The study reassessed the configural and metric structures of the Brazilian version of the Control, Autonomy, Self-realization and Pleasure (CASP-19) quality-of-life scale. Data came from the EpiFloripa Ageing Study, which included 1,131 respondents from Southern Brazil. The original and two recently factorial solutions for the Brazilian CASP-19 were initially examined. Exploratory Factor Analyses and Exploratory Structural Equation Models were estimated in the first half of the sample, selected at random. In the second half, Confirmatory Factor Analyses determined the most tenable configural and metric model for the instrument. Neither the original nor the two Brazilian solutions were supported by our data. Instead, we suggest that two factors underlie CASP-19's configural structure: while the first one groups the control and autonomy dimensions, the second combines self-realization and pleasure. Except for four items, all others presented moderate to strong loadings, and only two showed a theoretically meaningful and sufficiently large residual correlation, which was worthy of inclusion in the final model. Cross-loadings were not detected. When assessed in a population-based sample of older respondents, this Brazilian version of the CASP-19 appeared to have two factors, moderate to strong loadings and a pair of redundant items. Future studies should evaluate the consistency of these findings, examine the scalar structure of the instrument, and assess configural, metric and scalar invariance across social groups.

重新评估适用于巴西葡萄牙语的 CASP-19:来自基于人群的研究的见解

该研究重新评估了巴西版控制、自主、自我实现和愉悦 (CASP-19) 生活质量量表的配置和度量结构。数据来自 EpiFloripa 老化研究,其中包括来自巴西南部的 1,131 名受访者。最初检查了巴西 CASP-19 的原始解和最近两个解。探索性因素分析和探索性结构方程模型在样本的前半部分进行了估计,随机选择。在下半部分,验证性因素分析确定了该仪器最可靠的配置和度量模型。我们的数据不支持原始解决方案和两个巴西解决方案。相反,我们认为 CASP-19 的配置结构背后有两个因素:第一个将控制和自主维度组合在一起,而第二个则结合了自我实现和愉悦。除四个项目外,其他项目均呈现中等至强负荷,只有两个项目具有理论上的意义和足够大的残差相关性,值得纳入最终模型。未检测到交叉加载。当在基于人群的老年受访者样本中进行评估时,这个巴西版本的 CASP-19 似乎有两个因素,中度到强负荷和一对冗余项目。未来的研究应该评估这些发现的一致性,检查仪器的标量结构,并评估跨社会群体的配置、度量和标量不变性。所有其他人都呈现中等到强烈的载荷,只有两个表现出理论上有意义且足够大的残差相关性,值得包含在最终模型中。未检测到交叉加载。当在基于人群的老年受访者样本中进行评估时,这个巴西版本的 CASP-19 似乎有两个因素,中度到强负荷和一对冗余项目。未来的研究应该评估这些发现的一致性,检查仪器的标量结构,并评估跨社会群体的配置、度量和标量不变性。所有其他人都呈现中等到强烈的载荷,只有两个表现出理论上有意义且足够大的残差相关性,值得包含在最终模型中。未检测到交叉加载。当在基于人群的老年受访者样本中进行评估时,这个巴西版本的 CASP-19 似乎有两个因素,中度到强负荷和一对冗余项目。未来的研究应该评估这些发现的一致性,检查仪器的标量结构,并评估跨社会群体的配置、度量和标量不变性。这个巴西版的 CASP-19 似乎有两个因素,中等到强负载和一对冗余项目。未来的研究应该评估这些发现的一致性,检查仪器的标量结构,并评估跨社会群体的配置、度量和标量不变性。这个巴西版的 CASP-19 似乎有两个因素,中等到强负载和一对冗余项目。未来的研究应该评估这些发现的一致性,检查仪器的标量结构,并评估跨社会群体的配置、度量和标量不变性。
