A test of the interactive effects of anxiety sensitivity and mindfulness in the prediction of anxious arousal, agoraphobic cognitions, and body vigilance

The present investigation sought to examine the interactive effects of anxiety sensitivity [AS; Reiss, S., & McNally, R. J. (1985). Expectancy model of fear. In S. Reiss, & R. R. Bootzin (Eds.), Theoretical issues in behavior therapy (pp. 107-121). San Diego: Academic Press] and mindfulness [Brown, K. W., & Ryan, R. M. (2003). The benefit of being present: Mindfulness and its role in psychological well-being. Journal of Personality and Social Psychology, 84, 822-848] in predicting panic-relevant processes. A community sample of 248 individuals participated in the study by completing a battery of self-report instruments. Consistent with prediction, the interaction between AS and mindfulness significantly predicted anxious arousal symptoms and agoraphobic cognitions, above and beyond the individual main effects, and did not significantly predict anhedonic depression symptoms. Contrary to prediction, the AS by mindfulness interaction did not significantly predict body vigilance. Theoretical implications are discussed and future directions are delineated.     

Anxiety sensitivity interacts with marijuana use in the prediction of anxiety symptoms and panic-related catastrophic thinking among daily tobacco users

The present investigation evaluated whether anxiety sensitivity interacted with marijuana use in relation to the prediction of panic-relevant variables among young adult tobacco smokers (n=265). Approximately 73% of the sample was composed of current marijuana smokers, with 78.5% of this sub-sample using marijuana more than once per week. As expected, after covarying cigarettes per day, alcohol use, and negative affectivity, the interaction between marijuana use and anxiety sensitivity predicted anxiety symptoms and agoraphobic cognitions. Partially consistent with prediction, the interaction between frequency of marijuana use and anxiety sensitivity predicted only anxiety symptoms. These results are discussed in relation to better understanding the potential role of regular marijuana use and anxiety sensitivity for panic-relevant emotional vulnerability among regular tobacco smokers.     

Evaluating the role of anxiety sensitivity in barriers to cessation and reasons for quitting among smokers with asthma

The aim of the present study was to examine the unique predictive ability of anxiety sensitivity (AS) in terms of perceived barriers to cessation and smoking cessation motives among daily smokers with asthma (n = 125, 54% male, M_age = 37.7 years, SD = 12.1). As hypothesized, after controlling for the effects of race, asthma control, negative affect, and smoking rate, AS significantly predicted greater barriers to cessation, and reasons for quitting related to health concerns and self-control. Contrary to hypotheses, AS did not significantly predict external reasons for quitting. These findings suggest that smokers with asthma who are fearful of physiological arousal may be a particularly ‘at-risk’ population for smoking cessation difficulties due, in part, to greater perceived barriers to cessation. Interventions focused on enhancing intrinsic motivation for quitting and reducing AS may be most effective for this population.
