New in paperback. Hardcover was published in 2023. Despite broad interest in how children and youth cope with stress and how others can support their coping, this is the first Handbook to consolidate the many theories and large bodies of research that contribute to the study of the development of coping. The Handbook's goal is field building - it brings together theory and research from across the spectrum of psychological, developmental, and related sciences to inform our understanding of coping and its development across the lifespan. Hence, it is of interest not only to psychologists, but also to neuroscientists, sociologists, and public health experts. Moreover, work on stress and coping touches many areas of applied social science, including prevention and intervention science, education, clinical practice, and youth development.
