Background. We explore the nature and aspects of the information needs of informal carers. A comprehensive understanding of these needs is important because it is the first step to meeting these needs effectively. Aim. We report on an empirical validation of a framework for understanding the information needs of carers, composed of four need states: recognised-demanded, recognised-undemanded, unrecognised-demanded, and unrecognised-undemanded. Methods. A qualitative study employed semi-structured interviews with nine informal carers of diabetic children.
