Theory of Unpleasant Symptoms

A nursing theory conceived by E. R. Lenz proposing that patients perceive illnesses and challenging treatments as clusters of noxious symptoms that both individually and jointly impact their experience of illness, their emotional distress, and their functional abilities. As illness and treatment progress, symptoms change and have varying impacts on each other and on the patient's quality of life.
