Abstract
We conducted a cross-sectional study, examining the mediation effects of depression and anxiety on the association between discrimination and readiness to quit cigarette smoking among African American adult cigarette smokers experiencing homelessness. Using a convenience sample, participants were recruited from a homeless shelter in Southern California. Scores of discrimination, depressive, and anxiety symptoms, and readiness to quit smoking were analyzed using linear regression modeling. We enrolled 100 participants; 58 participants were male. In the final model, discrimination had no association with readiness to quit (b = 0.02; 95% CI [-0.04, 0.08]; p = 0.47). The indirect effects of depression (b = 0.04, [0.01, 0.07]; p = 0.02) and anxiety (b = 0.03; [0.01, 0.05]; p = 0.04) reached statistical significance; the direct effects of depression (b = -0.01; [-0.09, 0.04]; p = 0.70) and anxiety (b = -0.00; [-0.09, 0.06]; p = 0.86) did not. Future studies should explore these associations to enhance smoking cessation programs for this population.

Abstract
Self-reports indicate that stress increases the risk for smoking; however, intensive data from sensors can provide a more nuanced understanding of stress in the moments leading up to and following smoking events. Identifying personalized dynamical models of stress-smoking responses can improve characterizations of smoking responses following stress, but techniques used to identify these models require intensive longitudinal data. This study leveraged advances in wearable sensing technology and digital markers of stress and smoking to identify person-specific models of stress and smoking system dynamics by considering stress immediately before, during, and after smoking events. Adult smokers (n = 45) wore the AutoSense chestband (respiration-inductive plethysmograph, electrocardiogram, accelerometer) with MotionSense (accelerometers, gyroscopes) on each wrist for three days prior to a quit attempt. The odds of minute-level smoking events were regressed on minute-level stress probabilities to identify person-specific dynamic models of smoking responses to stress. Simulated pulse responses to a continuous stress episode revealed a consistent pattern of increased odds of smoking either shortly after the beginning of the simulated stress episode or with a delay, for all participants. This pattern is followed by a dramatic reduction in the probability of smoking thereafter, for about half of the participants (49%). Sensor-detected stress probabilities indicate a vulnerability for smoking that may be used as a tailoring variable for just-in-time interventions to support quit attempts.
