Reliability and validity of the Chinese version of the new fear of hypoglycemia scale: FH-15

This study aimed to evaluate the reliability and validity of the Chinese version of the Fear of Hypoglycemia scale with 15 items (FH-15). After obtaining the original author's authorization, the English version of the FH-15 scale was translated, back translated, and culturally debugged to obtain the Chinese version of FH-15. A convenient sampling method was used to extract patients with type 2 diabetes from four tertiary hospitals in Tianjin. A total of 408 patients with type 2 diabetes were investigated in the hospital to test the reliability and validity of Chinese version FH-15 scale. The content validity index of the scale was 0.92, and the content validity index of each item was 0.8–1.0. The exploratory factor analysis extracted three common factors (fear, avoidance, and interference), which contained 15 items, and the cumulative variance contribution rate was 71.245%. The confirmatory factor analysis results showed that the model fit was better at 1.981 χ2/df, GFI = 0.901, CGI = 0.962, TLI = 0.952, and RMSEA = 0.070. The cut-off value for the total hypoglycemia fear scale was 30.5. The Cronbach's α coefficient of the three dimensions of the scale was 0.918, the Cronbach's α coefficient of each dimension is 0.876–0.916, the test–retest reliability was 0.903, and the test–retest reliability of each factor was 0.733–0.930. The Chinese version of the FH-15 scale can be considered reliable and valid. The item expression is concise, clear, and easy to understand. It is suitable for clinical practice as an initial screening tool to identify and evaluate the severity of fear of hypoglycemia in patients with type 2 diabetes.
