Measurement invariance in the Satisfaction with Food-related Life scale: A comparison of Chilean and Spanish university students

Community Supported Agriculture as a Driver of Food-Related Well-Being

Background: There is a growing amount of research interest to understand the role of food in well-being. The demand for community supported agriculture (CSA), bringing people spatially, economically, and socially closer to food, is continuously expanding. CSAs play an important role in both sustainable agriculture practices and influencing consumers’ food-related practices, but yet have received little attention in well-being research. Methods: This study explores food-related well-being among CSA members by using an exploratory, qualitative research design and a thematic analysis of semi-structured interviews. Results: The findings stress the relevance of psychological, social, and spiritual aspects of food-related well-being beyond the nutritional characteristics of food in CSA. Conclusion: The role of sustainable agriculture in contributing to food-related well-being becomes particularly evident based on consumers’ experiences. These results are important in convincing people that their food-related experiences belong to their perceived well-being as well as stimulating people to elevate their multidimensional expectations in relation to food.

Cross-cultural measurement invariance in the satisfaction with food-related life scale in older adults from two developing countries

BACKGROUND

Nutrition is one of the major determinants of successful aging. The Satisfaction with Food-related Life (SWFL) scale measures a person's overall assessment regarding their food and eating habits. The SWFL scale has been used in older adult samples across different countries in Europe, Asia and America, however, there are no studies that have evaluated the cross-cultural measurement invariance of the scale in older adult samples. Therefore, we evaluated the measurement invariance of the SWFL scale across older adults from Chile and Ecuador.

METHODS

Stratified random sampling was used to recruit a sample of older adults of both genders from Chile (mean age = 71.38, SD = 6.48, range = 60-92) and from Ecuador (mean age = 73.70, SD = 7.45, range = 60-101). Participants reported their levels of satisfaction with food-related life by completing the SWFL scale, which consists of five items grouped into a single dimension. Confirmatory factor analysis (CFA) was used to examine cross-cultural measurement invariance of the SWFL scale.

RESULTS

Results showed that the SWFL scale exhibited partial measurement invariance, with invariance of all factor loadings, invariance in all but one item's threshold (item 1) and invariance in all items' uniqueness (residuals), which leads us to conclude that there is a reasonable level of partial measurement invariance for the CFA model of the SWFL scale, when comparing the Chilean and Ecuadorian older adult samples. The lack of invariance in item 1 confirms previous studies with adults and emerging adults in Chile that suggest this item is culture-sensitive. We recommend revising the wording of the first item of the SWFL in order to relate the statement with the person's life.

CONCLUSIONS

The SWFL scale shows partial measurement invariance across older adults from Chile and Ecuador. A 4-item version of the scale (excluding item 1) provides the basis for international comparisons of satisfaction with food-related life in older adults from developing countries in South America.
