Single-session anxiety sensitivity reduction program for trauma-exposed adults: a case series documenting feasibility and initial efficacy

Response and ongoing skills use following a single-session virtual cognitive behavioral workshop for graduate students

OBJECTIVE

Graduate students frequently experience anxiety, depression, and psychological distress. Counseling centers struggle to meet this need. Brief, skills-based treatments to mitigate burgeoning or mild mental health problems could alleviate this problem.

PARTICIPANTS

Participants were 51 graduate students in years one through seven of their respective programs.

METHODS

We examined a single-session virtual cognitive behavioral workshop and outcomes up to 6-months later.

RESULTS

The program was feasible, acceptable, and beneficial for mood, anxiety, and emotion regulation, even during the COVID-19 pandemic. A majority of participants reported ongoing skills use at follow-up. Primary barriers to more frequent use were forgetting, time constraints, and difficulty when experiencing strong emotions. Few participants endorsed expecting that skills would not be helpful or forgetting how to use skills.

CONCLUSIONS

This intervention may provide scalable, much needed aid to graduate schools. Moreover, results highlight opportunities for further enhancing brief interventions.

Relationship between anxiety sensitivity and post-traumatic stress symptoms in trauma-exposed adults: A meta-analysis

Given the high rate of trauma exposure among the general population, it is important to delineate the risk factors for post-traumatic stress disorder (PTSD). While historically implicated in panic disorder, anxiety sensitivity is increasingly found to play a role in PTSD. The present review investigated the size of the relationship between anxiety sensitivity and PTSD symptoms among trauma exposed adults. A systematic search on multiple electronic databases (PTSDpubs, CINAHL, MEDLINE and PsycINFO) generated a total of 1025 records, among which 52 (n = 15173) met study inclusion criteria and were included in our random effects meta-analysis. Our results indicated a medium effect size (r = .46, 95% CI =.41,.50) for the relationship between anxiety sensitivity and PTSD symptoms. There was significant between-study heterogeneity. Furthermore, sub-group analyses revealed that study design (cross-sectional vs. longitudinal) may significantly moderate the association between anxiety sensitivity and PTSD severity. No moderation effect was found for assessment of PTSD through interview versus questionnaire, interpersonal versus non-interpersonal trauma, or low versus high study quality. Such patterns of results are consistent with cognitive models of PTSD. Clinical implications, strengths and limitations of the review were discussed.

Anxiety sensitivity in terms of mental health among a racially and ethnically diverse sample of sexual minority college students

Objective: Limited work has focused on understanding the function of individual difference factors in terms of mental health among sexual minority college students. Anxiety sensitivity is one individual difference factor which has received substantial empirical attention, but its role is presently understudied among racially/ethnically diverse sexual minority college students.Participants: Participants included a racially and ethnically diverse sample of sexual minority college students (N = 217; Mage = 20.82 years; SD = 3.06).Methods: The present investigation evaluated the role of anxiety sensitivity in relation to anxious arousal, social anxiety, depression, and suicidality.Results: Results indicated that anxiety sensitivity was significantly related to increased anxious arousal, social anxiety, depression, and suicidality after adjusting for age, sex, relationship status, subjective social status, and neuroticism.Conclusions: This investigation provides the first empirical evidence that anxiety sensitivity is related to poorer mental health outcomes for racially/ethnically diverse sexual minority college students.

Association between dimensions of trauma-related psychopathology and asthma in trauma-exposed women

Introduction

Exposure to traumatic events and stressful life experiences are associated with a wide range of adverse mental and physical health outcomes. Studies have found post-traumatic stress disorder (PTSD), depression, and anxiety sensitivity occurrence to be common in addition to inflammatory diseases like asthma, especially in women. Moreover, overlapping neurobiological mechanisms have been linked to both PTSD and asthma.

Methods

In the current study, n = 508 women reported on presence of lifetime asthma diagnosis and symptoms of trauma-related psychopathology including PTSD and depression. A separate group of female participants (n = 64) reported on asthma, PTSD, depression and anxiety sensitivity, and underwent functional MRI scans during a fearful faces task, and their anterior insula responses were analyzed.

Results

Overall, PTSD and depression severity were significantly higher in those with asthma versus those without asthma. There was a positive association between anterior insula response to social threat cues and depression symptoms only among individuals without a lifetime presence of asthma.

Discussion

These findings provide continued evidence on the interactions between stress, neural mechanisms involved in interoception and salience detection, and trauma-related psychopathology.

Anxiety Sensitivity Among Trauma-Exposed Non-Hispanic Black Adults: Relations to Posttraumatic Stress

ABSTRACT

The non-Hispanic Black population experiences trauma-related disparities. One potentially important individual difference construct for posttraumatic stress is anxiety sensitivity. There is limited work on anxiety sensitivity among non-Hispanic Black persons, and no research has focused on this construct in terms of posttraumatic stress among this population. This study sought to build on this limited knowledge by exploring whether this construct was uniquely associated with more severe posttraumatic stress among this population. Participants included non-Hispanic Black trauma-exposed adults ( N = 121; Mage = 21.79 years). Results indicated that anxiety sensitivity was related to more severe overall posttraumatic stress and greater severity of each posttraumatic stress symptom cluster; all effects were evident after adjusting for the variance accounted for by age, sex, education, subjective social status, neuroticism, and number of traumatic event types experienced (lifetime). The study provides the first empirical evidence that, among a trauma-exposed non-Hispanic Black sample of adults, anxiety sensitivity is related to more severe posttraumatic stress symptoms. This intraindividual difference factor could be a focus of intervention programming for this trauma disparity population.

Transdiagnostic Processes Linking Posttraumatic Stress Disorder Symptoms to Alcohol Use Severity

Objective: The high comorbidity between posttraumatic stress disorder (PTSD) and alcohol use disorder (AUD) is well-established and complex. However, there is a need to explore transdiagnostic constructs that may underlie this association to better understand what accounts for this comorbidity and to inform treatment development. Method: Thus, the present study utilized a large, cross-sectional dataset (N = 513; Mage = 38.25 years, SD = 10.07; 49.9% female), based on national recruitment, to (1) examine whether the associations between PTSD symptom severity (PCL-5) and alcohol use severity (AUDIT) were statistically mediated by (a) anxiety sensitivity (SSASI); and (b) difficulties with emotion regulation (DERS-16); and (2) examine whether coping motives for drinking moderate this indirect effect. Sex assigned at birth was included as a covariate. Results: When examining the hypothesized mediators (SSASI and DERS-16) in separate models, there was a statistically significant indirect effect of PCL-5 on AUDIT through both SSASI and DERS. However, when both SSASI and DERS were entered into a model simultaneously, only SSASI served as a statistically significant mediator. Coping motives for drinking did not moderate the observed indirect effect. Conclusions: The current findings highlight anxiety sensitivity and emotion regulation as transdiagnostic processes that may explain, at least partially, the relationship between PTSD symptom severity and alcohol use; however, stronger evidence was evident for anxiety sensitivity. These findings may help inform the development of refined, streamlined interventions for PTSD and alcohol use that directly target these processes.

Investigating pathways from anxiety sensitivity to impairment in a treatment-seeking sample

BACKGROUND

Previous research suggests that high anxiety sensitivity (AS) - a fear of arousal-related body sensations - may have implications not only for mental health symptoms but also for functional impairment. The aim of the present study was to examine whether elevated AS is associated with functional impairment by way of heightened anxiety symptoms and resultant depressive symptoms or unhealthy coping behaviours (i.e., alcohol use, exercise avoidance, sleep problems) in a chained mediation model.

METHOD

Participants were 128 treatment-seeking individuals with high AS who qualified for an anxiety, depression, or posttraumatic stress disorder diagnosis. They completed self-report measures of AS, anxiety, depression, and unhealthy coping behaviours as part of a pre-treatment assessment battery for a larger study examining the efficacy of a cognitive behavioural intervention for AS. Data were analyzed using path analysis.

RESULTS

Results revealed a direct association between AS and functional impairment that was partially mediated through a chained indirect pathway from AS to anxiety symptoms to depression symptoms to functional impairment. Unhealthy coping behaviours did not serve as mediators.

LIMITATIONS

Results are limited by the cross-sectional nature of the data.

CONCLUSIONS

The present findings have clinical implications insofar as supporting the relevance of reducing AS and focusing on depressive symptoms when seeking to improve clients' functioning.

Anxiety sensitivity in relation to post-traumatic stress disorder symptom clusters among young adults with probable post-traumatic stress disorder

Despite the promise of past research on anxiety sensitivity (AS) and posttraumatic stress, extant work is limited, given (1) most studies consist of non-Hispanic White and middle-aged samples, (2) few have demonstrated incremental validity to general emotional traits and social determinants of health, and (3) limited work has characterized how AS relates to specific Posttraumatic Stress Disorder (PTSD) symptom clusters among those with (probable) PTSD. The current study evaluated the role of AS in relation to PTSD symptom clusters among a racially/ethnically diverse sample of young adults with probable PTSD. Participants included young adults who met the clinical cut-off for probable PTSD per the Posttraumatic Diagnostic Scale. Results indicated that AS was significantly related to overall posttraumatic stress symptom severity; the effect was evident after adjusting for a range of covariates including neuroticism and subjective social status. AS also was incrementally associated with arousal and hyperreactivity, changes in mood and cognition, and intrusion PTSD symptom clusters. In contrast to expectation, no effect for AS was evident for the avoidance PTSD symptom cluster. The current data uniquely add to the existing AS PTSD literature by showcasing distinct symptom cluster patterns among a racially/ethnically diverse sample of young adults with probable PTSD.

Single-Session Therapy by Appointment for the Treatment of Anxiety Disorders in Youth and Adults: A Systematic Review of the Literature

Purpose: This systematic review provides a summary of the available evidence of the efficacy of single-session therapy (SST) on anxiety disorders in both youth and adults. Methods: PubMed, Scopus, Medline, and Google Scholar databases were search for relevant articles, and the Cochrane Collaboration's tool for assessing the risk of bias in randomized trials was used for transparent reporting of the methodological quality of each selected study. Results: The search of electronic databases identified 18 reports based on rigorous inclusion criteria. Single-session therapy was found superior to no treatment in reducing anxiety symptoms, and similar results were observed while comparing SST to multi-treatment sessions. Discussion: The findings support the benefits of SST in enhancing cognitive, behavioral, and psychological outcomes in both youth and adults suffering from anxiety disorders across treatment conditions and approaches, SST thus appears to be a promising way of providing access to both private and public therapeutic services efficiently and cost-effectively. Conclusions: Single-session therapy is effective in treating anxiety disorders. Further research is required to quantify its cost-effectiveness and deepen the knowledge of effective treatment ingredients for both young people and the adult population suffering from diverse anxiety disorders.

Associations between Lower-Order Anxiety Sensitivity Facets and PTSD Symptomatology among Trauma-Exposed Firefighters

Firefighters are chronically exposed to potentially traumatic events, augmenting their risk of developing posttraumatic stress disorder (PTSD). The current study aimed to examine the incremental associations of lower-order dimensions of anxiety sensitivity (AS), examined concurrently, and PTSD symptom severity among a sample of trauma-exposed firefighters. We hypothesized that AS physical and cognitive concerns would be strongly associated with all PTSD symptom clusters and overall symptom severity, after controlling for theoretically relevant covariates (trauma load; years in fire service; alcohol use severity; depressive symptom severity). Participants were comprised of firefighters (N = 657) who completed an online questionnaire battery and endorsed PTSD Criterion A trauma exposure. Results revealed that the AS cognitive concerns, but not AS physical concerns, was significantly and robustly associated with overall PTSD symptom severity, intrusion symptoms, and negative alterations in cognitions and mood (∆R²'s = .028-.042; p's < .01); AS social concerns was incrementally associated with PTSD avoidance (∆R² = .03, p < .01). Implications for firefighter-informed, evidence-based interventions are discussed.

Sleep Quality Moderates the Relationship between Anxiety Sensitivity and PTSD Symptoms in Combat-exposed Veterans

Objective/Background: Posttraumatic stress disorder (PTSD) and related conditions (e.g., depression) are common in Operation Enduring Freedom, Operation Iraqi Freedom, and Operation New Dawn (OEF/OIF/OND) veterans. High anxiety sensitivity (AS), defined as fear of anxiety and anxiety-related consequences, is related to greater PTSD and depressive symptoms; however, few studies have identified possible modifiers of these associations. The current study examined the moderating role of sleep quality in the associations between AS and PTSD and depressive symptoms. Participants: Participants were 155 OEF/OIF/OND community veterans ages 21-40 (12.3% women). Methods: Participants completed a semi-structured clinical interview for DSM-IV PTSD symptoms (Clinician Administered PTSD Scale; CAPS) and self-report measures of anxiety sensitivity (Anxiety Sensitivity Index), sleep quality (Pittsburgh Sleep Quality Index global score; PSQI), and depressive symptoms (Beck Depression Inventory-II; BDI-II). Results: Results of hierarchical linear regression models indicated that the main effects of AS and global PSQI score were significantly associated with greater PTSD and depressive symptoms (both with sleep items removed), above and beyond the covariates of trauma load and military rank. Sleep quality moderated the relationship between AS and PTSD symptoms (but not depressive symptoms), such that greater AS was associated with greater PTSD symptoms for individuals with good sleep quality, but not poor sleep quality. Conclusions: Sleep quality and AS account for unique variance in PTSD and depressive symptoms in combat-exposed veterans. AS may be less relevant to understanding risk for PTSD among combat-exposed veterans experiencing poor sleep quality.

The Role of Anxiety Sensitivity in the Relation Between Pain Intensity with Substance Use and Anxiety and Depressive Symptoms Among Smokers with Chronic Pain

BACKGROUND

The additive effect of experiencing chronic pain in the context of nicotine addiction places smokers with chronic pain at elevated risk for experiencing physical and mental health problems. Isolating factors that explain linkages between pain and health-related outcomes among smokers with chronic pain is an important next step. Therefore, the current study examined the explanatory role of anxiety sensitivity in relations between pain intensity and current opioid misuse, severity of opioid dependence, tobacco-related problems, and anxiety/depressive symptoms.

METHOD

Participants were 187 (M_age = 39.02, SD = 9.94, 74.9% female) daily smokers with chronic pain who completed a battery of self-report measures on pain experience, anxiety sensitivity, tobacco and opioid use, and anxiety/depression symptoms. Indirect effect analyses were conducted to examine anxiety sensitivity as a mediator of the relations between pain intensity and health-related outcomes.

RESULTS

A significant indirect effect emerged for pain intensity, through anxiety sensitivity, on opioid misuse (ab = 0.83, SE = 0.24, 95% CI [0.39, 1.34], CSE = 0.17), severity of opioid dependence (ab = 0.17, SE = 0.05, 95% CI [0.08, 0.26], CSE = 0.16), tobacco use problems (ab = 0.16, SE = 0.06, 95% CI [0.07, 0.28], CSE = 0.11), and anxiety/depressive symptoms (ab = 0.20, SE = 0.06, 95% CI [0.10, 0.31], CSE = 0.19).

CONCLUSION

The current investigation highlights the potential importance of anxiety sensitivity in terms of the experience of pain with severity of substance use and anxiety/depressive symptoms among smokers with chronic pain.

Anxiety sensitivity and opioid misuse and dependence among trauma-exposed adults with chronic pain

It is unclear if anxiety sensitivity may serve as mechanism underlying the relation between posttraumatic stress symptom severity and opioid misuse and dependence among trauma-exposed persons with chronic pain. Therefore, the current study evaluated the explanatory role of anxiety sensitivity in the relations between posttraumatic stress symptom severity and opioid misuse and dependence. Participants included 294 trauma-exposed adults with chronic pain (71.4% female, M_age = 37.79 years, SD = 10.85, M_{pain rating} = 7.32/10) that reported current moderate to severe chronic pain and prescription opioid use. Participants were recruited via an online national survey in the United States of America. There were statistically significant indirect effects of posttraumatic stress symptom severity via anxiety sensitivity in relation to opioid misuse and dependence. The indirect effects of the reverse models for opioid misuse and dependence also were significant and suggest the potential for bi-directional relations; however, the magnitude of the effect was smaller in the tests of specificity than in the original models. The present findings provide initial empirical evidence that greater posttraumatic stress symptom severity is related to anxiety sensitivity, which in turn, is associated with increased opioid misuse and dependence among trauma-exposed individuals with chronic pain.

Mindfulness and Interoceptive Exposure Therapy for Anxiety Sensitivity in Atrial Fibrillation: A Pilot Study

Atrial fibrillation is the most common cardiac arrhythmia and symptoms overlap with physiological sensations of anxiety. Patients with atrial fibrillation can demonstrate anxiety sensitivity even in the absence of actual atrial fibrillation symptoms. Interoceptive exposure is effective in treating anxiety sensitivity, and recently, mindfulness has been proposed as an enhancement strategy to facilitating inhibitory learning in exposure therapy. This pragmatic study piloted a brief mindfulness and interoceptive exposure treatment for anxiety sensitivity in atrial fibrillation. Eight participants with atrial fibrillation and elevated anxiety sensitivity from a hospital cardiology department participated in the treatment. Anxiety sensitivity significantly decreased during the course of the intervention. These initial findings show proof of concept for this brief intervention in a cardiac-specific behavioral medicine setting.

The effects of exercise on transdiagnostic treatment targets: A meta-analytic review

BACKGROUND

The present study meta-analytically reviewed the effects of exercise on four transdiagnostic treatment targets: anxiety sensitivity (AS), distress tolerance (DT), stress reactivity (SR), and general self-efficacy (GSE).

METHODS

We conducted systematic searches of peer-reviewed studies in bibliographical databases (Cochrane Library, psychINFO, PubMed) before April 1, 2018. Only randomized controlled trials (RCT) evaluating the effect of exercise on AS, DT, SR, or GSE using at least one validated outcome instrument in a sample of adolescents (≥13 years old) or adults were selected. We employed a meta-analysis of effects using random-effects pooling modeling for each treatment target.

RESULTS

The systematic search yielded 28 RCTs meeting eligibility criteria. Exercise interventions had a large effect on reducing AS (six studies, Hedges's g = 0.72, p = .001), a medium effect on increasing GSE (eight studies, Hedges's g = 0.59, p < .001), and a small effect on reducing SR (ten studies, Hedges's g = 0.32, p < .001). Evidence from four studies suggested that exercise interventions had a small but non-significant effect on increasing DT (Hedges's g = 0.21, p = .26).

CONCLUSIONS

This meta-analysis provides preliminary evidence exercise can engage certain transdiagnostic targets. Further research is required to optimize exercise intervention parameters to achieve the strongest effects on these important mechanistic variables.

Brief behavioral interventions at free medical fairs

Free medical fairs have emerged to compensate for the lack of access to affordable health care in rural areas of the United States. Mental health services are offered less frequently than other medical services, despite a documented need, perhaps due to a belief that mental health interventions could not be effective in a single session. We examined the types of problems presented at three rural medical fairs, and whether single session mental health interventions affected participants' health confidence, distress, or progress toward health-related goals. Problems presented included mental health, legal, financial, tobacco cessation, and relationship problems. Findings indicated that, on average, participants gained health confidence and reduced distress and found the service very helpful. The majority of those reached for phone follow-up reported progress on one or more health goals. Goals that involved manageable steps within the participants' own control, such as gratitude practices or progressive muscle relaxation, were the most likely to be completed. Implementation lessons included the importance of learning about the fairs' cultures, advertising the services, location of services, being proactive in connecting with patients, and preparing resources for community referrals. Overall, findings suggest that mental health interventions can have a positive impact on some people at free medical fairs. Given that tens of thousands of people attend each year, the fairs offer a fruitful opportunity to reach some of our most underserved citizens.

Refinement of anxiety sensitivity measurement: The Short Scale Anxiety Sensitivity Index (SSASI)

Anxiety sensitivity, defined as the fear of anxiety and arousal-related sensations, has been among the most influential cognitive-based transdiagnostic risk and maintenance factors in the study and treatment of emotional and related disorders. The currently available anxiety sensitivity measures are limited by their length. Specifically, the length of these instruments discourages the adoption of routine anxiety sensitivity assessment in clinical or medical settings (e.g., primary care). The goals of this study were to develop and assess the validity and reliability of a short version of the Anxiety Sensitivity Index-3 (ASI-3; Taylor et al., 2007), entitled the Short Scale Anxiety Sensitivity Index (SSASI), using three independent clinical samples. Results indicated that the abbreviated five-item version of the SSASI had good internal consistency and a robust association with the ASI-3. Further, across the samples, there was evidence of unidimensionality and excellent convergent and discriminant validity. There also was evidence of partial measurement invariance across sex and full measurement invariance across time. Overall, the five-item scale offers a single score that can be employed to measure anxiety sensitivity. Use of the SSASI may facilitate screening efforts and symptom tracking for anxiety sensitivity, particularly within clinical settings where practical demands necessitate the use of brief assessment instruments.

Anxiety sensitivity in the association between posttraumatic stress and substance use disorders: A systematic review

Posttraumatic stress disorder (PTSD) and substance use disorders (SUD) are complex psychiatric conditions that commonly co-occur. No evidence-based, "gold standard" treatments for PTSD/SUD comorbidity are currently available. Thus, it is imperative to better understand cognitive-affective mechanisms, targetable via cognitive-behavioral intervention (i.e., malleable), that may be related to both disorders in order to improve the theory and treatment of PTSD/SUD. Anxiety sensitivity is a malleable cognitive-affective factor with relevance to both PTSD and SUD. This systematic review focused on the published literature on anxiety sensitivity and trauma/PTSD and substance use/SUD from 1966 - May 1, 2018, and includes a total of 35 manuscripts. The state of the literature, limitations, and future research directions are discussed.

The role of anxiety sensitivity in reactivity to trauma cues in treatment-seeking adults with substance use disorders

BACKGROUND

Exposure to traumatic events and posttraumatic stress disorder (PTSD) are common among individuals with substance use disorders (SUDs). Although the presence of trauma exposure and/or PTSD among those with SUDs is associated with a range of negative outcomes, much remains to be understood about the factors contributing to these outcomes. Anxiety sensitivity (the tendency to respond fearfully to the signs and symptoms of anxiety) has been linked to greater PTSD symptoms and the use of substances to cope with PTSD symptoms, and is a promising factor for understanding the negative outcomes associated with co-occurring PTSD and SUDs.

METHODS

This study examined the association between anxiety sensitivity and trauma cue reactivity among 194 trauma-exposed patients with SUDs (27.3% met criteria for current PTSD). Participants completed ratings of negative affect and substance cravings prior to and after exposure to a personally-relevant trauma cue.

RESULTS

Results indicated that anxiety sensitivity was associated with greater emotional reactivity (but not craving reactivity) to the trauma cue; neither PTSD symptom severity nor PTSD diagnosis moderated these associations. PTSD symptom severity was associated with greater emotional and craving reactivity to the trauma cue.

CONCLUSIONS

Results highlight the potential utility of targeting anxiety sensitivity in treatments for trauma-exposed patients with SUDs with and without PTSD.

Randomized Clinical Trial Investigating the Effects of an Anxiety Sensitivity Intervention on Posttraumatic Stress Symptoms: A Replication and Extension

A growing body of research suggests the importance of anxiety sensitivity (AS) in the development and maintenance of posttraumatic stress symptoms (PTSS). Specifically, AS cognitive concerns (fears of cognitive dyscontrol) may be particularly relevant for those with elevated PTSS. Preliminary research has suggested that interventions targeting AS may be beneficial in decreasing PTSS, but to date there has been no randomized controlled trial testing the direct and indirect effects of an AS cognitive concerns intervention among a clinical sample of trauma-exposed individuals. The current study tested these effects among a sample 63 trauma-exposed participants who were randomized to either an AS cognitive concerns intervention or a repeated contact control. Results indicated a direct effect of the intervention on PTSS 1 month postintervention, and that this effect was mediated by changes in AS, specifically AS cognitive concerns, during the intervention period. Effect sizes were in the small-to-medium range (variance accounted for ranged from .05 to .15; odds ratio for diagnostic change = .06). These findings provide further evidence that targeting AS may be beneficial in the treatment of PTSS, and expansion upon this area of research by demonstrating these effects may be specific to AS cognitive concerns and can be achieved within a mixed clinical sample.

Transdiagnostic mechanisms of change and cognitive-behavioral treatments for PTSD

This paper reviews the current status of transdiagnostic mechanisms of change targeted in cognitive-behavioral interventions, with a focus on mechanisms that are also relevant to emotional disorders that frequently co-occur with PTSD. First, an overview of the rationale for and key features of identifying mechanisms of change is presented, with a discussion of why it is crucial to examine mechanisms that are relevant across diagnostic boundaries. A review of the current evidence for five promising transdiagnostic mechanisms (hope, neuroticism, emotion regulation, cognitive reappraisal, and anxiety sensitivity) is then provided. Finally, the implications of the increasing evidence of transdiagnostic mechanisms of change are discussed in relation to recently developed transdiagnostic treatment protocols that provide an alternative treatment approach for PTSD.

Origins and outlook of interoceptive exposure

BACKGROUND AND OBJECTIVES

Interoceptive exposure (IE) is a behavioral intervention that reduces anxiety sensitivity and distress associated with somatic sensations. In this discussion, we describe the history, current applications and additional clinical potential of IE.

METHOD

We review the origins of IE and its historical application to panic disorder, as well as the accumulating evidence for transdiagnostic application to other disorders including post-traumatic stress disorder, social anxiety disorder, specific phobias and physical disorders. Then, we discuss ways in which IE could contribute to the treatment of additional disorders.

RESULTS

IE is well-established in the treatment of panic disorder and increasingly used to target anxiety-provoking physical sensations in other disorders. Research and clinical evidence suggests that anxiety sensitivity is present across a range of disorders, and may actually be one variation on a broader phenomenon of interoceptive sensitivity, or anxiety focused on physical sensations that have been conditioned to unpleasant emotional states. Moreover, somatic symptoms are central to the experience of most emotions and may contribute to avoidant coping, a maintenance factor for disorders of emotion. IE has potential as a transdiagnostic intervention targeting interoceptive sensitivity in disorders such as depression and eating disorders. Nevertheless, IE is underutilized by clinicians in practice. Recent research in inhibitory learning and extinction suggests strategies for maximizing the effectiveness of IE.

LIMITATIONS

This review is not exhaustive in nature, and systematic research on transdiagnostic applications of IE remains scarce.

CONCLUSIONS

IE is a potentially powerful yet understudied transdiagnostic intervention.

Predictors and Outcomes of Growth Mixture Modeled Trajectories Across an Exposure-Based PTSD Intervention With Veterans

OBJECTIVES

Exposure-based psychotherapies for posttraumatic stress disorder (PTSD) are effective for many, but not all patients. It is important to determine for whom these treatments work and to examine predictors of success.

METHOD

An 8-week modified prolonged exposure (PE) treatment, including components of behavioral activation and reducing the number of imaginal exposure sessions, was administered to a sample of 231 Veterans (mean age = 45.7 years, standard deviation = 14.89). Growth mixture modeling was used to model PTSD symptom trajectories across the 8-week intervention and a postintervention appointment. Further, baseline demographics, social support, clinician-rated PTSD symptoms, anxiety, and depression were examined as predictors of trajectories.

RESULTS

Three classes emerged, labeled responders (n = 35), nonresponders (n = 190), and immediate responders (n = 6). The only significant baseline difference between responders and nonresponders was higher anxiety symptoms in the nonresponders. At follow-up time points, there were higher levels of clinician-rated PTSD, anxiety, and depression symptoms and lower social support in the nonresponders compared to the responders.

CONCLUSION

Findings suggest that modifying standard PE treatments by reducing imaginal exposure sessions while adding behavioral activation may not be advisable for most Veterans with PTSD.

Anxiety Sensitivity Prospectively Predicts Posttraumatic Stress Symptoms Following a Campus Shooting

Anxiety sensitivity (AS), the feared consequences of anxious arousal, is known to be related to posttraumatic stress symptoms (PTSS) concurrently and longitudinally. However, no studies have demonstrated whether AS prior to a Criterion A traumatic event predicts later PTSS. The present study evaluated whether preshooting AS predicted PTSS following a campus shooting, as well as whether preshooting AS interacted with shooting exposure to predict PTSS. Participants comprised undergraduates (N=71) who completed a self-report battery upon enrolling in Introductory Psychology. After a campus shooting later in the semester, they were invited to complete measures of PTSS and level of exposure to the shooting. Preshooting levels of AS significantly predicted PTSS after the shooting. This effect was qualified by a significant AS by shooting exposure interaction, such that those with high AS who were exposed to the shooting reported the greatest levels of PTSS. Though all three of the preshooting physical, cognitive, and social AS subfactors demonstrated main effects significantly predicting postshooting PTSS, only AS physical concerns significantly interacted with shooting exposure. The implications of this study concerning AS as a causal risk factor for PTSD are discussed.

Post-traumatic stress disorder symptoms, underlying affective vulnerabilities, and smoking for affect regulation

BACKGROUND AND OBJECTIVES

Post-traumatic stress disorder (PTSD) is overrepresented among cigarette smokers. It has been hypothesized that those with PTSD smoke to alleviate negative affect and counteract deficient positive affect commonly associated with the disorder; however, limited research has examined associations between PTSD symptoms, smoking motives, and affective vulnerability factors. In the current study, we examined (1) whether PTSD symptoms were associated with positive reinforcement and negative reinforcement smoking motives; and (2) whether two affective vulnerability factors implicated in PTSD-anxiety sensitivity and anhedonia-mediated relationships between PTSD symptoms and smoking motives.

METHODS

Data were drawn from a community sample of non-treatment-seeking smokers recruited without regard for trauma history (N = 342; 10+ cig/day). We used the Posttraumatic Stress Disorder Checklist-Civilian Version (PCL-C) to assess overall PTSD symptom severity as well as individual PTSD subfactors.

RESULTS

Overall, PTSD symptom severity was significantly associated with negative reinforcement, but not positive reinforcement, smoking motives. Variation in anxiety sensitivity significantly mediated the relation between PTSD symptom severity and negative reinforcement smoking motives, whereas anhedonia did not. Regarding PTSD subfactors, emotional numbing was the only PTSD subfactor associated with smoking rate, while re-experiencing symptoms were uniquely associated with both positive reinforcement and negative reinforcement smoking motives.

CONCLUSIONS AND SCIENTIFIC SIGNIFICANCE

Findings suggest that anxiety sensitivity may be an important feature associated with PTSD that enhances motivation to smoke for negative reinforcement purposes. Smoking cessation interventions that alleviate anxiety sensitivity and enhance coping with negative affect may be useful for smokers with elevated PTSD symptoms.

Commitment language and homework completion in a behavioral employment program for gang-affiliated youth

Research with substance-abusing samples suggests that eliciting commitment language during treatment may improve motivation to change, increase treatment engagement, and promote positive treatment outcomes. However, the relationship between in-session client language and treatment success is not well-understood for youth offender populations. This study evaluated the relationship between commitment language, treatment engagement (i.e., homework completion), and weekly employment outcomes for six gang-affiliated juvenile offenders participating in an employment counseling intervention. Weekly counseling sessions were audio-recorded, transcribed, and coded for commitment language strength. Multilevel models were fit to the data to examine the relationship between commitment language and counseling homework or employment outcomes within participants over time. Commitment language strength predicted subsequent homework completion but not weekly employment. These findings imply that gang-affiliated delinquent youth who express motivation to change during employment counseling will be more likely to comply with counselor-initiated homework. Further research on counselor techniques for promoting commitment language among juvenile gang offenders is needed.

Anxiety, depression, and cigarette smoking: a transdiagnostic vulnerability framework to understanding emotion-smoking comorbidity

Research into the comorbidity between emotional psychopathology and cigarette smoking has often focused upon anxiety and depression's manifest symptoms and syndromes, with limited theoretical and clinical advancement. This article presents a novel framework to understanding emotion-smoking comorbidity. We propose that transdiagnostic emotional vulnerabilities-core biobehavioral traits reflecting maladaptive responses to emotional states that underpin multiple types of emotional psychopathology-link various anxiety and depressive psychopathologies to smoking. This framework is applied in a review and synthesis of the empirical literature on 3 transdiagnostic emotional vulnerabilities implicated in smoking: (a) anhedonia (Anh; diminished pleasure/interest in response to rewards), (b) anxiety sensitivity (AS; fear of anxiety-related sensations), and (c) distress tolerance (DT; ability to withstand distressing states). We conclude that Anh, AS, and DT collectively (a) underpin multiple emotional psychopathologies, (b) amplify smoking's anticipated and actual affect-enhancing properties and other mechanisms underlying smoking, (c) promote progression across the smoking trajectory (i.e., initiation, escalation/progression, maintenance, cessation/relapse), and (d) are promising targets for smoking intervention. After existing gaps are identified, an integrative model of transdiagnostic processes linking emotional psychopathology to smoking is proposed. The model's key premise is that Anh amplifies smoking's anticipated and actual pleasure-enhancing effects, AS amplifies smoking's anxiolytic effects, and poor DT amplifies smoking's distress terminating effects. Collectively, these processes augment the reinforcing properties of smoking for individuals with emotional psychopathology to heighten risk of smoking initiation, progression, maintenance, cessation avoidance, and relapse. We conclude by drawing clinical and scientific implications from this framework that may generalize to other comorbidities.

Trait Emotional Intelligence, Anxiety Sensitivity, and Experiential Avoidance in Stress Reactivity and Their Improvement Through Psychological Methods

Stress pervades daily society, often with deleterious consequences for those prone to react intensely to it. Intervention techniques to attenuate stress reactivity are thus paramount. With that goal in mind, researchers have sought to identify and alter malleable psychological dispositional variables that influence stress reactivity. Trait emotional intelligence (TEI), anxiety sensitivity (AS), and experiential avoidance (EA) are increasingly receiving attention in these research efforts. The self-reported emotional component of stress reactivity has been emphasized in investigations and is our focus. Specifically, this paper overviews the role of TEI, AS, and EA in self-reported stress responses. We also discuss empirically supported psychological methods to adjust suboptimal levels of these variables in normal populations. Both psycho-educational (information, skills) and mindfulness-based interventions (specific mindfulness therapies or components) are covered. Findings include that (1) TEI, AS, and EA are each correlated with the emotional component of stress reactivity to both naturalistic and lab-based stressors; (2) preliminary support currently exists for psycho-educational intervention of TEI and AS but is lacking for EA; (3) adequate evidence supports mindfulness-based interventions to target EA, with very limited but encouraging findings suggesting mindfulness methods improve TEI and AS; and (4) although more research is needed, stress management approaches based on mindfulness may well target all three of these psychological variables and thus appear particularly promising. Encouragingly, some methods to modify dispositional variables (e.g., a mindfulness-based format of guided self-help) are easily disseminated and potentially applicable to the general public.

Reduction of cognitive concerns of anxiety sensitivity is uniquely associated with reduction of PTSD and depressive symptoms: a comparison of civilians and veterans

PTSD and comorbid depression are common among civilians and veterans, resulting in substantial impairment. Anxiety sensitivity (AS) may be a common malleable vulnerability factor for PTSD and depression. The AS cognitive concerns subscale is most strongly related to symptoms of PTSD and depression, and thus, may be an efficient route to reduce these symptoms. The current study evaluated a brief computerized intervention targeting AS cognitive concerns. Specifically, we evaluated whether reduction in AS cognitive concerns was associated with reduction in symptoms of PTSD and depression. Also, we evaluated whether there was a significant difference between civilians and veterans in response to the intervention. The single session intervention utilized psychoeducation and interoceptive exposure to target AS cognitive concerns. This intervention was compared to a health information condition among a sex-matched sample of civilians and veterans with elevated AS cognitive concerns (N = 56). Reduction in AS cognitive concerns over one month was uniquely associated with reduction in PTSD and depressive symptoms in the same time frame. There were no significant differences between civilians and veterans in response to the intervention suggesting the intervention has efficacy for both groups. Treatment implications are discussed.

The role of anxiety sensitivity in the experience of menstrual-related symptoms reported via daily diary

The current study examined the interactive effects of Anxiety Sensitivity (AS) and menstrual cycle phase in the experience of menstrual-related symptoms. Participants were 55 community women who completed prospective tracking of menstrual-related symptoms across at least one full menstrual cycle using the Daily Record of Severity of Problems (DRSP) and completed the Menstrual Distress Questionnaire (MDQ) once in their premenstrual and follicular cycle phases. Results revealed that women with higher levels of AS reported greater menstrual-related symptoms, regardless of cycle phase, as compared to women with lower levels of AS. These findings suggest that AS may be an important psychological factor involved in the experience of psychological and somatic symptoms across the menstrual cycle. Results are consistent with previous literature documenting the role of AS in menstrual-related symptoms as well as in other physical health conditions.

Longitudinal course of anxiety sensitivity and PTSD symptoms in cognitive-behavioral therapies for PTSD

Anxiety sensitivity (AS) has been conceptualized as trait-like vulnerability and maintenance factor for PTSD. Although recent literature has demonstrated its malleability during treatment, few have examined its influence on and effect from PTSD treatment. Using multilevel regression analyses we examined: (a) changes in AS during treatment and (b) whether pre-treatment AS predicted PTSD treatment response, in sample of female victims of interpersonal trauma receiving one of three treatments (cognitive processing therapy, cognitive processing therapy-cognitive, and written accounts). Participants exhibited reductions in total ASI scores from pre- to post-treatment. Growth curve modeling revealed slightly different trajectories of PTSD symptoms as a function of pre-treatment AS, and overall decreases in PTSD symptoms during treatment were not associated with pretreatment AS. Pretreatment AS dimensions impacted PTSD total scores and symptoms clusters differentially. Clinical and theoretical implications for these results are discussed.

Factor mixture model of anxiety sensitivity and anxiety psychopathology vulnerability

BACKGROUND

The purpose of the present study was to shed light on the latent structure and nature of individual differences in anxiety sensitivity (AS) and related risk for psychopathology.

METHODS

The present study evaluated the latent structure of AS using factor mixture modeling (FMM; Lubke and Muthén, 2005) and tested the relations between the observed FMM-based model of AS and psychopathology in a large, diverse adult clinical research sample (N=481; 57.6% women; M(SD)(age)=36.6(15.0) years).

RESULTS

Findings showed that a two-class three-factor partially invariant model of AS demonstrated significantly better fit than a one-class dimensional model and more complex multi-class models. As predicted, risk conferred by AS taxonicity was specific to anxiety psychopathology, and not to other forms of psychopathology.

LIMITATIONS

The sample was not epidemiologic, self-report and psychiatric interview data were used to index AS and psychopathology, and a cross-sectional design limited inference regarding the directionality of observed relations between AS and anxiety psychopathology.

CONCLUSIONS

Findings are discussed with respect to the nature of AS and related anxiety psychopathology vulnerability specifically, as well as the implications of factor mixture modeling for advancing taxonomy of vulnerability and psychopathology more broadly.

Innovations in the treatment of anxiety psychopathology: introduction

Behavioral and cognitive interventions have an established history of efficacy for the treatment of anxiety disorders. The majority of patients receiving these empirically supported interventions for anxiety exhibit improvement and these changes tend to be maintained following treatment. Moreover, emerging data suggest that cognitive-behavioral protocols can be effectively transferred to real-world settings such as primary care practices. On the other hand, historical reviews indicate that the relative efficacy of treatments for anxiety have not substantially improved over time. A further concern is that there are relatively few innovations in the treatment of anxiety during the past 20years. Thus, we appear to have reached somewhat of a plateau with regard to treatment response, which would suggest a need to consider novel methods and approaches. This special series will describe new and innovative approaches to the treatment of anxiety psychopathology.
