39.6 (13.2)
40.1 (12.3)
207 Education programme covering both medical and psychological aspects
Medical sessions: held by physician specialists providing information on IBD (e.g. anatomy, epidemiology, clinical aspects, diagnosis and therapy)
Psychological sessions: held by psychologists using patient-centred approach, with participants being encouraged to exchange experiences, ask questions and present individual coping strategies and self-management skills
IBD referral centres/group-based, 1 weekend, 15 participants per batch (16 batches),
medical modules lasted 8 h, psychological modules 3.5 h

43.4 (11.0) 540 Education programme covering medical and psychological modules
Medical modules: delivered to large open groups in lecture format by gastroenterologists, providing information on IBD (e.g. anatomy, diagnostic, treatment options). Patients had time to ask questions
Psychological modules: delivered in small, closed groups by psychologists using patient-centred approach designed to encourage participants to share their personal experiences about how to best cope with the disease. Patients discussed ways of coping with feelings of anxiety and role-played self-confident communicative behaviour in common difficult social situations
