FoH, fear of hypoglycemia. Items with factor loadings below 0.3 were not shown (Item: I make sure I have someone with me when I go out to avoid having a low blood sugar; Item: I eat a lot more often than I really need to avoid having a low blood sugar). All items were rated on a 5-point scale (1 – Strongly Disagree to 5 – Strongly Agree); Item scores were summed to produce worry and behavior subscale scores, and a total score. Higher scores indicate greater FoH.
