Should Psychosis Risk Become a Diagnostic Class in the New DSM-V? Proponents of the inclusion of psychosis risk, otherwise identified as a prodromal risk for psychosis, make the following points regarding a potential change within the new DSM-V. In this section, and the one following, all interpretations of the data from the literature are my own, although the source materials for my assumptions are notated as necessary. Although screening for psychosis risk is controversial, at the same time clinical work with respect to onset of psychosis needs some type of methodology for identification (Carpenter, 2009). This challenge might possibly be assisted by a diagnostic class which mitigates the weaknesses currently found within the DSM-IV;...The end:

(2009) is based on some very old studies from the 1940s and 1950s, which are not longitudinal, and are clearly based on doctor and educational records which do not contain explicit criteria for comparison. Even within the context of information which is presented by Welham et al. (2009), there were a number of environmental factors present which again are difficult to quantify or qualify. Additional studies are therefore needed to determine whether or not there is a specific means to assess whether prodromal risks for psychosis are able to be defined within the strict criteria that the DSM-V will naturally require.
