The Inflammatory Bowel Disease Questionnaire (IBDQ) is a self-administered instrument for determining the health status of a patient with inflammatory bowel disease. There are 32 questions which are used to derive 4 subscores covering various aspects of the person's life. The questionnaire was developed at McMaster University in Canada.


Groupings of the 32 questions:

(1) bowel symptoms (10)

(2) systemic symptoms (5)

(3) emotional function (12)

(4) social function (5)


Responses are graded using a Likert scale ranging from 1 (worst imaginable) to 7 (normal).



• minimum score: 32

• maximum score: 224

• The higher the score, the better the patient's functional status.



• Use of the instrument requires a fee-based agreement with McMaster University.
