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

Tobacco use, trauma exposure and PTSD: a systematic review

Tobacco use remains one of the most significant preventable public health problems globally and is increasingly concentrated among vulnerable groups, including those with trauma exposure or diagnosed with PTSD. The goal of this systematic review was to update and extend previous reviews. Of the 7224 publications that met the initial criteria, 267 were included in the review. Summary topic areas include conceptual frameworks for the relation between trauma or PTSD and tobacco use; associations between trauma exposure or PTSD and tobacco use; number and type of trauma exposures and tobacco use; PTSD symptoms and tobacco use; Treatment-related studies; and the examination of causal relations. Evidence continues to indicate that individuals exposed to trauma or diagnosed with PTSD are more likely to use tobacco products, more nicotine dependent and less likely to abstain from tobacco even when provided evidence-based treatments than individuals without trauma. The most commonly cited causal association proposed was use of tobacco for self-regulation of negative affect associated with trauma. A small proportion of the studies addressed causality and mechanisms of action. Future work should incorporate methodological approaches and measures from which we can draw causal conclusions and mechanisms to support the development of viable therapeutic targets.

Tobacco Treatment Knowledge and Practices Among US Psychiatrists

This study explores the extent to which psychiatrists are familiar with, and utilize, the USPHS guidelines for treating tobacco use and dependence (i.e., the 5A's), deliver cessation treatment, and the barriers they perceive to doing so. An original, national survey of 141 psychiatrists revealed that most Ask patients if they smoke (81.6%). Fewer Advise them to stop (78.7%) and Assess their willingness to quit (73.6%). A minority Assist with a quit plan (15.9%) and Arrange for follow-up (26.4%). Just 11.9% have used the USPHS guidelines in clinical practice; 37% have never heard of them. Even among those who say they have used the USPHS guidelines, implementation of the 5A's is quite low. Time-related factors were the most common barriers to cessation delivery (51.4%). Patient factors (30%) and financial/resource factors (25%) were less common. There is a strong need for increased implementation of clinical guidelines for evidence-based tobacco treatments among psychiatrists.

Trauma Symptoms and Social Support Mediate the Impact of Violence Exposure on Parenting Competence Among Substance-Dependent Mothers

Women with substance use disorders (SUDs) experience high rates of violence exposure and posttraumatic stress disorder (PTSD), which are associated with parenting anxiety and lower parenting satisfaction among mothers. Although social support may buffer the impact of violence and PTSD on parenting, violence exposure and PTSD may impair mothers' ability to create, perceive, and utilize social support. We examined the impact of violence exposure, trauma symptoms, and interpersonal support on parenting competence among 291 mothers with substance dependence, using ordinary least squares regression and path analysis. Greater violence exposure and trauma symptoms were associated with lower parenting competence. Greater interpersonal support was associated with greater parenting competence. Trauma symptoms and interpersonal support sequentially mediated the impact of violence exposure on parenting competence, suggesting one pathway through which violence exposure may affect parenting among substance-dependent mothers. Implications for practice include the need to utilize trauma-informed interventions that modify social support.

Potential Moderating Effects of Psychiatric Diagnosis and Symptom Severity on Subjective and Behavioral Responses to Reduced Nicotine Content Cigarettes

INTRODUCTION

Given FDA's authority to implement a cigarette nicotine reduction policy, possible outcomes of this regulation must be examined, especially among those who may be most affected, such as those with comorbid psychiatric disorders.

METHODS

In this secondary analysis of a multisite, randomized, clinical laboratory study, we used analyses of variance to examine the effects of nicotine dose (0.4, 2.4, 5.2, and 15.8 mg/g of tobacco), depressive and anxiety diagnoses (depression only, anxiety only, both, or neither), and depressive and anxiety symptom severity on cigarette choice, smoke exposure, craving, and withdrawal across three vulnerable populations: socioeconomically disadvantaged women of reproductive age, opioid-dependent individuals, and those with affective disorders (n = 169).

RESULTS

Diagnosis and symptom severity largely had no effects on smoking choice, total puff volume, or CO boost. Significant main effects on craving and withdrawal were observed, with higher scores in those with both anxiety and depression diagnoses compared with depression alone or no diagnosis, and in those with more severe depressive symptoms (p's < .001). These factors did not interact with nicotine dose. Cigarettes with <15.8 mg/g nicotine were less reinforcing, decreased total puff volume, and produced significant but lower magnitude and shorter duration reductions in craving and withdrawal than higher doses (p's < .01).

CONCLUSIONS

Reducing nicotine dose reduced measures of cigarette addiction potential, with little evidence of moderation by either psychiatric diagnosis or symptom severity, providing evidence that those with comorbid psychiatric disorders would respond to a nicotine reduction policy similarly to other smokers.

IMPLICATIONS

Thus far, controlled studies in healthy populations of smokers have demonstrated that use of very low nicotine content cigarettes reduces cigarette use and dependence without resulting in compensatory smoking. These analyses extend those findings to a vulnerable population of interest, those with comorbid psychiatric disorders. Cigarettes with very low nicotine content were less reinforcing, decreased total puff volume, and produced significant but lower magnitude and shorter duration reductions in craving and withdrawal than higher doses. These nicotine dose effects did not interact with psychiatric diagnosis or mood symptom severity suggesting that smokers in this vulnerable population would respond to a nicotine reduction strategy similarly to other smokers.

Maternal and Paternal Warmth Impact Recovery Support and Social Network Composition for Substance Dependent African American and Non-African American Women

Poor early relationship experiences during the first 16 years of life may negatively impact adults' capacity to establish and utilize social support (Suchman, McMahon, Slade, & Luthar, 2005). This is especially of concern for women with substance use disorders (SUD) for whom social support is associated with recovery maintenance and treatment retention (Gregoire & Snively, 2001). The purpose of this study was to examine the influence of early relationship experiences, specifically paternal and maternal warmth, on recovery related social support and personal network characteristics among African American (AA) and non-AA women in treatment for SUD. Data were collected from 254 women in substance abuse treatment, 146 AA and 108 non-AA. Ordinal logistic, Poisson or multiple linear regressions were fitted to predict the impact of maternal and paternal warmth during childhood on adult social network composition and recovery support. Greater maternal warmth was associated with greater recovery-specific social support for both AA (β = 0.12) and non-AA (β = 0.15) women. Paternal, but not maternal, warmth significantly predicted the number of social network members who supported recovery for non-AA women (AOR = 1.04), and number of network members who used drugs and alcohol for AA women (IRR = 0.99). Developmental experiences associated with fathers appear to affect different domains of adult functioning than those associated with mothers, and those effects are different for AA versus non-AA women. Attention to these differences may inform culturally relevant substance abuse prevention and treatment efforts.

Posttraumatic stress disorder and tobacco use: A systematic review and meta-analysis

Posttraumatic stress disorder (PTSD) and tobacco use are prevalent conditions that co-occur at striking rates in the US. Previous reviews examined prevalence and factors associated with cigarette smoking among individuals with PTSD but have not been summarized since 2007. Moreover, none explored rates and factors associated with the use of other tobacco products. This study aimed to systematically review the most recent literature examining the comorbidity of PTSD and tobacco use to provide prevalence rates, as well as summarize the literature exploring other factors associated with tobacco use among individuals with PTSD. Studies were identified using a systematic search of keywords related to tobacco use and PTSD within the following databases: PubMed, PsycINFO, Web of Knowledge, CINAHL, PsycARTICLES, and Cochrane Clinical Trials Library. The studies included in this review (N = 66) showed that the prevalence of current use of tobacco products in individuals with PTSD was 24.0% and the rate of PTSD among users of tobacco products was 20.2%. Additionally, results demonstrated that individuals with PTSD present with high levels of nicotine dependence and heavy use of tobacco products, as well as underscore the importance of negative emotional states as a contributing factor to tobacco use among individuals with PTSD. It is imperative that future studies continue monitoring tobacco use among individuals with PTSD while also assessing factors identified as having a prominent role in tobacco use among individuals with PTSD. These findings also demonstrate the need for more innovative approaches to reduce the pervasive tobacco use among individuals with PTSD.

Predicted Impact of Nicotine Reduction on Smokers with Affective Disorders

OBJECTIVES

In 2009 the FDA acquired the authority to reduce the nicotine content in cigarettes if appropriate for public health, prompting research to evaluate the implications of this policy scientifically. Studies in non-psychiatric populations show that reducing the nicotine content of cigarettes to non-addictive levels reduces smoking rates and nicotine dependence. However, few studies have examined this hypothesis in vulnerable populations.

METHODS

In this narrative review we examined the extant literature on the effects of nicotine reduction or cessation on symptoms of withdrawal, as well as psychiatric symptoms, among those with affective disorders.

RESULTS

Following initial withdrawal from nicotine, smokers with affective disorders experience more severe mood disruption than smokers without these disorders. Use of very low nicotine content (VLNC) cigarettes during abstinence may help mitigate the mood-disrupting effects of initial abstinence. Once the initial effects of nicotine withdrawal on mood have passed, longer-term abstinence is associated with psychiatric improvement rather than worsening.

CONCLUSIONS

These findings suggest that if a national nicotine reduction policy were to be implemented, smokers with affective disorders would need additional support to overcome initial withdrawal but that long-term outcomes would likely be positive.
