The purpose of this study is twofold: to identify the determinants of daily fruit and vegetable (F&V) consumption and the moderators of the intention-behaviour relationship. A sample of 225 overweight or obese adults completed a TPB questionnaire. F&V behaviour was assessed at baseline and three months later. Statistical analyses revealed that past behaviour, perceived behavioural control (PBC) and age were significant predictors of daily F&V consumption. In addition, intention was found to interact with anticipated regret. Interventions should encourage the development of habit and PBC. However, the age and level of anticipated regret of the targeted population should be considered when designing interventions.
确定每日水果和蔬菜（F&V）消费的决定因素，以及意图-行为关系的调节因素。本研究共纳入了 225 名超重或肥胖成年人，他们完成了 TPB 问卷。F&V 行为在基线和三个月后进行评估。统计分析显示，过去的行为、感知行为控制（PBC）和年龄是每日 F&V 消费的显著预测因素。此外，意图被发现与预期后悔相互作用。干预措施应鼓励习惯和 PBC 的发展。然而，在设计干预措施时，应考虑目标人群的年龄和预期后悔水平。
