Pain and functional impairment as mediators of the link between medical symptoms and depression in type 2 diabetes.

Background: Among people with diabetes, depression is more common and is associated with greater morbidity and mortality. A better understanding of mechanisms underlying the link between poor health and depression is needed. Pain and functional impairment may account for the effect of poor health on depression in diabetes.

Educational attainment moderates the effect of a brief diabetes self-care intervention.

Aims: Those with less education are at increased risk for developing diabetes and have a poorer prognosis. Intensive diabetes self-care interventions have been more effective at improving glycemic control in those with lower educational attainment. Due to limited resources, the focus has shifted to brief, cost-effective health interventions.

Depression and hemoglobin A1c in type 1 and type 2 diabetes: the role of self-efficacy.

Aims: To examine a self-efficacy explanation of the finding that depression is related to hemoglobin A1c (A1c) level in people with type 1 but not type 2 diabetes.

Methods: Cross-sectional design involving 124 participants with type 1 (n=32) and type 2 (n=92) diabetes. Participants completed measures of depression and diabetes-related self-efficacy.
