Theories of Uncertainty in Illness

The original uncertainty in illness theory (UIT) was developed to address uncertainty during the diagnostic and treatment phases of an illness or an illness with a determined downward trajectory. The reconceptualized uncertainty in illness theory (RUIT) was developed to address the experience of living with continuous uncertainty in either a chronic illness requiring ongoing management or an illness with a possibility of recurrence. The finding that uncertainty was reported to be common among people experiencing illness or receiving medical treatment led to the creation of the UIT. Beginning with the publication of the Uncertainty in Illness Scale, there has been extensive research into uncertainty in both acute and chronic illnesses. Studies that focus on the health care or home environment for treatment of illness fit under the stimuli frame component of event familiarity. The clinical literature supports delivery of information as the major method to help patients manage uncertainty.
