According to Parasuraman et al. (1991)‚ this questionnaire has been the most widely used to assess the perception of service quality. The SERVQUAL includes the five subscales: Tangibles described as the concepts of “physical facilities‚ equipment‚ and appearance of personnel‚” Reliability described as “ability to performance the promised service dependably‚” Responsiveness described as “willingness to help ustomers and provide prompt service‚” Assurance described as “knowledge and courtesy of employees and their ability to inspire trust and confidence‚” and Empathy‚ which has been defined as “caring‚ individualized attention the firm provides its customers”.
the response format for this instrument was a 7-point Likert-type scale‚ with responses ranging from 1 (Strongly Disagree) to 7 (Strongly Agree).
