It is generally agreed that the relationship quality (RELQUAL) in business exchange situations is important. However, there does not appear to be a consensus on the conceptualisation and measurement of the many dimensions of this construct. This may be due to the difficulty in measuring many dimensions in one empirical study. This raises a concern regarding the understanding of the interaction among the various dimensions. Using data gathered in a survey of Canadian managers and executives the present study investigates how focal dimensions pertaining to RELQUAL inter-relate. A model consisting of the following ten dimensions derived from RELQUAL literature was tested: continuity, satisfaction, trust, commitment, opportunism, cooperation, coordination, formalisation, dependence, specific assets. All recommended guidelines for convergent, discriminant and nomological validity, as well as construct reliability, were met. Copyright © 2012 Inderscience Enterprises Ltd.
