Psychometric Properties of the Satisfaction With Food-Related Life Scale: Application in Southern Chile

Abstract

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.
