Only when psychotic states persist in a sustained fashion for two weeks or longer without concurrent affective symptoms is the diagnosis schizoaffective disorder, schizophreniform disorder or schizophrenia.The second cardinal guideline in the DSM-5 diagnosis of schizoaffective disorder is one of timeframe. DSM-5 requires two episodes of psychosis (whereas DSM-IV needed only one) to qualify for the schizoaffective disorder diagnosis. As such, it is no longer an "episode diagnosis." The new schizoaffective framework looks at the time from "the [first episode of] psychosis up to the current episode [of psychosis], rather than only defining a single episode with [co-occurring] psychotic and mood syndromes." Specifically, one of the episodes of psychosis must last a minimum of two weeks without mood disorder symptoms, but the person may be mildly to moderately depressed while psychotic. The other period of psychosis "requires the overlap of mood [disorder] symptoms with psychotic symptoms to be conspicuous" and last for a greater portion of the disorder.These two changes are intended by the DSM-5 workgroup to accomplish two goals:
Increase the diagnosis consistency (or reliability) when it is used;
Significantly decrease the overall use of the schizoaffective disorder diagnosis.If the schizoaffective diagnosis is used less often, other diagnoses (like psychotic mood disorders and schizophrenia) are likely to be used more often; but this is hypothetical until real-world data arrive.
