The aims of this this study was to examine the psychometric properties, including internal consistency and construct validity, of the Short Warwick-Edinburgh Mental Well-Being Scale (SWEMWBS) in a sample of Danish schoolchildren aged 10-16 years.
A total of 1155 schoolchildren (54% girls) aged 10-16 years (=12 years, =1.3) responded to an electronic questionnaire as part of the Danish SELFCARE study. To examine the internal consistency and construct validity of the SWEMWBS, we performed descriptive statistics, reliability and correlation analyses in Stata as well as confirmatory factor analysis (CFA) in Mplus. Correlations between scores on the SWEMWBS and scores on scales from the Strengths and Difficulties Questionnaire (SDQ) were calculated using Spearman's rank correlation coefficients. The analysis was conducted on the general study population and in subgroups divided by sex and class (age groups).
CFA confirmed SWEMWBS one-dimensional factor structure, and the model fit the data well (CFI=0.984, TLI=0.97, RMSEA=0.062 and SRMR=0.021). The scale showed satisfactory internal consistency (ɑ=0.78) and composite reliability (ω=0.82). In addition, the scale was shown to have acceptable construct validity. Thus, correlations between scores on the SWEMWBS and SDQ subscales were in line with expectations. Corresponding results were found for subgroups divided by sex and class (age groups).
Our study indicates that the Danish translation of the SWEMWBS is valid for measuring well-being among Danish schoolchildren aged 10-16 years. This construct validation study is among the first to validate the SWEMWBS in younger populations.
本研究旨在检验短式 Warwick-爱丁堡心理健康量表（SWEMWBS）在丹麦 10-16 岁学童样本中的心理测量学特性，包括内部一致性和构念效度。
共有 1155 名 10-16 岁（54%为女生）的学童（=12 岁，=1.3）作为丹麦 SELFCARE 研究的一部分，通过电子问卷进行了回复。为了检验 SWEMWBS 的内部一致性和构念效度，我们在 Stata 中进行了描述性统计、信度和相关性分析，以及在 Mplus 中进行了验证性因素分析（CFA）。使用 Spearman 等级相关系数计算 SWEMWBS 得分与优势与困难问卷（SDQ）量表得分之间的相关性。分析在总体研究人群以及按性别和班级（年龄组）划分的亚组中进行。
CFA 证实了 SWEMWBS 的单维结构，该模型很好地拟合了数据（CFI=0.984，TLI=0.97，RMSEA=0.062，SRMR=0.021）。该量表显示出令人满意的内部一致性（ɑ=0.78）和综合可靠性（ω=0.82）。此外，该量表具有可接受的构念效度。因此，SWEMWBS 得分与 SDQ 分量表之间的相关性与预期相符。在按性别和班级（年龄组）划分的亚组中也得到了相应的结果。
我们的研究表明，SWEMWBS 的丹麦语翻译在测量 10-16 岁丹麦学童的幸福感方面是有效的。这项构念验证研究是首次在年轻人群中验证 SWEMWBS 的研究之一。
