Abstract：Objective To establish the Minimum Clinically Important Difference(MCID)for PROISCD-GM(V1.0)in patients with chronic gastritis.Methods Two cross-sectional surveys were conducted using PROISCD-GM(V1.0)and SF-36 before and after treatment.The MCID for each domain and the total score of the questionnaire were calculated using the anchor and distribution methods.The final MCID was obtained by combining the results from both methods.Results The difference in scores before and after treatment with PROISCD-GM(V1.0)for chronic gastritis was statistically significant(P＜0.001).The MCID for the dimensions of physical health,mental health,social health,spiritual/religious health,and the total score were 9.52,9.01,6.25,8.33,and 8.21 points,respectively.Conclusion When the score exceeds the MCID,it can be considered that the intervention measures have practical clinical signifi-cance.The established MCID can provide a basis for relevant clinical decisions and efficacy evaluation in the management of chronic gastritis.
