Adherence, body mass index, and depression in adults with type 2 diabetes: The mediational role of diabetes symptoms and self-efficacy.

Abstract

Results provide evidence consistent with two independent pathways by which BMI and adherence could increase depression in people with Type 2 diabetes. The first pathway indicates that the effects of higher BMI and poor adherence on depression are mediated by lower self-efficacy perceptions. The second pathway indicates that the effect of higher BMI on depression is mediated by increased diabetes symptoms.
