Improving the rates of quitting smoking for veterans with posttraumatic stress disorder

Trauma exposure and smoking outcomes: The indirect effects of anxious and depressive symptoms

With a direct link between traumatic stress and poor smoking outcomes established, there is a clinically important need to identify underlying, targetable mechanisms that maintain these relations. The present study employed a parallel mediation model to assess the competing explanatory significance of four distinct facets of depression and anxiety (general anxiety, anxious arousal, general depression, and anhedonic depression) in the relation between traumatic load and perceived barriers for quitting smoking, severity of psychosomatic problems experienced when attempting to quit smoking in the past, and negative reinforcement expectancies related to smoking among 98 adult trauma-exposed daily smokers (Mage = 44.64, SD = 10.66). Results showed that only general anxiety symptoms, when controlling for the competing facets of depression and anxiety, had a statistically significant indirect effect on the relation between traumatic load and all smoking processes, such that general anxiety symptoms significantly, indirectly influenced the relation between traumatic load and barriers for smoking cessation (ab = 0.95, 95% CI [0.163, 0.2.14]), smoking quit problems (ab = 0.07, 95% CI [0.009, 0.165]), and negative reinforcement smoking expectancies (ab = 0.16, 95% CI [0.025, 0.399]). Anxious arousal demonstrated an indirect effect for trauma load on only negative reinforcement smoking expectancies (ab = -0.15, 95% CI [-0.345, -0.023]). The current findings highlight the potential importance of general anxiety symptoms as a targetable mechanism for smoking cessation treatments for trauma-exposed smokers.

The Relationship Between Trauma Exposure and Adult Tobacco Use: Analysis of the National Epidemiologic Survey on Alcohol and Related Conditions (III)

INTRODUCTION

Previous research has examined cigarette smoking in trauma exposed populations. However, the relationships between trauma exposure and use of other tobacco products (eg, cigars, e-cigarettes) and specific trauma exposure characteristics that may be associated with tobacco use are understudied.

AIMS AND METHODS

Using the 2012-2013 National Epidemiologic Survey on Alcohol and Related Conditions-III (N = 36 151 adults), we conducted weighted bivariate analyses of tobacco use among participants with no trauma exposure, trauma exposure, and trauma exposure with post-traumatic stress disorder (trauma + PTSD), stratified by tobacco product use. We also performed weighted logistic regressions testing relationships between trauma exposure and tobacco use, controlling for behavioral health (BH) conditions (mood, anxiety, substance use, personality disorders) and sociodemographics.

RESULTS

Approximately 44% of participants had experienced trauma; 6% experienced trauma + PTSD. Trauma exposed participants had a higher prevalence of tobacco use (30%--46% vs. 22%) and poly-tobacco use (34%--35% vs. 28%) than unexposed participants. Cigarettes were the most used tobacco product; trauma + PTSD (19%), and trauma (15%) participants had a higher prevalence of e-cigarette use than unexposed participants (11%). Trauma exposure was associated with current tobacco use (AOR = 1.36 trauma + PTSD; 1.23 trauma) (but not former use), particularly among participants exposed to violence/abuse (AOR = 1.23). Personality and substance use disorders were strongly associated with current and former tobacco use.

CONCLUSIONS

Trauma exposure, PTSD, and experiences of violence/abuse are associated with current tobacco use. BH conditions may also play a role in current and former tobacco use. Recognizing and addressing trauma exposure and BH conditions among tobacco users may improve cessation rates in these populations.

IMPLICATIONS

This study contributes to research on tobacco use disparities in behavioral health populations by providing a comprehensive examination of tobacco use in trauma exposed individuals. Prior research has examined cigarette smoking, but not other tobacco product use in these populations. This study presents findings on multiple tobacco use behaviors (tobacco product, poly-tobacco use, cessation attempts) in trauma exposed populations and characteristics of trauma exposure (severity, type of traumatic event) associated with tobacco use. These findings underscore the importance of further examining the implications of trauma exposure for tobacco use and of screening and addressing trauma in cessation treatment.

Interventions for adults with a history of complex traumatic events: the INCiTE mixed-methods systematic review

BACKGROUND

People with a history of complex traumatic events typically experience trauma and stressor disorders and additional mental comorbidities. It is not known if existing evidence-based treatments are effective and acceptable for this group of people.

OBJECTIVE

To identify candidate psychological and non-pharmacological treatments for future research.

DESIGN

Mixed-methods systematic review.

PARTICIPANTS

Adults aged ≥ 18 years with a history of complex traumatic events.

INTERVENTIONS

Psychological interventions versus control or active control; pharmacological interventions versus placebo.

MAIN OUTCOME MEASURES

Post-traumatic stress disorder symptoms, common mental health problems and attrition.

DATA SOURCES

Cumulative Index to Nursing and Allied Health Literature (CINAHL) (1937 onwards); Cochrane Central Register of Controlled Trials (CENTRAL) (from inception); EMBASE (1974 to 2017 week 16); International Pharmaceutical Abstracts (1970 onwards); MEDLINE and MEDLINE Epub Ahead of Print and In-Process & Other Non-Indexed Citations (1946 to present); Published International Literature on Traumatic Stress (PILOTS) (1987 onwards); PsycINFO (1806 to April week 2 2017); and Science Citation Index (1900 onwards). Searches were conducted between April and August 2017.

REVIEW METHODS

Eligible studies were singly screened and disagreements were resolved at consensus meetings. The risk of bias was assessed using the Cochrane risk-of-bias tool and a bespoke version of a quality appraisal checklist used by the National Institute for Health and Care Excellence. A meta-analysis was conducted across all populations for each intervention category and for population subgroups. Moderators of effectiveness were assessed using metaregression and a component network meta-analysis. A qualitative synthesis was undertaken to summarise the acceptability of interventions with the relevance of findings assessed by the GRADE-CERQual checklist.

RESULTS

One hundred and four randomised controlled trials and nine non-randomised controlled trials were included. For the qualitative acceptability review, 4324 records were identified and nine studies were included. The population subgroups were veterans, childhood sexual abuse victims, war affected, refugees and domestic violence victims. Psychological interventions were superior to the control post treatment for reducing post-traumatic stress disorder symptoms (standardised mean difference -0.90, 95% confidence interval -1.14 to -0.66; number of trials = 39) and also for associated symptoms of depression, but not anxiety. Trauma-focused therapies were the most effective interventions across all populations for post-traumatic stress disorder and depression. Multicomponent and trauma-focused interventions were effective for negative self-concept. Phase-based approaches were also superior to the control for post-traumatic stress disorder and depression and showed the most benefit for managing emotional dysregulation and interpersonal problems. Only antipsychotic medication was effective for reducing post-traumatic stress disorder symptoms; medications were not effective for mental comorbidities. Eight qualitative studies were included. Interventions were more acceptable if service users could identify benefits and if they were delivered in ways that accommodated their personal and social needs.

LIMITATIONS

Assessments about long-term effectiveness of interventions were not possible. Studies that included outcomes related to comorbid psychiatric states, such as borderline personality disorder, and populations from prisons and humanitarian crises were under-represented.

CONCLUSIONS

Evidence-based psychological interventions are effective and acceptable post treatment for reducing post-traumatic stress disorder symptoms and depression and anxiety in people with complex trauma. These interventions were less effective in veterans and had less of an impact on symptoms associated with complex post-traumatic stress disorder.

FUTURE WORK

Definitive trials of phase-based versus non-phase-based interventions with long-term follow-up for post-traumatic stress disorder and associated mental comorbidities.

The effectiveness of interventions to increase preventive care provision for chronic disease risk behaviours in mental health settings: A systematic review and meta-analysis

Clinical practice guidelines direct mental health services to provide preventive care to address client chronic disease risk behaviours, however, this care is not routinely provided. The aim of this systematic review was to synthesise evidence regarding the effectiveness of interventions to increase provision of preventive care by mental health services; by care element (ask, assess, advice, assist, arrange) and risk behaviour (tobacco smoking, poor nutrition, harmful alcohol consumption, physical inactivity). Electronic bibliographic databases, Google Scholar, relevant journals, and included study reference lists were searched. Eligible studies were of any design with a comparison group that reported the effectiveness of an intervention to increase the provision of at least one element of preventive care for at least one risk behaviour in a mental health setting. Twenty studies were included, most commonly examining smoking (n = 20) and 'ask' (n = 12). Meta-analysis found interventions involving task shifting were effective in increasing smoking 'advice' (n = 2 RCTs; p = 0.009) and physical activity 'advice' (n = 2 RCTs; p = 0.002). Overall, meta-analysis and narrative synthesis indicated that effective intervention strategies (categorised according to the Effective Practice and Organisation of Care taxonomy) were: task shifting, educational meetings, health information systems, local consensus processes, authority and accountability, and reminders. The most consistent findings across studies were with regard to preventive care for smoking, while conflicting or limited evidence was found regarding other risk behaviours. While further rigorous research examining key risk behaviours is recommended, the findings may inform the selection of strategies for future interventions and service delivery initiatives.

Posttraumatic Stress Disorder in the Primary Care Setting: Summary of Recommended Care

Posttraumatic stress disorder (PTSD) occurs following acute threatening events in approximately 12.5% of the primary care population.

OBJECTIVE

The aim of this article is to advance evidence-based clinical practice and collaborative care approaches to PTSD by summarizing targeted-care guidelines.

METHOD

This narrative literature review addresses important aspects of PTSD and management options, in conjunction with expert opinion when indicated. Guidelines were included if they targeted treatment of PTSD in the primary care setting or if the treatments described could be provided in the primary care setting.

RESULTS

The implications regarding PTSD, comorbidities, differential diagnosis, screening tools, and treatment are presented.

CONCLUSION

Primary care providers can diagnose and offer initial management of PTSD. Future research should delineate therapies helpful for complex PTSD, including group therapies, those increasing self-compassion, and other optimally effective collaborative care interventions.

A longitudinal analysis of tobacco use in younger and older U.S. veterans

United States (U.S.) veterans are prone to higher rates of smoking and smoking-related disease. We describe the prevalence of cigarette and non-cigarette product use and determine longitudinal predictors of tobacco use transitions in this vulnerable population.

Data are from Waves 1 (2013–2014) and 2 (2014–2015) of the adult cohort in the Population Assessment of Tobacco and Health. Wave 1 prevalence was calculated for past 30-day use of all queried tobacco products, and compared by veteran status. Weighted multinomial logistic regression was used to determine predictors—demographics, substance use, and physical and psychological comorbidities—of tobacco use transitions (continued use, initiation, and cessation) among veterans.

Compared to non-veterans, use of nearly all tobacco products was significantly higher among veterans and was highest among younger veterans. Compared to continued nonusers, continued users were more likely to: be of younger age (OR = 0.95, 95% CI: 0.95–0.96), have poorer physical health (OR = 1.58, 95% CI: 1.22–2.06) and mental health (OR = 1.48, 95% CI: 1.18–1.85), report substance use (OR = 1.79, 95% CI: 1.21–2.64), and report problematic alcohol use (OR = 4.23, 95% CI: 2.38–7.52) and were less likely to be female (OR = 0.57, 95% CI: 0.35–0.93). Compared to continued nonusers, initiators were more likely to report problematic alcohol use (OR = 8.63, 95% CI: 3.79–19.63), and those in the cessation category were more likely to be of younger age (OR = 0.97, 95% CI: 0.95–0.99).

Cigarette and non-cigarette use is especially prevalent among young veterans, so prevention should begin during military service. Tobacco cessation programs should be tailored for this population, incorporating aspects related to concomitant health conditions.

Integrating NIMH Research Domain Criteria (RDoC) into PTSD Research

Three and a half decades of research on posttraumatic stress disorder (PTSD) has produced substantial knowledge on the pathobiology of this frequent and debilitating disease. However, despite all research efforts, so far no drug that has specifically targeted PTSD core symptoms progressed to clinical use. Instead, although not overly efficient, serotonin re-uptake inhibitors continue to be considered the gold standard of PTSD pharmacotherapy. The psychotherapeutic treatment and symptom-oriented drug therapy options available for PTSD treatment today show some efficacy, although not in all PTSD patients, in particular not in a substantial percent of those suffering from the detrimental sequelae of repeated childhood trauma or in veterans with combat related PTSD. PTSD has this in common with other psychiatric disorders - in particular effective treatment for incapacitating conditions such as resistant major depression, chronic schizophrenia, and frequently relapsing obsessive-compulsive disorder as well as dementia has not yet been developed through modern neuropsychiatric research.In response to this conundrum, the National Institute of Mental Health launched the Research Domain Criteria (RDoC) framework which aims to leave diagnosis-oriented psychiatric research behind and to move on to the use of research domains overarching the traditional diagnosis systems. To the best of our knowledge, the paper at hand is the first that has systematically assessed the utility of the RDoC system for PTSD research. Here, we review core findings in neurobiological PTSD research and match them to the RDoC research domains and units of analysis. Our synthesis reveals that several core findings in PTSD such as amygdala overactivity have been linked to all RDoC domains without further specification of their distinct role in the pathophysiological pathways associated with these domains. This circumstance indicates that the elucidation of the cellular and molecular processes ultimately decisive for regulation of psychic processes and for the expression of psychopathological symptoms is still grossly incomplete. All in all, we find the RDoC research domains to be useful but not sufficient for PTSD research. Hence, we suggest adding two novel domains, namely stress and emotional regulation and maintenance of consciousness. As both of these domains play a role in various if not in all psychiatric diseases, we judge them to be useful not only for PTSD research but also for psychiatric research in general.

Posttraumatic stress disorder and cigarette smoking: A systematic review

BACKGROUND

Previous reviews of the PTSD and cigarette smoking literature showed high PTSD-smoking comorbidity and problematic smoking outcomes (Feldner et al., 2007, Clinical Psychology Review, 27, 14-45; Fu et al., 2007, Nicotine & Tobacco Research, 9, 1071-1084). However, past reviews also noted several prominent gaps in the literature, including a lack of etiological work examining underlying mechanisms and research on specialized PTSD-smoking treatments. The present review summarizes an extensive body of research conducted since the previous reviews targeting these areas of need.

METHODS

Literature searches identified 66 empirical studies specific to smoking and PTSD.

RESULTS

Smokers were approximately twice more likely to have PTSD than nonsmokers in the general population, and individuals with PTSD were approximately twice as likely to be current smokers. Smokers with PTSD evidenced more negative affect, trauma history, and comorbid psychiatric history, as well as quit attempts and higher relapse rates. PTSD symptoms were associated with expectations that smoking would reduce negative affect, which, in turn, was associated with increased smoking rate and nicotine dependence. Male sex was associated with nicotine dependence and PTSD avoidance, while the relationship between PTSD and smoking relapse due to withdrawal was stronger in females. Specialized, integrated PTSD and smoking cessation treatments showed promise in increasing quit success relative to standard care in randomized trials.

CONCLUSIONS

Rates of PTSD-smoking co-occurrence remain high. Notable gains have been made in relevant epidemiological and etiological research, although more work is needed in trauma-specific subpopulations. Several promising specialized treatments for comorbid smoking-PTSD have been developed and empirically tested but require replication.

From Policy to Practice: Tobacco Use Cessation for Employees in the Veterans Health Administration

OBJECTIVE

To describe a comprehensive approach to increase tobacco use cessation in the Veterans Health Administration (VHA) employee population.

METHODS

The approach included: 1) national policy; 2) a pilot tobacco use cessation program; and 3) two operational surveys to assess system-wide tobacco use cessation service provision.

RESULTS

The proportion of VHA facilities offering a comprehensive tobacco use cessation program increased from 51% in 2010 to 72% in 2014, with 83% of facilities providing nicotine replacement therapy to employees. The WIN by Quitting Tobacco program was successful; employees who participated in the pilot program quit tobacco at high rates (64% at 1 month post quit date).

CONCLUSIONS

From policy to practice, the comprehensive approach to tobacco use cessation in VHA was successful and may serve as a model for future workplace health promotion and occupational safety and health initiatives.

A Learning Collaborative Model for Implementation of Smoking Cessation among Homeless Veterans

We evaluated the feasibility of incorporating integrated care (IC) for smoking cessation into routine care for homeless veterans at seven Department of Veterans Affairs (VA) Medical Centers and the utility of the learning collaborative (LC) model in facilitating implementation. The goal of IC is for clinicians to provide smoking cessation concurrent with other clinical duties. The LC model utilises multidisciplinary teams and recognised field experts to develop methods for accelerating the use of evidence-based treatments. Multidisciplinary teams comprising 34 (of about 175) staff members from seven VA homeless provider teams participated. Via self-report questionnaires, we assessed providers’ perceptions of the LC and the number of providers delivering IC. Nineteen of thirty-four providers (54%) reported delivering IC at the end of training and at 10-months. Providers rated the face-to-face trainings and collaborative team trainings as the most helpful LC components. Barriers to the use of the LC included lack of leadership support and the lack of ability to electronically track progress through the electronic medical record. Additional research, quality improvement, and policy changes at higher administrative levels are needed to identify methods to sustain the use of LC among providers serving homeless veterans.

Concurrent varenicline and prolonged exposure for patients with nicotine dependence and PTSD: A randomized controlled trial

BACKGROUND

Prevalence of smoking among individuals with posttraumatic stress disorder (PTSD) is disproportionately high, and PTSD is associated with especially poor response to smoking cessation treatment.

OBJECTIVE

The current study examined whether integrating treatments for smoking cessation (varenicline plus smoking cessation counseling; VARCC) and PTSD (prolonged exposure therapy; PE) enhances smoking outcomes among smokers diagnosed with PTSD.

METHOD

142 adults with nicotine dependence (ND) and PTSD were randomized to a treatment program consisting of varenicline, smoking cessation counseling, and PE (VARCC + PE) or to VARCC only. Seven-day point prevalence abstinence (PPA) at posttreatment (3-months postquit day) and follow-up (6-months postquit day), verified by serum cotinine levels and exhaled carbon monoxide, was the primary smoking outcome. Psychological outcomes were PTSD and depression severity. Mixed effects models included baseline PTSD severity as a moderator of treatment condition effects.

RESULTS

Overall, VARCC + PE participants did not show greater PPA than VARCC participants. However, treatment effects were moderated by baseline PTSD severity. For participants with moderate and high PTSD severity, VARCC + PE led to significantly higher PPA than VARCC alone (ps<.05). No differences between treatment conditions emerged for participants with low baseline PTSD severity. Participants who received PE showed significantly greater reduction of PTSD and depression symptoms than those who did not receive PE.

CONCLUSIONS

Integrating psychological treatment for PTSD and smoking cessation treatment enhances smoking cessation for participants with moderate or severe PTSD symptom severity, but does not enhance smoking cessation for participants with low baseline PTSD severity. (PsycINFO Database Record

Panic attack history and smoking topography

BACKGROUND

Little is known about panic attacks and puffing topography, a behavioral index of the value of smoking reinforcement. This study examined smoking style during the course of smoking of a single cigarette among adult daily smokers with and without a history of panic attacks.

METHOD

Participants (n=124, M_age=43.9, SD=9.7; 44.4% female) were non-treatment seeking daily smokers. Lifetime panic attack history was assessed via diagnostic assessment; 28.2% (n=35) of the sample had a panic attack history. Participants smoked one cigarette during an ad libitum smoking trial. Puff volume, duration, and inter-puff interval were measured using the Clinical Research Support System (CReSS) pocket device.

RESULTS

Regression analyses revealed that panic attack status was not associated with significant differences in average puff volume, duration, or inter-puff interval. Multi-level modeling was used to examine puffing trajectories. Puff-level data revealed that there was a significant quadratic time x panic effect for puff volume and duration. Those with a panic attack history demonstrated relatively sustained levels of both puff volume and duration over time, whereas those without a history of panic attacks demonstrated an increase followed by a decrease in volume and duration over time. These effects were not accounted for by the presence of general psychopathology.

DISCUSSION

Smokers with a panic attack history demonstrate more persistent efforts to self-regulate the delivery of nicotine, and thus may be at risk for continued smoking and dependence. Tailored treatment may be needed to address unique vulnerabilities among this group.

Toward precision smoking cessation treatment I: Moderator results from a factorial experiment

BACKGROUND

The development of tobacco use treatments that are effective for all smokers is critical to improving clinical and public health. The Multiphase Optimization Strategy (MOST) uses highly efficient factorial experiments to evaluate multiple intervention components for possible inclusion in an optimized tobacco use treatment. Factorial experiments permit analyses of the influence of patient characteristics on main and interaction effects of multiple, relatively discrete, intervention components. This study examined whether person-factor and smoking characteristics moderated the main or interactive effects of intervention components on 26-week self-reported abstinence rates.

METHODS

This fractional factorial experiment evaluated six smoking cessation intervention components among primary care patients (N=637): Prequit Nicotine Patch vs. None, Prequit Nicotine Gum vs. None, Preparation Counseling vs. None, Intensive Cessation In-Person Counseling vs. Minimal, Intensive Cessation Telephone Counseling vs. Minimal, and 16 vs. 8 Weeks of Combination Nicotine Replacement Therapy (NRT; nicotine patch+nicotine gum).

RESULTS

Both psychiatric history and smoking heaviness moderated intervention component effects. In comparison with participants with no self-reported history of a psychiatric disorder, those with a positive history showed better response to 16- vs. 8-weeks of combination NRT, but a poorer response to counseling interventions. Also, in contrast to light smokers, heavier smokers showed a poorer response to counseling interventions.

CONCLUSIONS

Heavy smokers and those with psychiatric histories demonstrated a differential response to intervention components. This research illustrates the use of factorial designs to examine the interactions between person characteristics and relatively discrete intervention components. Future research is needed to replicate these findings.

Military experience helps setting reasonable personality characteristics but does not alter the criminal behavior-related impression of negative parental experience and alcoholism in a Chinese population

Personalities are determined by convergent factors, including physical environment, culture, special experience, and heredity. It has been shown that abuse of substance and alcohol among individuals with personality disorders predict criminality (Glenn and Raine, 2014; Hernandez-Avila et al., 2000). Thus, it is important to clarify the relationship between psychological characteristics and valence of criminal practice, even in the population without substance abuse. Here, we focused on a population with military experience in Shaanxi province of China to screen the psychological characteristics and correlate these characteristics to criminal behaviors. The study population included incarcerated veterans, incarcerated civilians, and three groups of military troops with different lengths of active duty history (<1 month, 1 year, and 2 years). We used the MAST (Michigan Alcoholism Screening Test), EMBU (Egna Minnen av Barndoms Uppfostran), and 16PF (Sixteen Personality Factor Questionnaire) for the screening purpose. Eight hundred seventy-five valid packets of questionnaires were collected during November 2014-January 2015. Comparison of the mean scores was used to evaluate the difference among the five groups. Incarcerated veterans and incarcerated civilians shared the alcohol abuse-relevant characteristics, including negative parental attitudes during their childhood and decreased emotional stability. Compared to the incarcerated civilians, incarcerated veterans scored higher in emotional stability, self-reliance, and perfectionism, but a lower score in apprehension. Personality characteristics associated with criminal behavior of incarcerated veterans seem to be unrelated to their military service per se as evidenced by the control groups. Conversely, military service may benefit the personnel characteristics even in the incarcerated veteran population.

Supplemental nicotine preloading for smoking cessation in posttraumatic stress disorder: Results from a randomized controlled trial

BACKGROUND

Individuals with posttraumatic stress disorder (PTSD) are more likely to smoke and more likely to relapse following a quit attempt than individuals without PTSD. Thus, there is a significant need to study promising interventions that might improve quit rates for smokers with PTSD. One such intervention, supplemental nicotine patch-preloading, entails the use of nicotine replacement therapy prior to quitting. Objective The objective of this study was to conduct a randomized controlled trial of the efficacy of supplemental nicotine patch-preloading among smokers with PTSD. We hypothesized that, relative to participants in the placebo condition, participants in the nicotine patch-preloading condition would: (1) smoke less and experience reduced craving for cigarettes during the nicotine patch-preloading phase; (2) experience less smoking-associated relief from PTSD symptoms and negative affect during the preloading phase; and (3) exhibit greater latency to lapse, and higher short- and long-term abstinence rates.

METHODS

Sixty-three smokers with PTSD were randomized to either nicotine or placebo patch for three weeks prior to their quit date. Ecological momentary assessment was used to assess craving, smoking, PTSD symptoms, and negative affect during the preloading period.

RESULTS

Nicotine patch-preloading failed to reduce smoking or craving during the preloading phase, nor was it associated with less smoking-associated relief from PTSD symptoms and negative affect. Moreover, no differences were observed between the treatment conditions for time to lapse, 6-week abstinence, or 6-month abstinence.

CONCLUSIONS

The findings from the present research suggest that supplemental nicotine patch-preloading is unlikely to substantially enhance quit rates among smokers with PTSD.

Integrating smoking cessation into mental health care for post-traumatic stress disorder

Background Post-traumatic stress disorder (PTSD) is associated with a high prevalence of smoking, heavy cigarette consumption and low cessation rates.

Purpose This manuscript describes the design of a randomized, multisite effectiveness trial to test whether integrating smoking cessation treatment into mental health care (integrated care) improves prolonged abstinence rates among veterans with PTSD, compared with referral to specialized smoking cessation clinics (usual standard of care). Secondary objectives are to assess the cost-effectiveness of integrated care relative to usual standard of care, identify treatment variables that mediate differences between conditions in outcome and determine whether smoking cessation is associated with worsening PTSD and/or depression.

Methods Following randomization, subjects (projected n = 1400) from 10 Veterans Health Administration (VHA) medical centers complete follow-up assessments every three or six months for up to four years. Endpoints include 1-year prolonged abstinence at 18 months postrandomization, 7- and 30-day point-prevalence abstinence and measures of depression, PTSD and economic outcomes.

Results This study is unique in providing the largest scale test of the feasibility and effectiveness of having mental health clinicians implement evidence-based smoking cessation treatment in psychiatric care settings for veterans with PTSD. It incorporates methodological features that are desirable for cessation treatment trials, including: a) assessment of clinically meaningful long-term smoking outcomes; b) a manual guiding delivery of the experimental intervention; c) independent ratings of clinician competence and treatment adherence and d) methods for training clinicians that would enhance implementation of tobacco cessation treatment in large health care systems.

Limitations Use of an exclusively VHA sample with few females limits generalizability. Conclusions The process for meeting challenges in designing this study may provide planning of other large-scale clinical effectiveness trials in tobacco control.

Findings have potential to initiate system-wide change in clinical practice patterns for tobacco cessation treatment involving patients with mental disorders. Clinical Trials 2007; 4: 178—189. http://ctj.sagepub.com

The Relationship between Interpersonal Violence Victimization and Smoking Behavior across Time and by Gender

The current study examined relationships between interpersonal violence victimization and smoking from childhood to adulthood. Data were from a community-based longitudinal study (N = 808) spanning ages 10 - 33. Cross-lag path analysis was used to model concurrent, directional, and reciprocal effects. Results indicate that childhood physical abuse predicted smoking and partner violence in young adulthood; partner violence and smoking were reciprocally related in the transition from young-adulthood to adulthood. Gender differences in this relationship were not detected. Social work prevention efforts focused on interpersonal violence and interventions targeting smoking cessation may be critical factors for reducing both issues.

Exploring Issues of Comorbid Conditions in People Who Smoke

Smoking affects comorbid disease outcomes, and patients with comorbid conditions may have unique characteristics that are important to consider when treating tobacco use. However, addressing tobacco in patients being treated for comorbid conditions is not a consistent practice. Recognizing the need for a "call-to-action" to address tobacco use in people with comorbid conditions, the Tobacco Treatment Network within the Society for Research on Nicotine and Tobacco (SRNT) convened a Comorbidities Workgroup to explore the relationship between smoking and comorbid disease to identify common themes including: the harms associated with continued tobacco use, the frequency of comorbid disease and tobacco use, the potential effect of comorbid disease on the ability to quit tobacco use, the association between tobacco use and suboptimal disease-specific treatment response, and evidence regarding potential approaches to improve addressing tobacco use in patients with comorbid disease. Five candidate conditions (psychiatric, cancer, cardiovascular, pulmonary, and human immunodeficiency virus infected patients) were explored. Across comorbid conditions, smoking adversely affects treatment efficacy and promotes other adverse health conditions. People with comorbid conditions who smoke are motivated to quit and respond to evidence-based smoking cessation treatments. However, tobacco cessation is not regularly incorporated into the clinical care of many individuals with comorbidities. Optimal strategies for addressing tobacco use within each comorbid disease are also not well defined. Further work is needed to disseminate evidence-based care into clinical practice for smokers with comorbid disease and addiction research should consider comorbid conditions as an important construct to explore.

IMPLICATIONS

This article explores how physical and psychiatric conditions may interact in the treatment of tobacco dependence, and discusses the need for smoking cessation as a critical component of comorbid condition management. Five common comorbid domains-psychiatric, cancer, pulmonary, cardiovascular, and human immunodeficiency virus (HIV)-are highlighted to illustrate how these different conditions might interact with smoking with respect to prevalence and harm, motivation to quit, and cessation treatment utilization and success.

Posttraumatic stress symptoms and smoking among World Trade Center disaster responders: A longitudinal investigation

PURPOSE

The current longitudinal study examined posttraumatic stress disorder (PTSD) symptom severity in relation to smoking abstinence and reduction over time among responders to the World Trade Center (WTC) disaster.

METHOD

Participants were 763 police and 1881 non-traditional (e.g., construction workers) WTC responders who reported being smokers at an initial examination obtained between July 2002 and July 2011 at the WTC Health Program (WTC-HP). WTC responders were reassessed, on average, 2.5 years later.

RESULTS

For police WTC responders, higher levels of WTC-related PTSD symptoms at the initial visit were associated with a decreased likelihood of smoking abstinence (OR=0.98, p=.002) and with decreased smoking reduction (β=-.06, p=.012) at the follow-up visit. WTC-related PTSD symptom severity was not related to likelihood of smoking abstinence or change in number of cigarettes smoked among non-traditional responders. Post hoc analyses suggested that for police, hyperarousal PTSD symptoms were predictive of decreased abstinence likelihood at the follow-up visit (OR=0.56, p=.006).

DISCUSSION

The present findings suggest that PTSD symptoms may be differentially related to smoking behavior among police and non-traditional WTC responders in a naturalistic, longitudinal investigation. Future work may benefit from exploring further which aspects of PTSD (as compared to each other and to common variance) explain smoking maintenance.

Smoking cessation and reduction in people with chronic mental illness

The high prevalence of cigarette smoking and tobacco related morbidity and mortality in people with chronic mental illness is well documented. This review summarizes results from studies of smoking cessation treatments in people with schizophrenia, depression, anxiety disorders, and post-traumatic stress disorder. It also summarizes experimental studies aimed at identifying biopsychosocial mechanisms that underlie the high smoking rates seen in people with these disorders. Research indicates that smokers with chronic mental illness can quit with standard cessation approaches with minimal effects on psychiatric symptoms. Although some studies have noted high relapse rates, longer maintenance on pharmacotherapy reduces rates of relapse without untoward effects on psychiatric symptoms. Similar biopsychosocial mechanisms are thought to be involved in the initiation and persistence of smoking in patients with different disorders. An appreciation of these common factors may aid the development of novel tobacco treatments for people with chronic mental illness. Novel nicotine and tobacco products such as electronic cigarettes and very low nicotine content cigarettes may also be used to improve smoking cessation rates in people with chronic mental illness.

Trauma exposure and cigarette smoking: the impact of negative affect and affect-regulatory smoking motives

Cognitive-affective mechanisms related to the maintenance of smoking among trauma-exposed individuals are largely unknown. Cross-sectional data from trauma-exposed treatment-seeking smokers (n = 283) were utilized to test a series of multiple mediator models of trauma exposure and smoking, as mediated by the sequential effects of negative affect and affect-modulation smoking motives. The sequential effects of both mediators indirectly predicted the effect of greater trauma exposure types on nicotine dependence, a biochemical index of smoking, perceived barriers to smoking cessation, and greater withdrawal-related problems during past quit attempts. Negative affect and affect-modulation motives for smoking may contribute to the trauma-smoking association.

Quitline Use and Outcomes among Callers with and without Mental Health Conditions: A 7-Month Follow-Up Evaluation in Three States

Objectives. To examine abstinence outcomes among tobacco users with and without a reported mental health condition (MHC) who enrolled in state tobacco quitline programs. Methods. Data were analyzed from a 7-month follow-up survey (response rate: 41% [3,132/7,459]) of three state-funded telephone quitline programs in the United States that assessed seven self-reported MHCs at quitline registration. We examined 30-day point prevalence tobacco quit rates for callers with any MHC versus none. Data were weighted to adjust for response bias and oversampling. Multivariable logistic regression was used to examine cessation outcomes. Results. Overall, 45.8% of respondents reported ≥1 MHC; 57.4% of those reporting a MHC reported ≥2 MHCs. The unadjusted quit rate for callers with any MHC was lower than for callers with no MHC (22.0% versus 31.0%, P < 0.001). After adjusting for demographics, nicotine dependence, and program engagement, callers reporting ≥1 MHC were less likely to be abstinent at follow-up (adjusted OR = 0.63, 95% CI = 0.51–0.78, P < 0.001). Conclusions. More intensive or tailored quitline programs may need to be developed among callers with MHCs as their quit rates appear to be lower than callers without MHCs.

Effectiveness of the tobacco tactics program for psychiatric inpatient veterans: an implementation study

BACKGROUND

The objective of this study was to evaluate the effectiveness of the inpatient, nurse-administered Tobacco Tactics program for patients admitted for psychiatric conditions in two Veterans Affairs (VA) hospitals compared to a control hospital.

METHODS

This is a subgroup analysis of data from the inpatient tobacco tactics effectiveness trial, which was a longitudinal, pre- post-nonrandomized comparison design with 6-month follow-up in the three large Veterans Integrated Service Networks (VISN) 11 hospitals.

RESULTS

Six-month self-reported quit rates for patients admitted for psychiatric conditions increased from 3.5% pre-intervention to 10.2% post-intervention compared to a decrease in self-reported quit rates in the control hospital (12% pre-intervention to 1.6% post-intervention). There was significant improvement in self-reported quit rates for the pre- versus post-intervention time periods in the Detroit and Ann Arbor intervention sites compared to the Indianapolis control site (P=0.01) and cotinine results were in the same direction.

CONCLUSION

The implementation of the Tobacco Tactics intervention has the potential to significantly decrease smoking and smoking-related morbidity and mortality among smokers admitted to VA hospitals for psychiatric disorders.

Acceptance and commitment therapy smoking cessation treatment for veterans with posttraumatic stress disorder: a pilot study

OBJECTIVE

Veterans with PTSD smoke at rates two to three times higher than the general population, while their quit rate is less than half that of the general population. The present study evaluated the feasibility, acceptability, and preliminary efficacy of Acceptance and Commitment Therapy for Veterans With Posttraumatic Stress Disorder (PTSD) and Tobacco Addiction (ACT-PT), which focuses on helping veterans overcome emotional challenges to quitting smoking.

METHODS

Veterans with current PTSD who smoked 15 or more cigarettes/day (N = 19) participated in an open trial of ACT-PT. Participants attended nine weekly individual counseling sessions and received eight weeks of nicotine patch therapy. Primary outcomes included feasibility and acceptability of the intervention, and secondary outcomes included expired-air carbon monoxide confirmed seven-day point prevalence abstinence, cravings, and PTSD symptoms.

RESULTS

The retention rate for ACT-PT was good (74%) and client satisfaction ratings were high. Participants made multiple quit attempts (M = 3.6, SD = 4.2) during the study period and were significantly more confident that they could quit smoking at three-month follow-up. At the end of treatment, 37% of participants were abstinent from smoking and 16% were abstinent at three-month follow-up. Overall, participants reduced their smoking by 62% at the end of treatment and 43% at three-month follow-up. PTSD symptoms and smoking urges significantly decreased from baseline to the end of treatment and three-month follow-up.

CONCLUSIONS

ACT-PT appears to be a promising smoking cessation treatment for veterans with PTSD. Future research should evaluate ACT-PT in a randomized controlled trial.

Anxiety, depression, and cigarette smoking: a transdiagnostic vulnerability framework to understanding emotion-smoking comorbidity

Research into the comorbidity between emotional psychopathology and cigarette smoking has often focused upon anxiety and depression's manifest symptoms and syndromes, with limited theoretical and clinical advancement. This article presents a novel framework to understanding emotion-smoking comorbidity. We propose that transdiagnostic emotional vulnerabilities-core biobehavioral traits reflecting maladaptive responses to emotional states that underpin multiple types of emotional psychopathology-link various anxiety and depressive psychopathologies to smoking. This framework is applied in a review and synthesis of the empirical literature on 3 transdiagnostic emotional vulnerabilities implicated in smoking: (a) anhedonia (Anh; diminished pleasure/interest in response to rewards), (b) anxiety sensitivity (AS; fear of anxiety-related sensations), and (c) distress tolerance (DT; ability to withstand distressing states). We conclude that Anh, AS, and DT collectively (a) underpin multiple emotional psychopathologies, (b) amplify smoking's anticipated and actual affect-enhancing properties and other mechanisms underlying smoking, (c) promote progression across the smoking trajectory (i.e., initiation, escalation/progression, maintenance, cessation/relapse), and (d) are promising targets for smoking intervention. After existing gaps are identified, an integrative model of transdiagnostic processes linking emotional psychopathology to smoking is proposed. The model's key premise is that Anh amplifies smoking's anticipated and actual pleasure-enhancing effects, AS amplifies smoking's anxiolytic effects, and poor DT amplifies smoking's distress terminating effects. Collectively, these processes augment the reinforcing properties of smoking for individuals with emotional psychopathology to heighten risk of smoking initiation, progression, maintenance, cessation avoidance, and relapse. We conclude by drawing clinical and scientific implications from this framework that may generalize to other comorbidities.

[Psychodynamic psychotherapy, lifestyle and prevention]

OBJECTIVES

Patients with mental disorders frequently manifest unhealthy behavior, which contributes to their increased risk for chronic mental and somatic diseases as well as excess mortality rates of 10 years and more. It also impairs their well-being and the course of mental disorders.We analyzed whether by addressing unhealthy behavior prevention can be integrated into psychodynamic psychotherapy.

METHODS

We reviewed the literature on the role of unhealthy behavior for mental disorders, on the role of lifestyle risk factors in psychodynamic theory, and on barriers to the integration of addressing lifestyle in psychodynamic psychotherapy.

RESULTS

Smoking, unhealthy dietary habits, and physical inactivity constitute dysfunctional behavior, resulting from maladaptive self-representations and an impairment of emotion-regulation capacities. In psychodynamic psychotherapy this maladaptive behavior can be addressed and treated as a kind of defensive behavior and resistance.

CONCLUSION

We believe that by addressing unhealthy behavior prevention can become a crucial task for psychodynamic psychotherapists today.

Outcomes following treatment of veterans for substance and tobacco addiction

Persons who use tobacco in addition to alcohol and other drugs have increased health risks and mortality rates. The purpose of this study was to evaluate the impact of participation in a tobacco cessation program on tobacco, alcohol, and other drug use in a population seeking treatment for substance use disorders (SUDs). Tobacco, alcohol, and other drug use were assessed by urine drug screens, breathalyzer readings, and self-report. Veterans (N=137) with a tobacco use disorder enrolled in inpatient program for the treatment of SUDs at the Salem Veterans Affairs Medical Center participated in tobacco cessation education as part of their treatment programming. Use of tobacco, drugs and/or alcohol was evaluated upon admission, 2 weeks following admission, at discharge and 1 month following graduation. The 1-month follow-up rate was 70.8%, with 97 veterans completing the follow-up assessment. Of those 97 veterans, 90.7% (n=88) reported abstinence from alcohol and 91.8% (n=89) reported abstinence from other drugs of abuse. Fourteen veterans (14.4%) reported abstinence from tobacco at the 1-month follow-up. The veterans reporting abstinence from tobacco use also reported abstinence from alcohol and other drugs at the 1-month follow-up.

Smokers with serious mental illness and requests for nicotine replacement therapy post-hospitalisation

BACKGROUND AND AIMS

Smoke-free psychiatric hospitalisation provides opportunity for initiating tobacco cessation treatment. The current study reports on psychiatric patients' interest in continuing nicotine replacement therapy (NRT) posthospitalisation and examines patient predictors of NRT requests, quit attempts and abstinence at 1-week follow-up.

METHODS

Daily smokers were recruited and interviewed on locked psychiatric units at three smoke-free San Francisco Bay Area hospitals. Intent to quit smoking was not required to participate and 73% of eligible smokers enrolled. Analyses focused on 816 participants (49% female) randomised to interventions providing counselling tailored to readiness to quit with availability of NRT posthospitalisation. Logistic regressions tested demographic, smoking and psychiatric factors predictive of NRT requests, quit attempts and abstinence 1-week postdischarge.

RESULTS

Participants averaged 17 (SD=10) cigarettes/day for an average of 19 (SD=14) years. Most (88%) requested study-provided NRT (74% right at discharge). Participants preparing to quit and those with more severe psychiatric symptoms were more likely to request NRT at discharge (p<0.01). Those with more severe psychiatric symptoms also were more likely to request NRT refill, as were older participants (p<0.05). Participants who requested NRT at discharge were more likely to make a 24 h quit attempt and self-report abstinence at the 1-week follow-up (54% quit attempt, 14% abstinent) than participants who did not (25% quit attempt, 4% abstinent) (p<0.05).

CONCLUSIONS

The great demand for NRT and the association between NRT use with quit attempts and abstinence at 1-week posthospitalisation supports adoption of tobacco treatment in acute psychiatric settings.

Anxiety sensitivity mediates relations between emotional disorders and smoking

Research has documented consistent and robust relations between emotional disorders (i.e., depressive and anxiety disorders) and smoking. Yet, it is presently unclear whether anxiety sensitivity--the fear of aversive internal anxiety states--accounts for the relations between emotional disorders and various smoking processes, including nicotine dependence, perceived barriers to smoking cessation, and severity of problematic symptoms during past cessation attempts. Participants (N = 465) were treatment-seeking daily tobacco smokers recruited as part of a larger tobacco-cessation study. Baseline (pretreatment) data were utilized. Emotional disorders were assessed via clinical diagnostic interview; self-report measures were used to assess anxiety sensitivity and 3 criterion variables: nicotine dependence, barriers to smoking cessation, and severity of problematic symptoms while quitting in past attempts. Emotional disorders were predictive of higher levels of nicotine dependence, greater perceived barriers to cessation, and greater severity of problematic symptoms while attempting to quit in the past; each of these relations were accounted for by the indirect effect of anxiety sensitivity. The present findings suggest that anxiety sensitivity may be an important transdiagnostic construct in explicating the nature of the relations between emotional disorders and various smoking processes.

PTSD symptomatology and readiness to quit smoking among women with serious mental illness

INTRODUCTION

Posttraumatic stress disorder (PTSD) is a risk factor for tobacco addiction. The majority of research on PTSD and smoking has been conducted with men, particularly combat veterans, and little is known about the association among women. In a clinical sample of women civilian smokers with serious mental illness (SMI), we examined the prevalence of PTSD symptomatology and associations with physical and mental health functioning, co-occurring substance use, nicotine dependence, and readiness to quit smoking.

METHODS

376 adult women smokers aged 18-73 were recruited from 7 acute inpatient psychiatry units and screened by diagnostic interview for current PTSD symptomatology (PTSD(+)). In multiple regressions, we examined the associations of screening PTSD(+) with physical and mental health functioning; past-month drug use; past-year substance use disorders; nicotine dependence and readiness to quit smoking.

RESULTS

Nearly half the sample (43%) screened PTSD(+), which was significantly associated with the use of stimulants (OR=1.26) and opiates (OR=1.98), drug use disorders (OR=2.01), and poorer mental health (B=-2.78) but not physical health functioning. PTSD(+) status was unrelated to nicotine dependence, but predicted greater desire to quit smoking (B=2.13) and intention to stop smoking in the next month (OR=2.21). In multivariate models that adjusted for substance use disorders, physical and mental health functioning, and nicotine dependence, screening PTSD(+) remained predictive of greater desire and intention to quit smoking.

CONCLUSION

PTSD symptomatology was common in our sample of women smokers with SMI and associated with not only worse substance use and mental health, but also greater readiness to quit smoking, suggesting the need for and potential interest in integrative PTSD-addiction treatment among women.

Comparison of an Intensive Pharmacist-Managed Telephone Clinic With Standard of Care for Tobacco Cessation in a Veteran Population

Purpose. To evaluate the effectiveness of the Pharmacist-Managed Telephone Tobacco Cessation Clinic (PMTTCC) compared to the standard of care (SOC) at the Veterans Affairs San Diego Healthcare System. Method. A retrospective cohort study was performed investigating the proportion of veterans who quit smoking at 6 months while enrolled in the PMTTCC. Chart review was performed using the Veterans Affairs Computerized Patient Record System. The PMTTCC group included patients who had received medication and counseling from the tobacco cessation pharmacists. The cohort was compared to a matched SOC group who did not receive counseling, only tobacco cessation medication therapy through a primary care provider. The primary outcome for this study was patient-reported tobacco cessation at 6 months. Secondary outcomes were abstinence at 1 and 3 months. Results. A total of 1,006 patients were included in the analysis, 503 patients from the PMTTCC and 503 patients from SOC. The overall study population was 54 years old on average, 92.5% male, 70.0% Caucasian, 45.5% with history of psychiatric conditions, and had an average smoking history of 33-pack years. Patients in the PMTTCC group had statistically significant improvements in abstinence at 6 months versus the SOC group (81/503, 16.1% vs. 48/503, 9.5%; p < .0001). Quitters were older on average versus non-quitters (56.03 vs. 53.65 years; p = .01). Conclusion. Patients enrolled in the PMTTCC had improved tobacco abstinence rates at 6 months compared to SOC. Although the study was not designed to test for causality, the results lend support for using intensive tobacco cessation management in veteran population.

The relationship between nicotine cessation and mental disorders in a nationally representative sample

The objective of this study was to examine the relationship between Axis I and II mental disorders, quality of life, and nicotine dependence cessation in a nationally representative sample. Data came from Wave 2 of the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC), a nationally representative survey of adults in the United States (N = 34,653). People who met DSM-IV criteria for nicotine dependence previously but who had abstained from nicotine in the last year (nicotine cessation) were compared to people currently dependent on nicotine as well as lifetime abstainers using multivariate logistic regression. Outcomes of interest included DSM-IV Axis I and II mental disorders, treatment seeking for mental disorders, and quality of life measures. In adjusted models, individuals who ceased nicotine use in the last year were less likely to have past-year mood [adjusted odds ratio (AOR) = 0.64; 95% confidence interval (CI) 0.50-0.82, p < 0.001] and substance use disorders (AOR = 0.65, 95% CI 0.52-0.82, p < 0.001) compared to those with current nicotine dependence. They were also less likely to have narcissistic and borderline personality disorders. Compared to those with current nicotine dependence, cessation was associated with an improved quality of life, both physically (beta = 1.65; standard error 0.40, p < 0.001) and mentally (beta = 2.17, standard error 0.39, p < 0.001). In conclusion, nicotine dependence cessation was associated with reduced likelihood of several mental disorders and a higher quality of life compared to those with current nicotine dependence. These findings provide further support for public health policy aimed at smoking cessation.

Evaluating interventions to improve somatic health in severe mental illness: a systematic review

OBJECTIVE

To present a systematic review of the evaluation of randomized interventions directed toward improving somatic health for patients with severe mental illness (SMI).

METHOD

A systematic search in PubMed, Embase, Cinahl, and PsycInfo was performed. The scope of the search was prospective studies for patients aged 18-70, published from January 2000 till June 2011. Randomized interventions directed toward improving somatic health for patients with SMI were selected. We excluded studies on elderly, children, and studies performed before 2000. Information on population, type of intervention, follow-up, outcome measures, and on authors' conclusions were drawn from the original articles.

RESULTS

Twenty-two original studies were included, presenting four types of interventions: health education (n = 9), exercise (n = 6), smoking cessation (n = 5), and changes in health care organization (n = 2). To evaluate the effect of these studies 93 different outcome measures were used in 16 categories.

CONCLUSION

Many interventions directed toward improving somatic health for patients with SMI have been started. These studies did not apply similar evaluations, and did not use uniform outcome measures of the effect of their interventions. Valuable comparisons on effectiveness are therefore almost impossible.

Initial evaluation of an integrated treatment for comorbid PTSD and smoking using a nonconcurrent, multiple-baseline design

The present study examined an integrated treatment for comorbid posttraumatic stress disorder (PTSD) and smoking entitled "Smoke-Free to Overcome PTSD: An Integrated Treatment" (STOP IT program). A nonconcurrent multiple-baseline design was used with six community-recruited adult smokers with PTSD to investigate both patient acceptance of the treatment and its initial efficacy on both PTSD and smoking. Potential order effects of exposure-based and affect management components were also examined. A gold-standard assessment strategy that included the Clinician Administered PTSD Scale (Blake et al., 1995) and biochemical verification of self-reported smoking status was employed to measure primary targets of treatment. Results suggested that the STOP IT program was well tolerated. There were clinically significant improvements in PTSD outcomes, but only temporary reductions in smoking. Participants' relatively low posttreatment smoking levels increased by the follow-up assessment, although not to baseline levels. Treatment component order did not appear to affect treatment outcomes, but those who were assigned to the exposure-focused writing prior to affect management training condition appeared more likely to discontinue treatment before beginning exposure. These preliminary data support the safety, acceptability, and potential efficacy of the STOP IT program. Future investigation of the STOP IT program should include testing the incremental efficacy of increasing the dose of smoking-focused intervention, as well as randomized controlled tests of the treatment that employ gold standards for treatment outcome research.

Combat posttraumatic stress disorder, substance use disorders, and traumatic brain injury

Among both civilian and veteran populations, substance use disorders (SUDs) and anxiety disorders frequently co-occur. One of the most common comorbid anxiety disorder is posttraumatic stress disorder (PTSD), a condition which may develop after exposure to traumatic events, such as military combat. In comparison with the general population, rates of both SUDs and PTSD are elevated among veterans. Recent data show that soldiers returning from Iraq and Afghanistan demonstrate high rates of co-occurring SUDs, PTSD, and traumatic brain injury. Careful assessment of these conditions is critical and may be complicated by symptom overlap. More research targeting integrated interventions for these conditions is needed to establish optimal treatments.

Treatment of tobacco dependence in people with mental health and addictive disorders

People with mental health and addictive disorders (MHADs) have higher rates of cigarette smoking, and less success in quitting smoking compared with the general population. Moreover, tobacco-related medical illness may be the leading cause of death in the MHAD population. We discuss the scope of this comorbidity, and approaches to the treatment of tobacco dependence in people with MHAD, including schizophrenia, mood disorders, anxiety disorders, and alcohol and substance use disorders. Finally, at the level of health systems, we emphasize the importance of integrated treatment of tobacco dependence in MHADs.

Intensive intervention for alcohol-dependent smokers in early recovery: a randomized trial

INTRODUCTION

The purpose of this study was to investigate the efficacy of an intensive tobacco cessation intervention for alcohol-dependent smokers in early recovery.

METHODS

A total of 162 alcohol-dependent smokers were randomized to either intensive intervention for smoking cessation or usual care. The intensive intervention consisted of 16 sessions of individual cognitive behavior therapy (CBT) and combination nicotine replacement therapy that lasted 26 weeks. Usual care involved referral to a free-standing smoking cessation program that provided smoking cessation counseling of varying duration and guideline-concordant medications. The primary cessation outcome was verified 7-day point prevalence abstinence (PPA) at 12, 26, 38, and 52 weeks.

RESULTS

At 12 and 26 weeks, the verified 7-day point-prevalence quit rate was significantly higher for the intensive intervention group than for the usual care group (both p=0.03). However, the quit rates for the two treatment groups were not significantly different at 38 or 52 weeks. Verified 30-day alcohol abstinence rates were not significantly different for the two treatment groups at any of the follow-up assessments.

CONCLUSIONS

The intensive smoking cessation intervention yielded a higher short-term smoking quit rate without jeopardizing sobriety. A chronic care model might facilitate maintenance of smoking cessation during the first year of alcohol treatment and perhaps for longer periods of time. It is hoped that studies such as this will inform the development of more effective interventions for concurrent alcohol and tobacco use disorders.

Smoking reduction for persons with mental illnesses: 6-month results from community-based interventions

Persons with mental illnesses use tobacco at significantly higher and heavier rates than the general population, and suffer greater tobacco- related morbidity and mortality. However, there are few existing tobacco cessation interventions for these individuals. This study examined two tobacco cessation interventions, a telephonic quitline intervention (counseling and nicotine replacement therapy) and a community-based group counseling intervention with adults currently receiving community mental health services. At 6-month follow-up, both groups demonstrated significantly reduced tobacco use, but participants who received both quitline services and the group counseling intervention were significantly more likely to have a 50% tobacco use reduction. Across groups, the overall intent-to-treat cessation rate was 7%. Tobacco dependence, depression symptoms, and psychotic symptoms decreased significantly for all treatment groups, while health and mental health functioning increased. Findings suggest that common community tobacco cessation services are effective for this population.

A systematic review and meta-analysis of the effectiveness of behavioural smoking cessation interventions in selected disadvantaged groups

AIMS

A systematic review and meta-analysis was conducted to assess the methodological quality and effectiveness of behavioural smoking cessation interventions targeted at six disadvantaged groups; the homeless, prisoners, indigenous populations, at-risk youth, individuals with low socio-economic status and individuals with a mental illness.

METHODS

Medline, EMBASE, the Cochrane Library and PsycInfo databases were searched using MeSH and keywords for studies conducted in developed countries prior to October 2010. Included studies were assessed for methodological quality. A DerSimonian and Laird random effects meta-analysis was conducted where possible to explore the effectiveness of interventions for the different subgroups. A narrative review was conducted for studies unable to be included in the meta-analysis. Outcomes examined were abstinence rates at short-term (up to 3 months) and long-term (6 months or the longest) follow-up.

RESULTS

Thirty-two relevant studies were identified. The majority (n = 20) were rated low in methodological quality. Results of the meta-analysis showed a significant increase in cessation for behavioural support interventions targeted at low-income female smokers at short-term follow-up [relative risk (RR) 1.68, confidence interval (CI) 1.21-2.33], and behavioural support interventions targeted at individuals with a mental illness at long-term follow-up (RR 1.35, CI 1.01-1.81). Results of the narrative review showed several promising interventions that increased cessation rates at 6-month or longer follow-up.

CONCLUSIONS

Few well-controlled trials have examined the most effective smoking cessation strategies for highly disadvantaged groups, especially among the homeless, indigenous smokers and prisoners. The use of behavioural smoking cessation interventions for some socially disadvantaged groups appears promising; however, overall findings are inconsistent. Further research is needed to establish the most effective interventions for vulnerable high-risk groups. Special attention should be given to increasing sample size and power, and to sound evaluation methodology to overcome methodological limitations of conducting research with these high-risk groups.

An online survey of tobacco use, intentions to quit, and cessation strategies among people living with bipolar disorder

OBJECTIVES

  Tobacco use is prevalent among people living with bipolar disorder. We examined tobacco use, attempts to quit, and tobacco-related attitudes and intentions among 685 individuals with bipolar disorder who smoked ≥ 100 cigarettes in their lifetime.

METHODS

  Data were collected online through the website of the Depression and Bipolar Support Alliance, a mood disorder peer-support network.

RESULTS

  The sample was 67% female, 67% aged 26 to 50, and 89% Caucasian; 87% were current smokers; 92% of current smokers smoked daily, averaging 19 cigarettes/day (SD=11). The sample began smoking at a mean age of 17 years (SD=6) and smoked a median of 7 years prior to bipolar disorder diagnosis. Among current smokers, 74% expressed a desire to quit; intent to quit smoking was unrelated to current mental health symptoms [χ(2) (3)=5.50, p=0.139]. Only 33% were advised to quit smoking by a mental health provider, 48% reported smoking to treat their mental illness, and 96% believed being mentally healthy was important for quitting. Ex-smokers (13% of sample) had not smoked for a median of 2.7 years; 48% quit 'cold turkey.' Most ex-smokers (64%) were in poor or fair mental health when they quit smoking. At the time of the survey, however, more ex-smokers described their mental health as in recovery than current smokers [57% versus 40%; χ(2) (3)=11.12, p=0.011].

CONCLUSIONS

  Most smokers living with bipolar disorder are interested in quitting. The Internet may be a useful cessation tool for recruiting and potentially treating smokers with bipolar disorder who face special challenges when trying to quit and rarely receive cessation treatment from their mental health providers.

Integrating tobacco cessation into mental health care for posttraumatic stress disorder: a randomized controlled trial

CONTEXT

Most smokers with mental illness do not receive tobacco cessation treatment.

OBJECTIVE

To determine whether integrating smoking cessation treatment into mental health care for veterans with posttraumatic stress disorder (PTSD) improves long-term smoking abstinence rates.

DESIGN, SETTING, AND PATIENTS

A randomized controlled trial of 943 smokers with military-related PTSD who were recruited from outpatient PTSD clinics at 10 Veterans Affairs medical centers and followed up for 18 to 48 months between November 2004 and July 2009.

INTERVENTION

Smoking cessation treatment integrated within mental health care for PTSD delivered by mental health clinicians (integrated care [IC]) vs referral to Veterans Affairs smoking cessation clinics (SCC). Patients received smoking cessation treatment within 3 months of study enrollment.

MAIN OUTCOME MEASURES

Smoking outcomes included 12-month bioverified prolonged abstinence (primary outcome) and 7- and 30-day point prevalence abstinence assessed at 3-month intervals. Amount of smoking cessation medications and counseling sessions delivered were tested as mediators of outcome. Posttraumatic stress disorder and depression were repeatedly assessed using the PTSD Checklist and Patient Health Questionnaire 9, respectively, to determine if IC participation or quitting smoking worsened psychiatric status.

RESULTS

Integrated care was better than SCC on prolonged abstinence (8.9% vs 4.5%; adjusted odds ratio, 2.26; 95% confidence interval [CI], 1.30-3.91; P = .004). Differences between IC vs SCC were largest at 6 months for 7-day point prevalence abstinence (78/472 [16.5%] vs 34/471 [7.2%], P < .001) and remained significant at 18 months (86/472 [18.2%] vs 51/471 [10.8%], P < .001). Number of counseling sessions received and days of cessation medication used explained 39.1% of the treatment effect. Between baseline and 18 months, psychiatric status did not differ between treatment conditions. Posttraumatic stress disorder symptoms for quitters and nonquitters improved. Nonquitters worsened slightly on the Patient Health Questionnaire 9 relative to quitters (differences ranged between 0.4 and 2.1, P = .03), whose scores did not change over time.

CONCLUSION

Among smokers with military-related PTSD, integrating smoking cessation treatment into mental health care compared with referral to specialized cessation treatment resulted in greater prolonged abstinence.

TRIAL REGISTRATION

clinicaltrials.gov Identifier: NCT00118534.

Smoking outcome by psychiatric history after behavioral and varenicline treatment

Treatment outcomes were compared across smokers enrolled in the COMPASS cessation trial with (positive psychiatric history [PH+], n = 271) and without (PH-, n = 271) a diagnosis of PH based on medical record evidence of anxiety, depression, psychotic disorder, or bipolar disorder. Everyone received behavioral counseling plus varenicline and was followed for 6 months post quit date. PH+ smokers took varenicline for fewer days on average (59.4 vs. 68.5, p < or = .01) but did not differ in their use of behavioral treatment. PH+ smokers were more likely to report anxiety and depression, but side-effect intensity ratings did not differ after adjusting for multiple comparisons. Overall, all side effects were rated as moderate intensity or less. Groups had similar 30-day abstinence rates at 6 months (31.5% PH+ vs. 35.4% PH-, p = .35). In sum, having a psychiatric diagnosis in this trial did not predict worse treatment outcome or worse treatment side effects.
