Procedural Justice in the Courtroom: The Factor Structure and Psychometric Properties of the Revised Procedural Justice Scale

Abstract

In Polish psychology there has been no systematic research so far on the experience of contact with courts and on the evaluation of this experience using the theory of procedural justice. Polish psychologists do not have Polish instruments measuring procedural justice at their disposal. The Procedural Justice Scale is a measure operationalizing the dimensions of procedural justice according to Tyler’s model: respect, neutrality, voice, understanding, and influence. The aim of the present article is to present the work on the revised version of the Procedural Justice Scale, measuring procedural justice operationalized exclusively in psychological terms, and to present the psychometric properties of this scale. In particular, the author tested the reliability of the instrument and verified its validity based on confirmatory factor analysis, scale intercorrelations, and intergroup differences. The results confirmed the five-factor structure of procedural justice. They also confirmed the criterion validity of the measure, reflected in correlations with validation instruments.
