AIMS The aim of this study was to validate and report the factorial analysis of the World Health Organization's 5-item Well-being Index (WHO-5) among outpatients with type 2 diabetes. We investigated the psychometric properties of the WHO-5 and its suitability for identifying potential depressive symptoms in Polish adults with diabetes. METHODS Participants were randomly chosen among Polish diabetes outpatients and invited to participate in the cross-sectional study (N = 216). Participants completed the Polish version of the WHO-5, Problem Areas in Diabetes Scale and Patient Health Questionnaire. RESULTS Factor analyses identified the one-factor structure of the Polish version of the WHO-5. The internal consistency of the Polish version of the WHO-5 is satisfying. With regard to convergent validity, there were significant negative associations between the WHO-5 and PAID, the PHQ-9, HbA1c and the amount of medical complications. The AUC indicates that the WHO-5 is an effective measure for identifying depressive symptoms. The optimal cut off values of ≤12 yielded the best sensitivity/specificity trade-off for identifying depression among people with diabetes. CONCLUSIONS The Polish version of the WHO-5 is a reliable, valid outcome measure for outpatients with type 2 diabetes and can be a useful instrument for screening for depression in people with diabetes.

波兰版本的WHO-5作为成人糖尿病抑郁症筛查工具的验证。

目的本研究的目的是验证和报告世界卫生组织2型糖尿病门诊患者5项健康指数（WHO-5）的因子分析。我们调查了WHO-5的心理测量特性及其在波兰波兰糖尿病成年人中识别潜在抑郁症状的适用性。方法从波兰糖尿病门诊患者中随机选择参与者，并邀请他们参加横断面研究（N = 216）。参与者完成了波兰版的WHO-5，糖尿病问题量表和患者健康问卷的波兰语版本。结果因子分析确定了波兰版WHO-5的单因子结构。波兰版本的WHO-5的内部一致性令人满意。关于收敛效度，WHO-5与PAID，PHQ-9，HbA1c与医疗并发症的数量之间存在显着的负相关。AUC表明WHO-5是识别抑郁症状的有效措施。≤12的最佳截断值可在识别糖尿病患者中的抑郁症方面获得最佳的灵敏度/特异性折衷。结论波兰版的WHO-5是门诊2型糖尿病患者的可靠，有效的结局指标，并且可以作为筛查糖尿病患者抑郁症的有用工具。≤12的最佳截断值可在识别糖尿病患者中的抑郁症方面获得最佳的灵敏度/特异性折衷。结论波兰版的WHO-5是门诊2型糖尿病患者的可靠，有效的结局指标，并且可以作为筛查糖尿病患者抑郁症的有用工具。≤12的最佳截断值可在识别糖尿病患者中的抑郁症方面获得最佳的灵敏度/特异性折衷。结论波兰版的WHO-5是门诊2型糖尿病患者的可靠，有效的结局指标，并且可以作为筛查糖尿病患者抑郁症的有用工具。
