Information on the psychometric properties of the Beck Depression Inventory II (BDI-II) in family caregivers of children with chronic diseases is currently unavailable, indicating a significant gap in the literature. Therefore, we investigated 1) which of the five evaluated measurement models had the best fit, 2) the scale's reliability, and 3) the scale's convergent validity.
In 2018, a cross-sectional ex post facto study with non-probability convenience sampling was conducted in 446 family caregivers of children with chronic diseases at the National Institute of Health in Mexico City; the family caregivers responded to the BDI-II and a battery of instruments measuring anxiety, caregiver burden, parental stress, well-being, and quality of life. A confirmatory factor analysis was conducted to determine the fit of the five models. Cronbach's alpha and composite reliability were calculated to assess the scale's reliability, and Spearman´s rank correlation was used to investigate the scale's convergent validity.
This study provided evidence that the two-factor somatic-affective and cognitive model had the best fit. The BDI-II demonstrated adequate reliability and evidence of convergent validity, as the BDI-II factors were positively correlated with anxiety, caregiver burden, and parental stress and negatively correlated with well-being and quality of life.
The findings reveal that the BDI-II is a valid, reliable, and culturally relevant instrument to measure depression in family caregivers of children with chronic diseases.
目前尚缺乏儿童慢性病患者家庭照顾者贝克抑郁量表第二版（BDI-II）心理计量学特性的信息，这表明文献中存在重大空白。因此，我们调查了 1）评估的五个测量模型中哪个具有最佳拟合度，2）该量表的信度，以及 3）该量表的聚合效度。
2018 年，在墨西哥城国家卫生研究院，采用非概率便利抽样的横断前瞻性研究对 446 名儿童慢性病患者的家庭照顾者进行了调查；家庭照顾者回答了 BDI-II 以及一套评估焦虑、照顾者负担、父母压力、幸福感和生活质量的工具。进行验证性因子分析以确定五个模型的拟合度。计算克朗巴赫的 alpha 和综合可靠性以评估量表的信度，并使用斯皮尔曼等级相关来研究量表的聚合效度。
本研究提供了证据表明，双因素躯体情感和认知模型具有最佳拟合度。BDI-II 具有足够的信度和聚合效度的证据，因为 BDI-II 因子与焦虑、照顾者负担和父母压力呈正相关，与幸福感和生活质量呈负相关。
研究结果表明，BDI-II 是一种有效的、可靠的、具有文化相关性的工具，可用于衡量儿童慢性病患者家庭照顾者的抑郁状况。
