Positive and negative a priori symptom scales were operationalized with the BPRS and the NOSIE. Acutely and consecutively admitted psychiatric patients ( N = 247) were rated with these scales. Research questions dealt with the psychometric properties of the scales. It was found that the positive symptom scales had sufficient internal consistency; the negative scales did not. Diagnostic groups could be distinguished better with the positive symptom (PS) than with the negative symptom (NS) scales. The outcome of this research suggests that the positive and negative symptoms distinction is less meaningful in cross‐sectional research, in which acute patients are rated, than in longitudinal research.
