초록

본 연구에서는 리커트 5점 척도 설문에 참여했던 응답자들이 특정 자극에 의해 동일한 2차 설문이 주어졌을 때, 본인의 처음 응답결과를 어떻게, 어떤 방향으로 바꾸는지를 측정하고자 하였다. 이를 위해 3개 설문지의 1차, 2차 또는 3차에 걸친 재설문 결과들을 집단간 차이, 자극의 종류, 설문목적의 차이, 응답변화의 방향 및 변화정도의 관점에서 분석하였다. 본 연구를 통해 발견된 연구결과는 다음과 같다. 첫째, 전문가 집단과 일반 집단 중 전문가 집단이 상대적으로 의견을 바꾸지 않는 것으로 유의하게 검증되었다. 둘째, 설문목적에 따른 차이는 없는 것으로 조사되었고, 자극의 종류 중 시스템 사용경험보다는 다른 사람들의 의견이 정보로 주어졌을 때 더 많은 영향을 받는 것으로 나타났다. 셋째, 최초응답에서 긍정적인 답변에 응답했을수록 답변을 바꾸지 않는 것으로 나타났고 부정적인 답변자는 대부분 긍정적인 방향으로 의견을 바꾸는 것으로 유의하게 검증되었다. 넷째, 최초 응답을 바꾸는 경우 응답변화의 폭이 2단계 이상인 경우는 그다지 많지 않고 대부분 1단계 정도 전후로 바꾸는 경향이 있는 것으로 분석되었다. 마지막으로 중간응답자가 의견을 가장 많이 바꾸고 양극단의 경우 의견을 잘 바꾸지 않을 것이라는 예측을 하였으나 부정적인 답변자일수록 의견을 긍정적인 방향으로 바꾸는 것으로 분석되었다.

This study examines how and which direction respondents who participated in 5-point Likert scale surveys change their initial responses when they are given an identical second survey after certain treatments. The research employs three identical questionnaires (first, second and third surveys) to analyze survey results based on group differences, kinds of treatment, survey purposes, and response change direction and the degree. This paper concludes that, first, it is significant that specialist groups do not change their initial responses compared to a general librarian group. Second, there are no differences by survey purpose; however, participants tend to change their initial responses by others' opinions rather than by previous use experiences. Third, participants who initially answered positively tend not to change their responses, and most participants who answered negatively change their initial responses in a positive direction. Fourth, when there are changes, participants change their initial responses by less than two points, and most of them change by one point. Finally, the hypothesis that middle responses change most and that participants who respond at both ends do not change their opinion was rejected by the finding that participants who answered on the negative end tend to change their initial responses in a positive direction.
