Helping individuals with diabetes to control their blood sugars through self-management is an important goal, and counting carbohydrates (CHO) remains a key part of diabetes education and management. There is very little research examining CHO counting education with adolescents who have type 1 diabetes (T1DM). The purpose of this pilot study is to evaluate a newly developed internet-based teaching module of CHO counting for adolescents, ages 12-17 years, with T1DM and who do not regularly CHO count and require instruction. A secondary aim is to assess feasibility for a future, larger-scale clinical trail. An effective web-based CHO counting tutorial could be used to strengthen current diabetes education programs and may serve as a basis for developing other teaching modules. Advantages of web-based teaching include convenience, increased accessibility, and the ability to review and reinforce teaching concepts through repetition. It may also encourage adolescents to take the initiative for their own diabetes care, beginning with a self-directed, active learning experience.
