the RC Model (partial-mediation: relationship components are partially mediated by brand commitment) and the BL Model (full-mediation: relationship components are fully mediated by brand love). The multiple dimensions of relationship components in the relationship foundation are not found functioning as a single factor conceptualized by the original BRQ framework. Instead, an interrelated hierarchical process characterizes how these dimensions generate impact on service brand loyalty. Besides, the six-component-one-factor solution in the framework is revised into the ten-component-three-factor solution. The result resonates with the thoughts of Park et al. (2002), Chang and Chieng (2006) and Smit et al. (2007), who treat brand relationship quality as formative instead of substantive construct; the relationship components do not correlate to constitute a second-order factor of brand relationship quality, they exercise multidimensional influences. As the SM-SBR model shows, in the context of service brand marketing the eight basic relationship components in the relationship foundation impact on brand loyalty largely through the mediation of service brand commitment and service brand love. That is, it is appropriate to regard the model structure of the original BRQ framework as useful for laying a solid foundation to foster service brand loyalty. This framework has to incorporate into the model structures of the Relationship Commitment and the Brand Love paradigms, thus establishing the SM-SBR model that brings the effects of consumer-brand relationships to full play.
