The AQoL team developed, used and validated an online version of a Time Trade Off (TTO) interview.
This is how you can implement it:
- Use the opensource survey system Limesurvey to host the questionnaire. (Our installation is hosted on a secure Monash server.)
Please contact Jason Cleeland for further information about using Limesurvey.
- The voiceovers and avatars were developed using Sitepal.
- The avatar videos were hosted on Vimeo.
- The TTO was set-up with a decision tree that abided by logic rules to decide which year choice to display next.
- The script and images for the system are presented in this powerpoint.
