This study examines for the first time, antecedents of relationship commitm
ent in service industries in an Eastern cultural context. The study investi
gates the reasons for customers engaging in long-term relational exchanges
with service firms, as well as the impact of attractive alternatives and sw
itching costs on such relationships. The sample comprised respondents in Ba
ngkok, Thailand who each completed a series of five questionnaires over a p
eriod of two weeks pertaining to their relational behaviour (technical serv
ice performance, social bonds and communication) with five predesignated se
rvice types. The results indicate that collectivist cultural norms impact t
he nature of relationships, and that antecedent variables have significantl
y different impacts across service types. Furthermore, switching costs were
identified, which act as Powerful inducements to stay in a service relatio
nship. Management implications for relational strategies and future researc
h implications of the findings are discussed.
