In the contemporary organizational environment, understanding and developing different types of capital —human, social, and psychological— is essential for maximizing employee performance and well-being. Psychological capital (PsyCap) is composed of measurable and developable positive qualities, as self-efficacy, hope, resilience, and optimism, which significantly impact employee motivation and performance. This study conducted a state-of-the-art review to evaluate the effectiveness of PsyCap interventions. It reviewed 64 articles from the Scopus, ScienceDirect, and Web of Science databases, resulting in a final sample of 16 articles after removing duplicates and ineligible articles. The results indicate that PsyCap interventions promote the development of these qualities, improving psychological well-being and employee performance. Successful implementation of these interventions requires a clear understanding of workers’ needs and strong support from organizational leadership.
