Quality of life (QoL) is traditionally assessed using multiple-item questionnaires. These can be either general, global assessments of QoL or disease-specific questionnaires. However, the use of single-item QoL scales is becoming increasingly popular, as these are more time- and cost-effective, with a readily available and easy-to-interpret outcome. In particular, these are often preferred for quick assessments (e.g., 'at home' testing and mobile phone assessments), and other cases when time constraints are common (e.g., clinical trials and clinical practice). Previous research revealed that multiple-item questionnaires and single-item assessments of QoL have the same validity and reliability. Here we further evaluate the relationship of QoL, assessed with a single-item QoL scale, with well-being, mood, health correlates (e.g., immune fitness, and having underlying diseases), and lifestyle (e.g., sleep, nutrition). Data from two online surveys are presented. In Study 1, 100 students participated. The single-item QoL score was compared with the World Health Organization Well-Being Index (WHO-5), a single-item score of sleep quality, the Regensburg Insomnia Scale (RIS) score, and the Healthy Diet Scale (HDS). Study 2 comprised a survey among 1415 Dutch adults. Single-item QoL was evaluated and compared with assessments of mood, health correlates (immune fitness and disease status), and lifestyle factors (e.g., sleep, nutrition, stress). The first study revealed significant correlations between QoL and well-being, sleep quality, insomnia ratings, and attaining a healthy diet. The second study revealed significant correlations between QoL and mood, health status, and lifestyle factors (e.g., the ability to cope with stress). The results presented here demonstrate that the single-item QoL scale is an effective and easy-to-implement assessment tool that can be used in both clinical practice and research.
生活质量（QoL）传统上是通过多项问卷进行评估的。这些问卷可以是对生活质量的一般性、整体性评估，也可以是针对特定疾病的问卷。然而，单项生活质量量表的使用越来越普遍，因为它们更节省时间和成本，而且结果易于获取和解释。特别是，在快速评估（例如“在家”测试和手机评估）以及其他时间限制常见的情况下（例如临床试验和临床实践），这些量表通常更受青睐。先前的研究表明，多项问卷和单项生活质量评估具有相同的效度和信度。在此，我们进一步评估用单项生活质量量表评估的生活质量与幸福感、情绪、健康相关因素（例如免疫健康和患有基础疾病）以及生活方式（例如睡眠、营养）之间的关系。本文呈现了两项在线调查的数据。在研究1中，100名学生参与其中。将单项生活质量得分与世界卫生组织幸福感指数（WHO-5）、睡眠质量单项得分、雷根斯堡失眠量表（RIS）得分以及健康饮食量表（HDS）进行比较。研究2包括对1415名荷兰成年人的调查。对单项生活质量进行评估，并与情绪、健康相关因素（免疫健康和疾病状况）以及生活方式因素（例如睡眠、营养、压力）的评估进行比较。第一项研究揭示了生活质量与幸福感、睡眠质量、失眠评分以及实现健康饮食之间存在显著相关性。第二项研究揭示了生活质量与情绪、健康状况以及生活方式因素（例如应对压力的能力）之间存在显著相关性。此处呈现的结果表明，单项生活质量量表是一种有效且易于实施的评估工具，可用于临床实践和研究。
