Pursuit of physical activity goals often requires modifying plans, but research on these flexible processes is limited. Cognitive flexibility may heighten one's likelihood of using flexible self-regulatory strategies (e.g., substitution), thereby increasing physical activity. This study used daily diary methodology to test the indirect effect of cognitive flexibility on physical activity via activity substitution. A sample of 128 college students (73% female, mean age 19.9) completed baseline measures and cognitive flexibility assessments, then logged physical activity daily for 2 weeks. Activity substitution was defined as adopting an alternate activity on a day another planned activity was unfulfilled. Controlling for baseline activity, intentions, and time, a multilevel mediation model revealed a significant indirect effect of cognitive flexibility on physical activity via activity substitution (b = 81.36, p = .041). Our results indicate that people with greater cognitive flexibility are more likely to use flexible self-regulation, leading to greater physical activity.
追求身体活动目标通常需要调整计划，但关于这些灵活过程的研究有限。认知灵活性可能会提高一个人使用灵活自我调节策略（如替代）的可能性，从而增加身体活动。本研究采用每日日记法来检验认知灵活性通过活动替代对身体活动产生的间接影响。128名大学生样本（73%为女性，平均年龄19.9岁）完成了基线测量和认知灵活性评估，然后连续两周每天记录身体活动情况。活动替代被定义为在一天中当另一个计划活动未完成时采用替代活动。在控制了基线活动、意图和时间后，一个多层次中介模型显示认知灵活性通过活动替代对身体活动产生显著的间接影响（b = 81.36，p = .041）。我们的结果表明，认知灵活性较高的人更有可能使用灵活的自我调节，从而带来更多的身体活动。
