Purpose. Psychological Capital (PsyCap), consisting of hope, efficacy, resilience, and optimism, is a positive state associated with attitudes, behaviors and performance.

Job satisfaction and job performance represent two of the most important and

a large sample of employees who were followed for five years (N51,004). The
