PolyU Tourism Service Quality Index Models
The model for service quality index builds upon the Brady-Cronin model which, in turn, is an integration of the Nordic model and the SERVQUAL model (Brady & Cronin, 2001; Grönroos, 1984). Considering the virtue of parsimony and ease of use, we develop the model for service quality index by modifying the Brady-Cronin model on two aspects (Figure 37). First, we drop the nine sub-dimensions at the second hierarchical level, for we believe that one sub-dimension for each quality facet can also capture the very quality aspect. This modification leads to an appreciated simplification model for service quality index, too. Specifically, interaction quality is measured by the sub-dimension of behavior on the two quality dimensions. Physical environment quality is measured by the sub-dimension of ambient conditions, and outcome quality is measured by tangibles as the only sub-dimension. Second, we replace physical environment quality with servicescape quality without changing its indicators.
