The aim of the present study was the construction and psychometric evaluation of a shortened version of the Burnout Screening Scales II (BOSS II), a measure for exhaustion and burnout.
To this end, among a representative sample of the German general population (N = 2429, 52.9% women), we shortened the scale from 30 to 15 items applying ant-colony-optimization, and calculated item statistics of the short version (BOSS II-short). To estimate its reliability, we used McDonald's Omega (ω). To demonstrate validity, we compared the correlation between the BOSS II-short and the BOSS II, as well as their associations with depression, anxiety, and quality of life. Furthermore, we evaluated model fit and measurement invariance across respondent age and gender in confirmatory factor analyses (CFA). Finally, we present adapted norm values.
The CFA showed an excellent model fit (χ = 223.037, df = 87, p < .001; CFI = .975; TLI = .970; RMSEA [90%CI] = .036 [.031;.040]) of the BOSS II-short, and good to very good reliability of the three subscales: 'physical' (ω = .76), 'cognitive' (ω = .89), and 'emotional' (ω = .88) symptoms. There was strict measurement invariance for male and female participants and partial strict invariance across age groups. Each subscale was negatively related to quality of life ('physical': r = -.62; 'cognitive': r = -.50; 'emotional': r = -.50), and positively associated with depression ('physical': r = .57; 'cognitive': r = .67; 'emotional': r = .73) and anxiety ('physical': r = .50; 'cognitive': r = .63; 'emotional': r = .71).
Overall, the BOSS II-short proved to be a valid and reliable instrument in the German general population allowing a brief assessment of different symptoms of exhaustion. Norm values can be used for early detection of exhaustion.
本研究旨在构建并进行心理测量评估《倦怠筛查量表II》（BOSS II）的简版，该量表用于衡量疲惫和倦怠程度。
为此，在德国普通人群的代表性样本（N = 2429，52.9%为女性）中，我们运用蚁群优化算法将量表从30项缩短至15项，并计算了简版（BOSS II - short）的项目统计量。为评估其信度，我们使用了麦克唐纳欧米伽系数（ω）。为证明效度，我们比较了BOSS II - short与BOSS II之间的相关性，以及它们与抑郁、焦虑和生活质量的关联。此外，我们在验证性因素分析（CFA）中评估了模型拟合度以及不同年龄和性别的被试间测量不变性。最后，我们给出了适配的常模值。
CFA显示BOSS II - short具有出色的模型拟合度（χ = 223.037，df = 87，p <.001；CFI =.975；TLI =.970；RMSEA [90%CI] =.036 [.031;.040]），三个子量表的信度良好到非常好：“身体”（ω =.76）、“认知”（ω =.89）和“情绪”（ω =.88）症状。男性和女性参与者之间存在严格的测量不变性，不同年龄组之间存在部分严格不变性。每个子量表与生活质量呈负相关（“身体”：r = -.62；“认知”：r = -.50；“情绪”：r = -.50），与抑郁呈正相关（“身体”：r =.57；“认知”：r =.67；“情绪”：r =.73），与焦虑呈正相关（“身体”：r =.50；“认知”：r =.63；“情绪”：r =.71）。
总体而言，BOSS II - short在德国普通人群中被证明是一种有效且可靠的工具，可用于对疲惫的不同症状进行简短评估。常模值可用于早期发现疲惫。
