目标：规划可以弥合意图和行动之间的鸿沟，但是什么弥合了规划和行动之间的鸿沟？这项研究通过解开自我效能感、计划和准备行为之间的相互关系来帮助回答这个问题，以预测身体活动。将准备行为作为规划的一种工作机制进行测试。此外，还检验了准备行为的效用是否取决于个人的自我效能感水平。方法：一项调查评估了计划、自我效能和身体活动的准备行为。成年人(N=166)提供了两个测量点的数据。在纵向模型中，准备行为被指定为计划和体力活动之间的中介。自我效能感在模型中的两个点被指定为一个可能的调节变量。结果：准备行为在计划和体力活动之间的关系中起中介作用。研究发现，自我效能感与身体活动的准备行为之间存在交互作用，表明自我效能感较低的个体如果更频繁地参与准备行为，就会更加活跃。结论：计划似乎刺激了准备行为，这反过来又使未来进行身体活动的可能性更大。此外，由于执行准备行为是朝着制定行为目标迈出的一步，准备行为可能对那些对身体活动自我怀疑的人特别有益。
Objective: Planning can bridge the gap between intentions and action, but what bridges the gap between planning and action? This study helps to answer the question by disentangling the interrelationships between self-efficacy, planning and preparatory behaviours in predicting physical activity. Preparatory behaviours are tested as a working mechanism of planning. Moreover, it is tested whether the utility of preparatory behaviours depends on an individual's level of self-efficacy.Methods: A survey assessed planning, self-efficacy and preparatory behaviours for physical activity. Adults (N=166) provided data at two measurement points. In a longitudinal model, preparatory behaviours were specified as a mediator between planning and physical activity. Self-efficacy was specified as a possible moderator at two points in the model.Results: Preparatory behaviours mediated the relationship between planning and physical activity. An interaction between self-efficacy and preparatory behaviours on physical activity was found, indicating that individuals with low self-efficacy beliefs were more active if they engaged more frequently in preparatory behaviours.Conclusion: Planning seems to stimulate preparatory behaviours, which in turn make future physical activity more likely. Furthermore, as performing preparatory behaviours represent a step forward towards the enactment of behavioural goals, preparatory behaviours may be particular beneficial for individuals afflicted by self-doubts regarding physical activity.
