With a direct link between traumatic stress and poor smoking outcomes established, there is a clinically important need to identify underlying, targetable mechanisms that maintain these relations. The present study employed a parallel mediation model to assess the competing explanatory significance of four distinct facets of depression and anxiety (general anxiety, anxious arousal, general depression, and anhedonic depression) in the relation between traumatic load and perceived barriers for quitting smoking, severity of psychosomatic problems experienced when attempting to quit smoking in the past, and negative reinforcement expectancies related to smoking among 98 adult trauma-exposed daily smokers (M_age = 44.64, SD = 10.66). Results showed that only general anxiety symptoms, when controlling for the competing facets of depression and anxiety, had a statistically significant indirect effect on the relation between traumatic load and all smoking processes, such that general anxiety symptoms significantly, indirectly influenced the relation between traumatic load and barriers for smoking cessation (ab = 0.95, 95% CI [0.163, 0.2.14]), smoking quit problems (ab = 0.07, 95% CI [0.009, 0.165]), and negative reinforcement smoking expectancies (ab = 0.16, 95% CI [0.025, 0.399]). Anxious arousal demonstrated an indirect effect for trauma load on only negative reinforcement smoking expectancies (ab = -0.15, 95% CI [-0.345, -0.023]). The current findings highlight the potential importance of general anxiety symptoms as a targetable mechanism for smoking cessation treatments for trauma-exposed smokers.

由于创伤性应激与不良吸烟结果之间存在直接联系，因此临床上迫切需要确定维持这些关系的潜在的、可针对的机制。本研究采用平行中介模型来评估抑郁和焦虑的四个不同方面（一般性焦虑、焦虑性唤醒、一般性抑郁和快感缺乏性抑郁）在创伤负荷和感知戒烟障碍、严重程度之间的关系中的相互竞争的解释意义。过去尝试戒烟时经历的心身问题，以及 98 名遭受创伤的成年吸烟者中与吸烟相关的负强化预期（M_年龄 = 44.64，SD = 10.66）。结果表明，在控制抑郁和焦虑的相互竞争方面时，只有一般性焦虑症状对创伤负荷与所有吸烟过程之间的关系具有统计显着的间接影响，因此一般性焦虑症状显着地间接影响创伤负荷与吸烟过程之间的关系。戒烟障碍（ab = 0.95，95% CI [0.163，0.2.14]）、戒烟问题（ab = 0.07，95% CI [0.009，0.165]）和负强化吸烟预期（ab = 0.16， 95% CI [0.025, 0.399]）。焦虑唤醒证明创伤负荷仅对负强化吸烟预期产生间接影响（ab = -0.15，95% CI [-0.345，-0.023]）。目前的研究结果强调了一般性焦虑症状作为针对遭受创伤的吸烟者戒烟治疗的有针对性的机制的潜在重要性。
