Tobacco dependence is associated with increased risk for multi-morbid clustering of posttraumatic stress disorder, depressive disorder, and pain among post-9/11 deployed veterans.

Rationale: Tobacco use is highly prevalent among individuals with posttraumatic stress disorder (PTSD), depressive disorders, and pain. Research has revealed pairwise relationships among these conditions but has not examined more complex relationships that may influence symptom severity, chronicity, and treatment outcome.

Objective: To examine the clustering of current PTSD, depressive disorders, and clinically significant pain according to current tobacco use and dependence among post-9/11 deployed veterans.

Sweat pore reactivity as a surrogate measure of sympathetic nervous system activity in trauma-exposed individuals with and without posttraumatic stress disorder.

Stress analysis by FLIR (forward-looking infrared) evaluation (SAFE) has been demonstrated to monitor sweat pore activation (SPA) as a novel surrogate measure of sympathetic nervous system (SNS) activity in a normal population. SNS responses to a series of 15 1-s, 82 dB, white noise bursts were measured by skin conductance (SC) and SAFE monitoring of SPA on the fingers (FiP) and face (FaP) in 10 participants with posttraumatic stress disorder (PTSD) and 16 trauma-exposed participants without PTSD (Mage  = 48.92 ± 12.

The relationship between reward-based learning and nicotine dependence in smokers with schizophrenia.

Cigarette smoking rates remain remarkably high in schizophrenia relative to smoking in other psychiatric groups. Impairments in the reward system may be related to elevated rates of nicotine dependence and lower cessation rates in this psychiatric group. Smokers with schizophrenia and schizoaffective disorder (SWS; n=15; M(age)=54.

Utilizing reliable and clinically significant change criteria to assess for the development of depression during smoking cessation treatment: the importance of tracking idiographic change.

Studies typically measure mood changes during smoking cessation treatment in two ways: (a) by tracking mean change in depression scores or (b) by tracking the incidence of major depression development using diagnostic assessments. However, tracking mean change does not capture variability in individual mood trajectories, and diagnosing participants at multiple time points is time and labor intensive. The current study proposes a method of assessing meaningful increases in depression without the use of diagnostic assessments by utilizing reliable and clinically significant change criteria.

Risk perception in smokers with children with asthma.

Objective: No studies have examined the relationship between caregiver beliefs about the risks of smoking to their own health and caregiver beliefs about the effect of their smoking on their child's health. In the current study, we investigated our proposed risk congruence hypothesis among caregivers who smoke. Specifically, we investigated whether caregivers' self-perceived risk of smoking is directly associated with their perception of the risks of smoking to their child.

Anxiety sensitivity and perceived control over anxiety-related events: evaluating the singular and interactive effects in the prediction of anxious and fearful responding to bodily sensations.

The present investigation examined the singular and interactive effects of anxiety sensitivity and perceived control over anxiety-related events in the prediction of panic symptoms using a CO(2)-enriched air biological challenge. Two hundred and twenty-nine adult participants (M(age)=21.02, SD=7.

Anxiety sensitivity and perceived control over anxiety-related events: associations with smoking outcome expectancies and perceived cessation barriers among daily smokers.

The present investigation examined the extent to which the cognitive factors of anxiety sensitivity (AS) and perceived control over anxiety-related events are independently related to smoking outcome expectancies and perceived barriers to quitting. Participants were 125 community-recruited adult, daily smokers. Consistent with hypotheses, AS and perceived control over anxiety-related events independently and significantly predicted smokers' expectancies for negative affect reduction from smoking, whereas only AS predicted expectancies for negative personal consequences from smoking.

Incremental validity of anxiety sensitivity in terms of motivation to quit, reasons for quitting, and barriers to quitting among community-recruited daily smokers.

The present investigation examined the relationships between anxiety sensitivity and motivation to quit smoking, barriers to smoking cessation, and reasons for quitting smoking among 329 adult daily smokers (160 females; M (age) = 26.08 years, SD = 10.92).

Concurrent associations between anxiety sensitivity and perceived health and health disability among young adult daily smokers.

The aim of this investigation was to evaluate the incremental validity of anxiety sensitivity (fear of arousal-related physical and psychological sensations) relative to health factors (smoking variables, alcohol use and exercise level), in predicting perceived health and disability among a sample of 225 young adult daily smokers (102 females; M(age) = 23.9 years, SD = 8.8).

Perceived health among individuals with panic disorder: associations with affective vulnerability and psychiatric disability.

The present investigation evaluated the predictive nature of perceived physical health in relation to affective vulnerability and psychiatric disability among individuals with panic disorder. Participants included 39 individuals (Mage = 25.86; 69% female) with a primary diagnosis of panic disorder (with and without agoraphobia) recruited through the general community.
