Document Summary
We need ways of diagnosing abnormality to help the patient, based on a classication system. The perfect diagnostic system would classify disorders on the basis of sound empirical research findings of symptoms, etiology, prognosis / diagnosis, and response to treatment. Different symptom clusters would accurately signal different disorders. A precise cure would be available for each disorder. The perfect diagnostic system is difficult to attain. It is hard to systematically observe and measure human functioning in a controlled manner. Classification systems are useful to organize information, communicate, recommend treatment, for prognosis, for heuristic value (i. e. : learning from experiences), and for guidelines for financial support. We are too unique, too individual, too dynamic, etc. In most circumstances, we can only treat symptoms. In the 19th century, he developed systematic classification. The american psychological association (apa) published a classification system, the dsm-i in. 1952, dsm-iii in 1980, and dsm-iii-r in 1987.
