The questionnaires were tested for content and face validity, readability, responsiveness and reliability. Convergent validity was assessed by correlating the U\u2010IBDQ score with physician's subjective assessment scores. Discriminant validity was assessed by comparison to healthy controls (HC), patients with chronic gastrointestinal (GI) conditions other than IBD, and to GI nurses. Multivariate analysis was performed to determine factors associated with a high level of disease understanding.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      The study population consisted of IBD patients (\n                      <jats:italic>n<\/jats:italic>\n                      \u00a0=\u00a0106), HC (\n                      <jats:italic>n<\/jats:italic>\n                      \u00a0=\u00a035), chronic GI disease patients (\n                      <jats:italic>n<\/jats:italic>\n                      \u00a0=\u00a038) and GI nurses (\n                      <jats:italic>n<\/jats:italic>\n                      \u00a0=\u00a019).
