Abstract: In order to develop and standardize a diabetic patient sports hindrance survey tool, and to clarify major sports hindrances suffered by type 2 diabetic patients in China, the authors applied the world latest educational/psychological measurement technology to simplify the survey tool, so that it can be applied to mass groups of people better. The authors carried out a questionnaire survey on 197 type 2 diabetic patients (104 males, 93 females, average age: 53.6). The survey tool originated from a mature sports hindrance survey questionnaire established in the United States, including 43 sports hindrances, used to determine the degree of hindrance in their sports participation. The authors analyzed the data by apply-ing the Rasch model, determined the magnitudes of sports hindrances based on their Logits values, and then analyzed the results according to the Rasch model, reduced questionnaire contents on the basis of maintaining the original content structure, screened out the best reduced questionnaire version by means of correlation analysis, and found that the lack of sports knowledge and the lack of professional guidance were major sports hindrances for type 2 diabetic patients in China. Based on their analysis by applying the new item response theory (IRT) model, the authors found that all the 4 reduced versions of questionnaires were correlative to the original 43-hindrance version, and that the 16-hindrance questionnaire tool had the highest efficiency, whose usage was recommended.
