US Military Service Members' Reasons for Deciding to Participate in Health Research.

Abstract

Researchers have reported challenges in recruiting US military service members as research participants. We explored their reasons for participating. Eighteen US military service members who had participated in at least one health-related research study within the previous 3 years completed semi-structured individual interviews in person or by telephone, focused on the service members' past decisions regarding research participation. Service members described participation decisions for 34 individual research experiences in 27 separate studies. Service members' reasons for participation in research clustered in three themes: others-, self-, and fit-focused. Each decision included reasons characterized by at least two themes. Reasons from all three themes were apparent in two-thirds of individual participation decisions. Reasons described by at least half of the service members included a desire to make things better for others, to improve an organization, to help researchers, and to improve one's health; understanding how they fit in studies; and convenience of participation. Findings may help researchers, study sponsors, ethicists, military leaders, and military decision-makers better understand service members' reasons for participating in research and improve future recruitment of service members in health research. © 2017 Wiley Periodicals, Inc.
