A four-item Likert-type scale measuring the degree to which a person perceives a website's information-handling and advertising procedures to be fair, covering transparency of procedures, honesty with visitors, user control over personal information, and fairness of advertising and privacy practices. The scale operationalises procedural justice in online contexts — the perceived fairness of the processes by which a website collects and uses visitor data — rather than the fairness of exchange outcomes. Schumann, von Wangenheim, and Groene (2014) drew on concepts and phrasing from Wirtz and Lwin (2009) and used the scale in Study 1 alongside the Website Distributive Justice Scale (id:627) to examine consumer acceptance of targeted advertising. Administered in German via back-translation. Alpha = .89 and AVE = .58 indicate good reliability and acceptable convergent validity.

The scale was administered in German in the original study. AVE = .58 is above the conventional .50 threshold but at the lower end of acceptable; researchers should verify convergent validity in new contexts. Discriminant validity from related constructs was demonstrated by Schumann et al. (2014). The procedural justice items address information transparency, honesty, user control, and advertising/privacy fairness — four distinct but related procedural concerns. In research where separating these sub-facets is theoretically important, item-level analysis or an expanded instrument may be warranted. Use alongside the Website Distributive Justice Scale (id:627) when both outcome and process fairness are relevant, as the two are conceptually and empirically distinct.
