It is essential to better understand the caregiving burden and its determinants to support caregivers. The aim of this study was to test the validity and reliability (internal consistency) of the caregiver burden inventory (CBI) in Iranian caregivers of elderly patients with Alzheimer.
A cross sectional study was conducted to translate and validate the CBI in Iran. The structural validity of the scale was evaluated by exploratory factor analysis. The concurrent validity was tested correlating the CBI scores with the Beck Anxiety Inventory (BAI) and the Beck Depression Inventory (BDI) scores. The internal consistency reliability was assessed using the Cronbach's alpha coefficient.
In total, we enrolled 315 caregivers of elderly patients with Alzheimer disease (79% women, mean age 56.5 ± 13.9). The structural validity of the CBI as assessed by exploratory factor analysis indicated three factors (emotional/psychological, time-dependence and physical burden) that jointly explained 45.21% of the total variance observed. The Pearson correlation coefficient for the relationship between the scores obtained on the Caregiver Burden Inventory and the BAI and the BDI were 0.69 and 0.49 respectively, confirming the concurrent validity. The Cronbach's alpha for the CBI was 0.91 ranging from 0.78 to 0.92 for its subscales.
Used in clinical practice and research, the CBI was verified to be a proper multidimensional instrument for evaluating the burden in caregivers of elderly patients with Alzheimer disease.
了解照顾者的负担及其决定因素对于支持照顾者至关重要。本研究旨在检验 caregiver burden inventory（CBI）在照顾阿尔茨海默病老年患者的伊朗照顾者中的有效性和可靠性（内部一致性）。
进行了一项横断面研究，以在伊朗翻译和验证 CBI。通过探索性因素分析评估量表的结构效度。通过将 CBI 评分与 Beck 焦虑量表（BAI）和 Beck 抑郁量表（BDI）评分相关联来测试同时效度。使用 Cronbach's alpha 系数评估内部一致性可靠性。
共有 315 名照顾阿尔茨海默病老年患者的照顾者（79%为女性，平均年龄 56.5±13.9）。通过探索性因素分析评估的 CBI 结构效度表明，三个因素（情绪/心理、时间依赖性和身体负担）共同解释了观察到的总方差的 45.21%。Caregiver Burden Inventory 得分与 BAI 和 BDI 之间的 Pearson 相关系数分别为 0.69 和 0.49，证实了同时效度。CBI 的 Cronbach's alpha 为 0.91，其分量表的范围为 0.78 至 0.92。
在临床实践和研究中使用时，CBI 被证明是评估阿尔茨海默病老年患者照顾者负担的适当多维工具。
