Objective: Based on conceptual models of addiction and affect regulation, this study examined the mechanisms linking current major depressive syndrome (MDS) and anxiety syndrome (AS) to postpartum smoking relapse. Method: Data were collected in a randomized clinical trial from 251 women who quit smoking during pregnancy. Simple and multiple mediation models of the relations of MDS and AS with postpartum relapse were examined using linear regression, continuation ratio logit models, and a bootstrapping procedure to test the indirect effects. Results: Both MDS and AS significantly predicted postpartum smoking relapse. After adjusting for MDS, AS significantly predicted relapse. However, after adjusting for AS, MDS no longer predicted relapse. Situationally based self-efficacy, expectancies of controlling negative affect by means other than smoking, and various dimensions of primary and secondary tobacco dependence individually mediated the effect of both MDS and AS on relapse. In multiple mediation models, self-efficacy in negative/affective situations significantly mediated the effect of MDS and AS on relapse. Conclusions: The findings underscore the negative impact of depression and anxiety on postpartum smoking relapse and suggest that the effects of MDS on postpartum relapse may be largely explained by comorbid AS. The current investigation provided mixed support for affect regulation models of addiction. Cognitive and tobacco dependence-related aspects of negative and positive reinforcement significantly mediated the relationship of depression and anxiety with relapse, whereas affect and stress did not. The findings emphasize the unique role of low agency with respect to abstaining from smoking in negative affective situations as a key predictor of postpartum smoking relapse.

Objectives. We evaluated the influence of financial strain on smoking cessation among Latino, African American, and Caucasian smokers of predominantly low socioeconomic status. Methods. Smokers enrolled in a smoking cessation study (N=424) were followed from 1 week prequit through 26 weeks postquit. We conducted a logistic regression analysis to evaluate the association between baseline financial strain and smoking abstinence at 26 weeks postquit after control for age, gender, race/ ethnicity, educational level, annual household income, marital status, number of cigarettes smoked per day, and time to first cigarette of the day. Results. Greater financial strain at baseline was significantly associated with reduced odds of abstinence at 26 weeks postquit among those who completed the study (odds ratio [OR]=0.77; 95% confidence interval [CI] =0.62, 0.94; P=.01). There was a significant association as well in analyses that included those who completed the study in addition to those lost to follow-up who were categorized as smokers (OR=0.78; 95% CI=0.64, 0.96; P=.02). Conclusions. Greater financial strain predicted lower cessation rates among racially/ethnically diverse smokers. Our findings highlight the impact of economic concerns on smoking cessation and the need to address financial strain in smoking cessation interventions.

Background: Inhaled medications are recommended as first-line treatment for chronic obstructive pulmonary disease (COPD) and can reduce exacerbations and hospitalizations. Low health literacy is associated with poor inhaler technique. Objective: This study examined whether handouts written specifically for patients with low health literacy are more effective in showing patients how to use their medications when compared to standard education materials. Methods: A prospective, experimental study was performed at a community-based hospital. Patients included in the study were admitted to the hospital with a diagnosis of COPD, taking at least 1 inhaled medication and identified as having low health literacy based on a Rapid Estimate of Adult Literacy in Medicine—Short Form. Low health literacy handouts were compared against the standard hospital educational materials for inhalers. Correct technique during each demonstration was evaluated using a standardized checklist. Results: Mean baseline scores for inhaler technique were 12.2 ± 2.2 steps correct for the control group and 13.4 ± 1.3 for the low health-literacy group of the 18 maximum points (P = nonsignificant). The mean change in inhaler technique score for the control group was 1.0 ± 1.8, while the mean change in inhaler technique score for the low health-literacy group was 2.1 ± 2.7 (P = .03).
