環境リスク研究におけるweb調査の有効性

抄録

Web survey had become popular method not only in business but academics. The validity of web survey for academic use, however, was not confirmed. In this study, responses of two questionnaire surveys, one was interview survey and the other was web survey, were compared to investigate the effect of survey methods. The results showed that respondents of web survey revealed lower concern about environmental problem and nuclear power plant problem, while there were little differences in risk perceptions. This difference was not explained by the bias in the demographic characteristics between two surveys.
