Psychopathometry and homogenous syndrome dynamics.

The principle of homogeneous dynamic of syndromes means that diminishing of single psychic functions or the severeness of syndromes is correlated to the total syndrome. The validity of this principle was alleged for reversible physically founded psychoses and for cyclothymic depressions. Various empirical investigations confirm the validity of the principle of homogeneous dynamic of syndromes. These findings suggest practical benefit for the development of psychopathometric procedures: constructions of short tests. Perhaps the range of validity of the principle of homogeneous dynamic of syndromes may be extended on cyclothymic mania, too. Empirical investigations will prove this question.
