Mood disorders with psychotic features are distinguished from schizoaffective disorder by which pattern of psychotic symptoms?

• A. Psychotic symptoms occur only during mood episodes
• B. Psychotic symptoms persist outside mood episodes
• C. Mood symptoms are absent
• D. Onset in childhood

Answer: (A)

The key idea is when psychosis occurs relative to mood symptoms. In mood disorders with psychotic features, psychotic symptoms appear only during mood episodes and disappear when the mood disturbance subsides. In contrast, schizoaffective disorder features psychosis that can occur outside mood episodes, with mood symptoms present for a substantial portion of the illness and a period of psychosis without mood symptoms. So the pattern that distinguishes mood disorders with psychotic features from schizoaffective disorder is that psychotic symptoms occur only during mood episodes. The other options don’t fit: psychosis persisting outside mood episodes would align more with schizoaffective or schizophrenia; mood symptoms being absent isn’t characteristic of mood disorders with psychotic features; onset in childhood is not diagnostic.
