The article analyses current research trends on psychological capital (PsyCap) in science and study institutions in the United States of America. The model of PsyCap, which is created by F. Luthans and colleagues, is introduced. The paper gives some evidence on how PsyCap components (self-efficacy, hope, optimism, psychological resilience) have been determined to meet the criteria of being state-like/open to development, being theory/research-based, having valid measurement, and having performance impact. Luthans and colleagues utility analysis of developing psychological capital has yielded a very high return on development. The paper discusses how the level of psychological capital could be linked to individual or organisational economic efficiency and what additional studies are required.
