The authors attempt to show the usefulness of discriminate messages designed to increase college students' intentions to engage in physical activities.
The authors selected a sample of undergraduate students enrolled in communication courses at a university in the southeastern United States for a baseline online survey (n=683) and an experiment (n=99).
The authors selected discriminate beliefs with highest regression weights and sizable effect size with behavioral intention to build messages for classroom intervention. The authors used an analysis of covariance to test the intervention effect of discriminate messages on intention to do physical activities.
Students exposed to the discriminate messages were more likely to report positive changes in their self-efficacy and behavioral intentions related to physical activity.
Further research on communication theories is required to help design the selected beliefs so that they will be comprehended and ultimately lead to behavioral changes.
作者试图展示旨在提高大学生参与体育活动意愿的有针对性信息的效用。
作者选取了美国东南部一所大学通信课程的本科生样本，进行基线在线调查（n = 683）和一项实验（n = 99）。
作者选择了与行为意图具有最高回归权重和可观效应量的有针对性信念，以构建用于课堂干预的信息。作者使用协方差分析来测试有针对性信息对体育活动意愿的干预效果。
接触到有针对性信息的学生更有可能报告他们与体育活动相关的自我效能和行为意图有积极变化。
需要对传播理论进行进一步研究，以帮助设计选定的信念，使其能够被理解并最终导致行为改变。
