Which criteria have no requirement for functional deterioration?

• A. DSM-5-TR criteria
• B. DSM-5 criteria
• C. ICD-11 criteria
• D. DSM-4 criteria

Answer: (C)

Focus on how different diagnostic systems treat functional deterioration. In DSM-5 and DSM-5-TR, a diagnosis typically requires that the symptoms cause clinically significant distress or impairment in social, occupational, or other important areas of functioning. That means the person’s difficulties must translate into real-world impairment to meet the disorder criteria.

ICD-11, on the other hand, often centers on the presence of core symptoms and their duration without mandating impairment as a universal criterion. You can meet an ICD-11 diagnostic threshold based on the symptom pattern itself, even if the person’s daily functioning isn’t markedly deteriorated. This is why ICD-11 criteria are considered to have no strict requirement for functional deterioration in many categories.

So, ICD-11 criteria are the ones that don’t universally require impairment, which is why they’re identified as the correct option for this question.
