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(More)
The study investigated the effects of smoking a nicotinized or denicotinized cigarette on craving, affect and posttraumatic stress disorder (PTSD) symptoms while recalling neutral, stressful and traumatic events in smokers with and without PTSD. Smokers completed laboratory sessions during which they were presented with audiotapes of personalized scripts(More)
An examination of the relationships between health behaviors (preventive and risk-related), physician-diagnosed medical problems, role-functioning impairment because of physical morbidity, and post-traumatic stress disorder was conducted on a large cohort of consecutive treatment-seeking cases (N = 826) presenting to an outpatient Veterans Affairs(More)
Rates of smoking among individuals with psychiatric conditions are greater than rates seen in the general population, yet little is known about the psychometric properties of commonly used nicotine dependence instruments among psychiatric smokers. This study examined the reliability, validity, and factor structure of the Fagerström Test for Nicotine(More)
The authors examined competing hypotheses regarding the role of 2 personality dimensions, disconstraint and negative emotionality, in mediating the relationship between posttraumatic stress disorder (PTSD) severity and substance-related problems. Data were drawn from a large sample of male Vietnam veterans. The best-fitting structural model included(More)
This study investigated the associations among PTSD, ambulatory cardiovascular monitoring, and physical health self-reports in 117 male Vietnam combat veterans (61 with PTSD and 56 without PTSD). PTSD was associated with health symptoms and number of current health conditions beyond the influence of several covariates. PTSD was associated with greater(More)
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(More)
Rates of smoking among individuals with psychiatric conditions are much greater than those seen in the general population, yet little is known about the psychometric properties of commonly used instruments that assess smoking-related variables among smokers with psychiatric conditions. The present study examined the factor structure and psychometric(More)
Rates of smoking among populations with psychiatric disorders are more than twice as high as among the general population, yet there are few controlled studies of the mechanisms of this relationship. This trial examined the effect of nicotine by way of cigarette smoking on both self-report and autonomic parameters of anxiety among individuals with PTSD who(More)
