This study examines the link between psychological empowerment, relationship quality and word of mouth in a brand Facebook page. It is intended to help brand marketers establish and apply successful relationship marketing strategies in the online environment. Successful implementation of relationship marketing in social networking sites will contribute to favorable consumer behaviors such as positive word of mouth. Based on the data collected from 10 hospitality brand Facebook pages, Partial Least Square (PLS) analysis was used to examine the structural interrelationship between psychological empowerment, relationship quality and online word of mouth. The empirical findings of this study were threefold. First, higher consumer psychological empowerment resulted in higher relationship satisfaction. Second, greater relationship satisfaction led to higher relationship commitment and relationship trust. Third, better relationship quality (relationship satisfaction, relationship commitment and relationship trust) contributed in greater positive online word of mouth.
