INTRODUCTION There is growing evidence that implicit theories of smoking-whether smokers perceive smoking behavior as malleable or fixed-are significant predictors of quitting intentions. The present study aims to investigate the underlying mechanisms of implicit theories on smoking in predicting smokers' intentions to quit. METHODS This was a cross-sectional study. We conducted multiple linear regression with quitting intentions as the dependent variable, implicit theories of smoking as the independent variable, and sociodemographic variables, quitting attempts in the past year, and whether receiving quitting advice in the past 12 months as the covariates. The mediating role of consideration of future consequences and self-efficacy in the relationship between ITS and quitting intentions was evaluated by mediation analyses. RESULTS A total of 510 smokers were included in the final analyses. Smokers holding a higher incremental theory of smoking reported a higher likelihood of considering future consequences (β = 0.289, p < 0.001) and a weaker possibility of considering immediate results (β = -0.317, p < 0.001), which, in turn, enhanced their quitting self-efficacy and then led to stronger intentions to quit smoking (β = 0.261, p < 0.001). CONCLUSIONS The current study enriched our understanding of the underlying mechanisms that connect smokers' implicit theories of smoking and their likelihood of smoking cessation such that higher incremental theories of smoking predict stronger intention to quit smoking, and the effect was serially mediated by smokers' likelihood of considering future consequences of their behavior and their perceived self-efficacy for smoking cessation. IMPLICATIONS This study indicated the mediating role of consideration of future consequences and self-efficacy for smoking cessation on the relationship between the implicit theories of smoking and quitting intentions. These two psychological factors and the pathways may be important points for understanding the model of implicit theories for smoking and improving the effectiveness of implicit theories-based intervention on smoking cessation.

吸烟和戒烟意愿的内隐理论：串行中介模型。

引言 越来越多的证据表明，吸烟的隐含理论（吸烟者是否认为吸烟行为是可塑的还是固定的）是戒烟意图的重要预测因素。本研究旨在探讨吸烟隐含理论预测吸烟者戒烟意图的潜在机制。方法 这是一项横断面研究。我们进行了多元线性回归，以戒烟意愿为因变量，吸烟的隐含理论为自变量，社会人口统计学变量、过去一年的戒烟尝试以及过去 12 个月是否接受戒烟建议作为协变量。通过中介分析评估了考虑未来后果和自我效能感在 ITS 与戒烟意向之间关系中的中介作用。结果 最终分析共纳入 510 名吸烟者。持有较高吸烟增量理论的吸烟者报告考虑未来后果的可能性较高（β = 0.289，p < 0.001），而考虑即时结果的可能性较弱（β = -0.317，p < 0.001），这反过来又增强了他们的戒烟自我效能，然后导致更强烈的戒烟意愿（β = 0.261，p < 0.001）。结论 目前的研究丰富了我们对吸烟者内隐吸烟理论与其戒烟可能性之间联系的潜在机制的理解，即较高的吸烟渐进理论预示着更强的戒烟意愿，并且该效应是由吸烟者的戒烟可能性连续介导的。考虑他们的行为的未来后果以及他们对戒烟的自我效能感。意义 这项研究表明，考虑戒烟的未来后果和自我效能感在吸烟的内隐理论与戒烟意向之间的关系中发挥着中介作用。这两个心理因素及其路径可能是理解吸烟内隐理论模型、提高内隐理论戒烟干预效果的重要切入点。
