Abstract

performance appraisal system is important in achieving effective
performance appraisal results. Therefore, this study aimed to evaluate
the psychometrics of the Persian version of the Justice Perception of
Performance Appraisal (JPPA)instrument.
Methods: In this methodological study, 301 clinical nurses
working in the hospitals affiliated to Shahid Beheshti University of
Medical Sciences were selected based on purposive sampling. The
translation and validation of the justice perception of the performance
appraisal framework were sought according to the instructions proposed
by the University of Incarnate Word in the United States. The
psychometric characteristics of the instrument including construct
validity (exploratory and confirmatory factor analysis) and reliability
were evaluated using internal consistency based on Cronbach’s alpha
index and intra-class correlation (ICC). In the present study, SPSS
version 17 and LISREL software version 8.8 were used for confirmatory
factor analysis.
Results: The results of the exploratory factor analysis
indicated the establishment of these four factors: procedural justice,
distributive justice, interpersonal justice and informational justice
which covered 57.71% of the total variance. The results of the
confirmatory factor analysis confirmed the appropriateness of the
four-factor construct of the justice perception of performance appraisal
(p = 0.000, X2 = 4184.26, df = 1478, GFI = 0.67 &
AGFI = 0.64, RMR = 0.11, SRMR = 0.078, &RMSEA = 0.078, NFI = 0.95&
NNFI = 0.97, and CFI = 0.97). The internal consistency of the instrument
was also confirmed according to the Cronbach’s alpha index of 0.97 and
the intra-class correlation index of 0.95.
