Personalization-the social content of interaction between service or r
etail employees and their customers-is advanced as an important mediat
or of customer satisfaction and patronage behavior. The influence of t
his service-enhancing factor is investigated within the nexus of SERVQ
UAL, a comprehensive measure of service quality. Survey data from 233
adult consumers show that ''personalization'' significantly influences
customer experience and evaluation of service. As hypothesized, for a
business that performs service on a physical possession, this influen
ce is subsumed in other components of SERVQUAL. In contrast, for a bus
iness delivering service in interactive encounters with customers, ''p
ersonalization'' emerges as the most important determinant of perceive
d service quality, and of customer satisfaction and other patronage in
dicators.
