This study will examine the relationship between customer engagement, value co-creation and value co-destruction within online brand communities (OBCs). The purpose of this study is twofold: 1. to examine the direct effects of customer engagement within OBCs on value co-creation and co-destruction; 2. to explore the mediating effects of brand resonance and attitudinal brand loyalty and the moderating effect of brand satisfaction on customer engagement within OBCs. An online survey will be used to collect data. PLS-SEM will be applied to examine the utility of the proposed model. Expected results are that there will be a positive relationship between customer engagement within OBCs and brand resonance, attitudinal brand loyalty and value co-creation, while a negative relationship between value co-destruction and customer engagement within OBCs is expected. Brand resonance and attitudinal brand loyalty are expected to have a positive relationship with value co-creation and a negative relationship with value co-destruction, respectively. Both brand resonance and attitudinal brand loyalty are expected to mediating roles, with brand satisfaction performing a moderating role. This study is expected to add to the existing literature on customer engagement in OBCs, and drive marketers to attach more importance on the value co-creation and co-destruction within OBCs.
