As the release of the new Diagnostic and Statistical Manual V (DSM V) approaches, questions arise on the impact to clinical work in related fields. The revision of the manual has taken place over the last fourteen years with commentary and feedback from varying groups such as consumers, family members, treatment providers and researchers. Rigorous field studies composed of representative groups have been carefully analyzed in the comprehensive attempts to improve this important, essential book. The organization of the DSM V will take the form of chapter sequences that state both vulnerabilities and symptoms to disorders. Developmental lifespan issues will be integrated into every chapter. There will be twenty chapters with some new conditions being considered and others being dropped. Reliability and prevalence data from the field trials has established this dimensional rather than categorical approach to accurate diagnoses.
