This study was designed to examine the moderating influence of habit strength on daily action planning effects on physical activity and sedentary behavior. A 2 by 2 design was used with experimental factors corresponding to action planning interventions for (a) engaging in physical activity and (b) limiting or interrupting sedentary behavior. At the end of each day for 1 week, university students (n = 195) completed (a) a questionnaire about their behavior during the day and behavioral intentions for the following day and (b) a planning intervention(s) corresponding to their randomly assigned experimental condition. Action planning increased physical activity in those with weak habits but decreased physical activity in those with strong habits compared with those who did not create action plans. Action planning did not impact sedentary behavior. Action planning was a useful behavior change technique for increasing physical activity in people with weak habits, but may be iatrogenic for those with strong habits.
本研究旨在检验习惯强度对日常行动规划对身体活动和久坐行为影响的调节作用。采用2×2设计，实验因素对应于（a）进行身体活动和（b）限制或中断久坐行为的行动规划干预措施。在为期1周的每一天结束时，大学生（n = 195）完成了（a）一份关于他们当天行为及次日行为意图的问卷，以及（b）与他们随机分配的实验条件相对应的规划干预措施。与未制定行动计划的人相比，行动规划增加了习惯较弱者的身体活动，但减少了习惯较强者的身体活动。行动规划对久坐行为没有影响。行动规划是一种有用的行为改变技术，可增加习惯较弱者的身体活动，但对习惯较强者可能产生医源性影响。
