Schizoaffective disorder criterion: Requires that a major mood episode be present for what portion of the disorder's total duration?

• A. For a minority of the disorder's duration
• B. For a majority of the disorder's total duration
• C. For all of the disorder's duration
• D. For none of the duration

Answer: (B)

In schizoaffective disorder, mood symptoms must be present for a substantial portion of the illness. Specifically, the major mood episode (depression or mania) needs to occupy more than half of the total duration of the disorder. This helps distinguish schizoaffective disorder from pure schizophrenia or a mood disorder with psychotic features. It’s also important that there are periods of psychotic symptoms (delusions or hallucinations) without mood symptoms for at least a brief time (typically at least two weeks) to meet the criteria. That separation is what differentiates schizoaffective disorder from someone who has a mood disorder with psychotic features. So the best fit is that mood symptoms must be present for the majority of the illness’s total duration.
