A measure of Psychological Capital (PsyCap) and its relationship with work performance, work well-being, and social well-being

This paper aimed to develop and validate a PsyCap measure (Luthans. 2002), and examine its relationships with outcomes. Data were collected among health care workers in Hong Kong and PRC by a longitudinal survey (N = 773 & 287 respectively). The results obtained by CFA supported a 22-item PsyCap scale measuring: self-efficacy, optimism, hope, and resiliency. Hierarchical regression analyses showed that PsyCap (Wave 1) predicted better work performance (job performance, injuries at work), better work well-being (job satisfaction, physical/psychological symptoms), and better social well-being (work-life balance, quality of life) (Wave 2). The construct and criterion validity of PsyCap were demonstrated
