Q: I am interested in the taxonomy of the accepted usage of psychological diagnostic terms, both with reference to individual psychology as well as to interpersonal, or social, psychology. I am interested in the hierarchical structure of various terms as they relate to each other. This is to say that I am interested to know which of the various terms contain other of the various terms. All of the terms that I am interested in are related to disorders, illnesses, or dysfunctionalities. Please provide me with several such terms, their meanings, and describe the relationships of these terms, each to each others.
