Compare and contrast the categorical and dimensional approaches to diagnosis.
What will be an ideal response?
The categorical approach essentially requires a yes/no decision regarding diagnoses; a client either “has” or “doesn’t have” a disorder. By contrast, the dimensional approach essentially eliminates yes/no categories and replaces them with a dimension or continuum on which client’s system can be placed. The categorical approach has always been used by DSM, so it is more familiar at this point; also, it facilitates communication and research. The dimensional approach can produce more accurate client descriptions, especially when dimensions are readily identifiable (as is most true with personality disorders).
