Clinical psychology is an integration of human science, behavioral science, theory, and clinical knowledge for the purpose of understanding, preventing, and relieving psychologically-based distress or dysfunction and to promote subjective well-being and personal development.
Psychoanalysis [i] is a set of theories and therapeutic techniques [ii] that deal in part with the unconscious mind, [iii] and which together form a method of treatment for mental disorders. The discipline was established in the early 1890s by Sigmund Freud , [ 1 ] whose work stemmed partly from the clinical work of Josef Breuer and others.
