Which symptom class reflects a decreased ability to function normally in schizophrenia?

• A. Positive Symptoms in Schizophrenia
• B. Cognitive Symptoms in Schizophrenia
• C. Negative Symptoms in Schizophrenia
• D. Affective Symptoms

Answer: (C)

Negative symptoms best explain a decreased ability to function normally because they represent deficits in normal functioning itself, not additions to experience. Features like avolition (loss of motivation), alogia (reduced speech), anhedonia (reduced pleasure), and flat affect reduce daily functioning, social engagement, and motivation across work, school, and relationships. Positive symptoms (hallucinations, delusions) are extra experiences, and cognitive symptoms affect thinking processes, but the core reason for impaired everyday functioning in schizophrenia is the deficit-oriented nature of negative symptoms. Affective symptoms involve mood, which can accompany the illness but doesn’t define the functional decline as directly as negative symptoms do.
