Research strategy for health sciences: Facebook friend request is non-differentially accepted in a diverse, young adult population.

Social media is being used for recruitment and the study of health-care choices and behavior, and could be particularly helpful to reach young adult populations outside of a 4 year college setting. The aim of this study was to report on overall success of recruiting young adults in diverse settings with respect to education and employment into a study using Facebook (FB). Young adults (n = 380, 50% male, 44% white) who had been involved in a longitudinal research project received a friend request from the research study group's profile. Acceptance rates of friend requests and sociodemographic and mental health factors associated with acceptance were evaluated. Approximately 67% of 318 participants who received a friend request accepted the request. Sociodemographic and mental health characteristics were similar between those who did and did not accept friend requests, suggesting non-differential recruitment through FB. Friending through FB is a feasible way to reach young adults involved in health and behavioral research, and could be a way to expand the populations that are studied in health science research to maximize generalizability of the conclusions drawn.
