Organization nowadays is facing hardship in maintaining the emotional and psychological aspects on the job performance quality as required by the organizations. In the field of organization behavior, it is very essential to examine the employees’ psychological aspects in order to know the real feelings and acceptance towards the perceptiveness of their job. This study was conducted to determine the impact of psychological capital (PsyCap) elements and work engagement towards job performance among assistant registrars in public universities in the Klang Valley area. From all the PsyCap elements, this research is solely focused on the four (4) elements; hope, optimism, self-efficacy and resilience, towards the level of their work engagement namely vigor, absorption and dedication and how it will give an impact towards their job performance; either it is in the role performance or extra role performance. This study adopts the quantitative research paradigm using the correlational research methodology. Data were collected from 214 Assistant registrars (or to the nearest grade) in 7 universities located in the Klang Valley area. These designated respondents were the representative of Malaysia public sector officers as intended by the researcher. Structural Equation Model (SEM) was employed to investigate the structural model of the study. Results from the direct effect analysis showed that the PsyCap elements, work engagement and job performance had significantly influenced each other except for the resilience and hope towards job performance. Specifically, these results suggest that psychological capital elements play an important role in determining the level of employees’ work engagement and how they can perform their jobs well wholeheartedly. The findings of this study largely support the hypothesized relationships proposed in the theoretical model especially the relationship between the PsyCap elements and mediating effect of work engagement. Employees with a higher level of psychological (mental) state are likely to have better work engagement and high degree of job performance capabilities. This study concludes that all research objectives are successfully answered and achieved. Future studies applying the proposed model are recommended to be conducted at other public agencies across Malaysia in order to verify these findings and to enrich the current literature on public officers especially on current issues that happen at the global level and the challenges in this era of the pandemic.
