A large number of operational definitions of brand loyalty have been proposed in the marketing literature. The advent of scanner panel data has added to this trend. This work reviews past measures of loyalty, empirically uncovers underlying dimensions of the construct, and tests these dimensions for reliability and validity using single-source scanner data. Fifteen measures chosen for study yield four underlying dimensions that are distinct from each other and that produce different results when incorporated into a choice model. Implications are drawn for the use of loyalty variables in scanner panel studies.
