This research takes as it subjects all patients in a hospital being studied. It seeks to understand the factors that contribute to the psychiatric patients' tendencies in selecting space and to how they relate to others through their use of shared space and their observed behaviors. Findings are as follows;
1.The patients' selection of space were affected by “intrinsic elements” such as the type of patients they were and the number of days of their hospital stay, in addition to “extrinsic elements” such as the type of hospital room, the space's continuity with staff stations, and the arrangement of the space.
2.Tendencies in behaviors and relationships with others were frequently influenced by “intrinsic elements.”
3.In private hospital rooms, efforts such as staff support and programs are needed so that patients do not become withdrawn.
4.In the case of a hospital ward with multi-bed rooms, arranging space in shared space so that it becomes space where one can be alone is a major issue.
5.Concerning the application of “space hierarchy” in psychiatric hospitals, designing semi-private areas using freer forms without being restricted to clusters will be a challenge going forward. Also, the special stuff support and programs like nursing home with “space hierarchy” for elderly people should be provided.
