Measuring perceived performance of the food system and consumer food-related welfare

The paper explores the use of multi-item summated scales for the measurement of the perceived performance of the food system and of an index to measure consumer food-related welfare. Scales are developed that encompass a range of factors that influence the welfare consumers derive from food, including-food safety convenience, ethnical issues, health and nutrition, taste and rest. These scales are applied to a national sample of food consumers in the United States and the United Kingdom. On the basis of the survey results, there is evidence that the scales are both reliable and valid measures of the received performance of the food system in both countries. Art index of consumer-food-related welfare is developed that weights the various performance measures according to respondents' measure of importance. Survey respondents judge that the food system Lr not performing particularly well in either country. Although more work is required on the use of summated multi-item scales for this purpose, the results suggests that this is a potentially useful approach that provides relevant information on the impact of different elements of the food system on consumer welfare.
