6. Limitations and future
research Despite the stated contributions, this study has a number of limitations that offer scope for further research. First, the study context is limited to a single (Indian) cultural and economic context; thus a cross-cultural study could be conducted that empirically examines the effect of culture on consumer engagement (Hollebeek, 2017). Second, this study is cross-sectional in nature, conducted at a particular point in time. However, given the dynamic nature of consumer engagement, the undertaking of longitudinal research is recommended to further explore the development of OBC-based consumer engagement over time (Viswanathan et al., 2017). Third, this study is limited to Facebook-based OBCs; thus little is known about the observed dynamics on other social networking sites (e.g. Twitter, etc.). For example, LinkedIn’s more utilitarian nature may reveal differing findings to those attained for the Facebook community studied. Fourth, this study can be extended in specific industry- (e.g. consumer electronics, fashion, etc.), or brand-related (e.g. service, B2B or luxury brand-based) OBC contexts, to confirm this study’s external validity. Fifth, given the need for further insight into consumer engagement’s role within the broader nomological network, future research may wish to consider incorporating different constructs into particular empirical models, including brand experience, commitment, trust, etc. (Brodie et al., 2011). Sixth, this study was conducted in a collectivist culture. Future research may thus wish to explore the conceptual model in differing cultural settings, including more individualistic cultures (Hollebeek, 2017). Finally, alternate theoretical frames (other than congruity theory) may be applied to consumer engagement in OBCs, including resource exchange theory, social practice theory and social penetration theory, which may provide unique findings that can be compared and contrasted to those attained in this study.
