Background
Conscientiousness is a personality trait characterised by the ability to control impulses, delay gratification, set and reach goals, and plan in advance. Conscientious people are more likely to be non-smokers, do physical activity and practice healthy eating behaviours. They are also more likely to be adherent to medication. The aim of this study was to assess whether people with Crohn’s disease who score high on conscientiousness are more likely to be adherent to enteral nutrition (EN) therapy than low scorers.
Methods
Adults aged 16 to 40 years with newly diagnosed Crohn’s disease or having a flare of disease were invited by their gastroenterologist to use nutrition therapy to induce disease remission. Nutrition therapy was either eight weeks of exclusive enteral nutrition (EN) or two weeks of exclusive EN followed by six weeks of partial EN and one meal per day. A convenience control group of healthy participants with no history of gastrointestinal symptoms was also recruited to use exclusive EN for two weeks. Adherence to EN was self-reported fortnightly using a standardised questionnaire. Non-adherence was defined as patients who repeatedly ate foods while using EN or ate more than one meal per day on partial EN. Patients who could not initiate or did not tolerate the EN formula were included in the non-adherent group. Prior to starting nutrition therapy, conscientiousness was measured using the well-validated conscientiousness subset of the Big Five Inventory.
Results
Twenty-three (59%) of the 39 patients recruited with Crohn’s disease completed and adhered to the eight-week treatment. Reasons for non-adherence by the 14 patients who did not complete treatment included: could not initiate EN (
Conclusion
Conscientiousness was associated with adherence to EN therapy. EN therapy can be a cognitively and emotionally demanding treatment and this personality trait should ideally be considered when determining suitable candidates for EN therapy.
