The paper "Is the DSM-IV a Useful Classification System" is a great example of an assignment on health sciences and medicine. DSM-IV is the latest edition of the Diagnostic and Statistical Manual for Mental Disorders. After reviewing this manual, I have realized that DSM-IV has offered deep insight into the mental disorders. The possible mental disorders have been explained, and the diagnoses of these disorders have been justified based upon medical research and practices. The diagnoses of disorders have been justified on scientific grounds, and every proposal is based on technical grounds. The DSM-IV includes a series of case studies, research reports, and clinical interviewing techniques; the content of the manual are elaborative and detailed with a background. The critics have objected and protested that the manual has failed to incorporate some mental disorders; it is important to understand that the contents of DSM-IV are limited to the scientific and medical research conducted prior to its launch, therefore, it is unjustifiable to challenge the applicability and scope of DSM-IV on such grounds. The DSM-IV has offered possible solutions towards specific mental disorders, therefore the manual has provided a variety of solutions to resolve and handle a typical case of mental disorder. The critics have never challenged the contents of the manual; rather the discussion has been about the scope of the manual. The authenticity of the contents of manual is based upon medical and scientific journals; therefore this manual is not the product of human imagination rather it has been evolved on the grounds of reality, evidence, successful resolution towards specific mental disorders, research and development.
