Psychometric properties of the satisfaction with food-related life scale: application in southern Chile

Abstract

Objective: 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.

Methods: A survey was applied to a sample of 316 persons in the principal cities of southern Chile distributed with proportional attachment per city.

Results: 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.

Conclusions and implications: 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.

Keywords: Satisfaction with Food-related Life; factor analysis; food, well-being.
