What defines negative symptoms of schizophrenia?

The correct answer outlines the concept of negative symptoms in schizophrenia as the absence of appropriate behaviors. Negative symptoms are characterized by a reduction or lack of abilities that are typically present in healthy individuals. These may include diminished emotional expression (such as facial expressions and eye contact), lack of motivation (avolition), social withdrawal, and a general decrease in the ability to function in daily life.

By focusing on the absence of these attributes, we can understand how they differ from positive symptoms, which involve the presence of atypical behaviors, such as hallucinations or delusions. Negative symptoms significantly contribute to the functional impairment commonly seen in individuals with schizophrenia, affecting their ability to engage socially or pursue personal goals.

This distinction is crucial in recognizing the impact of schizophrenia on daily functioning and overall quality of life, emphasizing the need for effective therapeutic interventions that target these negative aspects of the disorder.
