This study aimed to examine the psychometric properties of the original 14-item version of the Warwick-Edinburgh Mental Well-Being Scale (WEMWBS) and the short 7-item version (SWEMWBS) to validate these scales for use among Norwegian adolescents.
Cross-sectional data were collected by distributing questionnaires among students in five upper secondary schools in Norway with a net sample of n = 1814. Exploratory- and confirmatory factor analyses (CFA) and a reliability analysis were conducted and possible floor and ceiling effects were examined to evaluate the scales. A correlation analysis was conducted to examine criterion-related validity.
The preliminary exploratory factor analysis gave strong indications of a one-dimensional solution for both versions of the scale. Furthermore, both scales showed high internal consistency (Cronbach's α = .93 for the WEMWBS and α = .88 for the SWEMWBS). The SWEMWBS showed the best fit in the CFA and a strong correlation with the WEMWBS ( r = .94). The score distributions of both scales indicated the possibility of a small ceiling effect. Both scales showed high correlations with related constructs in the expected direction.
In our study, based on the CFA results and the high correlation between the original scale and the short version, the SWEMWBS was found to be most suitable for use among Norwegian adolescents.
本研究旨在检验原始的 14 项沃里克-爱丁堡心理健康量表（WEMWBS）和 7 项简短版本（SWEMWBS）的心理测量特性，以验证这些量表在挪威青少年中的适用性。
通过向挪威五所高中的学生发放问卷，收集横断面数据，有效样本量为 1814 名。进行了探索性和验证性因素分析（CFA）以及可靠性分析，并检查了可能的地板效应和天花板效应，以评估这些量表。进行了相关分析以检验效标关联效度。
初步探索性因素分析强烈表明两个版本的量表均具有一维解决方案。此外，两个量表均表现出较高的内部一致性（WEMWBS 的 Cronbach's α =.93，SWEMWBS 的 α =.88）。SWEMWBS 在 CFA 中表现出最佳拟合度，与 WEMWBS 呈强相关（r =.94）。两个量表的分数分布表明可能存在小的天花板效应。两个量表均与预期方向的相关结构高度相关。
在我们的研究中，根据 CFA 结果以及原始量表与简短版本之间的高度相关性，发现 SWEMWBS 最适合在挪威青少年中使用。
