Abstract: Objective: To translate the Diabetes Fear of Injecting and Self-testing Questionnaire (D-FISQ) into Chinese, and to test its reliability and validity in children with Type 1 Diabetes Mellitus. Methods: The Chinese version of the D-FISQ was developed by using Brislin translation model including translation, back translation and cross-cultural adaptation. A total of 196 children with Type 1 Diabetes Mellitus were recruited by a convenience sampling to evaluate the reliability and validity of the scale. Results: The Chinese version of D-FISQ contains the Fear of Self-Testing (FST) and Fear of Insulin Injecting (FSI) scales, and the exploratory factor analysis of both subscales extracted 4 common factors, the cumulative variance contribution of FST was 61.769% and that of FSI was 62.812%. The Cronbach's α coefficient for total scale was 0.911 and the content validity index was 0.96. The Cronbach's α coefficient for FST subscale was 0.802 and the test-retest reliability was 0.831. The Cronbach's α coefficient for FSI was 0.833 and the test-retest reliability was 0.833. Conclusion: The Chinese version of the D-FISQ has good reliability and validity and can be used as a tool to assess the fear of insulin injecting and self-testing in children with Type 1 Diabetes Mellitus.
