Justice-related satisfaction was measured with four items (cf.
Gollwitzer et al., 2011) that focused on cognitive aspects of justice
achieved and psychological closure (“Now I experience a sense of
closure,” “Everyone got what they deserved,” “Everything turned
out to be satisfactory for me,” “Justice has been restored;” Cronbach's
α = .62). Regret about revenge was assessed with the same 3-item
scale that was used in Studies 1 and 2. Unfortunately, the internal
consistency of this scale turned out to be very low (Cronbach's
α = .50). Ratings for both scales were made on a 6-point Likert
scale ranging from 1 (strongly disagree) to 6 (strongly agree).
