In March Sidney J. Blatt, Ph.D., professor of psychiatry and psychology and chief of psychology in the Department of Psychiatry, in collaboration with colleagues in Belgium, published a book, The Theory and Treatment of Depression: Towards a Dynamic Interactionism Model, that grew out of a collaboration begun in 2003. Blatt spent a month that year at the Catholic University of Leuven as a visiting professor. A colleague at Yale, Paul L. Errera, M.D., HS ’57, professor emeritus of psychiatry and a native of Belgium, sent greetings via videotape.
