The variety of studies reported in this monograph originated with the purpose of assessing the effects of drugs on hospitalized psychotics. Later the goal was vastly enlarged to establishing an objective taxonomy for the so-called behavior disorders through the isolation of major psychotic syndromes and types. The authors present evidence for ten statistically derived psychiatric syndromes, six psychotic types or classes, and two theoretical models for the organization of the syndromes.
