Which diagnostic criteria specify no requirement for functional deterioration?

• A. DSM-5-TR diagnostic criteria
• B. DSM-5-TR specifiers
• C. RDoC framework
• D. ICD-11 criteria

Answer: (D)

ICD-11 takes a symptom- and duration-based approach for schizophrenia, without requiring a clear decline in functioning. The diagnosis rests on the presence of core psychotic symptoms (such as delusions, hallucinations, disorganized speech or behavior, and negative symptoms) for a sufficient period, and exclusion of other explanations. This means a person could meet ICD-11 criteria even if their daily functioning isn’t visibly deteriorated. In contrast, DSM-5-TR criteria require that the disturbance causes clinically significant distress or impairment in social, occupational, or other important areas of functioning. DSM-5-TR specifiers describe additional features but don’t remove that impairment requirement. The RDoC framework isn’t a diagnostic criterion at all. So ICD-11 specifies no requirement for functional deterioration.
