Interventional
Description of intervention(s) / exposure
The psychological status of patients assigned to the experimental group will be disclosed to the treating physicians. However, any patient diagnosed with severe psychological disorder (i.e. psychosis, severe depression) will be reported to his/her doctor irrespective of the
process of randomisation.

Study will be a randomized controlled trial examining whether disclosure of IBD patients' psychological status to
their physician influences patients' responses to the clinical treatment. IBD patients will all receive current standard
medical care. In addition, they will fill in questionnaires measuring their disease activity, quality of life and
psychological status. Participants with diagnosed psychological disorders detected by the screening instruments
(HADS, SCL90) will be randomly allocated into one of two groups. As psychological co-morbidities in patients with IBD are frequently unrecognised in
standard care settings, and often not specifically treated; this methodology should reveal whether a physician's
knowledge of the patient's mental health status influences the physician's actions or the patient's response to
clinical treatment. Study will be prospective with follow-up every 3 months for a year.

Comparator / control treatment

Outcomes
Primary outcome [1] 1292 0
The primary outcome will be remission of inflammatory bowel disease defined as 3
weeks of Crohn's disease activity < 150 points (Crohn's Disease Activity Index) or a
drop in the score of at least 70 points, and ulcerative colitis activity < 2 (Simple
Clinical Colitis Activity Index) or a drop in the score of at least 3 points.
Timepoint [1] 1292 0
Measured each 3 months for a year.
Secondary outcome [1] 2321 0
The secondary outcome will be a remission of a psychological disorder and improved quality of life. A score between 0-7 on
the Hospital Anxiety and Depression Scale (HADS) or a drop of one category will be marked as improvement of
psychological disorders. A change on SCL-90-R will confirm the result on HADS. In general, respondents who score > 11 on
either subscale of HADS have a probable psychiatric disorder (Zigmond and Snaith 1983).
The change in quality of life will be noted on the SF-12 scale.
Timepoint [1] 2321 0
The outcome will be measured each 3 months for a year.

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Patients with diagnosed psychological disorders will be allocated into two groups. The psychological status of patients assigned to the experimental group will be randomly disclosed to the treating physicians. The psychological status of patients assigned to the control group will not be disclosed to the treating physician. The psychological status of any patient diagnosed with severe psychological disorder (i.e. psychosis, severe depression) will be reported to his/her doctor irrespective of which experimental group the subject is assigned to. The treatment approach will be at the physicians discretion.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Random number tables will be used to generate a randomisation schedule. Allocation to study group will be via a preorganised sequence of sealed envelopes each containing the questionnaires for the next follow-up.
