Adult male alcoholics in treatment (n = 30) were randomly assigned to visual and olfactory exposure either to alcohol cues or to control cues, and then were allowed to smoke while continuing visual exposure to the same cues. Exposure to alcohol cues resulted in significantly greater self-reported urge to drink and urge to smoke but had no significant effect on the topography of smoking behavior. When variance due to urge to smoke was controlled, greater urge to drink correlated negatively with number of cigarette puffs. The results provide some support for a priming hypothesis of tobacco's role on alcoholism recovery. Clinical and theoretical implications are discussed.

Both are associated with posttraumatic stress disorder (PTSD) and may be related to functional disability. Although self-compassion includes mindful awareness of emotional distress, it is a broader construct that also includes being kind and supportive to oneself and viewing suffering as part of the shared human experience-a potentially powerful way of dealing with distressing situations. We examined the association of mindfulness and self-compassion with PTSD symptom severity and functional disability in 115 trauma-exposed U.S. Iraq/Afghanistan war veterans. Mindfulness and self-compassion were each uniquely, negatively associated with PTSD symptom severity. After accounting for mindfulness, self-compassion accounted for unique variance in PTSD symptom severity (f(2) = .25; medium ES). After accounting for PTSD symptom severity, mindfulness and self-co...

The aim of the present study was to investigate the effects of CET and CST in a larger controlled study when both were added to intensive treatment programs. A 2 x 2 design investigated the effects of CET with urge coping skills training compared to a meditation-relaxation control, and CST compared to an education control when all were added to intensive treatment programs for alcoholics. The sites were the inpatient or partial hospital substance abuse treatment programs at a private psychiatric hospital, a state-funded residential facility and a VA medical center. Patients diagnosed with alcohol dependence without active psychosis were eligible. Participants were assessed for quantity and frequency of drinking, alcohol cue-reactivity, responses to high risk simulations and urge specific ...

Each condition is associated with disability, particularly when co-occurring. Pain acceptance is a strong predictor of lower levels of disability in chronic pain. This study examined whether acceptance of pain predicted current and future disability beyond the effects of these co-occurring conditions in war veterans. Eighty trauma-exposed veterans with chronic pain completed a PTSD diagnostic interview, clinician-administered mTBI screening, and self-report measures of disability, pain acceptance, depression, and alcohol use. Hierarchical regression models showed pain acceptance to be incrementally associated with disability after accounting for symptoms of PTSD, depression, alcohol-related problems, and mTBI (total adjusted R(2) = .57, p < .001, ΔR(2) = .03, p =...

Further, the co-occurrence of Substance Use Disorders (SUD; i.e., alcohol and/or other drug abuse or dependence) has frequently been identified as a prognosticator of poor physical and psychological health as well as poor treatment and functional outcomes for individuals with PTSD (e.g., Ouimette, Goodwin & Brown, 2006; Jacobsen, Southwick, & Kosten, 2001). The goals of the current chapter are to: (1) provide a brief summary of the evidence of co-occurrence of PTSD and SUD within military, veteran, and civilian populations; (2) evaluate the gold-standard assessments for substance use and diagnosis of SUD; (3) review published treatment strategies for these co-occurring conditions; and (4) discuss the implications of the co-occurrence of P...

After accounting for the possible influence of combat exposure, we expected that the resilient prototype would predict lower depression and PTSD over time and would be associated with adaptive coping strategies, higher social support, lower psychological inflexibility, and higher self-reported resilience relative to overcontrolled and undercontrolled prototypes, independent of traumatic brain injury (TBI) status. One hundred twenty-seven veterans (107 men, 20 women; average age = 37) participated in the study. Personality was assessed at baseline, and PTSD and depression symptoms were assessed 8 months later. Path analysis was used to test the direct and indirect effects of personality on distress. No direct effects were observed from personality to distress. The resilient prototype did have significant indirect effects on PTSD and depression through its beneficial effects on social support, coping and psychological inflexibility. TBI also had direct effects on PTSD. A resilient personality prototype appears to influence veteran adjustment through its positive associations with greater social support and psychological flexibility, and lower use of avoidant coping. Low social support, avoidant coping, and psychological inflexibility are related to overcontrolled and undercontrolled personality prototypes, and these behaviors seem to characterize veterans who experience problems with depression and PTSD over time. A positive TBI status is directly and prospectively associated with PTSD symptomology independent of personality prototype. Implications for clinical interventions and future research are discussed.

Each trial consisted first of a randomized crossover period of 1 day of decaffeinated coffee and 1 day of caffeinated coffee (100 mg) to assess withdrawal and adverse effects of caffeine. Next, subjects were given 2 days of concurrent access to the two coffees. The relative use of the two coffees was used to assess caffeine self-administration. Reliable caffeine self-administration occurred in three of 10 subjects in study 1 and seven of 12 subjects in study 2. Withdrawal symptoms were headaches, drowsiness, and fatigue. The major adverse effect from self-administration was tremulousness. The occurrence of headaches on substitution of decaffeinated coffee prospectively predicted subsequent self-administration of caffeine. These results indicate that some coffee drinkers exhibit signs of a caffeine dependence, ie, t...

The present study of alcoholics in treatment for alcoholism extended previous work by investigating the cross-sectional and longitudinal relationships between drinking and smoking variables. Male and female alcoholics (N = 116) completed a standard assessment of smoking and drinking pretreatment followed by a laboratory assessment of reactivity to alcohol cues. Participants' drinking and smoking were evaluated again 6 months following treatment. (1) Pretreatment tobacco dependence, pretreatment alcohol dependence, urge to smoke and urge to drink were positively correlated; (2) smoking rates and drinking rates were not correlated either before or following treatment; (3) pretreatment smoking history did not predict posttreatment drinking; (4) the rate of smoking declined following treatment for alcoholism for 45% of the smoking patients who completed a 6-mo...

Twenty-four male alcoholic patients responded to a series of computer-generated tones as rapidly as possible during baseline and again during either an alcohol cue exposure period or exposure to a control beverage (water). Patients required increased time to respond to the tones when exposed to alcohol cues. No such increase in RT was found during exposure to a control beverage. In addition, RT was significantly correlated with self-reported urge to drink. These data provide initial validation for the use of RT as an objective measure of cue reactivity. Both theoretical and clinical implications for the use of RT as a measure of the effects of cue exposure are discussed.

The present study of alcoholics in treatment for alcoholism investigated pretreatment tobacco and alcohol history and dependence, as well as subjective responsivity to alcohol cues. Eighty-three male alcoholics underwent a questionnaire assessment of smoking and drinking pretreatment followed by a laboratory assessment of reactivity to alcohol cues. The analyses demonstrate that (1) pretreatment tobacco dependence and pretreatment alcohol dependence are related, (2) alcohol dependence predicts urges to smoke during alcohol treatment, (3) exposure to alcohol cues results in increased urge to smoke, (4) smoking when ill predicts urge to drink during alcohol cue exposure and (5) urge to smoke is positively correlated with urge to drink. These data, collected in a population of alcoholics not currently receiving smoking interventions, indicate that smoking may be a factor to addres...

Compelling theories of how smoking becomes compulsive exist but are largely based on extrapolation from neuroscience findings. Research on smokers is impeded, in part, by a lack of instruments that specifically measure compulsive smoking. Objective This study evaluated the measurement structure and validity of the Obsessive Compulsive Smoking Scale (OCSS), a ten-item questionnaire designed to measure compulsive smoking. Methods Participants were 239 daily smokers (≥1 cigarette/ day), including 142 students at a public university in Chicago and 97 veterans treated at the VA Boston Health-care System. The OCSS and questionnaires measuring current and past smoking, cigarette craving, automatic smoking, and nicotine dependence were administered. Results Factor analysis with maximum likelihood extraction and oblique rotation revealed two correlated underlying factors, interpreted as "Preoccupation with Smoking" and "Compulsive Drive." The measurement structure was consistent across students and veterans, and confirmed in an independent sample of adults (n=95). Veterans exhibited higher OCSS scores (full scale and subscales) than students. Across groups, higher OCSS scores were positively correlated with smoking intensity, craving, and nicotine dependence. OCSS full-scale and compulsive drive scores, but not smoking preoccupation scores, were inversely

The psychometric properties of the CWE were evaluated across three independent samples of Iraq/Afghanistan veterans. Despite its brevity (7 items), the CWE exhibited good internal consistency (average α =0.83), good temporal stability (1-year test-retest reliability=0.73), good concurrent validity with lengthier measures of warzone experiences (average r=0.74), and a clear unidimensional factor structure (average factor loading=0.69). Study 2 confirmed the CWE׳s factor structure through confirmatory factor analysis, and structural equation modeling demonstrated a strong association between CWE and post-deployment mental health, β =0.49, p&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;lt;0.001. Study 3 provided further support for the predictive validity of the CWE by demonstrating that it was associated with PTSD diagnosis, clinician-rated PTSD symptom severity, and global functional impairment in an independent sample of Iraq/Afghanistan veterans (average r=0.59). While replication of these findings in more diverse samples is needed, the preliminary evidence from these studies indicates that the CWE is a brief, reliable, and valid measure of critical warzone experiences among Iraq/Afghanistan war veterans.

We hypothesized that avoidant and action-oriented coping styles would moderate the association between PTSD symptom severity and alcohol outcomes among U.S. Operation Enduring Freedom/Operation Iraqi Freedom veterans, such that PTSD symptoms would be most strongly and positively associated with negative alcohol-related consequences and drinking quantity when action-oriented coping was low and avoidant coping was high. The sample (N = 128; 85.2% male, M = 37.8 years old, 63.3% Caucasian) completed a diagnostic assessment for PTSD and AUD and self-report surveys measuring coping styles, drinking quantity, and negative alcohol-related consequences. Consistent with the main hypothesis, a 3-way interaction among PTSD symptom severity, avoidant coping, and action-oriented coping was found in the predicted direction (d = 0.47-0.55). Post hoc descriptive analyses indicated that veterans with a current diagnosis of PTSD, low action-oriented coping, and high avoidant coping had worse alcohol outcomes and were twice as likely to meet criteria for current AUD compared with veterans with fewer risk factors. Findings suggest that the combination of PTSD and maladaptive coping styles may be more important for understanding alcohol-related outcomes than the presence of any of these variables in isolation.

One hundred forty-nine alcohol-dependent patients completed a 3-month randomized, controlled trial of BST and naltrexone versus MET and naltrexone. Patients receiving BST had a significantly higher percentage of days abstinent than patients receiving MET. The superior effect of BST is particularly strong in interaction with support for drinking, suggesting that the advantage of BST is worth the additional cost for patients whose psychosocial networks are supportive of continued drinking. This effect remains significant when controlling for pretreatment percentage of days abstinent. In aggregate, these findings suggest that it is either the combination of naltrexone and BS...
