Political efficacy and trust: A report on the NES pilot study items

Political efficacy and trust—among the most frequently used survey measures of general political attitudes—are often maligned for their lack of reliability and validity. This paper reports results from the National Election Studies 1987 pilot study, which included more than thirty-five efficacy and trust items. Five attitudinal dimensions were hypothesized; four emerged clearly. One scale, internal efficacy, is especially robust; a four- to six-item scale represents a considerable improvement on existing NES measures. External efficacy is distinguished from political trust, at least when the former is measured in terms of the fairness of political procedures and outcomes rather than in terms of elite responsiveness to popular demands. Though less decisive, there also is support for dividing trust into incumbent- and regime-based components. The failure to find a similar incumbent- and regime-based distinction for external efficacy is in accord with theoretical perspectives.Revised version of a paper presented at the 1988 Annual Meeting of the Midwest Political Science Association.
