OBJECTIVE
To analyze the validity based on the internal structure and reliability of the Brazilian version of the Caregiver Reaction Assessment (CRA) applied to informal caregivers of dependent elderly.
METHOD
A methodological study with 120 informal caregivers of the elderly. Validity based on the internal structure evaluated by exploratory factorial analysis, with extraction of main factorial axes, varimax orthogonal rotation and retention of factors by parallel analysis. Reliability assessed by Cronbach's alpha.
RESULTS
The instrument revealed a factorial structure different from the original version: three factors were identified, equivalent to subscales, self-esteem, daily activities and family support, with explained variance of 42%. The values of the Cronbach alpha for the items belonging to each subscale were, respectively: 0.71, 0.81 and 0.83.
CONCLUSION
The Brazilian version of CRA presents good evidence of validity based on internal structure and is reliable, and can be used to assess the overload of informal caregivers of dependent elderly.
目的
基于应用于依赖他人生活的老年人的非正式照料者的巴西版照料者反应评估（CRA）的内部结构和信度，分析其效度。
方法
对120名老年人的非正式照料者进行一项方法学研究。基于通过探索性因子分析评估的内部结构的效度，提取主要因子轴，进行方差最大化正交旋转，并通过平行分析保留因子。通过克朗巴赫α系数评估信度。
结果
该工具显示出与原始版本不同的因子结构：识别出三个因子，等同于分量表，即自尊、日常活动和家庭支持，解释方差为42%。属于每个分量表的项目的克朗巴赫α系数值分别为：0.71、0.81和0.83。
结论
巴西版CRA基于内部结构呈现出良好的效度证据且具有信度，可用于评估依赖他人生活的老年人的非正式照料者的负担过重情况。
