Summary
Face-to-face time trade-off (TTO) interviews can be challenging. Digital TTO interviews offer flexibility and cost savings, with largely similar results, though rapport and visual cues may be affected.
Area of Science:
- Health Economics
- Health Services Research
- Patient-Reported Outcomes
Background:
- Time trade-off (TTO) interviews are standard for large-scale health valuation studies.
- Personal TTO interviews face logistical challenges like travel and scheduling.
Purpose of the Study:
- To guide researchers on conducting digital TTO (tele-TTO) interviews.
- To discuss the advantages and disadvantages of tele-TTO compared to personal TTO.
Main Methods:
- The study guided researchers on tele-TTO implementation.
- A project compared personal TTO and tele-TTO interviews.
Main Results:
- Tele-TTO reduces travel needs and increases scheduling flexibility, potentially lowering costs and improving sampling.
- Potential disadvantages include reduced visual cues, rapport challenges, and selection effects.
- Tele-TTO interviews are feasible, offer interviewer flexibility, and yield comparable results to personal TTO.
Conclusions:
- Tele-TTO is a viable alternative to personal TTO, especially when logistical constraints exist.
- Further research is needed on selection effects and participant experiences with tele-TTO.
