Schizophrenia spectrum disorders are primarily characterized by the presence of psychotic symptoms, which include delusions and hallucinations. Delusions are false beliefs that are strongly held despite contradictory evidence, and hallucinations often involve perceiving things that are not present, such as hearing voices. These symptoms are fundamental to the diagnosis and understanding of schizophrenia and related disorders.

In contrast, mood disturbances and anxiety symptoms are not the defining features of schizophrenia spectrum disorders. While individuals with these disorders may experience mood symptoms, it is the psychotic features that are central to the condition. Behavioral issues with hyperactivity might be seen in other disorders, such as ADHD, but are not characteristic of schizophrenia spectrum disorders. Lastly, personality traits and disorders pertain to long-standing patterns of behavior and inner experiences, which differ significantly from the acute psychotic experiences found in schizophrenia. Thus, the defining characteristics of schizophrenia spectrum disorders revolve around psychosis rather than mood, behavioral, or personality concerns.
