What criteria should be met by a potential marker for vulnerability to schizophrenia?
Answer:
A potential marker for vulnerability to schizophrenia should distinguish between persons who have schizophrenia and those who do not. The marker should be a stable characteristic over time. The proposed measure of vulnerability should identify more people among the biological relatives of schizophrenic patients than among people in the general population. The proposed measure of vulnerability should be able to predict the future development of schizophrenia among those who have not yet experienced psychotic episodes.
