Moderating effect for illness uncertainty on the relationship of depressive and anxiety symptoms among patients with type 1 diabetes in Taif region, Saudi Arabia.

Background: Illness uncertainty was found to be associated with the development of depressive and anxiety symptoms among patients with type 1 diabetes and chronic illness in general. However, the moderating effect of illness uncertainty was not examined in sufficient depth. The current study evaluates how the path from diabetes distress to depression and anxiety is mediated by illness uncertainty, ambiguity, symptoms and course predictability, and illness complexity.
