The field of Clinical Psychology integrates science, theory, and practice to understand, predict, and alleviate maladjustment, disability, and discomfort as well as to promote human adaptation, adjustment, and personal development. Clinical Psychology focuses on the intellectual, emotional, biological, psychological, social, and behavioral aspects of human functioning across the life span, in varying cultures, and at all socioeconomic levels.

Clinical psychology is a speciality of psychology that focuses on the application of scientific principles and practices, including diagnosis, assessment, intervention, and treatment, to clients experiencing mental disorders or deficiencies. Clinical psychologists may also work in other settings, such as academic settings (as a professor or researcher), forensic settings (as a forensic psychologist), or private practice. The subject is similar to medicine, sociology, and pedagogy.[1][2]
The field of clinical psychology is considered to have been formally founded in March 1896 when American psychologist Lightner Witmer founded a psychology clinic at the University of Pennsylvania as a response to several local children suffering from a variety of mental deficiencies, including spelling[3]. For his pioneering contributions, he is considered to be the founder of clinical psychology.[4]
To be a clinical psychologist, one must attain a doctoral degree (either a PsyD or a PhD) and pass the ERPP. Other requirements include supervisor hours, state board approval, and a [separate] ethics exam.
