Hypothesis
Subjects receiving increased attention via a randomly selected education program or physical examination session would have higher follow-up rates than those receiving less attention.
Conclusion
The overall web-based response rate during the first year of the POLM trial was lower than expected for standard clinical trials, and was significantly associated with demographic characteristics, health status, and individualized attention.
Supporting Evidence
- Responders were more likely to be older, Caucasian, and have higher education and income.
- Response rates were significantly associated with individualized attention from physical examinations.
- Smoking status was a significant predictor of response rates.
Takeaway
This study looked at why some soldiers responded to online surveys about back pain while others didn't, finding that older soldiers and those who got more personal attention were more likely to respond.
Methodology
Soldiers were cluster randomized into different exercise programs and followed up with web-based surveys to assess response rates.
Potential Biases
Potential attrition bias due to low follow-up rates and the homogeneity of the sample.
Limitations
The study's findings may not be generalizable due to the homogeneity of the military population and potential biases in self-reported data.
Participant Demographics
71% male, 72% White/Caucasian, mean age 22.0 years.
