Irritable bowel syndrome (IBS) is a prevalent disorder of gut-brain function associated with psychological distress as well as work and quality of life impairment. Smoking has been linked to gastrointestinal dysfunction, however, research focused on the prevalence of IBS and smoking is limited. Previous research has shown that anxiety sensitivity is linked to increased risk of aversive bodily experiences and subsequent coping-oriented regulation efforts. Higher anxiety sensitivity has also been associated with processes linked to tobacco cigarette smoking lapse and relapse. There is a need to clarify the explanatory roles of anxiety sensitivity in the context of more severe IBS symptoms among persons with IBS who are current smokers.
The present investigation evaluated the main and interactive effects of IBS symptom severity and anxiety sensitivity in relation to processes related to the maintenance and relapse of tobacco smoking among adults with IBS. The sample consisted of 263 (52.1 % female; M = 44.13 years, SD = 12.71) adults who met criteria for IBS and smoke at least 5 cigarettes per day.
Hierarchical regression results indicated that both anxiety sensitivity and IBS symptom severity independently predicted greater perceived barriers to smoking cessation, severity of problems experienced during quitting, and negative reinforcement smoking expectancies. A statistically significant interaction further indicated that IBS symptom severity was more strongly associated with negative reinforcement smoking expectancies among participants with higher, relative to lower, anxiety sensitivity.
This study is the first to show that both IBS symptom severity and anxiety sensitivity are related to greater perceived barriers to smoking cessation, previous difficulty quitting, and negative reinforcement expectancies among adults with IBS. There is a continued need to further scientific understanding of interrelations between anxiety sensitivity, IBS symptom severity, and smoking cessation-related beliefs and processes to identify novel approaches that can best support quitting among this understudied population.
肠易激综合征（IBS）是一种常见的肠-脑功能紊乱疾病，与心理困扰以及工作和生活质量受损有关。吸烟与胃肠道功能障碍有关，然而，关于 IBS 和吸烟流行率的研究有限。先前的研究表明，焦虑敏感性与厌恶的身体体验的风险增加以及随后的应对导向的调节努力有关。较高的焦虑敏感性也与与烟草香烟吸烟发作和复发相关的过程有关。需要澄清在 IBS 症状更严重的情况下，焦虑敏感性在当前吸烟者中 IBS 患者中的解释作用。
本研究评估了 IBS 症状严重程度和焦虑敏感性与与 IBS 成年人吸烟维持和复发相关的过程之间的主要和交互作用。样本包括 263 名（52.1%女性；M=44.13 岁，SD=12.71）符合 IBS 标准且每天至少吸烟 5 支的成年人。
层次回归结果表明，焦虑敏感性和 IBS 症状严重程度独立预测戒烟时的感知障碍更大、戒烟期间问题的严重程度以及消极强化吸烟预期。进一步的统计学显著交互作用表明，在焦虑敏感性较高的参与者中，IBS 症状严重程度与消极强化吸烟预期的相关性更强。
这项研究首次表明，IBS 症状严重程度和焦虑敏感性都与成年人中更大的戒烟感知障碍、先前戒烟困难和消极强化预期有关。需要进一步科学理解焦虑敏感性、IBS 症状严重程度和与戒烟相关的信念和过程之间的相互关系，以确定可以最好地支持这一研究不足的人群戒烟的新方法。
