Risk perception, self-efficacy, trust for physician, depression, and behavior modification in diabetic patients.

We evaluated the associations of risk perception, self-efficacy, and trust with two health promotion behaviors (food habits and exercise) and depressive mood. Diabetic patients aged between 40 and 64 ( = 1195) were included in the analyses. Risk perception worsened behavioral changes in terms of food habits and depression, whereas self-efficacy and trust improved food habits, exercise, and depression; trust improved exercise and depression.
