Editorial Review:

For over six years the DSM-IV Task Force and members of the DSM-IV Work Groups have participated in a comprehensive effort of empirical review leading to the publication of the fourth edition of the American Psychiatric Association& rsquo;s Diagnostic and Statistical Manual of Mental Disorders (DSM-IV). This first volume of the DSM-IV Sourcebook chronicles these efforts and their results, documenting the rationale and empirical support for the text and criteria sets presented in DSM-IV. From a total of five volumes, the first three contain the DSM-IV literature reviews and summarize the DSM-IV Work Group efforts that led to the publication of the DSM-IV Options Book.
