Categorical Approach to Diagnosis

`In the past, I worked in such a research setting, where if a person was found to meet criteria for opiate dependence they received treatment, however if even slightly short of DSM-IV criteria for the disorder they would have to look elsewhere. This was a continual concern for me, as the person who met criteria was not always the person with the most distress, and alternative treatments were not easy for people to find. Largely from this experience, I find the current categorical approach to classifying persons with psychopathology to be an imperfect system at best, with the primary advantage of being convenience when communicating with other professionals. I question whether this convenience comes at a severe cost to accuracy, the result of which is an artificial limit to the range of presentations that occur in psychopathology. As the example above illustrates, the particular aspect that I find most problematic is the use of cutoffs for specific symptoms, for instance the length symptoms must have been present for it to be classified as a disorder, or even the number of symptoms that need to be present. I think it is unlikely that a person who “almost” meets criteria for a disorder would be significantly different from a person with similar symptoms who just barely meets criteria. In private practice these two cases would likely be treated similarly, but in a setting where diagnosis serves as a screening tool the client who met criteria may get treatment while the other does not. In this case I feel that less specific guidelines, lacking specific numerical limits would alleviate many of the problems. A separate, but related problem is in the accuracy of the diagnosis in identifying a discrete pattern of pathology. I... ... middle of paper ... ...uld be used in therapy. The obvious limitation to this lies in the ease of transmission of information to other professionals. I feel that limitation is not a serious problem, however, as the usefulness of information given by a diagnosis is questionable. I do, however, concede an serious advantage to the categorical diagnosis in training and research on treatment. It would be impossible to train students in the entire range of presentations that can occur, and having a limited range of diagnoses provides a good foundation for conceptual groupings. Being able to use these groupings for research also fosters better training. This is the one area in which I feel that categorical diagnosis is a requirement. In conclusion, I would find the ideal system to be training using a categorical system, but within the context of actual application a more descriptive system.
