Panel Survey Design

□ Panel Survey Design

The 2007 Presidential Election Panel Survey will vividly analyze the shifting voter preferences surrounding the presidential election over eight months, from late April before candidate selection, through the nomination of candidates by each party and the main competition, until the final vote in December, with a total of six survey waves. In particular, it is expected to scientifically reveal the dynamics of electoral behavior, such as voters who supported a specific candidate changing their support or undecided voters who did not support any candidate coming to support a specific one.

Furthermore, the 2007 Presidential Election Panel Joint Research Team aims to significantly contribute to correcting the existing misunderstandings about voter perceptions and attitudes by fully leveraging the advantages of panel surveys. Panel surveys are expected to be of great help in accurately understanding the impact of changes in voters' values and ideological attitudes on their political choices.

- Survey Period

This study, as a survey methodology for constructing the first large-scale presidential election panel survey data in Korea to track individual-level political perceptions and attitude changes during the 17th presidential election campaign period, will conduct a panel survey over a total of six waves by constructing a panel according to the following principles. Here, 'election campaign period' refers to the period from the preliminary candidate registration on April 26, when the presidential hopefuls begin their full-fledged activities, until the end of the general election on December 16.

- Questionnaire Design

The survey will be conducted using a closed-ended, structured questionnaire, and the questions will be divided into two categories: (1) core questions and (2) focused research questions. Core questions refer to questions that repeatedly track changes in the factors influencing voting decisions, which is the core task of this study.

The core tracking questions that will intensively track public opinion changes over the six survey periods consist of ① candidate factors, ② party factors, ③ election campaigns, and ④ attitudes toward issues and policies (refer to [Table 4] for detailed question items). The questions will, as much as possible, align with the wording of international surveys such as the ANES questionnaire to enable international comparisons, but if the questions are not suitable for the Korean election reality, new questions will be developed and used.
