Measurement and Correlates of Food Selection Motivations in a United States Sample.

Background: In this study, we explored the factors that motivate food choice, and evaluated the psychometric properties and demographic correlates of the Eating Motivation (EATMOT) questionnaire in adults in the United States (US). Methods: This cross-sectional survey involved 905 adults in 6 sites across the US. The EATMOT questionnaire measures participants' self-reported motivations for food selection, demographic, and anthropometric data. Analyses included exploratory and confirmatory factor analyses, correlations, Welch's t-tests, and logistic regressions. Results: We established a 3-factor model (health-related, emotional, and environmental/political motivations) as the best fit to the data (CFI = .983, RMSEA = .049, SRMR = .054). Gender differences were found within the 3 factors, as well as in the intercorrelations between factors. Higher levels of health-related motivations (B = .10, SE = .04, OR = 1.11 (95% CI: 1.03, 1.19), p = .006) were associated with increased reports of weight loss dieting, whereas higher levels of environmental/political motivations (B = -.09, SE = .04, OR = 0.91, p = .02) were associated with fewer reports of weight-loss dieting. Conclusion: An abbreviated version of the EATMOT scale is appropriate for use in a US sample and identifies 3 categories of factors that impact dietary choices. These factors may be important in building interventions to improve diets.

Determinants of economic motivations for food choice: insights for the understanding of consumer behaviour.

Food consumption involves several dimensions, being some of them directly associated with the consumers' characteristics. The interrelationships between these domains impact consumer behaviour for food choice and the consequent decisions for food consumption. In these frameworks, economic motivations are determinant. On the other hand, the scientific literature highlights that the economic-based stimuli to choose food is still underexplored. In this perspective, the objective of this study was to assess the main sociodemographic and anthropometric determinants of the economic motivations for food choice. For that, a questionnaire survey was carried out involving 11,919 respondents from 16 countries. A validated questionnaire was used, translated into the native languages in all participating countries, using a back-translation process. First, the information obtained was assessed through factor analysis to reduce the number of variables associated with the economic motivations and to identify indexes. After, and considering the indexes obtained as dependent variables, a classification and regression tree analysis was performed. As main insights, it is highlighted that the main determinants of the economic motivations are country of residence, age, gender, civil state, professional activity, educational level, living environment, responsibility for buying food, weight, height, body mass index, healthy diets and physical exercise practices. Additionally, the results also reveal that economic motivations may be associated with two indexes, one related to convenience attitudes and the other to quality concerns. Finally, the younger persons and the women are the social groups more concerned with healthy diets and food quality. In conclusion, this work confirmed that food choice is to a high extent influenced by several sociodemographic and behavioural factors.
