Organizational psychology

Industrial and organizational psychology (also known as I–O psychology, occupational psychology, work psychology, WO psychology, IWO psychology and business psychology) is the scientific study of human behavior in the workplace and applies psychological theories and principles to organizations and individuals in their workplace.

I-O psychologists are trained in the scientist–practitioner model. I-O psychologists contribute to an organization's success by improving the performance, motivation, job satisfaction, occupational safety and health as well as the overall health and well-being of its employees. An I–O psychologist conducts research on employee behaviors and attitudes, and how these can be improved through hiring practices, training programs, feedback, and management systems. I–O psychologists also help organizations and their employees transition during periods of change and organization development.

I-O psychology is one of the 14 recognized specialties and proficiencies in professional psychology in the United States and is represented by Division 14 of the American Psychological Association (APA), known formally as the Society for Industrial and Organizational Psychology (SIOP).

In the UK, industrial and organizational psychologists are referred to as occupational psychologists and one of 7 'protected titles' and specializations in psychology regulated by the Health and Care Professions Council.

In Australia, the title organizational psychologist is also protected by law and is regulated by the Australian Health Practitioner Regulation Agency (AHPRA). Organizational psychology is one of nine areas of specialist endorsement for psychology practice in Australia. Graduate programs at both the Masters and Doctorate level are offered worldwide.

In the UK graduate degrees are accredited by the British Psychological Society and required as part of the process to become an occupational psychologist.
