DSM is the accepted standard of psychiatric diagnosis, particularly in the US, currently undergoing the revision to be called DSM-V. The inclusion of the term “statistical” in the titles of DSM-I and DSM-II reflected only the fact that the original intent was to develop a classification in order to count cases, not that any statisticians were involved. However, with DSM-III, statistical considerations, particularly those associated with methods to establish reliability and perhaps validity, began to influence DSM. In DSM-IV, meta-analysis came into play. The first conference in preparation for DSM-V revisions focused completely on statistical issues. Dr. Kraemer was a consultant for DSM-IV and is on the Task Force for DSM V, and will discuss directions and influences that biostatistical considerations may have in the DSM future.
