Anxiety sensitivity (AS) is associated with poor smoking cessation outcomes. One reason may be that smokers with high AS smoke differently (i.e., to manage negative affect and uncomfortable bodily sensations) than other smokers, leading to stronger addiction (due to an affect/sensation based and thereby highly variable rather than a regular smoking routine). Thus, we examined the relationship between AS and smoking variability in a group of treatment-seeking smokers.
Participants ( = 136; 52.2% female; M = 44.19 years, SD = 11.29) were daily smokers with elevated AS (AS≥20 on the Anxiety Sensitivity Index 16-item at prescreen) recruited as part of a larger randomized controlled trial for smoking cessation. Most participants were Caucasian (73%), educated (with 76% attending some college), unmarried (73%), and employed full-time (56%). They smoked, on average, 17 cigarettes per day.
Consistent with prediction, a regression analysis of baseline assessments and a longitudinal analysis with multilevel modeling (MLM) both showed higher AS was associated with greater variability in cigarettes smoked per day while controlling for gender, age, ethnicity, and income.
This finding encourages investigation of how AS might interact with clinical strategies using a fixed smoking taper as part of quit attempts.
焦虑敏感性（AS）与戒烟效果不佳有关。一个原因可能是，高AS的吸烟者吸烟方式与其他吸烟者不同（即，为了控制负面情绪和身体不适感觉），导致更强的成瘾性（由于基于情绪/感觉，因此高度可变，而不是常规的吸烟习惯）。因此，我们在一组寻求治疗的吸烟者中研究了AS与吸烟变异性之间的关系。
参与者（n = 136；52.2%为女性；M = 44.19岁，SD = 11.29）是在预筛查时焦虑敏感性指数16项得分≥20的每日吸烟者，作为一项更大规模的戒烟随机对照试验的一部分被招募。大多数参与者是白人（73%），受过教育（76%上过大学），未婚（73%），并且全职工作（56%）。他们平均每天吸17支烟。
与预测一致，对基线评估的回归分析和使用多层模型（MLM）的纵向分析均显示，在控制性别、年龄、种族和收入的情况下，较高的AS与每天吸烟量的更大变异性相关。
这一发现鼓励研究AS如何与使用固定吸烟减量法作为戒烟尝试一部分的临床策略相互作用。
