Smoking outcome expectancies in military veteran smokers with posttraumatic stress disorder.

ABSTRACT: INTRODUCTION:Smoking outcome expectancies were investigated in treatment-seeking military Veteran smokers with posttraumatic stress disorder (PTSD). The investigation of smoking outcome expectancies may enhance our understanding of the relationship between PTSD and cigarette smoking. METHODS:Participants were 943 military Veterans with a diagnosis of PTSD who were current smokers enrolled in a randomized multisite effectiveness trial to test whether the integration of smoking cessation treatment into mental health care (integrated care) improves prolonged abstinence rates compared with referral to specialized smoking cessation clinics (usual care). Using confirmatory factor analysis (CFA), we evaluated the conceptual model of smoking outcome expectancies measured on the Smoking Consequences Questionnaire-Adult (SCQ-A) version. The Kraemer method of mediation analysis was used to investigate the role of smoking outcome expectancies in mediating relationships between PTSD symptoms and smoking behavior, tobacco dependence, and abstinence self-efficacy. RESULTS:The CFA supported the 10-factor structure of the SCQ-A in smokers with PTSD. Relationships between measures of PTSD symptoms and tobacco dependence were mediated by the smoking outcome expectancy regarding negative affect reduction. This same smoking outcome expectancy mediated relationships between PTSD symptoms and smoking abstinence self-efficacy. CONCLUSIONS:The findings support the use of the SCQ-A as a valid measure of smoking outcome expectancies in military Veteran smokers with PTSD. Moreover, they suggest that smoking outcome expectancies may play an important role in explaining the relationship between PTSD and cigarette smoking.

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:IntroductionThe high smoking prevalence amongst individuals with psychiatric disorders constitutes a major public health disparity. Negative reinforcement models of addiction posit that severe tobacco withdrawal symptoms, related to the affective vulnerabilities of these smokers, may thwart their quitting smoking successfully. However, relatively few studies have prospectively examined the effects of nicotine deprivation on withdrawal symptoms in these groups.MethodsThis study compared the level of withdrawal symptoms both before and after nicotine deprivation in those diagnosed with posttraumatic stress disorder (PTSD) or major depressive disorder (MDD) and in those without psychiatric diagnoses. Participants were US veterans who smoked (≥10 cigarettes/day) and met diagnostic criteria for PTSD (n = 38), MDD (n = 43), or no psychiatric diagnosis ("controls" n = 44). Participants attended study visits before and during 48-hour nicotine deprivation to report tobacco withdrawal symptoms. Analyses evaluated withdrawal symptom levels (baseline and during nicotine deprivation) and the change in symptoms related to nicotine deprivation and compared (1) participants with a psychiatric diagnosis versus controls, and (2) participants with PTSD versus MDD.ResultsContrary to hypotheses, nicotine deprivation produced greater increases in most withdrawal symptoms amongst controls than in those with psychiatric diagnoses. Compared with controls, those with PTSD or MDD reported elevated symptom levels both before and after tobacco deprivation for most withdrawal symptoms.ConclusionsThese findings suggest that chronically high levels of distress and craving, rather than acute increases in withdrawal symptoms because of nicotine deprivation, may account for the quitting difficulties of those with comorbid conditions such as PTSD and MDD.ImplicationsSevere tobacco withdrawal may account for the higher quitting difficulties of smokers with either posttraumatic stress disorder (PTSD) or major depressive disorder (MDD). Paradoxically, this study showed that individuals with no psychiatric diagnosis had greater increases in tobacco withdrawal severity because of nicotine deprivation than did those with either PTSD or MDD. Those with either PTSD or MDD showed high stable levels of withdrawal symptom severity both before and during two days of abstinence, suggesting that their quitting difficulties may be related to their chronically high levels of distress rather than nicotine deprivation per se.

Project description:BackgroundMilitary-related posttraumatic stress disorder (PTSD) is a complex diagnosis with non-linear trajectories of coping and recovery. Current approaches to the evaluation of PTSD and treatment discontinuation often rely on biomedical models that dichotomize recovery based on symptom thresholds. This approach may not sufficiently capture the complex lived experiences of Veterans and their families. To explore conceptualizations of recovery, we sought perspectives from Veterans and their partners in a pilot study to understand: 1) how Veterans nearing completion of treatment for military-related PTSD and their partners view recovery; and 2) the experience of progressing through treatment towards recovery.MethodsWe employed a concurrent mixed methods design. Nine Veterans nearing the end of their treatment at a specialized outpatient mental health clinic completed quantitative self-report tools assessing PTSD and depressive symptom severity, and an individual, semi-structured interview assessing views on their treatment and recovery processes. Veterans' partners participated in a separate interview to capture views of their partners' treatment and recovery processes. Descriptive analyses of self-report symptom severity data were interpreted alongside emergent themes arising from inductive content analysis of qualitative interviews.ResultsWhile over half of Veterans were considered "recovered" based on quantitative assessments of symptoms, individual reflections of "recovery" were not always aligned with these quantitative assessments. A persistent narrative highlighted by participants was that recovery from military-related PTSD was not viewed as a binary outcome (i.e., recovered vs. not recovered); rather, recovery was seen as a dynamic, non-linear process. Key components of the recovery process identified by participants included a positive therapeutic relationship, social support networks, and a toolkit of adaptive strategies to address PTSD symptoms.ConclusionsFor participants in our study, recovery was seen as the ability to navigate ongoing issues of symptom management, re-engagement with meaningful roles and social networks, and a readiness for discontinuing intensive, specialized mental health treatment. The findings of this study highlight important considerations in balancing the practical utility of symptom severity assessments with a better understanding of the treatment discontinuation-related needs of Veterans with military-related PTSD and their families, which align with a contemporary biopsychosocial approach to recovery.
