This study presents the psychometric properties of the Brazilian version of the Appraisal of Self-Care Agency Scale - Revised (ASAS-R). The sample was made up of 627 subjects (69.8% women) aged between 18 and 88 years (mean = 38.3; SD = 13.26) from 17 Brazilian states. Exploratory factor analysis of part of the sample (n1 = 200) yielded a three-factor solution which showed adequate levels of reliability. Two confirmatory factor analyses of the other part of the sample (n2 = 427) tested both the exploratory and the original model. The analysis of convergent validity using the Subjective Happiness Scale, the Satisfaction with Life Scale, and the 36-item Short Form Health Survey Version 2 (SF-36v2) demonstrated adequate levels of validity. A significant correlation was found between levels of self-care agency and age, level of education and income. The analysis of sample members with chronic disease (n = 134) showed that higher levels of self-care agency indicated lower levels of negative impact of the chronic illness in the individual's everyday life.
本研究呈现了巴西版自我护理能力评估量表修订版（ASAS-R）的心理计量学特性。样本由来自巴西 17 个州的 627 名受试者（69.8%为女性）组成，年龄在 18 至 88 岁之间（平均值=38.3；标准差=13.26）。对部分样本（n1=200）进行的探索性因子分析得出了一个三因素解决方案，显示出了足够的可靠性水平。对另一部分样本（n2=427）的两项验证性因子分析同时检验了探索性和原始模型。使用主观幸福感量表、生活满意度量表和 36 项简短健康调查问卷第 2 版（SF-36v2）进行的收敛有效性分析表明了该量表具有足够的有效性。自我护理能力水平与年龄、教育程度和收入之间存在显著相关性。对患有慢性病的样本成员（n=134）的分析表明，自我护理能力水平越高，慢性病对个体日常生活的负面影响越低。
