMH在介导精神障碍与健康结果之间关系中的作用。方法该研究样本包括2270名18岁及以上的居民，他们参加了一项全国代表性的横断面调查，估计一生的情绪，焦虑和饮酒障碍以及健康状况（自我报告的总体健康状况，生活质量和PMH）在新加坡。积极心理健康工具用于估计有或没有精神障碍的受访者的总PMH水平。通过回归模型评估了精神障碍与健康结果之间的关联。进行了路径分析以调查PMH的中介作用。结果患有任何研究过的终生精神障碍的个体的总PMH（均值±SD）显着较低（4.23±0.64，而无这些精神障碍的个体为4.50±0.67）。尽管即使在控制了社会人口统计学特征后，情绪或焦虑症患者的总PMH仍显着降低，但对于饮酒障碍患者却未观察到类似的关系。任何精神障碍的病史也与总体健康状况和生活质量下降有关。总PMH通过减小精神障碍与这些健康结局之间关联的影响量来介导精神障碍与整体健康和生活质量之间的关系。结论精神障碍与受影响个体健康状况差有关。这项研究表明，PMH可以介导精神障碍与健康结果之间的关系，并且可以作为改善精神障碍患者整体健康状况和生活质量的基本机制。因此，发现突出了将精神健康促进和干预措施纳入临床人群的重要性。这项研究表明，PMH可以介导精神障碍与健康结果之间的关系，并且可以作为改善精神障碍患者整体健康状况和生活质量的基本机制。因此，发现突出了将精神健康促进和干预措施纳入临床人群的重要性。这项研究表明，PMH可以介导精神障碍与健康结果之间的关系，并且可以作为改善精神障碍患者整体健康状况和生活质量的基本机制。因此，发现突出了将精神健康促进和干预措施纳入临床人群的重要性。
