CONTEXT
The coping with death competence is of great importance for palliative care professionals, who face daily exposure to death. It can keep them from suffering compassion fatigue and burnout, thus enhancing the quality of the care provided. Despite its relevance, there are only two measures of professionals' ability to cope with death. Specifically, the Coping with Death Scale (CDS) has repeatedly shown psychometric problems with some of its items.
OBJECTIVE
The aim of this study was to develop and validate a short version of the CDS.
METHODS
Nine items from the original CDS were chosen for the short version. Two cross-sectional surveys were conducted in Spanish (N = 385) and Argentinian (N = 273) palliative care professionals. The CDS and the Professional Quality of Life Scale were used in this study. Statistical analyses included two confirmatory factor analyses (CFAs), followed by a standard measurement invariance routine. Reliability estimates and evidence of validity based on relations with other measures were also gathered.
RESULTS
CFA models had excellent fit in both the Spanish (χ(27) = 107.043, P < 0.001; Comparative Fit Index [CFI] = 0.978; Tucker-Lewis Index [TLI] = 0.970; Root Mean Square Error of Approximation [RMSEA] = 0.093 [0.075, 0.112]; Standardized Root Mean Square Residual = 0.030) and Argentinian (χ(27) = 102.982, P < 0.001; CFI = 0.963; TLI = 0.950; RMSEA = 0.106 [0.085, 0.128]) samples. A standard measurement invariance routine was carried out. The most parsimonious model (χ(117) = 191.738, P < 0.001; CFI = 0.987; TLI = 0.992; RMSEA = 0.046 [0.034, 0.058]; Standardized Root Mean Square Residual = 0.043) offered evidence of invariance across countries, with no latent mean differences. Evidence of reliability and evidence of validity based on relations with other measures were also appropriate.
CONCLUSION
Results indicated the psychometric boundaries of the short version of the CDS.
背景
应对死亡的能力对于姑息治疗专业人员来说非常重要，因为他们每天都要面对死亡。这可以防止他们遭受同情疲劳和倦怠，从而提高提供的护理质量。尽管它很重要，但只有两种衡量专业人员应对死亡能力的方法。具体来说，应对死亡量表（CDS）的一些项目在心理测量学上存在问题。
目的
本研究旨在开发和验证 CDS 的简短版本。
方法
从原始 CDS 中选择了 9 个项目作为简短版本。在西班牙（N=385）和阿根廷（N=273）的姑息治疗专业人员中进行了两项横断面调查。该研究使用了 CDS 和专业生活质量量表。统计分析包括两个验证性因素分析（CFA），然后是标准的测量不变性程序。还收集了可靠性估计和基于与其他措施关系的有效性证据。
结果
在西班牙（χ²(27)=107.043，P<0.001；比较拟合指数[CFI]=0.978；Tucker-Lewis 指数[TLI]=0.970；近似均方根误差[RMSEA]=0.093[0.075，0.112]；标准化均方根残差=0.030）和阿根廷（χ²(27)=102.982，P<0.001；CFI=0.963；TLI=0.950；RMSEA=0.106[0.085，0.128]）样本中，CFA 模型的拟合度都非常好。进行了标准的测量不变性程序。最简约模型（χ²(117)=191.738，P<0.001；CFI=0.987；TLI=0.992；RMSEA=0.046[0.034，0.058]；标准化均方根残差=0.043）提供了跨国家不变性的证据，没有潜在的均值差异。可靠性和基于与其他措施关系的有效性的证据也是适当的。
结论
结果表明，CDS 简短版本的心理测量边界。
