Valid and Reliable Measures of Generalized Trust: Evidence from a Nationally Representative Survey and Behavioral Experiment

Abstract

Generalized trust has been one of the most frequently examined constructs since researchers first introduced measures of it in the 1940s. Despite its significance, there is a growing consensus that traditional measures of generalized trust are prone to measurement invalidity and nonequivalence, calling into question sociological knowledge about generalized trust. In this article, I advance trust research in sociology by (1) refining two new self-report measures of generalized trust—the Stranger Face Trust scale (SFT) and the Imaginary Stranger Trust scale (IST)—and (2) assessing their empirical performance on a nationally representative probability sample (N = 1,264). I compare the reliability and validity of SFT, IST, and traditional measures of generalized trust across a range of measurement validation tests. Results suggest that SFT provides the most accurate and consistent measure of generalized trust.
