Smoking-specific experiential avoidance is related to the maintenance of cigarette smoking. However, it is unclear whether sustained smoking abstinence is associated with subsequent reductions in smoking-specific experiential avoidance.

Daily smokers (n = 149) underwent a cessation attempt in the context of a 4-session smoking cessation treatment trial. Participants provided biochemical verification of smoking status at 1 week, 2 weeks, and 1 Month post-quit day. Smoking-specific experiential avoidance was assessed per the Avoidance and Inflexibility Scale (AIS) - the total score and two factor scores were examined at 1 Month post-quit day as a function of abstinence status. Two path models were conducted and included participant sex, treatment condition, and pre-cessation nicotine dependence, smoking-specific experiential avoidance, and presence of emotional disorders as covariates.

After adjusting for covariates, sustained smoking abstinence was associated with a reduction in the AIS total score at Month 1 post-quit (β = -.45, p < .001). Sustained smoking abstinence was associated with reductions across both facets of experiential avoidance -- smoking-related thoughts and feelings (β = -.44, p < .001) and internal bodily sensations (β = -.41, p < .001).

Biochemical verification of smoking status was confirmed only at three time points post-quit day, and continued abstinence throughout the one-month post-quitting period is not fully known.

Sustained smoking abstinence may contribute to reductions in smoking-specific experiential avoidance. Findings add to the research documenting the relevance of experiential avoidance in various processes of smoking (including smoking abstinence).
