Using ambulatory methods for 1 day of monitoring, the authors of this study investigated the association between smoking and situational cues in 63 smokers with posttraumatic stress disorder (PTSD) and 32 smokers without PTSD. Generalized estimating equations contrasted 682 smoking and 444 nonsmoking situations by group status. Smoking was strongly related to craving, positive and negative affect, PTSD symptoms, restlessness, and several situational variables among PTSD smokers. For non-PTSD smokers, the only significant antecedent variables for smoking were craving, drinking coffee, being alone, not being with family, not working, and being around others who were smoking. These results are consistent with previous ambulatory findings regarding mood in smokers but also underscore that, in certain populations, mood and symptom variables may be significantly associated with ad lib smoking.

The present investigation examined the relations among posttraumatic stress symptoms and smoking motives. Participants included 100 daily smokers recruited from the community and university settings who reported exposure to at least one traumatic event that met criterion A for posttraumatic stress disorder. Consistent with prediction, higher levels of posttraumatic stress symptoms were associated with smoking to reduce negative affect; this

Smoking topography was measured in trauma survivors with and without posttraumatic stress disorder (PTSD) after recalling trauma-related and neutral experiences. Analysis of covariance was performed on puff topography and mood measures using nicotine dependence scores and current major depressive disorder as covariates. Puff volumes were higher in the PTSD group than in the non-PTSD group. The PTSD group exhibited stable puff onset intervals while the non-PTSD group exhibited significantly shorter intervals following trauma recall. These findings support a ''ceiling effect'' hypothesis in which individuals with PTSD perpetually smoke in such a way as to maximize nicotine delivery, possibly reducing the potentially reinforcing effects of increased smoke delivery in negative affect-inducing situations.

The present investigation examined intrinsic and extrinsic reasons for quitting among daily cigarette smokers with posttraumatic stress disorder (PTSD) as compared to clinical daily smokers with other anxiety and mood disorders (AM) and daily smokers with no current axis I psychopathology (C) prior to a self-guided quit attempt. It was hypothesized that (1) the PTSD group would report greater intrinsic (i.e., self-control and health concerns) reasons for quitting smoking, and (2) among those with PTSD, anxiety sensitivity (fear of anxiety; AS) would predict greater intrinsic reasons for quitting smoking. Participants were 143 (58.7% female; M age = 29.66 years, SD = 11.88) daily cigarette smokers. Partially consistent with prediction, the PTSD group reported significantly greater self-control intrinsic reasons for quitting, but not health concern intrinsic reasons, than the C group (p <.01). The PTSD group also reported greater immediate reinforcement extrinsic reasons for quitting than the C group (p <.05). The PTSD and AM groups did not significantly differ on any reasons for quitting. Also partially consistent with hypotheses, higher levels of anxiety sensitivity in daily smokers with axis I psychopathology (both PTSD and AM groups) significantly predicted greater self-control intrinsic reasons for quitting. AS did not significantly predict immediate reinforcement extrinsic reasons for quitting. The current findings suggest that individuals with PTSD and other psychopathology may have unique motivations for quitting smoking that could be usefully explored within smoking cessation treatment programs.
Smoking in Vietnam combat veterans with post-traumatic stress disorder
Journal of Traumatic Stress, 1995
The present study investigated smoking prevalence, smoking motives, demographic variables and psychological symptoms in 124 help-seekin~ male Vietnam combat veterans with post-traumatic stress disorder (PTSD). A high percentage of these veterans smoked (60%). Vietnam veterans with PTSD who smoked were more likely than those who did not smoke to report higher levels of PTSD symptoms, depression and trait anxiety. Increased depression was associated with increased automatic smoking. Smokers reported a high frequency of smoking in response to military memories. Implications for smoking interventions, cessation, and relapse prevention efforts are discussed.

The current study tested the emotional reactivity of smokers with and without histories of major depression (MDD Hx) and trauma exposure (TE). Four counterbalanced conditions nested negative (e.g., dysphoric) or neutral mood inductions with in vivo versus control smoking paraphernalia cues (Neutral+Control; Neutral+Cigarette; Neg+Control; Neg+Cigarette). Mixed model analysis of covariance (ANCOVA) tested between and within subjects differences in negative affective symptoms pre-to post-exposure across four groups (TE+MDD Hx; TE only; MDD Hx only; no history). Results produced two notable effects. First, TE only individuals endorsed the greatest increase in depressive symptoms across both negative mood induction conditions (regardless of smoking paraphernalia) compared with other groups. Second, dual history participants (TE+MDD Hx) show a potentiated depressive response to the Neg+Cigarette condition compared with the Neg+Control condition. Implications to a depression-specific negative affective vulnerability among TE only smokers that is independent of MDD Hx and greater than smokers with a MDD Hx are discussed.

The association between emotional numbing and heavy daily smoking suggests that veterans with PTSD may smoke to overcome emotional blunting following trauma exposure. Despite the strong association between smoking and PTSD, mechanisms infl uencing likelihood of smoking and smoking heaviness in this population remain unclear. Previous research has largely examined associations between PTSD and smoking

This study investigated the relationship between a trauma-related stressor and smoking withdrawal symptoms in 25 male Vietnam combat veterans with posttraumatic stress disorder (PTSD) using a within-subjects design. All subjects were smokers. The stressor involved a modified Stroop task. in which the veterans color-named either anxietyrelated or neutral control words. Anxiety-related words produced more withdrawal symptoms than neutral control words, including increased craving, negative affect symptoms. somatic symptoms, and lack of alertness. 93

The present investigation compared 123 community-recruited daily smokers with posttraumatic stress disorder (PTSD), panic disorder (PD), nonclinical panic attacks (PA), or no current Axis I psychopathology (controls; C) in terms of nicotine dependence, smoking rate, quit history, severity of symptoms during past quit attempts, and motivation for and expectancies about smoking. No differences were observed between groups in regard to smoking rate or nicotine dependence. The PTSD group reported making more lifetime quit attempts than the other groups, and the PTSD and PD groups perceived more severe symptoms during past quit attempts. The PD and PTSD groups reported greater motivation to smoke to reduce negative affect. Individuals with PTSD endorsed a stronger expectation that smoking would alleviate negative mood states and would produce negative consequences. Overall, results suggest that smokers with PD or PTSD differ from other smoking groups in a number of clinically significant ways. #
