RT Journal Article SR Electronic T1 A proposal to classify happiness as a psychiatric disorder. JF Journal of Medical Ethics JO J Med Ethics FD BMJ Publishing Group Ltd and Institute of Medical Ethics SP 94 OP 98 DO 10.1136/jme.18.2.94 VO 18 IS 2 A1 R P Bentall YR 1992 UL http://jme.bmj.com/content/18/2/94.abstract AB It is proposed that happiness be classified as a psychiatric disorder and be included in future editions of the major diagnostic manuals under the new name: major affective disorder, pleasant type. In a review of the relevant literature it is shown that happiness is statistically abnormal, consists of a discrete cluster of symptoms, is associated with a range of cognitive abnormalities, and probably reflects the abnormal functioning of the central nervous system. One possible objection to this proposal remains--that happiness is not negatively valued. However, this objection is dismissed as scientifically irrelevant.
