The Five-item World Health Organization Well-being Index (WHO-5) is an increasingly used measure of generic well-being, but there is no evidence to support whether outpatients consider the questionnaire valuable. As the WHO-5 has not yet been psychometrically evaluated in specialised community mental health settings, an evaluation of its validity seems warranted. The aim of this cross-sectional study was to examine the psychometric properties of the WHO-5 in this type of setting. Data was collected from an outpatient center (N = 191 adults). Results indicate that the questionnaire was feasible to administer (n = 57 patients), it reported low mean Burden-scores and high Positive-Value scores, and had excellent internal consistency. No evidence of floor or ceiling effects was found. Results supported the unidimensional structure of the questionnaire. Significant differences were found concerning patients' diagnoses, with patients with schizophrenia diagnoses reporting higher scores and patients with depression and personality disorders reporting lower ones. When comparing the WHO-5 total score and patients' attitudes toward medication, negative correlations were observed with psychological reactance, as well as positive aspects of psychiatric medication. The present study demonstrates that the WHO-5 is feasible to administer and has robust psychometric properties in specialised community mental health centres.
五因素世界卫生组织幸福感指数（WHO-5）是一种越来越常用的通用幸福感衡量标准，但没有证据表明门诊患者认为该问卷有价值。由于 WHO-5 尚未在专门的社区心理健康环境中进行心理测量评估，因此似乎有必要对其有效性进行评估。本横断面研究旨在检验该问卷在这种环境下的心理测量特性。数据来自一个门诊中心（N=191 名成年人）。结果表明，该问卷易于管理（n=57 名患者），报告的负担评分低，积极价值评分高，并且具有极好的内部一致性。未发现地板或天花板效应的证据。结果支持问卷的单维结构。患者的诊断存在显著差异，精神分裂症诊断患者的评分较高，而抑郁症和人格障碍患者的评分较低。当比较 WHO-5 总分和患者对药物的态度时，心理阻抗以及精神病药物的积极方面与 WHO-5 总分呈负相关。本研究表明，在专门的社区心理健康中心，WHO-5 易于管理，并且具有可靠的心理测量特性。
