Performance appraisal satisfaction is the extent to which the employee perceives performance ratings, which reflect those behaviours that contribute to the organisation. Even though performance appraisal satisfaction is the most frequently measured appraisal reaction, there are relatively few meta-analysis studies which link determinants of appraisal system to satisfaction with employee performance. The focus of this research is to examine the determinants affecting employee performance appraisal satisfaction in the Brunei public sector using data collected from among public sector employees, with particular emphasis on how performance is viewed and measured in the public sector. Data for this research were gathered across ten government ministries in Brunei. This research study adopts a 'mixed method approach', which utilises quantitative data supported by qualitative data. The qualitative interviews involved 14 participants, while the main quantitative data had 355 samples. Quantitative data was analysed using descriptive analysis and exploratory factor analysis run on SPSS, while confirmatory factor analysis, path analysis and structural equation modelling were also employed on applied analysis of moment structure (AMOS) to assess the model fit of the study and hypotheses testing. Results indicated that latent constructs (goal-setting and the purposes of performance appraisal; alignment of personal objectives with organisational goals; fairness of the appraisal system; types of performance evaluation measures; format of rating scales; appraiser-appraisee relationship and credibility of appraiser; in-group collectivism; power-distance; and pay-for-performance constructs) were positively and significantly correlated to performance appraisal satisfaction. The results also showed that the goodness of fit indices offered an acceptable fit to Brunei's data. The study findings advance current knowledge in the performance management domain by extending individual level theory of performance appraisal satisfaction and provide empirical evidence for performance appraisal and employee satisfaction at the individual level in the public sector. This study contributes theoretically by highlighting the unique effects of latent factors on employee performance appraisal satisfaction. The research also contributes in terms of methodology, in that this study contributes to the examination of the predictors of established models of performance management in a country which is culturally different from the environments in which these constructs were developed. This research has filled gaps by testing predictor variables in cross-cultural work settings, which may be useful in generalising these predictors. Furthermore, the examination of the conceptual framework using structural equation modelling is a methodological contribution in its own right. The presence of multivariate normality encourages the assessment of the measurement model by a confirmatory factor approach, using maximum likelihood estimation, which is an additional contribution to the method analysis.
