Abstract

Abstract: Objective: We tested whether mindfulness de-couples the expected anxiogenic effects of distress intolerance on psychological and physiological reactivity to and recovery from an anxiogenic stressor among participants experimentally sensitized to experience distress. Method: N = 104 daily smokers underwent 18-hours of biochemically-verified smoking deprivation. Participants were then randomized to a 7-min analogue mindfulness intervention (present moment attention and awareness training; PMAA) or a cope-as-usual control condition; and subsequently exposed to a 2.5-min paced over breathing (hyperventilation) stressor designed to elicit acute anxious arousal. Psychological and physiological indices of anxious arousal (Skin Conductance Levels; SCL) as well as emotion (dys)regulation (Respiratory Sinus Arrhythmia; RSA) were measured before, during and following the stressor. Results: We found that PMAA reduced psycho-physiological dysregulation in response to an anxiogenic stressor, as well as moderated the anxiogenic effect of distress intolerance on psychological but not physiological responding to the stressor among smokers pre-disposed to experience distress via deprivation. Conclusions: The present study findings have a number of theoretical and clinical implications for work on mindfulness mechanisms, distress tolerance, emotion regulation, and smoking cessation interventions. Highlights: Brief mindfulness meditation buffers the anxiogenic effects of distress intolerance among deprived smokers exposed to stress. Brief mindfulness meditation improves physiological regulation of anxious arousal elicited by stress. Findings relevant to mindfulness intervention and mechanisms research as well as smoking cessation intervention research.
