F40 vs F41

Both involve significant anxiety symptoms that can include physical sensations such as a racing heart, sweating, and a sense of dread.

• F40's anxiety is reliably triggered by a specific, identifiable situation or object and is reduced or absent when the trigger is avoided.
• F41's anxiety (panic disorder or generalized anxiety disorder) is not reliably bound to one specific situation — it occurs unpredictably (panic disorder) or persists across many unrelated domains (generalized anxiety disorder).
• A vignette's description of when and where the anxiety occurs — reliably in one specific context, or unpredictably/pervasively across contexts — is the decisive fact.

What weakens F40: Evidence that anxiety occurs unpredictably across unrelated settings weakens F40 and favours F41; evidence that anxiety is reliably tied to one specific, identifiable trigger weakens F41 and favours F40.

Neither boundary is primarily about duration; the decisive factor is whether the anxiety is situationally bound (F40) or not (F41).

A vignette's account of the trigger pattern — one specific, identifiable situation versus multiple or no clear trigger — is what should be checked, not simply the intensity of the anxiety.

Whether the anxiety reliably occurs in one specific, identifiable situation and is reduced when that situation is avoided, or occurs unpredictably or pervasively across many contexts.

Classifying by the intensity or physical symptoms of the anxiety alone, without checking whether it is bound to a specific situational trigger.
