Although the Caregiver Burden Inventory (CBI) is the most widely used multidimensional burden instrument for assessing perceived burden of caregivers, there is no data on its psychometric properties in Spanish, nor on caregivers of dependent persons with various diseases. The objective of this study was to translate the CBI into Spanish and validate it in caregivers of dependent persons with various diseases. Trained evaluators administered the CBI and assessed emotional distress and probable mental disorder in 201 caregivers (87.1% women, mean age 56.2 years). The internal consistency of the CBI was 0.89 (0.74⁻0.83 among the subscales). There was a significant correlation of emotional distress with both the total burden and each subscale ( < 0.001 in all cases). A total score of 39 and scores of 16, 9, 8, 4, and 2 in burden per time dedicated to care, personal life burden, physical burden, social burden, and emotional burden were suitable cut-off points to discriminate caregivers with probable mental disorder (sensitivity = 63.0%⁻75.6%, specificity = 63.4%⁻74.4%). To achieve a greater goodness of fit, the model was re-specified, resulting in a shortened (15-item) instrument. The internal consistency reliability coefficients of the 15-item CBI were satisfactory (Cronbach = 0.83; 0.77⁻0.86 among the subscales). Within the 15-item CBI, emotional distress was significantly correlated with the total burden, personal life burden, physical burden, social burden ( < 0.001 in all those cases), and emotional burden ( = 0.001). A total score of 25 and scores of 12, 5, 5, 3, and 1, respectively, in the subscales were identified as cut-off points to discriminate caregivers with probable mental disorder (sensitivity = 46.2%⁻70.6%, specificity = 43.9%⁻79.3%). Therefore, the 15-item CBI validly measured caregiver burden with better fit and more parsimoniously than the original CBI.
虽然照顾者负担量表（CBI）是评估照顾者感知负担最广泛使用的多维负担工具，但在西班牙语中没有关于其心理测量特性的数据，也没有关于患有各种疾病的依赖者的照顾者的数据。本研究的目的是将 CBI 翻译成西班牙语，并在患有各种疾病的依赖者的照顾者中验证其有效性。经过培训的评估员对 201 名照顾者（87.1%为女性，平均年龄 56.2 岁）进行了 CBI 评估，并评估了他们的情绪困扰和可能的精神障碍。CBI 的内部一致性为 0.89（子量表的 0.74⁻0.83）。情绪困扰与总负担和每个子量表均呈显著相关（所有情况下均<0.001）。总分为 39 分，照顾时间负担、个人生活负担、身体负担、社会负担和情绪负担分别为 16、9、8、4 和 2 分，是区分可能患有精神障碍的照顾者的合适截断值（敏感性=63.0%⁻75.6%，特异性=63.4%⁻74.4%）。为了达到更好的拟合度，对模型进行了重新指定，得到了一个缩短的（15 项）工具。15 项 CBI 的内部一致性可靠性系数令人满意（Cronbach = 0.83；子量表的 0.77⁻0.86）。在 15 项 CBI 中，情绪困扰与总负担、个人生活负担、身体负担、社会负担（所有情况下均<0.001）和情绪负担显著相关（=0.001）。各子量表的总分分别为 25 分，分数分别为 12、5、5、3 和 1，是区分可能患有精神障碍的照顾者的截断值（敏感性=46.2%⁻70.6%，特异性=43.9%⁻79.3%）。因此，15 项 CBI 比原始 CBI 更有效地衡量照顾者负担，具有更好的拟合度和更简洁性。
