Advances in the Psychology of Well-Being explores the cutting edge of psychological science in a world increasingly in need of hope, resilience, and meaning. This academic volume brings together leading research on how to measure well-being more effectively, examines populations where happiness and flourishing are especially vital, and redefines what it means to live a psychologically healthy life. Moving beyond a deficit-based model, this work calls for a future in which psychology prioritizes human potential, joy, and fulfillment over pathology alone. As global mental health challenges rise, the science of well-being offers not just solutions but a new direction. This is the future of psychology: one centered on thriving, not just surviving, a vital resource for today and tomorrow.
