Researchers proposed new diagnostic model for psychiatric disorders” reports on the work of a consortium of 50 psychologists and psychologists around the world who are developing a new diagnostic model to replace the DSM 5.  They view the SM five as “far too conservative” and as failing to “recognize and incorporate important scientific evidence.”

Their new model, called the Hierarchical Taxonomy of Psychopathology (HiTOP) differs from the DSM in two fundamental ways: it is dimensional, rather than categorical, and uses empirical evidence classify disorders.” For example, generalized anxiety disorder is classified as more similar to major depression than specific phobia, based on evidence that finds that most people with GAD also meet criteria for MDD.
