The Time Trade-Off Theory

The Time Trade-Off (TTO) Theory is a method used in health economics to measure how people value different health states. It works by asking individuals to choose between living a longer time in a less desirable health condition or a shorter time in perfect health. By adjusting the lengths, it helps determine how much someone is willing to give up in quality or length of life to avoid a particular health state. This approach provides insight into the perceived burden of health conditions and aids in evaluating healthcare interventions’ value from the patient’s perspective.
