Cultural adjustment and revision of the translated questionnaire were conducted through Delphi method and pre-survey method to form GDMQ-34. From January to May 2020, the questionnaire was used to conduct quality of life survey on 220 patients with gestational diabetes mellitus (GDM) in the Obstetrics Department of four ClassⅢ Grade A hospitals in Qingdao to evaluate its reliability and validity.Results:A total of 220 questionnaires were issued and 203 were effectively returned, with an effective recovery rate of 92.3%. The Chinese version of GDMQ-34 had 34 items, including 6 dimensions of pregnancy worry, behavioral restraint, physical symptoms, psychological symptoms, medications and social support. The total Cronbach's α coefficient of the Chinese version of GDMQ-34 was 0.772, and the test-retest reliability was 0.820, and the Cronbach's α coefficients of each dimension were 0.855, 0.902, 0.868, 0.880, 0.896 and 0.880 respectively. The content validity index at the average scale level of the questionnaire was 0.982, and the content validity index at the item level was from 0.867 to 1.000. The exploratory factor analysis extracted 7 common factors, and the cumulative variance contribution rate was 68.591%.Conclusions:The Chinese version of GDMQ-34 has good reliability and validity, and it is scientific and practical, and can be used as a simple tool for evaluating the quality of life of patients with GDM.
