Abstract
The time trade-off method was incorporated into a study of valuation of health states following treatment for breast cancer. A major aim of the work was to determine whether different groups give different valuations. The time trade-off technique was simple and quick to administer, acceptable to subjects, and produced different values in different groups. Age and sex of valuers had some influence: the most striking differences were found between women who had experlenced breast cancer and those who had not. The time trade-off method has considerable potential in health state valuation. The choice of valuers needs to be further explored.

This work was completed by Joy Ashby shortly before her tragic death in 1989. Incorporating the study design of the immediately preceding project, ‘Alternative Methods of Valuing Health States’ (Buxton, Ashby and O'Hanlon, 1987), valuations of breast cancer states were obtained from a group of breast cancer patients. It was decided, that despite the time lapse since the study was conducted, that this material is a valuable addition to the existing body of knowledge surrounding health state valuations.
