Differences in smoking expectancies in smokers with and without a history of major depression.

ABSTRACT: Adults with depression evidence higher rates of smoking and lower quit rates than adults without depression. Little is known about the relationship between depression and smoking beliefs which are associated with both smoking and smoking cessation behavior. The primary aim of this study was to examine whether adult smokers with and without a history of major depressive disorder (MDD) differ in their endorsement of smoking expectancies. The secondary aim of the study was to examine whether there were interactions of depression and gender on the endorsement of expectancies. Adult cigarette smokers participating in a clinical trial of Selegiline hydrochloride for smoking cessation were classified as having a history of depression (MDD+, n=26) or no history of depression (MDD-, n=75). History of depression and smoking expectancies were assessed prior to randomization into the clinical trial. There was a main effect of depression on 7 out of 10 of the assessed beliefs. MDD+ smokers, compared to MDD- smokers, more strongly endorsed beliefs that smoking reduces negative affect, boredom, and cravings; smoking increases stimulation and social facilitation; smoking helps to manage cravings and weight; and that the taste is enjoyable. The main effect of gender and the interactive effect of depression and gender were not significant. Incorporating expectancies into cognitive-behavioral treatments for smoking cessation may be useful for smokers with a history of depression.

Project description:Cigarette smoking and traumatic life experiences are each common among homeless adults, but the prevalence and correlates of posttraumatic stress disorder (PTSD) symptoms among homeless smokers are not known. We assessed symptoms of PTSD and their association with smoking outcome expectancies in a sample of homeless smokers in Boston.We used time-location sampling to conduct an in-person survey of homeless adult smokers using Boston Health Care for the Homeless Program clinical services. We assessed symptoms of PTSD with the PTSD Checklist-Civilian version and considered scores at least 14 as positive. We used the Smoking Effects Questionnaire to assess positive and negative smoking outcome expectancies. We modeled the associations between PTSD screening status and smoking expectancies using design-adjusted linear regression.Eighty-six percent of eligible individuals participated (N = 306). Sixty-eight percent of participants screened positive for PTSD. Screen-positive respondents were younger (P = .001), more likely to report fair/poor health (P = .01), chronic obstructive pulmonary disease (P = .02), and past-month hallucinations (P = .004), and had greater drug (P < .001) and alcohol (P < .001) use severity and cigarette dependence (P = .002). In analyses controlling for these confounders, PTSD screen-positive participants more strongly endorsed smoking to reduce negative affect (P = .01), smoking for social benefits (P = .002), and smoking for weight control (P = .03). Exploratory analyses suggested that these associations were driven by avoidance/numbing and re-experiencing symptoms.Symptoms of posttraumatic stress are common among homeless smokers and strongly associated with positive smoking outcome expectancies. Tobacco cessation programs for this population should consider screening for PTSD and fostering a trauma-sensitive treatment environment.In this study of homeless cigarette smokers in Boston, over two-thirds of participants screened positive for PTSD. PTSD screen-positive respondents more strongly endorsed multiple positive smoking outcome expectancies than screen-negative individuals. These findings suggest that the psychological sequelae of trauma may be a pervasive but under-recognized factor impacting the persistence of smoking among homeless people. Tobacco cessation programs for this population should consider screening for PTSD, fostering a trauma-sensitive treatment environment, and incorporating strategies that have shown promise in smokers with PTSD.

Project description:IntroductionIndividuals with serious mental illness (SMI) smoke at rates two to three times greater than the general population but are less likely to receive treatment. Increasing our understanding of correlates of smoking cessation behaviors in this group can guide intervention development.Aims and methodsBaseline data from an ongoing trial involving smokers with SMI (N = 482) were used to describe smoking cessation behaviors (ie, quit attempts, quit motivation, and smoking cessation treatment) and correlates of these behaviors (ie, demographics, attitudinal and systems-related variables).ResultsForty-three percent of the sample did not report making a quit attempt in the last year, but 44% reported making one to six quit attempts; 43% and 20%, respectively, reported wanting to quit within the next 6 months or the next 30 days. Sixty-one percent used a smoking cessation medication during their quit attempt, while 13% utilized counseling. More quit attempts were associated with lower nicotine dependence and carbon monoxide and greater beliefs about the harms of smoking. Greater quit motivation was associated with lower carbon monoxide, minority race, benefits of cessation counseling, and importance of counseling within the clinic. A greater likelihood of using smoking cessation medications was associated with being female, smoking more cigarettes, and receiving smoking cessation advice. A greater likelihood of using smoking cessation counseling was associated with being male, greater academic achievement, and receiving smoking cessation advice.ConclusionsMany smokers with SMI are engaged in efforts to quit smoking. Measures of smoking cessation behavior are associated with tobacco use indicators, beliefs about smoking, race and gender, and receiving cessation advice.ImplicationsConsideration of factors related to cessation behaviors among smokers with SMI continues to be warranted, due to their high smoking rates compared to the general population. Increasing our understanding of these predictive characteristics can help promote higher engagement in evidence-based smoking cessation treatments among this subpopulation.
