RESPONSE VALIDITY IN SURVEYS OF VOTING-BEHAVIOR

This paper presents the results of a project which validated the reported registration and voting behavior of respondents in a national election study. The accuracy of reported voting behavior in the 1976 general election is assessed in terms of the demographic characteristics of the respondents to the Center for Political Studies National Election Study as well as the extent of their participation in a survey panel begun in 1972. Increased levels of registration and turnout are observed in association with the number of interviews in which respondents participated, and three alternative social psychological models of the effects of preelection interviews are evaluated. Although the interview apparently served as a stimulus to voting, neither a model associated with self-concept theory nor alienation theory appears to explain the phenomenon adequately. The interview effect is significant and appears to be cumulative, indicating that researchers usingthe survey method with panel designs should be sitive to the effects of their method on the behavior which they are tryingto measure. ©Public Opinion Quarterly.
