[The distinctive quality of depressed mood. VI. The neuroses as mood disorders (a controlled study of the López Ibor hypothesis)].

The authors research the characteristics of sadness in neurotic, depressed patients and in subjects with depressive reactions, using the Pathological Sadness Index. They research an aspect of the López Ibor's hypotheses about the neurosis as diseases of the mood. The neurotic patients suffer from a sadness with pathological characteristics, as depressed subjects, instead of the normal sadness suffered by people with reactions.
