The main purpose of this study attempted to develop the scale of service quality for hand-prepared beverage stores and to verify its content validity, criterion validity, discriminant validity, and reliabilities of consistency and equivalence. Based on SERVQUAL scale, interviews and experts' opinions, a service quality scale for hand-prepared beverage stores was generated. The pilot study was conducted to help revise the formal questionnaire. Questionnaires with the scale were then distributed in a university and in a hand-prepared beverage store, CIRCUS, which was next to the campus of the university in the middle of Taiwan. Those students who had ever visited CIRCUS were recruited to answer the questionnaires. Totally, 200 valid questionnaires were returned with 82 males. For criterion validity, a similar scale, satisfaction, was used. The analyses of Pearson correlation coefficient were used to examine the discriminant validity. The confirmation of consistency reliability adopted Cronbach Alphas. For verifying the reliability of equivalence, the sample was first randomly divided into two groups, and then their average scores in the service quality and the five dimensions were compared. The results showed that the service quality scale for hand-prepared beverage stores met the validity and reliability. Future studies are encouraged to adopt this scale for similar stores. The course of research methods may use this paper in class as reading material of a real case.
