Differences in Distress Intolerance Among Daily and Intermittent Smokers.

Abstract

Distress intolerance is an important risk factor for smokers. Smokers have greater problems tolerating distress than nonsmokers, and distress intolerance is theoretically an important predictor of early lapse. However, much of the distress intolerance research has been conducted on daily smokers. Understanding distress intolerance in nondaily or intermittent smokers may help elucidate whether distress intolerance is a function of current smoking habits. Daily (n = 36) and intermittent (n = 28) smokers completed behavioral distress intolerance tasks (breath holding, mirror tracing persistence, and image persistence) along with self-report measures of both general and smoking-specific distress intolerance. They also completed 1 week of ecological momentary assessment where positive and negative affect were assessed along with momentary distress intolerance, at both random times (7×/day) and immediately prior to smoking a cigarette. Results found no differences between intermittent and daily smokers on behavioral distress intolerance tasks or general self-reported distress intolerance. Daily smokers reported greater self-reported smoking-specific distress intolerance compared to intermittent smokers. In addition, across both smoker groups, momentary distress intolerance was higher at smoking compared to random sessions, and low positive affect predicted greater momentary distress intolerance specifically for intermittent smokers prior to smoking. The lack of differences between daily and intermittent smokers on general distress intolerance measures suggests that distress intolerance abilities and self-perceptions are not a function of higher levels of current smoking. However, the contextual variation in momentary distress intolerance is worth further exploration in both daily and intermittent smokers. The overall lack of differences between intermittent and daily smokers on distress intolerance tasks and self-report measures suggests that daily smoking is not associated with lower abilities to manage or tolerate distress at the individual difference level. However, understanding fluctuations in distress intolerance across time and context is crucial, as smokers' perceptions of their abilities to manage distress shift based on affect and smoking contexts. Stabilizing or increasing self-efficacy in tolerating distress during daily life is likely an important avenue for future research.
