This study investigated intentions and self-efficacy of physically active university students towards healthy eating. The application of Planned Behavior theory has shown that attitudes, intention, perceived behavioral control, and subjective norms play an important role in shaping people's behavior. 96 students, who participated in physical activities, voluntarily completed the Questionnaire for the Planned Behavior Model and the Health Behavior Questionnaire. The former examines attitudes, intentions, perceived behavioral control, and the lately added attitude strength, and role identity towards the behavior factors. The latter assesses one's efficacy expectations towards healthy eating. The regression showed strong associations between the examined variables, signifying that attitudes, perceived behavioral control, and role identity could account for one's intention towards healthy eating behaviors. On the other hand, one's self-efficacy for healthy eating could be explained from the attitudes, intention, perceived behavioral control, and attitude strength held. Overall, systematic participation in physical activities appeared to be accompanied with a relatively healthier diet, while self-efficacy had a significant association with maintaining the healthy eating behaviors. Possible interpretations, limitations, and implications for health professionals are discussed.
本研究调查了积极参加体育活动的大学生对健康饮食的意图和自我效能感。计划行为理论的应用表明,态度、意图、感知行为控制和主观规范在塑造人们的行为方面起着重要作用。96名参加体育活动的学生自愿完成了计划行为模型问卷和健康行为问卷。前者考察态度、意图、感知行为控制以及最近新增的态度强度和对行为因素的角色认同。后者评估一个人对健康饮食的效能期望。回归分析显示,所考察的变量之间存在很强的关联,这表明态度、感知行为控制和角色认同可以解释一个人对健康饮食行为的意图。另一方面,一个人对健康饮食的自我效能感可以从所持有的态度、意图、感知行为控制和态度强度中得到解释。总体而言,系统地参加体育活动似乎伴随着相对更健康的饮食,而自我效能感与保持健康饮食行为有显著关联。文中还讨论了可能的解释、局限性以及对健康专业人员的启示。
