Perceived Quality of Online Self-Service: Validation of the E-Selfqual Scale in the Brazilian Context

Abstract

In face of a competitive virtual market, driven by the growth of online shopping and the increase in the number of retailers in this modality, measurements to evaluate the quality of online service become important, particularly due to the identification of a positive relationship between service quality and service performance. In this sense, Ding et al. (2011) proposed a consistent measure of the perceived quality of service in electronic commerce from the perspective of self-service: the e-SELFQUAL. This paper presents results of the replication of e-SELFQUAL in the Brazilian context. Two data collections were carried out: first, for a final sample of 106 students, there was an inadequacy in a construct of the scale, and a new translation was proposed. A second collection was applied to a sample of 175 people. The results confirmed the reliability and validity (convergent and discriminant) of the scale, keeping the original items of the instrument. The findings indicate possible use of the e-SELFQUAL to measure the quality of online self-service in Brazil.
