Measuring the Construct of Warranting Value and Testing Warranting Theory

<jats:p> Warranting theory has been used extensively to explain how people evaluate information across a variety of online settings. However, no validated measurement instrument exists to assess the construct of warranting value that is at the core of the theory. Two studies were conducted to develop and validate a General Warranting Value Scale and three scales that assess specific forms of information control: Modification Control, Dissemination Control, and Source Obfuscation. In addition, we tested predictions of warranting theory using multiple stimuli and samples—including a nationally representative sample of adults. Overall, evidence for scale validity was obtained: Confirmatory factor analyses were consistent with measurement model fit. All scales were sensitive to theoretically predicted manipulations and were correlated with theoretically predicted outcomes. </jats:p>
