This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. In critiquing the research agenda associated with increasing physical activity levels among Americans, Baranowski et al. (1998) state that it is crucial to demonstrate that a particular theory / construct accounts for significant variance (i.e., ¿ 30%) in a target behavior (e.g., moderate-intensity physical activity) before theoretically-based interventions can be successfully developed. Furthermore, Baranowski et al. (1998) and Healthy People 2010 suggest that the moderating impact of ethnicity on the theory / target behavior relationship is an important issue to consider, particularly in post-secondary institutions. African-Americans are more sedentary compared to Caucasians, which places them at greater risk for developing various chronic diseases. The purpose of the proposed studies is to use the theory of planned behavior (TPB) to identify key global determinants (i.e., attitudes, subjective norms, perceived behavioral control) and accessible beliefs (i.e., behavioral, normative, control) in college-aged African-Americans and Caucasians. These findings will allow future researchers to focus on developing ethnically relevant physical activity interventions. Four studies will be conducted to achieve this goal. First, a pilot study will be conducted to generate the accessible beliefs proposed by the TPB. These beliefs will be put into questionnaire format and tested in a second study for comprehension and readability. Next, the test-retest reliability of the modified questionnaire from study two will be examined in study three. Finally, the fourth study will administer the TPB questionnaire to 416 African-Americans and 416 Caucasians who will be followed up at three and six months. This research plan will allow us to assess which determinants and beliefs are associated with moderate-intensity physical activity levels in both groups.

该子项目是利用NIH/NCRR资助的中心赠款提供的资源的许多研究子项目之一。子项目和研究者（PI）可能从另一个NIH来源获得主要资金，因此可以在其他CRISP条目中表示。所列机构为中心，不一定是研究者所在机构。在批评与美国人身体活动水平增加相关的研究议程时，Baranowski等人（1998）指出，关键是要证明一个特定的理论/结构解释了显著的差异（即，30%）在目标行为中（例如，中等强度的体力活动），然后才能成功地开发基于理论的干预措施。此外，Baranowski等人（1998）和Healthy People 2010表明，种族对理论/目标行为关系的调节作用是一个需要考虑的重要问题，特别是在中学后机构。与白人相比，非洲裔美国人更久坐不动，这使他们患各种慢性疾病的风险更大。拟议研究的目的是使用计划行为理论（TPB）来确定关键的全球决定因素（即，态度、主观规范、感知的行为控制）和可接近的信念（即，行为，规范，控制）在大学年龄的非洲裔美国人和白人。这些发现将使未来的研究人员能够专注于开发与种族相关的身体活动干预措施。为实现这一目标，将进行四项研究。首先，我们会进行一项试验研究，以产生城规会所建议的易接近信念。这些信念将被放入问卷格式，并在第二次研究的理解和可读性测试。接下来，研究三将检验研究二修改后的问卷的重测信度。最后，第四项研究将对416名非洲裔美国人和416名白人进行TPB问卷调查，并在3个月和6个月时进行随访。这项研究计划将使我们能够评估哪些决定因素和信念与两组中的中等强度体力活动水平相关。
