A review of twenty years of SERVQUAL research

This paper reviews 20 years (1988‐2008) of research on the SERVQUAL scale for measuring service quality.

A range of studies that have applied the SERVQUAL scale in this 20‐year period are examined in a non‐exhaustive review of the literature. These studies are selected from well‐known databases – such as “ABI/Inform”, “ScienceDirect”, and “EBSCOhost”.

The paper identifies and summarizes numerous theoretical and empirical criticisms of the SERVQUAL scale. Despite these criticisms, the paper concludes that SERVQUAL remains a useful instrument for service‐quality research.

The paper provides a useful source of information on SERVQUAL and its applications. In particular, the paper summarizes a selection of 30 applications of SERVQUAL.
