Health State Trade-off Survey across 5 countries
We undertook a Health State TTO survey among the general population in France, Italy, Brazil, Spain and Australia.
We recruited respondents via in-street intercepts or consumer databases and invited them to a central location to take part in the health state exercise.
All interviewers received thorough training so that they could guide respondents through the interview process as the Time Trade Off Experiment methodology is a little tricky for both interviewers and respondents to understand conceptually.
Interviews were completed in a timely manner and to a very high percentage success rate.
