Positive psychology is “the scientific study of what makes life most worth living,” or “the scientific study of positive human functioning and flourishing on multiple levels that include the biological, personal, relational, institutional, cultural, and global dimensions of life”. Positive psychology is concerned with eudaimonia, “the good life”, reflection about what holds the greatest value in life – the factors that contribute the most to a well-lived and fulfilling life.
Positive psychology began as a new domain of psychology in 1998 when Martin Seligman chose it as the theme for his term as president of the American Psychological Association. Mihaly Czikszentmihalyi and Christopher Peterson are regarded as co-initiators of this development. It is a reaction against psycho-analysis and behaviorism, which have focused on “mental illness”, meanwhile emphasising maladaptive behavior and negative thinking. It builds further on the humanistic movement, which encouraged an emphasis on happiness, well-being, and positivity, thus creating the foundation for what is now known as positive psychology.
