to analyze the factor structure of the Appraisal of Self-Care Agency Scale-Revised (ASAS-R), adapted for Brazil.
methodological study conducted with 150 individuals with diabetes mellitus cared for by the Family Health Strategy, most of whom are elderly with low educational levels. The test of the hypothesis concerning the confirmatory factor composition of the ASAS-R was performed using latent variables structural equations.
the model's goodness-of-fit indexes were satisfactory (χ2 = 259.19; χ2/g.l = 2.97, p < 0.001; GFI = 0.85; RMR = 0.07; RMSEA = 0.09); the factor loads were greater than 0.40; and most item-to-factor-correlations presented moderate to strong magnitude (0.34 to 0.58); total alpha value was 0.74, while the alpha of the three factors were 0.69, 0.38 and 0.69, respectively.
the scale's factor structure presented satisfactory validity and reliability results, with the exception of one factor. Application of this scale to samples of the general population is desirable in order to strengthen analyses of internal consistency and the dimensionality of the factor structure. This study is expected to contribute to further studies addressing the self-care agency construct and the development of the ASAS-R.
分析适用于巴西的修订版自我护理能力评估量表（ASAS-R）的因子结构。
对150名由家庭健康战略提供护理的糖尿病患者进行方法学研究，其中大多数为低教育水平的老年人。使用潜在变量结构方程对ASAS-R的验证性因子构成假设进行检验。
模型的拟合优度指标令人满意（χ2 = 259.19；χ2/自由度 = 2.97，p < 0.001；GFI = 0.85；RMR = 0.07；RMSEA = 0.09）；因子载荷大于0.40；大多数项目与因子的相关性呈现中度至强度（0.34至0.58）；总α值为0.74，而三个因子的α值分别为0.69、0.38和0.69。
该量表的因子结构呈现出令人满意的效度和信度结果，但有一个因子除外。为加强内部一致性分析和因子结构的维度分析，希望将此量表应用于一般人群样本。本研究有望为进一步探讨自我护理能力结构和ASAS-R发展的研究做出贡献。
