Diabetic patients with lower literacy or numeracy skills are at greater risk for poor diabetes outcomes. This study evaluated the impact of providing literacy- and numeracy-sensitive diabetes care within an enhanced diabetes care program on A1C and other diabetes outcomes. In two randomized controlled trials, we enrolled 198 adult diabetic patients...
Article
Portion-size estimation is an important component of weight management. Literacy and numeracy skills may be important for accurate portion-size estimation. It was hypothesized that low literacy and numeracy would be associated with decreased accuracy in portion estimation. A cross-sectional study of primary care patients was performed from July 200...

Large prospective trials have shown that maintaining glycated hemoglobin less than 7% greatly reduces complications but translating this level of control into everyday clinical practice can be difficult. Intensive improvement programs are successful in attaining control in pati...
Article
Self-efficacy is often studied as a predictor of professional practice behaviors or as an outcome of clinical training, using brief scales with little validation. This study examines the utility of a brief self-efficacy scale in the evaluation of a clinical training program. Subjects were 119 registered dietitians who participated in diabetes train...
Article
A 2-week summer school program, combining problem-based learning with behavior therapy, was developed to help adolescents with insulin-dependent diabetes improve their ability to cope with obstacles to dietary management. Ten students participated in a first session, and 9 participated in a second session, serving as a waiting list control group. O...
