We sought to discover adolescents' thoughts about participation in longitudinal research and identify recruitment and retention strategies that were meaningful to them. We conducted seven focus groups with 10-15-year-olds in two large rural centers in New South Wales, Australia, and all focus groups were digitally recorded, transcribed, and analyzed. Adolescents discussed factors salient to their involvement in focus groups, as well as factors that may influence involvement in a longitudinal study. At the outset of the focus groups, adolescents had a positive view of "research," but were reluctant to engage in research that involved biologic samples. Effective recruitment of adolescents requires an appreciation of motivators, and time and resources to extend potential participants' understanding.
