Previous research on ethnocentrism and lifestyle has focused on attitudinal segmentation. However, consumer attitudes may not always be consistent with the actual purchasing decision. Since behavioural intentions are more proximal predictors of behaviours than attitudes, segmenting markets using purchasing intentions might be more appropriate. The purpose of this study is to use purchasing intention to examine whether lifestyle and ethnocentrism can be useful indicators in segmenting foreign and domestic food markets. Data were collected from 1856 households in Turkey. Ethnocentrism, lifestyle (with its dimensions of fashion consciousness, cost consciousness, health consciousness, and craftsmanship) and demographics proved to be valid instruments in segmenting domestic and foreign food markets. The findings have implications both for foreign marketers who operate in or plan to enter the emerging Turkish food industry, and for domestic operators.
