Table. UK Royal College of Physicians ‘3 Questions’ screening tool

In the last month: Yes No
Have you had difficulty sleeping because of your asthma symptoms (including cough)?
Have you had your usual asthma symptoms during the day (cough, wheeze, chest tightness or breathlessness)?
Has your asthma interfered with your usual activities (e.g. housework, work/school etc)?


No to all three questions indicates good control.

Yes to 2 or 3 questions indicates poor control.

Yes to 1 question indicates that more detailed questioning is needed to assess level of asthma control (using another validated questionnaire or by asking about frequency of daytime symptoms, reliever requirement, limitation of activities and symptoms at night or on waking during the previous month).

Note: This test provides a quick and easy way of confirming someone’s asthma control is good, or identifying those who need more assessments.
