Materials and Methods: This is a cross-sectional investigation in which the target population includes 94 patients with IBD, who had medical care files in Imam Reza Hospital and Tabriz Golgasht Specialized Clinic. A 19-question inventory is the tool for data collection that its validity was approve by 10 experts and its reliability was examined and verified by conducting a pilot study and with calculation of internal consistency (α = 0.78). SPSS software was employed to analyze data. Results: The mean score of the variable of CQ was derived (70.63 ± 9.67) in patients with IBD disease. All participants had acquired the scores of self-management at the first phase. However, at last 11.7% of them had reported the highest scores in variable of CQ and they could continue their own medical care trend under variable conditions like stress and financial problems. Similarly, there was a significant relationship among CQ with an educational degree in the participants (P = 0.050) so that as the educational level was higher, the score of CQ was also increased. Conclusion: The acquired results signify that CQ is relatively acceptable in the studied population but major problems are visible in some areas, and this may imply the necessity for consideration by healthcare directors.
