Stress plays a significant role in the maintenance of, and relapse to, smoking. The current study aims to develop a human laboratory model examining stress-precipitated tobacco lapse following brief nicotine deprivation. Daily smokers (N = 48; 50% female) who were nicotine deprived for 3 hr received a personalized imagery induction (stress or neutral, within-subject, counterbalanced) on 2 separate days. Following imagery induction, participants were instructed that they could smoke or receive monetary reinforcement ($0.25, $0.50, $1.00; between-subjects) for every 5 min they chose to delay tobacco self-administration during a 50-min delay period. After the delay period, participants engaged in a 1-hr ad libitum smoking period. Tobacco craving and mood were assessed throughout. The primary aim was to determine whether stress imagery would reduce the ability to resist following a brief nicotine deprivation in a laboratory setting. A secondary goal identified which level of monetary reinforcement highlighted the effect of stress on reduced ability to resist smoking (i.e., resisting ∼25 min of the 50-min window). Overall, stress versus neutral imagery decreased the ability to resist smoking, increased craving and negative mood states, decreased positive mood, but did not change ad libitum smoking. Increased monetary reinforcement increased the ability to resist smoking. Planned comparisons examining lapse behavior within each monetary condition demonstrated that $0.50 produced the only significant difference between stress and neutral imagery, demonstrating target model behavior. Findings highlight that stress negatively impacts smoking lapse behavior and can be effectively modeled in the human laboratory with a brief, 3-hr deprivation window. (PsycINFO Database Record
