Psychology Diagnosis and DSM-IV

The main purpose of the DSM-IV is to provide a modern classification system for abnormal behavior and psychological disorders Comer, 2008). Put simply, it helps clinicians diagnose a disorder. The system lists over 400 disorders with criteria for diagnosis. The clinician evaluates five axes of information before determining a diagnosis (Comer, 2008). Another important aim of this classification system is to provide a sort of standardization for diagnosis. While it is not something that requires adherence, it represents common ground for clinicians to utilize, discuss, and ultimately learn more about diagnosis.

So, how much value is created by the aims of such a classification system? To answer this, it is important to evaluate the reliability and validity/accuracy of the system. DSM-IV serves as a revised version of previous DSM classification systems. With new diagnostic criteria and more research, reliability has increased. Reliability adds value because it is important to have a dependable diagnosis. Clinicians will be more likely to use the system and the system itself will be a consistent aid. In addition, promoting accuracy of information provides value. The DSM-IV system increased validity of information through extensive review and studies. The result is quality data and information that can be used in the diagnostic process. These to factors lead to a system that is the most widely used in the United States (Comer, 2008). This is perhaps the greatest value of such a system. To have a system that is widely accepted and creates a common starting point for diagnosis provides many advantages. It ultimately helps further the study of psychological disorders through collective efforts instead of only individual ones.
