One of the available tools for assessing caregiver grief is the Marwit-Meuser Caregiver Grief Inventory - Short Form, which has not been translated into Farsi. This study aimed to translate and psychometrically evaluate the short form of this Inventory in family caregivers of patients with dementia in Iran.
After translating the inventory, face validity was assessed using the item impact score method. Content validity was evaluated both qualitatively and quantitatively by calculating the content validity index and ratio. Item analysis was performed, and construct validity was examined using exploratory factor analysis with maximum likelihood estimation and Promax rotation, as well as confirmatory factor analysis. Internal consistency was determined by calculating Cronbach's alpha, omega coefficient, and the average inter-item correlation.
All items had an impact score greater than 1.5. The content validity ratio of all items exceeded 0.62, and all items had a kappa score higher than 0.75. In exploratory factor analysis, two items were removed due to cross-loading, and the two-factor structure with 16 items explained 48.34% of the variance. In confirmatory factor analysis, the indices indicated an acceptable model fit for the two-factor structure. Cronbach's alpha and omega for Factor 1 were both 0.9, while Cronbach's alpha for Factor 2 was 0.86 and its omega was 0.87. The average inter-item correlation was also within the acceptable range.
The findings of this study indicate that the Farsi short-form version of the Marwit-Meuser Caregiver Grief Inventory exhibits acceptable psychometric properties in a population of family caregivers of Farsi-speaking dementia patients. This tool can assist nurses, physicians, and other clinical professionals working with caregivers in assessing grief, identifying its presence, and planning necessary interventions.
评估照料者悲伤情绪的现有工具之一是《Marwit-Meuser照料者悲伤量表简版》，该量表尚未翻译成波斯语。本研究旨在对该量表简版进行翻译，并对其在伊朗痴呆症患者家庭照料者中的心理测量特性进行评估。
在对量表进行翻译后，采用项目影响得分法评估表面效度。通过计算内容效度指数和比率，从定性和定量两方面评估内容效度。进行项目分析，并使用最大似然估计和Promax旋转的探索性因素分析以及验证性因素分析来检验结构效度。通过计算Cronbach's alpha系数、omega系数和平均项目间相关性来确定内部一致性。
所有项目的影响得分均大于1.5。所有项目的内容效度比率均超过0.62，所有项目的kappa得分均高于0.75。在探索性因素分析中，由于交叉负荷，删除了两个项目，由16个项目组成的两因素结构解释了48.34%的方差。在验证性因素分析中，各项指标表明两因素结构的模型拟合度可接受。因素1的Cronbach's alpha系数和omega系数均为0.9，因素2的Cronbach's alpha系数为0.86，omega系数为0.87。平均项目间相关性也在可接受范围内。
本研究结果表明，《Marwit-Meuser照料者悲伤量表简版》的波斯语版本在说波斯语的痴呆症患者家庭照料者群体中具有可接受的心理测量特性。该工具可帮助护士、医生和其他与照料者合作的临床专业人员评估悲伤情绪、识别其存在情况并规划必要的干预措施。
