目标：大多数大学生未能达到推荐的运动水平，并且参与方面的种族差异很明显。本研究探讨了种族、计划行为理论（TPB）和运动之间的调节和中介关系，并确定了与运动相关的共同和种族特异性信念。方法：大学生在两周内完成了基线TPB问卷和运动评估。（n = 237名黑人; n = 176名白人）或2个月（n = 280名黑人; n = 273名白人）随访。设计：一周和两个月纵向设计。结果：结构方程模型表明，TPB是不变的种族在这两个样本的情感态度和感知行为控制，意图的显着预测因子，反过来，显着预测运动。此外，分析表明，TPB有一个小的中介作用的种族/运动的关系，在两个样本。最后，共同的和种族的具体信念，不同的sample.Conclusion：TPB是一个有用的框架来解释运动行为在黑人和白色学生，但是，它的能力来解释运动的种族差异可能是有限的。(C)2007爱思唯尔有限公司保留所有权利。
Objectives: Most college students fail to meet recommended exercise levels and ethnic disparities in participation are apparent. The present study examined the moderating and mediating relationships among ethnicity, the theory of planned behavior (TPB), and exercise, and identified common and ethnic-specific beliefs related to exercise.Method: College students completed a baseline TPB questionnaire and an exercise assessment at either two-week (n = 237 blacks; n = 176 whites) or two-month (n = 280 blacks; n = 273 whites) follow-ups.Design: One week and two month longitudinal designs.Results: Structural equation modeling showed that the TPB was invariant by ethnicity in both samples with affective attitudes and perceived behavioral control being significant predictors of intention, which in turn, significantly predicted exercise. Furthermore, analyses showed that the TPB had a small mediating effect on the ethnicity/exercise relationship in both samples. Finally, common and ethnic-specific beliefs were identified that varied by sample.Conclusion: The TPB is a useful framework to explain exercise behavior in black and white students; however, its ability to explain the ethnic disparity in exercise may be limited.
