Action planning is a common approach used in physical activity interventions. The aim of this study was to assess the association of frequency, consistency and content of action planning with physical activity behaviour, intention strength and habit strength.
Within a 3-month web-based, computer-tailored physical activity intervention, participants ( = 115; 68.7% female, age =43.9; range = 22-73 years) could create 6 rounds of action plans for 4 activities each (24 total).
Consistency of action planning during the intervention was associated with change in physical activity at 9-months, and intention and habit strength at 3-months and 9-months. Frequency of action planning was negatively associated with intention at 3-months and 9-months. The effect of action planning consistency on physical activity behaviour was no longer significant when accounting for change in intention and habit strength.
Consistency of how, where, when and with whom people plan their physical activity may translate into stronger physical activity habits. Interventions should avoid encouraging making many distinct action plans, but rather encourage stable contexts through consistent action planning.
行动计划是体育活动干预中常用的一种方法。本研究旨在评估行动计划的频率、一致性和内容与体育活动行为、意图强度和习惯强度之间的关联。
在一项为期3个月的基于网络的、计算机定制的体育活动干预中，参与者（n = 115；68.7%为女性，年龄 = 43.9岁；范围 = 22 - 73岁）可为4项活动各制定6轮行动计划（共24项）。
干预期间行动计划的一致性与9个月时体育活动的变化以及3个月和9个月时的意图和习惯强度相关。行动计划的频率在3个月和9个月时与意图呈负相关。在考虑意图和习惯强度的变化后，行动计划一致性对体育活动行为的影响不再显著。
人们计划体育活动的方式、地点、时间和对象的一致性可能转化为更强的体育活动习惯。干预措施应避免鼓励制定许多不同的行动计划，而应通过一致的行动计划鼓励稳定的情境。
