This volume is one of the first to concentrate on positive growth and development in a clinical arena, rather than loss and pathology. In contrast to the general theories and cross-sectional studies of existing adult developmental research, much of this volume looks at the whole-life level of development of adults through case studies. The book unites three compatible approaches to the study of adult development. The first considers the development of whole life. The second approach examines behavior during certain periods in adults’ lives by combining clinical and developmental stage perspectives. The third approach examines periods of life following the work of Erikson, Levinson, and Vaillant. The editors of this volume believe that these three approaches form, in their synergy, a comprehensive and multifaceted approach to uniquely difficult problems of late adolescence and early adulthood. It is the unification of these three approches that makes this book unique in its field.
