Justice Perception of Performance Appraisal
In 2010, Thurston developed the frame work to assess the justice perception of performance appraisal based on Greenberg’s proposed model for organizational justice of performance appraisal in the United States. This questionnaire includes 56 items in four main areas: procedural justice (17 items), distributive justice (12 items), interpersonal justice (10 items), and informational justice (17 items). It is also rated based on a 5-point Likert scale (from 5 = strongly agree to 1 = strongly disagree) with a total score of 280 where higher scores indicate higher perception of justice. Besides, any mean score above 3 (or a total score of 168-280) is interpreted as high perception, any mean score between 2 and 3 (or a total score of 112-168) is interpreted as average perception, and any mean score below 2 (or a total score below 112) is interpreted as low perception (8) (Table 1).
