A secondary objective was to inform future measurement of identified factors. A sample of 20 intercollegiate athletes participated in an open-ended survey, followed by a corresponding focus groups (≈90-minute). Qualitative data were gathered relative to the factors impacting athletes’ excessive alcohol intake, fruit and vegetable consumption (FVC), and maintenance of physical activity after college. In general, participating athletes reported influences within their social and physical environments (friends, bar accessibility, etc.) as the leading enablers of their excessive alcohol intake, while individual level influences were the most salient reasons not to drink excessively (responsibilities, health, etc.). Individual characteristics (taste preference, health, and expense) and the physical environment (availability and accessibility) were reported as the most salient levels of influence on athletes’ FVC. And when anticipating future maintenance of physical activity, athletes mostly reported individual level influences (outcome expectation, intrinsic motivation, etc.), with mention of family and friend influences. An in-depth comparison of current outcomes to similar research among young adult and athlete populations is provided, including validated measurement scales and future research suggestions. Current results provide an essential foundation for progressive research examinations among similar populations.展开更多
