Summary This survey comprises a national opinion poll conducted by the Waseda University 21st Century COE Program “Construction of an open political and economic system” and the 2007 W-CASI Study Group, from June 16 to July 11, 2007 (1st wave) and from August 25 to September 17, 2007 (2nd wave). It aims to clarify the attitudes, behaviors, and opinions of voters, male and female, aged 20 and older who comprised the survey subjects.

Specifically, the survey items included the following: attitudes and behavior in the Upper House election of July 2007, opinions about politics/political system/social system, forecast and evaluation of the economic situation and various new social problems that are occurring, etc.

In addition to these, in this survey, the survey design pays particular attention to the following points:
(1) Survey subjects were divided into two, and half the survey was conducted using the CASI method (Computer-Assisted Self-administered Interview) on laptop computers, and the other half of the survey was conducted using the conventional interview method PAPI (Paper and Pencil Interview). In principle, by asking the same question, it was possible to analyze the difference in answer distribution by survey mode.
(2) In the CASI method, by utilizing CGI and Adobe Flash, a survey environment was constructed, which is more dynamic and interactive than conventional surveys.
(3) By using the technology of (2), it was possible to reduce the burden on respondents, measure the response time to each question item and the interruption time during the survey, and measure the degree of burden to respondents by question items, more effectively than when using the conventional survey method of researchers conducting interviews.
(4) Applying the CASI method, it became possible to conduct the experiment using samples with external validity, which in the past was done by gathering the subjects in a laboratory and using the Internet.
(5) A small preliminary test was conducted beforehand, and fine adjustments were made to the way of asking questions and arranging the screens.

The national opinion poll, which is being conducted continuously and which includes this survey, comprises the following:
