EMPIRICAL SYNDROME GROUPINGS OF SCHIZOPHRENIC HOSPITAL ADMISSIONS.

The article focuses on empirical syndrome groupings of schizophrenia. The search for test correlates with schizophrenia is like the search for the Holy Grail; the object of the search may actually exist, but the only certain reality is in the minds of men. Conflicting proposals of relations between schizophrenia and behavior or test variables, and the failure to substantiate them upon cross-validation, usually are attributed to sample differences. Armchair speculation about types of schizophrenia has persisted with little general agreement among psychiatrists, and produced almost no worthwhile research findings.
