Outline of the evolution of quality of life psychology

Psychological well-being is treated in psychology as a constitutive element of quality of life, expressed in a subjective aspect, determining the satisfaction of the individual with personal life, or also treated as a synonymous term. Most psychological theories focus on the subjective approach, in which quality of life is understood as psychological well-being units (Bartosz, Klebaniuk, 2006; Czapiński, 2008;, Derbis, 2000; Diener, Lucas, Oishi, 2008; veenhoven, 1996, 2005; Zalewska, 2003). In this perspective, various aspects of life are assessed from the perspective of the individual who performs the assessment process using their own individual criteria. Mental well-being indicates an individual experience of contentment and happiness in life. This assessment includes both cognitive judgments about the sense of satisfaction and fulfillment, as well as emotional responses to occurring events. In this sense, psychological well-being is a broad concept that enables people to make judgments about their lives, instead of relying on external quality assessments of their own lives.
