Combining web-based and mail surveys improves response rates: a PBRN study from PRIME Net.

PURPOSE: The advent of Web-based survey tools has provided the investigator with an alternative to paper-based survey methods that in many instances may be less expensive to implement than traditional paper-based surveys. Newer technology, however, does not diminish the importance of obtaining an adequate response rate. METHODS: We analyzed response rate data obtained from a survey implemented across 3 practice-based research networks (PBRNs) in which the survey was first implemented electronically with 5 rounds of electronic solicitation for an Internet-based questionnaire and then by 2 rounds of a paper-based version mailed only to nonresponders. RESULTS: Overall, 24% of the total survey responses received were in the paper mode despite intense promotion of the survey in the electronic phase. CONCLUSIONS: Our results suggest there is still an important role for the use of paper-based methods in PBRN survey research. Both hard copy and electronic survey collection methods may be required to enhance clinician response rates in PBRNs.
