Servqual model with interrelated dimensions. The case of the pharmacy in mexico

This research is focused on understanding the interrelation between the different dimen-sions of the SERVQUAL model in the pharmaceutical area, which have differences in per-ceptions of service domains depending on the cultures in which they are immersed. To study the proposed relationships, we collect data of 100 pharmacy customers of Mex-ico and use SEM to test the relationship between SERVQUAL dimensions, purchase fre-quency, gender, and quality perception. Our results show that the SERVQUAL dimensions are interrelated, SERVQUAL dimen-sions and gender predict the perception of quality but not the purchase frequency. These results provide key information in order to understand in a better way the service quality inthe pharmaceutical area. We develop a theoretical framework that is based on interrelationships between the dif-ferent dimensions of SERVQUAL, assuming that they are not independent of each other. This way of understanding SERVQUAL dimensions can provide relevant information to un-derstand better how individual perceptions affect the service quality in the pharmaceutical area.
