PurposeThis paper aims to examine the effect of face consciousness on purchase intention of organic food, to test whether this relationship would be moderated by purchase situation (group vs individual) and advertising appeal (altruistic vs egoistic), and to explain the mediating role of perceived social value in these moderating effects.Design/methodology/approachFour between-subjects experiments were carried out (N = 123, N = 126, N = 130, N = 123) by using online questionnaires. Measured variables were introduced to assess participants' face consciousness, perceived social value and purchase intention. Two manipulated between-subjects variable were introduced to test how purchase situation (group vs individual) and advertising appeal (altruistic vs egoistic) moderates the relationship between face consciousness and purchase intention of organic food. SPSS Statistics 24 was used for the analysis of all experimental data.FindingsConsumers with high face consciousness were more willing to buy organic food. Compared with the individual situation, face consciousness had a stronger impact on the purchase intention when the individual was in a group situation. Compared with egoistic appeals, face consciousness had a stronger impact on the purchase intention when the advertising appeal was altruistic. Perceived social value partly mediated the moderating effect of purchase situation and advertising appeal.Originality/valueThis study validates previous contributions on the effect of face consciousness on purchase intention of organic food and extends them by introducing two moderating variables. Additionally, it introduces perceived social value as a mediating variable to explain the mechanism of this effect.
