Hypothesis
Does administering smartphone surveys every 2 weeks improve response rates compared to every 4 weeks among older adults?
Conclusion
The study found that more frequent survey deployment improved response rates among older adults over time.
Supporting Evidence
- The response rates decreased over time in both groups, but less so in the experimental group.
- The mean outcome decreased from 85% to 66% in the experimental group.
- The mean outcome decreased from 85% to 59% in the control group.
- The difference in response rates between the two groups increased over time.
Takeaway
Older adults are more likely to respond to surveys if they get them every two weeks instead of every four weeks.
Methodology
A randomized controlled trial comparing two survey deployment frequencies over 32 weeks.
