title: Advantages of abandoning symptom-based diagnostic systems of research in schizophrenia.
abstract: An alternative is suggested to the symptom-based diagnostic conceptualizations of schizophrenia that are now general. Using a different methodological philosophy, it would investigate empirically determined underlying structure. It is proposed that studies should be more clearly directed toward linking symptoms, underlying processes, and etiology.
