Reliability Questionnaire Result by the Difference of the Information-Giving System

Abstract

This study analyzes the degree of change in AHP questionnaire results based on the difference in the examinee's knowledge of the evaluation object. First, the AHP questionnaire is administered three times to the identical examinees. For each administration, the system of providing information differs. The three systems for imparting information are ① a text description; ② a text description, a photograph and a map; ③ and a field inspection. The comparison of the questionnaire results showed that evaluation based on a text description and a photograph had almost the same value as the evaluation based on the field inspection.
