• Three schizoaffective subtypes—manic, bipolar, and depressive—were compared across multiple baseline (demographic, premorbid, morbid) and long-term outcome dimensions. Though the subtypes were comparable at baseline, the patients with depressive schizoaffective disorder scored consistently better at follow-up, although none of these differences was statistically significant. Results failed to support the validity of such subtyping in schizoaffective disorder, at least in predominantly chronic populations.
