WE present Psyclops, an interactive computer graphic system designed t
o help address a growing information dilemma in the examination of ind
ividual psychiatric cases. Ever more information is needed to better u
nderstand conscious experience, interpersonal behavior, and the format
ion of psychiatric signs and symptoms, yet the information load alread
y exceeds our usual methods of handling it. Psyclops consists of a sui
te of software modules, manual sections, and standards that have been
developed according to guiding concepts intended to help one collect,
organize, access, and explore complex data about a single subject for
research, education, and ultimately, clinical care purposes. This docu
ment provides background in clinical information science and a descrip
tion of the system; the reader interested in its application in clinic
al research theory development is referred to the companion paper in t
his issue (Horowitz et al., Pathological Grief: An Intensive Case Stud
y).
