Both explicit and implicit motivational processes predict physical activity (PA); however, their respective contributions may depend on interindividual differences. This study examined the moderating role of trait impulsivity and executive functions in the associations between PA intentions, implicit attitudes toward sedentary behavior, and PA measured with accelerometers in persons with obesity.
Participants (N = 76; Mage = 56 years, SD = 11.9; MBody Mass Index = 39.1, SD = 6.5) completed baseline questionnaires measuring their PA intentions and trait impulsivity. They also performed 2 computerized tests measuring implicit attitudes toward sedentary behavior and executive functions. PA was assessed 4 months later with an accelerometer.
Implicit attitudes toward sedentary behavior and executive functions interacted to predict PA. Higher implicit attitudes were associated with significantly lower PA in participants with low and moderate executive functions but not high executive functions.
These results support the role of implicit processes and cognitive factors in health-related behavior adoption through time. Practically, these variables may be useful to identify individuals at risk of abandoning PA after programs who thus may benefit from complementary interventions (e.g., provide feedback on implicit attitudes and develop self-regulatory skills).

明确和隐含的动机过程都可以预测身体活动（PA）；然而，它们各自的贡献可能取决于个体差异。本研究考察了特质冲动性和执行功能在肥胖人群中 PA 意向、久坐行为的内隐态度与加速度计测量的 PA 之间的关系中的调节作用。
参与者（N=76；平均年龄=56 岁，标准差=11.9；平均体重指数=39.1，标准差=6.5）在基线时完成了测量 PA 意向和特质冲动性的问卷。他们还进行了 2 项测量久坐行为内隐态度和执行功能的计算机测试。4 个月后用加速度计评估 PA。
久坐行为的内隐态度和执行功能相互作用，共同预测 PA。在执行功能较低和中等的参与者中，较高的内隐态度与 PA 显著降低相关，但在执行功能较高的参与者中则不然。
这些结果支持了隐含过程和认知因素在随时间推移的健康相关行为采用中的作用。实际上，这些变量可以用来识别在项目后可能放弃 PA 的高危个体，从而使他们受益于补充干预措施（例如，提供内隐态度的反馈和发展自我调节技能）。（《心理科学数据库记录》）
