Positive psychology is the branch of psychology that uses scientific understanding and effective intervention to aid in the achievement of a satisfactory life, rather than treating mental illness. The focus of positive psychology is on personal growth rather than on pathology, as is common among other frameworks within the field of psychology.
Positive psychology is a relatively new field of academic study with the first positive psychology summit taking place in 1999 and the first International Conference on Positive Psychology taking place in 2003.
The findings of positive psychology indicate that happiness is improved and affected in a large number of different ways. Social ties with a spouse, family, friends and wider networks through work, clubs or social organisations are of particular importance. Happiness increases with increasing financial income but reaches a plateau at which point no further gains are made. Physical exercise is correlated with improved mental well being as is living in flow and meditation.
The "positive" branch complements, without intention to replace or ignore, the traditional areas of psychology. By adding an important emphasis to use the scientific method to study and determine positive human development, this area of psychology fits well with the investigation of how human development can falter. This field brings attention to the possibility that focusing only on disorder could result in a partial, and limited, understanding of a person's condition.
The words, "the good life" are derived from speculation about what holds the greatest value in life – the factors that contribute the most to a well-lived and fulfilling life. While there is not a strict definition of the good life, positive psychologists agree that one must live a happy, engaged, and meaningful life in order to experience "the good life." Martin Seligman referred to the good life as "using your signature strengths every day to produce authentic happiness and abundant gratification."
Topics of interest to researchers in the field are: states of pleasure or flow, values, strengths, virtues, talents, as well as the ways that these can be promoted by social systems and institutions. Positive psychologists are concerned with four topics: (1) positive experiences, (2) enduring psychological traits, (3) positive relationships and (4) positive institutions. Some thinkers and researchers, like Seligman, have collected data to support the development of guiding theories (e.g. "P.E.R.M.A.", or The Handbook on Character Strengths and Virtues).
