Important relation between self-efficacy, sense of coherence, illness perceptions, depression and anxiety in patients with inflammatory bowel disease.

Anxiety and depression are common disturbances in patients with inflammatory bowel diseases (IBD), and were found to impact the disease course. Illness perceptions (IPs), self-efficacy (SE) and sense of coherence (SOC) are important psychological functions, used by the individual to cope with his chronic disease. to investigate the association of IP, SE and SOC on anxiety and depression among patients with IBD. Patients filled questionnaires including: demographic, socioeconomic and clinical features. Depression and anxiety were assessed using the Hospital Anxiety and Depression Scale. IP, SE and SOC were assessed using the Brief Illness perception Questionnaire, IBD-SE and SOC scales. The study sample consisted of 299 patients with IBD, median age 34.15, 63% females, 70.9% had Crohn's disease, filled the questionnaires. In the multivariate analysis, lower results in IP, SE and SOC were found to be associated with significantly increase anxiety (OR 8.35, p<0.001; OR 4.18, p=0.001; OR 4.67, p<0.001, respectively) and depression (OR 15.8, p=0.001; OR 10.99, p=0.029; OR 6.12, p=0.014. Anxiety and depression are associated with IP, SE and SOC in patients with IBD. Clinicians should be aware of this impact, recognise their patients' psychological abilities to cope with the disease and improve those abilities, when needed, in order to achieve a better coping with the disease and to prevent the development of anxiety and depression.
