背景：国际上对心理健康的概念及其对人类生活各方面的贡献越来越感兴趣。对在人口一级监测精神健康和评估精神健康促进举措的工具的需求正在增加。本文描述了一种新的量表的开发和验证，该量表仅由与积极心理健康的不同方面有关的积极措辞项目组成：沃里克-爱丁堡心理健康量表（WEMWBS）。方法：WEMWBS是由一个专家小组根据当前的学术文献、焦点小组的定性研究和现有量表的心理测量测试制定的。它在学生和代表性人群样本上得到了验证。内容效度是通过回顾完整回答的频率和每个项目的回答分布来评估的。采用验证性因子分析来检验量表测量单一构念的假设。内部一致性采用Cronbach’s alpha评价。根据WEMWBS与其他量表之间的相关性，以及根据预先设定的假设检验该量表是否对人群有区别，来探索标准效度。使用类内相关系数评估一周后的重测信度。对偏见的敏感性是用期望反应的平衡清单来测量的。结果：WEMWBS具有良好的内容效度。验证性因子分析支持单因素假设。Cronbach's alpha分数为0.89（学生样本）和0.91（总体样本），表明量表中存在一些项目冗余。WEMWBS与其他心理健康和幸福感量表的相关性较高，与整体健康量表的相关性较低。它的分布接近正态分布，在总体样本中尺度不显示天花板效应。它以一种与其他人口调查结果基本一致的方式对人口群体进行了区分。一周重测信度高（0.83）。社会期望偏差低于或类似于其他可比量表。结论：WEMWBS是一种心理健康的衡量标准，完全关注心理健康的积极方面。作为一个短而心理测量稳健的量表，在人口样本中没有上限效应，它有望成为监测人口水平心理健康的工具。虽然WEMWBS应该吸引那些评估心理健康促进倡议的人，但重要的是，在此背景下推荐之前，要确定该量表对变化的敏感性。
Background: There is increasing international interest in the concept of mental well-being and its contribution to all aspects of human life. Demand for instruments to monitor mental well-being at a population level and evaluate mental health promotion initiatives is growing. This article describes the development and validation of a new scale, comprised only of positively worded items relating to different aspects of positive mental health: the Warwick-Edinburgh Mental Well-Being Scale (WEMWBS).Methods: WEMWBS was developed by an expert panel drawing on current academic literature, qualitative research with focus groups, and psychometric testing of an existing scale. It was validated on a student and representative population sample. Content validity was assessed by reviewing the frequency of complete responses and the distribution of responses to each item. Confirmatory factor analysis was used to test the hypothesis that the scale measured a single construct. Internal consistency was assessed using Cronbach's alpha. Criterion validity was explored in terms of correlations between WEMWBS and other scales and by testing whether the scale discriminated between population groups in line with pre-specified hypotheses. Test-retest reliability was assessed at one week using intra-class correlation coefficients. Susceptibility to bias was measured using the Balanced Inventory of Desired Responding.Results: WEMWBS showed good content validity. Confirmatory factor analysis supported the single factor hypothesis. A Cronbach's alpha score of 0.89 (student sample) and 0.91 (population sample) suggests some item redundancy in the scale. WEMWBS showed high correlations with other mental health and well-being scales and lower correlations with scales measuring overall health. Its distribution was near normal and the scale did not show ceiling effects in a population sample. It discriminated between population groups in a way that is largely consistent with the results of other population surveys. Test-retest reliability at one week was high (0.83). Social desirability bias was lower or similar to that of other comparable scales.Conclusion: WEMWBS is a measure of mental well-being focusing entirely on positive aspects of mental health. As a short and psychometrically robust scale, with no ceiling effects in a population sample, it offers promise as a tool for monitoring mental well-being at a population level. Whilst WEMWBS should appeal to those evaluating mental health promotion initiatives, it is important that the scale's sensitivity to change is established before it is recommended in this context.
