Doctor of Philosophy / Department of Hospitality Management and Dietetics / Chihyung Ok / This study attempted to investigate antecedents and consequences of consumers’ utilitarian and hedonic attitudes toward restaurant brands and to examine the effects of brand prestige on brand preference and word-of-mouth intention with customer involvement as a moderator. In study 1, to investigate the antecedents and consequences of consumer attitudes toward restaurant brands in the full-service restaurant, this study proposed, based on existing theoretical premises, significant interrelationships among three service qualities (i.e., physical environment quality, interactional quality, and outcome quality). This study also hypothesized that these service qualities predict consumers’ utilitarian and hedonic attitudes toward restaurant brands. Finally, this study examined the effects of consumer attitudes toward restaurant brands in forming brand preference and relative customer share of visits. A theoretical model was proposed and then tested with data collected from 318 casual and 303 fine dining restaurant patrons. The results of data analysis indicated significant interrelationships among three service qualities in both casual and fine dining restaurants. In addition, interactional and outcome qualities had significant effects on utilitarian and hedonic attitudes toward restaurant brands in the casual dining restaurant. In the fine dining segment, interactional quality significantly influenced both utilitarian and hedonic attitudes toward restaurant brands, while physical environment and outcome qualities had positive impacts only on hedonic attitude toward the restaurant’s brand. Finally, utilitarian and hedonic attitudes toward restaurant brands enhanced brand preference, and in turn, brand preference increased relative customer share of visits in both casual and fine dining restaurants. The purpose of study 2 was to examine the effects of brand prestige on brand preference and word-of-mouth with customer involvement as a moderator in the fine dining restaurant segment. Based on a thorough literature review, this study hypothesized that brand prestige would have positive effects on brand preference and word-of-mouth and that brand preference would have a positive relationship with word-of-mouth. Finally, this study examined the moderating role of customer involvement in the relationships between (1) brand prestige and brand preference, (2) brand prestige and word-of-mouth, and (3) brand preference and word-of-mouth. A total of 293 questionnaire responses were used to empirically test the proposed relationships in fine dining restaurants. This study found that brand prestige has significant effects on brand preference and word-of-mouth. In addition, brand preference had a positive relationship with word-of-mouth. However, customer involvement as a moderator was not supported.

Doctor of Philosophy / Department of Hospitality Management and Dietetics / Chihyung Ok, Deborah D. Canter / This study sought to apply the concepts of ‘perceived value’ and ‘customer share’ (of visits) to full-service restaurant settings for the first time. Given the strong ‘experiential nature’ of foodservice, the perceived value concept adopted in this study involved an ‘experiential view’ of the dining experience. Further, the customer share concept was expected to have implications for the foodservice context, given the multi-loyalty nature of restaurant customers. With the first conceptual model, this study sought to verify the effect of perceived value on customer share of visits in a full-service restaurant context, using a dimension-level value approach and positing customer satisfaction and brand preference as mediators between them. The conceptual model was tested based on responses from 299 general U.S. full-service restaurant customers, using a confirmatory factor analysis and structural equation modeling. The test results revealed that among four value dimensions, excellence (in food and service) and customer return on investment had dominant effects on customer satisfaction and brand preference whereas playfulness had a significant moderate effect only on brand preference; aesthetic appeals did not have significant effects on either. Affected by perceived value, customer satisfaction significantly enhanced brand preference and in turn brand preference contributed to customer share of visits and fully mediated the effect of customer satisfaction on customer share of visits. In essence, the findings highlight the significant antecedent role of perceived value in customers’ satisfaction and brand preference formation, and the pivotal role of customer brand preference in customers’ purchase decision process. With the second conceptual model, this study sought to reveal the direct effect and/or moderating effects of contingency variables in relation to customer share of visits in a fullservice restaurant context. The hypotheses included in the conceptual model were tested based on responses from 291 general U.S. full-service restaurant customers, using a confirmatory factor analysis and a series of (moderated hierarchical) regression analyses. The test results indicated that the direct effects of social switching costs, lost benefits costs, procedural costs, and intrinsic inertia were positive whereas that of intrinsic variety-seeking was negative on customer share of visits. In addition, consumer involvement and perceived brand heterogeneity were found to enhance the effect of brand preference on customer share of visits. The effects of the contingency variables appear to work by influencing the number of brands in customers’ consideration sets and/or leading customers to allocate a greater share of visits to a particular brand in a given number of brands in consideration sets.
