DESCRIPTION (provided by applicant): The transition from adolescence to young adulthood is marked by declines in healthful behaviors such as diet, physical activity, and increases in obesity, thereby establishing early patterns of unhealthful behaviors in mid-adulthood that can lead to increases in chronic diseases later in life. Health promotion interventions in the college setting may have an impact on these patterns. However, because the U.S. undergraduate college population consists largely (3/4) of nontraditional students, health promotion programming should incorporate the characteristics that are germane to this population (for example, part-time enrollment, working full-time, and commuting to campus). These characteristics add to college students' social context, a theoretical multi-level concept that stresses the influence of social and organizational influences on the practice of health behaviors. Therefore, the purpose of this study is to evaluate the feasibility of implementing an intervention incorporating students' social context to promote healthy eating and physical activity behaviors among nontraditional college students. First, adaptations to existing intervention materials available to the study team will be carried out in order to create the three main components for the proposed intervention: 1) web-based tailored feedback, 2) web-based tip sheets targeted to the social context of the college setting, and 3) four phone-based coaching calls using motivational interviewing. The coaching calls will be delivered by trained student peer counselors, a potentially sustainable delivery mechanism. Second, the feasibility of the intervention will be assessed using a one-group, pre/post design among a sample of 100 students enrolled at a large 4-year public university serving a large population of nontraditional students. This design will allow us to investigate feasibility of the intervention approach among student peer counselors and student participants by meeting benchmarks based on previous studies. The four benchmarks are: 1) training a sufficient number of student peer counselors, 2) having participants receive a sufficient dose of coaching calls, 3) having participants receive a sufficient dose of tailored and targeted materials, and 4) having student peer counselors adhere sufficiently to key principles of motivational interviewing during the coaching calls. Meeting each benchmark will be measured by a specific process indicator. Third, we will assess change in behaviors (fruit and vegetable intake, moderate-to-vigorous physical activity) among student participants from baseline to five-month follow-up. Thus, this application seeks to: 1) create a series of intervention materials, 2) conduct a feasibility assessment of our intervention approach, and 3) obtain an effective size estimation necessary in order to conduct a future intervention trial.

描述（由申请人提供）：从青春期到年轻成年的过渡以健康行为的下降（例如饮食，体育锻炼和肥胖症的增加）的下降，从而确立了早期不健康行为的早期模式，这些模式可能导致慢性疾病的增长。大学环境中的健康促进干预措施可能会对这些模式产生影响。但是，由于美国本科大学的人口主要是（3/4）的非传统学生，因此健康促进计划应纳入对该人群的特征（例如，兼职，全职，全职工作以及到校园的通勤）。这些特征增加了大学生的社会环境，这是一个理论上的多层次概念，强调了社会和组织影响对健康行为实践的影响。因此，本研究的目的是评估实施干预措施的可行性，该干预措施结合了学生的社会环境，以促进非传统大学生中的健康饮食和体育锻炼行为。首先，将对研究团队可用的现有干预材料进行改编，以创建针对拟议的干预措施的三个主要组成部分：1）基于Web的量身定制反馈，2）针对大学环境的社会环境的基于Web的小费表，以及3）四个基于电话的教练呼叫。教练的电话将由受过训练的学生同伴辅导员（一种潜在可持续的交付机制）进行。其次，将在100名学生中的100名学生中，在一所大型4年公立大学中招收的100名学生中，将对干预措施的可行性进行评估，为大量的非传统学生提供服务。这种设计将使我们能够根据以前的研究符合基准测试，调查学生同伴辅导员和学生参与者中干预方法的可行性。这四个基准是：1）培训足够数量的学生同伴辅导员，2）让参与者接收足够的教练电话，3）让参与者获得足够剂量的量身定制和有针对性的材料，以及4）让学生同伴在教练电话期间足够遵守激励访谈的关键原理。满足每个基准测试将通过特定的过程指标来衡量。第三，我们将评估从基线到五个月随访的学生参与者的行为变化（水果和蔬菜摄入量，中度到vim的体育锻炼）。因此，本应用程序试图：1）创建一系列干预材料，2）对我们的干预方法进行可行性评估，3）获得必要的有效尺寸估计，以进行以后的干预试验。
