The Course of Juvenile Schizoaffective and Schizophrenic Psychoses: The Use of Pattern Analysis for Classifying the Development of Schizophrenia-Like Illnesses
The use of current research methods for the study and analysis of records deriving from longitudinal studies of patients’ illnesses gives rise to a number of problems for which there are no simple satisfactory solutions. In the process of diagnosis one is faced with a range of events and symptoms that appear during the course of the illness. The methods used to construct different classes of symptoms from separable events during the course of the illness result sometimes in precise and at other times in rather crude descriptions. In part, precision depends on the degree to which the particular diagnostic criteria used can differentiate between features of the illness. In part, the separability of periods of illness depends on the duration of the symptoms, that can themselves vary during the period.
