Comparing the prodrome of schizophrenia-spectrum psychoses and affective disorders with and without psychotic features

Our results suggest that, in the early detection of affective disorders, those that might take on a psychotic form and those with a non-psychotic course need to be considered separately. While the current at-risk criteria for psychosis function well in detecting those with a psychotic course, those with a non-psychotic course would benefit from the development and evaluation of new at-risk criteria and new early detection instruments.
