Evaluates two methods for facilitating task-comprehension in generic preference assessment instruments. It uses visual representations of the desired health state to provide information and a paired comparison task to measure preferences. Information about people's relative preferences for health care outcomes is usually obtained using questionnaires that ask subjects to imagine health states of various kinds. Use of the figures in this study did not change rating variance, and the paired comparisons were reliable compared with the direct rating tasks and also reduced the number of counter-intuitive ratings.
