RESUMEN

BACKGROUND: Intimate partner violence (IPV) against women is a global health problem that is a substantial source of human suffering. Within the United States (US), women veterans are at high risk for experiencing IPV. There is an urgent need for feasible, acceptable, and patient-centered IPV counseling interventions for the growing number of women treated in the US's largest integrated healthcare system, the Veterans Health Administration (VHA). Implementation science and user-centered-design (UCD) can play an important role in accelerating the research-to-practice pipeline. Recovering from IPV through Strengths and Empowerment (RISE) is a flexible, patient-centered, modular-based program that holds promise as a brief counseling intervention for women veterans treated in VHA. We utilized a UCD approach to develop and refine RISE (prior to formal effectiveness evaluations) by soliciting early feedback from the providers where the intervention will ultimately be implemented. The current study reports on the feedback from VHA providers that was used to tailor and refine RISE. METHOD: We conducted and analyzed semi-structured, key-informant interviews with VHA providers working in clinics relevant to the delivery of IPV interventions (n = 23) at two large medical centers in the US. Participants' mean age was 42.6 years (SD = 11.6), they were predominately female (91.3%) and from a variety of relevant disciplines (39.1% psychologists, 21.7% social workers, 17.4% physicians, 8.7% registered nurses, 4.3% psychiatrists, 4.3% licensed marriage and family therapists, 4.3% peer specialists). We conducted rapid content analysis using a hybrid inductive-deductive approach. RESULTS: Providers perceived RISE as highly acceptable and feasible, noting strengths including RISE's structure, patient-centered agenda, and facilitation of provider comfort in addressing IPV. Researchers identified themes related to content and context modifications, including requests for additional safety check-ins, structure for goal-setting, and suggestions for how to develop and implement RISE-specific trainings. CONCLUSIONS: These findings have guided refinements to RISE prior to formal effectiveness testing in VHA. We discuss implications for the use of UCD in intervention development and refinement for interventions addressing IPV and other trauma in health care settings globally.

RESUMEN

Tonic immobility (TI) is an involuntary freezing response that can occur during a traumatic event. TI has been identified as a risk factor for posttraumatic stress disorder (PTSD), although the mechanism for this relationship remains unclear. This study evaluated a particular possible mechanism for the relationship between TI and PTSD symptoms: posttraumatic guilt. To examine this possibility, we assessed 63 female trauma survivors for TI, posttraumatic guilt, and PTSD symptom severity. As expected, the role of guilt in the association between TI and PTSD symptom severity was consistent with mediation (B = 0.35; p < .05). Thus, guilt may be an important mechanism by which trauma survivors who experience TI later develop PTSD symptoms. We discuss the clinical implications, including the importance of educating those who experienced TI during their trauma about the involuntary nature of this experience.

RESUMEN

Prepulse inhibition (PPI) is a measure of sensorimotor filtering thought to shield the processing of initial weaker auditory stimuli from interruption by a later startle response. Previous studies have shown smoking withdrawal to have a negative impact on sensorimotor filtering, particularly in individuals with psychopathology. Because tobacco use may alleviate sensory and sensorimotor filtering deficits, we examined whether smoking withdrawal-induced changes in PPI were associated with maintenance of smoking abstinence in trauma-exposed individuals with and without PTSD who were attempting to quit smoking. Thirty-eight individuals (n = 24 with current or past PTSD; 14 trauma-exposed healthy controls) made an acute biochemically-verified smoking cessation attempt supported by 8 days of contingency management (CM) and cognitive behavioral therapy (CBT) for smoking. Participants completed a PPI task at the pre-quit baseline, 2 days post-quit, and 5 days post-quit. Post-quit changes in PPI were compared between those who remained abstinent for the first 8-days of the quit attempt and those who lapsed back to smoking. PPI changes induced by biochemically-verified smoking abstinence were associated with maintenance of abstinence across the 8-day CM/CBT-supported quit attempt. As compared to those who maintained tobacco abstinence, participants who lapsed to smoking had significantly lower PPI at 2 and 5 days post-quit relative to baseline. Thus, among trauma-exposed individuals, decreases in PPI during acute smoking cessation supported by CM/CBT are associated with lapse back to smoking. Interventions that improve PPI during early smoking abstinence may facilitate smoking cessation among such individuals who are at high risk for chronic, refractory tobacco use.

RESUMEN

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)=54.87, S.D.=6.51, 100% male) and a non-psychiatric control group of smokers (NCL; n=16; M(age)=50.38, S.D.=11.52; 93.8% male) were administered a computerized signal detection task to measure reward-based learning. Performance on the signal detection task was assessed by response bias, discriminability, reaction time, and hit rate. Clinician-assessed and self-reported measures of smoking and psychiatric symptoms were completed. SWS exhibited similar patterns of reward-based learning compared to control smokers. However, decreased reward-based learning was associated with increased levels of nicotine dependence in SWS, but not among control smokers. Nicotine withdrawal and urge to smoke were correlated with anhedonia within the SWS group. Among SWS, reduced reward responsiveness and increased anhedonia were associated with and may contribute to greater co-occurring nicotine dependence. These findings emphasize the importance of targeting reward system functioning in smoking cessation treatment for individuals with schizophrenia.

RESUMEN

Few studies examine predictors of smoking cessation among medically ill smokers, despite their high smoking prevalence. We prospectively examined barriers to smoking cessation in medically ill smokers, with age as a hypothesized moderator. Participants were smokers (N = 237, M (age) = 56.1, 53.6% females) receiving home-based nursing care. Baseline self-report questionnaires assessed barriers to cessation (demographics, smoking history, psychosocial, and medical factors). Smoking status was biochemically verified at 2- and 6-months post-intervention. Compared with younger smokers, older smokers had significantly lower levels of nicotine dependence, stress, and depressed mood and a greater prevalence of smoking-related diseases. Older smokers were more likely to achieve biochemically verified abstinence at 6-month follow-up (7.8%) than younger smokers (3.1%) though this difference was not significant. Higher levels of depressed mood and lower levels of perceived stress were associated with a greater likelihood of cessation at both follow-up points, but only for younger smokers. For younger smokers, higher self-efficacy to quit and the presence of a smoking-related disease increased the odds of abstinence. These findings could help guide treatment development for this high-risk group of smokers.

RESUMEN

The present investigation examined heart-focused anxiety and perceived physical health in terms of affect-relevant cigarette smoking motives and outcome expectancies. Participants were a community sample of 140 adult daily smokers (81 women, mean age = 29.60 years, SD = 11.98). In terms of smoking motives, both heart-focused anxiety and perceived physical health incrementally predicted smoking for negative affect reduction motives above and beyond relevant covariates (gender, weekly alcohol consumption, daily smoking rate). Yet heart-focused anxiety, but not perceived physical health, was incrementally predictive of habitual motives, relative to the same covariates. With regard to smoking outcome expectancies, heart-focused anxiety was incrementally predictive of negative reinforcement outcome expectancies, whereas perceived physical health was not. Alternatively, perceived physical health was incrementally predictive of negative personal consequence outcome expectancies, but heart-focused anxiety was not. Findings are discussed in relation to the role of perceived health vulnerabilities in clarifying affect-oriented smoking motives and expectancies.

RESUMEN

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. METHODS: Logistic regression was used to examine the clustering of these conditions in relationship to current tobacco use/dependence, while adjusting for age and total combat exposure, in 343 post-9/11 deployed veterans enrolled in the Translational Research Center for TBI and Stress Disorders (TRACTS) cohort (Mage = 32.1 + 8.3 years; 38% current tobacco use; 25% low and 12% moderate/high tobacco dependence). RESULTS: A three-way clustering of PTSD, depressive disorder, and pain was more likely than any single or pairwise combination of these conditions in moderate/high tobacco-dependent veterans compared to tobacco non-users (adjusted ORs = 3.50 to 4.18). This multi-morbidity cluster also was associated with increased PTSD severity. CONCLUSIONS: Moderate to high dependence on tobacco is associated with substantially increased clustering of PTSD, depression, and clinically significant pain in veterans. Research examining synergistic interactions among these conditions, biological vulnerabilities shared among them, and the direct impact of tobacco use on the pathophysiology of PTSD, depression, and pain is needed. The results of such work may spur development of more effective integrated treatments to reduce the negative impact of these multi-morbid conditions on veterans' wellbeing and long-term health.

RESUMEN

Allopregnanolone and pregnanolone (together termed allo + pregnan) are neurosteroid metabolites of progesterone that equipotently facilitate the action of gamma-amino-butyric acid (GABA) at GABAA receptors. The adrenal steroid dehydroepiandrosterone (DHEA) allosterically antagonizes GABAA receptors and facilitates N-methyl-D-aspartate (NMDA) receptor function. In prior research, premenopausal women with posttraumatic stress disorder (PTSD) displayed low cerebrospinal fluid (CSF) levels of allo + pregnan [undifferentiated by the gas chromatography-mass spectrometry (GC-MS) method used] that correlated strongly and negatively with PTSD reexperiencing and negative mood symptoms. A PTSD-related decrease in the ratio of allo + pregnan to 5α-dihydroprogesterone (5α-DHP: immediate precursor for allopregnanolone) suggested a block in synthesis of these neurosteroids at 3α-hydroxysteroid dehydrogenase (3α-HSD). In the current study, CSF was collected from unmedicated, tobacco-free men with PTSD (n = 13) and trauma-exposed healthy controls (n = 17) after an overnight fast. Individual CSF steroids were quantified separately by GC-MS. In the men with PTSD, allo + pregnan correlated negatively with Clinician-Administered PTSD Scale (CAPS-IV) total (ρ=-0.74, p = 0.006) and CAPS-IV derived Simms dysphoria cluster (ρ=-0.71, p = 0.01) scores. The allo+pregnan to DHEA ratio also was negatively correlated with total CAPS (ρ=-0.74, p = 0.006) and dysphoria cluster (ρ=-0.79, p = 0.002) scores. A PTSD-related decrease in the 5α-DHP to progesterone ratio indicated a block in allopregnanolone synthesis at 5α-reductase. This study suggests that CSF allo + pregnan levels correlate negatively with PTSD and negative mood symptoms in both men and women, but that the enzyme blocks in synthesis of these neurosteroids may be sex-specific. Consideration of sex, PTSD severity, and function of 5α-reductase and 3α-HSD thus may enable better targeting of neurosteroid-based PTSD treatments.

RESUMEN

INTRODUCTION: Trauma-exposed individuals with and without posttraumatic stress disorder (PTSD) are more likely to smoke and less successful in quit attempts than individuals without psychopathology. Contingency management (CM) techniques (i.e., incentives for abstinence) have demonstrable efficacy for smoking cessation in some populations with psychopathology, but have not been well tested in PTSD. This pilot study examined the feasibility of CM plus brief cognitive behavioral therapy (CBT) in promoting smoking cessation among trauma-exposed individuals with and without PTSD. METHODS: Fifty trauma-exposed smokers (18 with PTSD) were asked to abstain from tobacco and nicotine replacement therapy for one month. During week one of cessation, CBT was provided daily and increasing CM stipends were paid for each continuous day of biochemically-verified abstinence; CM stipends were withheld in response to smoking lapses and reset to the initial payment level upon abstinence resumption. CBT and fixed payments for study visits were provided during the subsequent three weeks. RESULTS: Of the 50 eligible participants who attended at least one pre-quit visit (49% female, 35% current PTSD), 43 (86%) attended the first post-quit study visit, 32 (64%) completed the first week of CM/CBT treatment, and 26 (52%) completed the study. Post-quit seven-day point prevalence abstinence rates for participants with and without PTSD, respectively, were similar: 39% vs. 38% (1 week), 33% vs. 28% (2 weeks), 22% vs. 19% (3 weeks), and 22% vs. 13% (4 weeks). CONCLUSIONS: Use of CM + CBT to support tobacco abstinence is a promising intervention for trauma-exposed smokers with and without PTSD.

RESUMEN

The present investigation examined the extent to which panic reactivity to bodily sensations is related to distress tolerance (DT) among daily smokers. It was hypothesized that panic reactivity to an initial voluntary hyperventilation (i.e., whether participants met criteria for a DSM-IV panic attack; PA) would predict the relative degree of task persistence on a second hyperventilation trial (DT) above and beyond the variance accounted for by anxiety sensitivity (AS), negative affectivity (NA), cigarette smoking rate, and self-reported discomfort intolerance (DI). Participants were 95 daily smokers (58% women; M-sub(age) = 29.0, SD = 12.2) who completed a battery of questionnaires and two voluntary hyperventilation procedures. Results indicated PA status significantly predicted DT, above and beyond the theoretically relevant covariates of AS, NA, cigarettes per day, and DI ( p < .05). Such a result is consistent with theoretical models and empirical findings on emotional reactivity that suggest panic responsivity to internal cues may represent a key explanatory construct in terms of level of DT to interoceptive stimuli.

RESUMEN

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.

RESUMEN

The primary aim of this study was to examine whether smoking to reduce negative affect was uniquely related to a range of affective vulnerability factors (e.g., anxiety sensitivity, anxious arousal, and negative affectivity) among daily smokers. Participants were 276 young adult daily smokers (124 females; M(age)=25.12, SD=10.37). Partially consistent with prediction, the motivation to smoke to reduce negative affect was significantly related to anxiety sensitivity and negative affectivity, but not anxious arousal; the observed significant effects were above and beyond other theoretically relevant factors (e.g., smoking rate, years smoked, age, gender). In contrast to prediction, habitual smoking motives demonstrated significant incremental associations with anxiety sensitivity and anxious arousal symptoms. These results suggest that there are important associations between certain smoking motives and negative affective states and that such relations are not attributable to other smoking factors (e.g., smoking rate).

RESUMEN

The present study evaluated the association between the lower-order facets of Anxiety Sensitivity construct (Physical, Mental Incapacitation and Social Concerns) and theoretically relevant cognitive-based smoking processes. Participants were 151 young adult daily smokers (63 females); mean number of cigarettes/day = 12.3 [S.D. = 5.6]). Both AS Physical and Mental Incapacitation Concerns were significantly associated with greater negative affect reduction smoking motives and lower levels of self-confidence in remaining abstinent from smoking when emotionally distressed. The observed effects were over and above the variance accounted for by nicotine dependence, smoking rate, and gender. Results are discussed in relation to better understanding cognitive-based smoking processes among individuals at heightened risk for panic psychopathology.

RESUMEN

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 ± 12.00 years; 26.9% female). Within participants, SC and FiP responses across trials were strongly correlated (r = .92, p < .001). Correlations between SC and FaP (r = .76, p = .001) and between FiP and FaP (r = .47, p = .005) were smaller. The habituation of SNS responses across the 15 trials was substantial (SC: d = -2.97; FiP: d = -2.34; FaP: d = -1.02). There was a strong correlation between habituation effects for SC and FiP (r = .76, p < .001), but not for SC and FaP (r = .15, p = .45) or FiP and FaP (r = .29, p = .16). Participants with PTSD showed larger SNS responses to the first loud noise than those without PTSD. PTSD reexperiencing symptoms assessed by the PTSD Checklist on the day of testing were associated with the SNS responses to the first loud noise measured by SC (d = 1.19) and FiP (d = .99), but not FaP (d = .10). This study confirms convergence of SAFE and SC as valid measures of SNS activity. SAFE FiP and SC responses were highly predictive of self-rated PTSD reexperiencing symptoms. SAFE may offer an attractive alternative for applications in PTSD and similar populations.

RESUMEN

OBJECTIVE: Epidemiological research has demonstrated that tobacco use and posttraumatic stress disorder (PTSD) frequently co-occur and are highly prevalent among Veterans; research with female Veterans is limited. Given the increasing numbers of women deployed to combat zones in recent conflicts, the objective of the current study was to examine gender-specific associations between deployment stress, tobacco use and postdeployment PTSD symptoms. METHOD: Two thousand thirteen Veterans deployed to Afghanistan and Iraq (50.9% female; mean age = 35.53) completed a postdeployment, mailed survey that assessed tobacco use before, during, and after deployment, deployment stressors, and postdeployment PTSD symptoms. RESULTS: Warfare stress was associated with initiation and increases in tobacco use during deployment in both men and women, whereas harassment stress was associated with initiation and increases in tobacco use in women only. Only among women was continued postdeployment tobacco use associated with postdeployment PTSD symptoms. CONCLUSIONS: We found a dose-dependent relationship between deployment stress and adoption and escalation of tobacco use; the stressors that provoked initiation and escalation of tobacco use differed by gender. Continued tobacco use after deployment was associated with PTSD in women suggesting that women used tobacco more selectively than men to regulate negative affect. Implications of this work are that training before combat and during combat on healthy means of coping with deployment stress is needed to prevent tobacco use. For women, reducing harassment stress during deployment and early treatment of acute stress and PTSD during and soon after deployment may prevent intractable tobacco use.

RESUMEN

Although previous work has found associations between panic and smoking, little research has investigated potential mechanisms by which smoking may contribute to panic problems. The present investigation evaluated the incremental validity of acute nicotine withdrawal symptoms (elicited by an average of 2h of nicotine deprivation) relative to negative affectivity, anxiety sensitivity, and nicotine dependence in predicting anxiety responding to 3-min voluntary hyperventilation. The sample consisted of 90 regular smokers (46 females), as defined by smoking >or= 10 cigarettes per day for at least 1 year, recruited through the general community. Consistent with prediction, greater levels of pre-challenge nicotine withdrawal symptoms uniquely predicted post-challenge intensity of panic symptoms and anxiety relative to other established factors. Findings are discussed in the context of how regular smoking may promote panic symptomotology.

RESUMEN

Chronic pain and posttraumatic stress disorder (PTSD) are disabling conditions that affect biological, psychological, and social domains of functioning. Clinical research demonstrates that patients who are affected by chronic pain and PTSD in combination experience greater pain, affective distress, and disability than patients with either condition alone. Additional research is needed to delineate the interrelated pathophysiology of chronic pain and PTSD, with the goal of facilitating more effective therapies to treat both conditions more effectively; current treatment strategies for chronic pain associated with PTSD have limited efficacy and place a heavy burden on patients, who must visit various specialists to manage these conditions separately. This article focuses on neurobiological factors that may contribute to the coprevalence and synergistic interactions of chronic pain and PTSD. First, we outline how circuits that mediate emotional distress and physiological threat, including pain, converge. Secondly, we discuss specific neurobiological mediators and modulators of these circuits that may contribute to chronic pain and PTSD symptoms. For example, neuropeptide Y, and the neuroactive steroids allopregnanolone and pregnanolone (together termed ALLO) have antistress and antinociceptive properties. Reduced levels of neuropeptide Y and ALLO have been implicated in the pathophysiology of both chronic pain and PTSD. The potential contribution of opioid and cannabinoid system factors also will be discussed. Finally, we address potential novel methods to restore the normal function of these systems. Such novel perspectives regarding disease and disease management are vital to the pursuit of relief for the many individuals who struggle with these disabling conditions.

RESUMEN

Intense subjective distress and physiologic reactivity upon exposure to reminders of the traumatic event are each diagnostic features of posttraumatic stress disorder (PTSD). However, subjective reports and psychophysiological data often suggest different conclusions. For the present study, we combined data from five previous studies to assess the contributions of these two types of measures in predicting PTSD diagnosis. One hundred fifty trauma-exposed participants who were classified into PTSD or non-PTSD groups based on structured diagnostic interviews completed the same script-driven imagery procedure, which quantified measures of psychophysiologic reactivity and self-reported emotional responses. We derived four discriminant functions (DiscFxs) that each maximally separated the PTSD from the non-PTSD group using (1) psychophysiologic measures recorded during personal mental imagery of the traumatic event; (2) self-report ratings in response to the trauma imagery; (3) psychophysiologic measures recorded during personal mental imagery of another highly stressful experience unrelated to the index traumatic event; and (4) self-report ratings in response to this other stressor. When PTSD status was simultaneously regressed on all four DiscFxs, trauma-related psychophysiological reactivity was a significant predictor, but physiological reactivity resulting from the highly stressful, but not traumatic script, was not. Self-reported distress to the traumatic experience and the other stressful event were both predictive of PTSD diagnosis. Trauma-related psychophysiologic reactivity was the best predictor of PTSD diagnosis, but self-reported distress contributed additional variance. These results are discussed in relation to the Research Domain Criteria framework.

RESUMEN

PURPOSE: No studies have examined the differences in smoking attitudes and behavior between Dominicans (DRs) and Puerto Ricans (PRs). Identification of pretreatment differences is important for cultural adaptation of evidenced-based smoking cessation treatments. DESIGN: Secondary analysis. SETTING/INTERVENTION: Three home visits for asthma education and smoking cessation. SUBJECTS: Caregivers who smoke and have a child with asthma: DRs (n = 30), PRs (n = 67), and non-Latino whites (n = 128; NLWs). MEASURES: Baseline assessment of psychosocial variables. ANALYSES: Controlled for age, education, and acculturation. RESULTS: Compared with DRs, PRs were more acculturated, more nicotine dependent, less motivated and confident to quit, and identified more pros of smoking (all p < .05). Compared with NLWs, PRs were less likely to be employed, smoked fewer cigarettes per day, and had lower education, greater depressed mood, greater pros and cons of smoking, less social support, and higher child asthma morbidity (all p < .05). Compared with NLWs, DRs were less nicotine dependent, more confident to quit, and less likely to live with a smoker; reported greater cons of smoking and greater stress; and were more likely to have a household smoking ban (DRs 60% vs. NLWs 33.6%). Only 3.3% of DRs were precontemplators vs. 16.4% (PRs) and 10.9% (NLWs). CONCLUSIONS: PRs appear to have more factors associated with risk of smoking treatment failure; DRs appear to have more protective factors. Examination of the role of these smoking attitudes as potential moderators and mediators of smoking behavior are needed to guide the cultural adaptation of evidenced-based treatments.
