Abstract

This study reviews and tests seven operationalizations of service quality to ascertain convergent validity. It compares these with earlier parallel operationalizations of job satisfaction, in order to assess the impact of the trait-method units common to both research domains. Results show that the service quality construct has limited convergent validity and further the construct does not explain a major portion of global service quality variance. Comparison of the service quality construct to the job satisfaction construct supplies some evidence of trait-method bias.
