A developmental approach to psychopathology based on the theory that a continuum of growth underlies all psychological processes which is manifested in a sequence of developmental stages. The book views psychopathology as a consequence of inappropriate resolution of various problems at one or more stages of development. Using this unifying framework, it reviews more than 25 years of research considering such topics as: premorbid social competence, symptomatology diagnosis, the paranoid-nonparanoid distinction in schizophrenia, the essential- reactive distinction in alcoholism, the course and outcome of psychiatric disorders, and the developmental differences in self- image. 9,000 references are included in the book.
