Quality of life and depression: symmetry concepts.
From the theory of Three-Time-dimensions based on the disturbed temporal horizon of the depressed individual: Past, Present, therapeutic-Future, new concepts of phenomenological-depression and the intrinsic-quality of life have been defined, in which both are considered as the perception of a discrepancy between, on one hand, the healthy Past and Present ill-being, and on the other, the intensity of demand for recovery or a therapeutic-Future. In order to determine the symmetry of these two concepts, the Three-Time-dimensions Synoptic Scale (3TSS) was presented to 110 subjects who had been diagnosed as suffering from major primary depression. The demonstration was carried out in three stages, the first statistical, the second mathematical, and finally, a geometrical one; it showed the importance of the temporal horizon of the depressed person in diagnosis.
