Background: Non-adherence to drug therapy is common in Inflammatory Bowel Disease (IBD). Patients' beliefs about treatment have an important influence on adherence. An in-depth understanding of this area is, therefore, important for patient-centred care. The aim of the study was to assess patients' perspectives and beliefs about their medication and to determine how this relates to medicine taking and other related health behaviour as part of a larger qualitative study on health care related behaviour in patients with IBD.
