Abstract (in Japanese) (See Japanese page) 
(in English) Recommender systems have been used in many online services. People may have come to accept the recommended items without any consideration. We call such an attitude of users toward recommender systems "recommendation overtrust". We have developed a psychological scale to measure whether users fall into recommendation overtrust or not. In our previous paper, a questionnaire survey has been conducted to verify its validity on a crowd sourcing service. In this paper, we conducted a factor analysis of the responses obtained from the survey for clarifying the main concepts that constitute recommendation overtrust. In addition, in order to verify the validity of the found subscales, we examined the relationship between other psychological measures related to trust and the tendency to use the target service. The results showed that the proposed scale and its subscales were correlated with two perception indices of TAM (Technology Acceptance Model) and the usage frequency of the service.
