Marketplace helping behavior such as opinion leadership, market maven, and purchase pals that benefit others has been extensively studied. A diverse but similar to other marketplace helping behaviors is the concept of consumer advocacy. Extant review of literature reveals that customer advocacy and consumer advocacy are conceptually different. The former is an organization level construct, and the latter is an individual consumer's ‘generalized tendency to share market information’. It is argued that a following dissatisfactory service encounter, consumer advocates would indulge in market placing helping behavior such as negative word of mouth to prevent other consumers' from having similar marketplace disappointments. Hence, prior studies link consumer advocacy to ‘altruistic tendencies’. On the basis of self-construal theory, this study investigates the motivations for consumer advocacy. Using a scenario-based experimentation implemented in survey method; we establish that consumer advocacy is motivated by an amalgamation of altruism and self-interest. We also operationalize third-party complaint construct and empirically test whether consumer advocacy is a predictor.
