Domains of impairment in schizophrenia spectrum
What are the five major domains of impairment in schizophrenia spectrum and other psychotic disorders?
- 1. Perception (hallucinations—perceptions without stimuli)
- 2. Belief (delusions—fixed false beliefs despite conflicting evidence)
- 3. Thought (disorganized thinking/speech; e.g., loosening of associations, derailment)
- 4. Motor (disorganized motor behavior; e.g., catatonic behavior)
- 5. Emotion (negative symptoms; e.g., flattened affect, alogia, avolition, anhedonia, asociality)
The assessment of each of these domains, as well as cognition, mood (depression or mania), and historical elements (onset and time course) are critical in differentiating the psychotic disorders from medical condition- and substance-induced psychoses
