The Task Froce on DSM-IV and members of the DSM-IV Work Groups have chronicled their efforts and the results in the DSM-IV Sourcebook, which documents the rationale and empirical support for the text and criteria sets presented in DSM-IV. This third of five volumes concludes the DSM-IV literature reviews, and summarizes the DSM-IV Work Group efforts that led to publication of the DSM-IV Options Book. Each review contains the following six sections: Statement of the Issues, which frames the importance of each issue and discusses its clinical and empirical significance; Methods - which documents the extent to which the reviews were systematic and comprehensive in their coverage of the literature; Results - which provides an objective and thorough summary of the clinical research findings for DSM-IV; anad Recommendations - which offer recommendations for DSM-IV, based on the review of the literature.
