To evaluate the psychometric properties of the Satisfaction with Food-related Life (SWFL) scale and its relation to the Satisfaction with Life Scale (SWLS) in southern Chile.
A survey was applied to a sample of 316 persons in the principal cities of southern Chile distributed with proportional attachment per city.
The results of the confirmatory factor analysis showed an adequate level of internal consistency and a good fit (root mean square error of approximation = 0.071, goodness-of-fit index = 0.95, adjusted goodness-of-fit index = 0.92) to the SWFL data (1-dimensional). The evaluation of a causal covariance structure analysis model composed of the SWFL as antecedent construct and the SWLS as consequent construct indicates a medium level of relation between the 2 constructs.
A medium level of relation between the SWFL and SWLS was found. In future studies, the SWFL may serve as a useful dependent variable in the analysis of objective indicators that may predict this variable.
评估食物相关生活满意度（SWFL）量表在智利南部的心理测量特性及其与生活满意度量表（SWLS）的关系。
对智利南部主要城市的 316 人进行了一项调查，每个城市的样本量按比例分配。
验证性因素分析的结果显示，SWFL 数据（一维）具有足够的内部一致性和良好的拟合度（均方根误差近似值=0.071，拟合优度指数=0.95，调整拟合优度指数=0.92）。由 SWFL 作为前因结构和 SWLS 作为后因结构组成的因果协方差结构分析模型的评估表明，这两个结构之间存在中等程度的关系。
发现 SWFL 和 SWLS 之间存在中等程度的关系。在未来的研究中，SWFL 可以作为分析可能预测该变量的客观指标的有用因变量。
