The purpose of this study is to investigate the relationship between psychological capital and performance and to identify work family spillover and psychological well-being as a mediator of the effects of psychological capital on performance. Data was gathered from 361 white-collar employees from different occupations. The results based on Structural Equation Modeling reveal that psychological capital plays an important role in providing employees to have high performance. The results also indicate that psychological well-being and two dimensions of spillover (positive and negative work-family spillover) mediate the effect of psychological capital on performance. Implications of the results are discussed, and avenues for future research are offered.
