The field of psychiatry has begun to question its assumptions and analyze its data in order to merge closer with evidence-based medicine. The removal of the "episode diagnosis," and the addition of two episodes of psychosis, as qualifications for the DSM-5 schizoaffective diagnosis, may improve the diagnosis' consistency over DSM-IV for research purposes, where diagnostic criteria are by necessity followed "exactingly". But the new definition remains long, unwieldy, and perhaps still not very useful for community clinicians—with two psychoses, one for two weeks minimum and without mood disorder (but the person can be mildly or moderately depressed) and the other with significant mood disorder and psychosis lasting for most of the time, and with lasting mood symptoms for most of the residual portion of the illness. Community clinicians used the previous definition "for about a third of cases with non-affective psychotic disorders." Non-affective psychotic disorders are, by definition, not schizoaffective disorder. For clinicians to make such sizeable errors of misdiagnosis may imply systemic problems with the schizoaffective disorder diagnosis itself. Already, at least one expert believes the new schizoaffective definition hasn't gone far enough to solve the previous definition's problems.
