Despite the advances in understanding the relationship between smoking and depressive symptomatology, scarce research has investigated cognitive variables underlying in such relation. The main aim of this study is to examine the mediating effect of two rumination subtypes (brooding and reflection) in the link between depressive symptoms and both cigarette dependence level and tobacco craving in treatment-seeking smokers. Participants were 275 adult daily smokers seeking treatment to quit smoking (61.5% females; Mage = 45.3 years; SD = 10.9). Multiple mediation analysis was conducted to explore the mediating effects of rumination (brooding and reflection) in the relation between depressive symptoms, cigarette dependence level, and craving. Results showed a significant indirect effect of depressive symptoms through the joint of both rumination subtypes on cigarette dependence (β = 0.089; 95% BootCI [0.006, 0.168]), and craving (β = 0.123; 95% BootCI [0.048, 0.205]). The specific analysis of each mediator showed that only brooding subtype had a significant effect on the relation between depressive symptoms and tobacco craving (β = 0.101; 95% BootCI [0.023, 0.186]). Findings of the present study provide further evidence for the role of rumination in smoking-related variables and for the potential value of introducing rumination-focused interventions into smoking-cessation interventions.

寻味是否可以在寻求治疗的吸烟者中缓解抑郁症状对香烟依赖和渴望的影响？

尽管在了解吸烟与抑郁症状之间的关系方面取得了进步，但很少有研究调查了这种关系中潜在的认知变量。这项研究的主要目的是检验在寻求治疗的吸烟者中，两种反刍亚型（沉思和反思）在抑郁症状与香烟依赖水平和烟草渴望之间的关系。参与者为275名每日成年吸烟者，他们正在寻求戒烟治疗（61.5％的女性；法师= 45.3岁； SD = 10.9）。进行了多种中介分析，以探讨反刍（沉思和反思）在抑郁症状，香烟依赖程度和渴望之间的中介作用。结果显示，通过两种反刍亚型的关节，抑郁症状对香烟依赖（β= 0.089； 95％BootCI [0.006，0.168]）和渴望（β= 0.123； 95％BootCI [0.048，0.205]）具有显着的间接作用。 。对每种介体的特异性分析表明，只有育雏亚型对抑郁症状与烟草渴望之间的关系具有显着影响（β= 0.101； 95％BootCI [0.023，0.186]）。本研究的发现为反刍在吸烟相关变量中的作用以及将反刍集中干预措施引入戒烟干预措施的潜在价值提供了进一步的证据。对每种介体的特异性分析表明，只有育雏亚型对抑郁症状与烟草渴望之间的关系具有显着影响（β= 0.101； 95％BootCI [0.023，0.186]）。本研究的发现为反刍在吸烟相关变量中的作用以及将反刍集中干预措施引入戒烟干预措施的潜在价值提供了进一步的证据。对每种介体的特异性分析表明，只有育雏亚型对抑郁症状与烟草渴望之间的关系具有显着影响（β= 0.101； 95％BootCI [0.023，0.186]）。本研究的发现为反刍在吸烟相关变量中的作用以及将反刍集中干预措施引入戒烟干预措施的潜在价值提供了进一步的证据。
