This paper aimed to examine perfectionism in information technology (IT) employees in terms of its effects on their positive and negative sense of well-being. In professional service firms, the intrinsic and extrinsic motivations of IT employees have become increasingly critical in determining organizational success. This study examines the relationship between perfectionism, job satisfaction, organizational commitment, and health problems among employees from the self-determination theory perspective. A total of 489 replies were used for the analysis of hierarchical linear model (HLM) techniques. The results revealed that perfectionism is significantly positively correlated with job satisfaction, organizational commitment, and health problems. Health problems negatively moderate the relationship between perfectionism and job satisfaction and between perfectionism and organizational commitment. The findings will provide references for professional service firm managers to retain valuable staff and improve service quality.
