The 1980s have been called the decade of anxiety. Not only is this true of the popular press, but students of behavior and psychopathology have contributed to the rather sudden reemergence of anxiety as a respectable and fascinating field of investigation. This volume is a culmination of more than two years of planning, literature reviews, writing, conference discussions, revising of original papers, and integrating the material for final publication. It is a series of interrelated statements about research on anxiety and the anxiety disorders written by many of the leading investigators currently active in this field. First published in 1985. Routledge is an imprint of Taylor & Francis, an informa company.
