The purpose of this study was to assess the effectiveness of a dietary support program for patients with Crohn disease based on behavior analysis and designed to maintain remission and improve satisfaction with meals. The core of the program consisted of self-monitoring by patients and evaluation by a healthcare professional. The 32-week program consisted of a 4-week baseline period, 20-week intervention period, and 8-week follow-up period. Participants filled out questionnaires measuring outcomes every 4 weeks, for a total of nine questionnaires per patient. Of the 13 patients who started the program, 11 completed the study. Of these, nine showed increased frequency of testing foods during the intervention period, with seven maintaining testing during the follow-up period. No patient experienced a worsening of health conditions. Of the 11 patients who completed the program, seven reported increased satisfaction with meals. In conclusion, this program helped increase the frequency of testing foods in patients with Crohn disease, while maintaining health conditions and improving satisfaction with meals.
