Primary Objective:
The primary objective of the study is to identify and delineate effective recruitment practises in a large, multi-site, longitudinal, observational study employing both military service members and Veterans.
Setting:
Four Chronic Effects of Neurotrauma Consortium sites.
Design:
A descriptive study.
Results:
Overall and cohort-specific recruitment increased with the addition of focused recruitment strategies and a military/Veteran-centric recruitment director.
Conclusion:
Use of site-specific strategies aligned with local Institutional Review Board procedures and emphasizing awareness of service member organizational allegiances was the key to effective recruiting. Adding a recruitment director with background similar to study participants coincided with significantly improved overall participant numbers and specific subpopulations of research subjects, thus adding to the value of the study.
