외식기업 촉진 메시지 전략에 관한 연구: 기대-불일치모형과 동화-대조이론을 중심으로 = A Study on Promotional Message Strategy in Food service company: Based on Expectancy-disconfirmation model and Assimilation-contrast theory

다국어 초록 (Multilingual Abstract)

The purpose of this study is to present a quantitative standard with regards to the borderline between latitudes of acceptance and latitudes of rejection where assimilation-contrast effects appear, so that reasonable criteria for range of acceptance of customers whose behavioral decisions are influenced by exaggerated promotional messages from foodservice companies. Also, this study aims to explain the reason that assimilation, contrast, and assimilation-contrast effects appear by classifying groups based on quantitative criteria and identifying the difference between groups in terms of causal relationship among expectancy, outcome, disconfirmation, and satisfaction. In addition, this study aims to establish practically applicable and efficient promotional messages by identifying psychological mechanisms of customers that affect their satisfaction. Summary of analysis is as follows. In this study, manipulated expectancy level of 20~40% is identified as assimilation zone. In contrast, manipulated expectancy level of 60~100% is identified as contrast zone. Also, path analysis per each group after re-classifying each condition into group with low level of exaggeration and group with high level of exaggeration based on the results of difference verification showed significant positive correlation between expectancy and outcome and significant positive correlation between expectancy and satisfaction in Low group. In contrast, in High group, there was significant negative correlation between expectancy and outcome and there was no significant correlation between expectancy and satisfaction. Analysis suggests following points. First, theoretically, this research is meaningful in that it presents the zone of assimilation-contrast in a quantitative way through experimental design for the first time. Practically, this study is meaningful in that it presents the criteria for the level of exaggeration in promotional messages during promotions through picture or model of food. However, this study holds a limitation for generalization to other fields of food services because it is based on a single menu.
