Positive psychology is a branch of psychology focused on understanding and enhancing well-being, resilience, and the aspects of life that contribute to human flourishing, contrasting with traditional models that emphasize pathology. Key concepts include the PERMA model, which outlines five elements of well-being: positive emotions, engagement, relationships, meaning, and accomplishment, as well as the distinctions between eudaimonic and hedonic well-being. The field also emphasizes the integration of positive psychology in therapy and prevention, particularly through technological advancements to enhance well-being and resilience.
