Alternative measures of political efficacy: models and means

In the 1982 and 1984 American national election surveys the CPS deleted a subset of its longstanding measures of political efficacy. This paper employs covariance structure analysis to test a two-factor measurement model based on alternative indicators. The model has an excellent fit for data from the 1964–84 national surveys as well as for different educational, gender, and racial groups in the 1984 study. Consistent with previous theorizing, the internal efficacy factor is significantly more stable than the external factor. Also, the two efficacy factors correlate as expected with measures of general personal competence and political trust. The paper is the first to use LISREL structured means tests to test group differences in levels of efficacy or other important political attitudes. Since this technique is not well-known, a tutorial appendix describing its implementation in LISREL VI is included to facilitate future research.
