A Study on the Determinants of Perceived Service Quality:-Focused on the Comparisons of SERVQUAL, SERVPERF and Non-Difference Scores-

해외여행상품의 서비스품질척도의 비교 및 만족. 재구매의도에 관한 연구

After SERVQUAL was proposed as a measure of perceived service quality, several arguments have been made against its validity and some competing measures have been developed. This paper reviews those controversies. Particularly, it compares the concept of expectation in the research of service quality with that in the research of satisfaction, re-purchase intention and suggests the authors' opinion. In addition, the paper suggests sequential casual relations among expectation, perceived performance and perceived service quality. With the help of previous researches concerning "SERVQUAL" and the related topics, six variables concerning travel services were identified. The six variables are tangibility, reliability, responsiveness, assurances, empathy and costs. Seven hypotheses were developed using these variables. The review of literature covers service's concept, model and method of service quality evaluation, and relationship among the concepts which is related to the service quality. The results of our study suggest further research is necessary to clarify which one is a better tool because we have a conflicting research outcome in terms of model fitting. The study also shows that assurances and costs have positive effect on customer satisfaction. It also turned out that customer satisfaction has positive effect on repurchase intention.

본 연구의 첫 번째 목적은 Service Quality를 측정하는데 있어서 기대와 성과 측정치를 차감하는 차감식(Difference Score)에 의한 방법 (SERVQUAL), 지각된 성과만으로 개념화/조작화 하는 방법(SERVPERF), 차이를 한번에 직접 측정하는 방법 (non -difference score)중 어느 방법이 가장 타당한지를 조사하는 것이다. 본 연구의 두 번째 목적은 서비스품질 construct가 만족과 재구매의도에 대한 선행변수로서 갖는 이론적 가치를 조사하는 것이다. 부산, 경남의 376명의 60세 이상의 해외여행경험이 있는 노인들을 대상으로 설문조사가 이루어 졌다. 연구결과 SERVQUAL, SERVPERF와 비차이척도를 이용하는 방법의 비교결과 모델적합도를 나타내는 지수가 상충되게 나타났다 만족과 재구매의도에 미치는 영향력에 있어서는 대부분의 서비스품질 선행 구성변수들이 유의적인 영향력을 갖고 있는 것으로 나타났다.
