From the first volume published in 1968, the Annual Progress series has set the standard for the field in its yearly compilation of outstanding contributions to the literature. Rich in diversity and scope, this 31st annual edition of Annual Progress continues to provide the most up-to-date research and scholarship available in the field of child psychiatry and child development. Under the judicious editorship of Drs. Hertzig and Farber, this volume is comprised of 20 articles that illuminate groundbreaking work in the study of the child to present a clear, thoughtful, and systematic picture of child psychiatry and development. The articles cover developmental issues, clinical problems, treatment, including the use of light therapy, and psychosocial issues. The 1998 edition of Annual Progress remains a benchmark against which all other contributions to the literature will be measured. Mental health professionals who work with children and adolescents will find this book invaluable for both its timely information and long-term reference value. Researchers will find substantial information in its pages for new spheres of inquiry.
