A prospective test of anxiety sensitivity as a moderator of the relation between gender and posttraumatic symptom maintenance among high anxiety sensitive young adults

The Neurophysiology of Interoceptive Disruptions in Trauma-Exposed Populations

In the aftermath of psychological trauma, many individuals experience perturbations in interoception, a term that broadly references the ability to accurately detect body signals and integrate these signals with emotional states. These interoceptive disruptions can manifest in different ways, including blunting or amplification of sensitivity to internal physiological signals. In this chapter we review extant neurophysiological research on interoception in trauma-exposed populations, with a particular focus on the effects of chronic interpersonal trauma, such as childhood maltreatment and racial discrimination. We explore research that used different types of interoceptive assays, from self-report measures to electrophysiological and neuroimaging tools to characterize the disruptions in pain perception, interoceptive acuity, and physiological responses that may arise after a traumatic event. Finally, we discuss interventions that are designed to target interoceptive mechanisms, from exposure-based therapies to mindfulness-based practices, as well as future directions in trauma interoception research.

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.

Impact of earthquake exposure, family adversity and peer problems on anxiety-related emotional disorders in adolescent survivors three years after the Ya'an earthquake

BACKGROUND

Traumatic experiences often give rise to an increased risk of anxiety problems in adolescents. This study investigated the anxiety prevalence in adolescent earthquake survivors and the effect of secondary stressors such as bullying, poverty, or being "left behind" by parents working in the cities.

METHODS

This cross-sectional study was conducted three years after the 2013 Ya'an (China) earthquake on 6,132 adolescents aged 9 to 18 years from 11 public schools in three severely earthquake affected counties. The participants completed self-report questionnaires that assessed anxiety, earthquake exposure, poverty level, left-behind duration and bullying.

RESULTS

Separation anxiety (38.7%) and panic symptoms (32.2%) were found to be the primary contributors to anxiety in this adolescent sample. The regression and structural equation modeling indicated that adolescents who had suffered from high earthquake exposure, peer bullying, being left-behind, or poverty were more likely to report problems in all anxiety subcategories, with females reporting more anxiety symptoms than males. The likelihood of all anxiety disorders except separation anxiety was found to increase with age.

CONCLUSIONS

This study highlighted the need for post-disaster interventions aimed at minimizing post-earthquake adversity such as peer bullying and specialized psychological services that target subgroups that might be more susceptible to anxiety-related emotional problems. The results could be used to identify possible markers for anxiety problems in children who had not experienced any major traumas.

Reductions in anxiety sensitivity cognitive concerns prospectively mitigate trauma symptom development

Identifying a malleable pre-trauma risk marker for posttraumatic stress is crucial to preventing symptom development among at-risk individuals. One such candidate is anxiety sensitivity cognitive concerns (ASCC), which represents the fear of psychological incapacitation due to anxious arousal. While the extant literature suggests that applying ASCC interventions prior to trauma exposure should mitigate development of posttraumatic stress symptoms (PTSS), this has not been formally tested. We examined whether individuals randomized to receive a Cognitive Anxiety Sensitivity Treatment (CAST; n = 44) prior to a trauma film paradigm would report lower film-specific PTSS after one week compared to individuals randomized to a physical health education training control condition (n = 47). Results revealed that post-intervention ASCC and week-one PTSS were both lower among the CAST condition, and reductions in ASCC mediated the relationship between intervention condition and follow-up PTSS. The current study demonstrated that reducing ASCC prior to an analog trauma can mitigate the development of PTSS. This is critical for establishing ASCC as a causal risk factor for PTSS and encourages the use of ASCC interventions in samples at-risk for trauma exposure.

The Indirect Effect of Child Maltreatment Severity on Adult PTSD Symptoms through Anxiety Sensitivity

Although the rate of posttraumatic stress disorder (PTSD) among survivors of child maltreatment is high, individuals differ in symptom severity and many do not experience clinically significant levels of psychopathology. The present study tested the indirect effects of child maltreatment severity on adult PTSD, suicidal ideations, and alcohol dependence via anxiety sensitivity. A sample of 336 participants (mean age of 22.81 years, SD = 8.93; 70.2% female) completed an online survey of child abuse and neglect, anxiety sensitivity, PTSD symptom severity, suicidal ideation severity, and alcohol dependence severity. The results revealed significant indirect effects of child maltreatment on PTSD symptom severity through cognitive and social concerns, but not physical concerns. No direct or indirect effects were demonstrated for suicidal ideations or alcohol dependence severity. These findings elucidate mechanisms in the robust relationship between child maltreatment and adult PTSD symptoms and can potentially inform future research on mechanisms of change in psychotherapy.

The Moderating Effect of Smoking Status on the Relation between Anxiety Sensitivity, Sexual Compulsivity, and Suicidality among People with HIV/AIDS

PURPOSE

The present study examined the moderating effect of cigarette smoking status on the relation between anxiety sensitivity (fear of the expected negative consequences of anxiety and bodily sensations) and hazardous alcohol consumption, sexual compulsivity, and suicidality.

METHOD

A series of multiple hierarchical regressions were used to test the proposed hypothesis among a sample of 94 persons living with HIV/AIDS in the USA (64.5 % male, M _age = 48.3, SD = 7.5). Fifty-seven percent of the participants (n = 54) reported past-month smoking.

RESULTS

The results indicated that those who reported smoking and had higher anxiety sensitivity demonstrated the highest rates of hazardous alcohol use, sexual compulsivity, and suicidality. Simple slope analyses indicated that anxiety sensitivity was associated with higher rates of hazardous alcohol use, sexual compulsivity, and suicidality among individuals who reported past-month smoking, but not among individuals who did not smoke.

CONCLUSION

The present results suggest that smoking status moderates the relation between anxiety sensitivity and hazardous alcohol use, sexual compulsivity, and suicidality among persons living with HIV/AIDS. These data add to a growing literature, suggesting that smoking has a negative impact among persons living with HIV/AIDS, which extends beyond physical health problems to a variety of clinically significant behavioral health sequelae.

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.

A new perspective on PTSD symptoms after traumatic vs stressful life events and the role of gender

Background: There is an ongoing debate about the validity of the A1 criterion of PTSD. Whereas the DSM-5 has opted for a more stringent A1 criterion, the ICD-11 will leave it out as a key criterion. Objective: Here we investigated whether formal DSM-IV-TR traumatic (A1) and stressful (non-A1) events differ with regard to PTSD symptom profiles, and whether there is a gender difference in this respect. Method: This was examined in a large, mostly clinical sample from the Netherlands Study of Depression and Anxiety (n = 1433). Participants described their most bothersome (index) event and were assigned to either an A1 or non-A1 event group according to this index event. Results: Remarkably, in men PTSD symptoms were even more severe after non-A1 than A1 events, whereas in women symptoms were equally severe after non-A1 and A1 events. Moreover, while women showed significantly higher PTSD symptoms after A1 events than men (29.9 versus 15.4% met PTSD criteria), there was no gender difference after non-A1 events (women: 28.2%; men: 31.3%). Furthermore, anxiety and perceived impact were higher in women than men, which was associated with PTSD symptom severity. Conclusion: In sum, while women showed similar levels of PTSD symptoms after both event types, men reported even higher levels of PTSD symptoms after non-A1 than A1 events. These findings shed a new light on the role of gender in PTSD symptomatology and the clinical usefulness of the A1 criterion.

The utility of the bifactor model in understanding unique components of anxiety sensitivity in a South Korean sample

The present study was the first to examine the applicability of the bifactor structure underlying the Anxiety Sensitivity Index-3 (ASI-3) in an East Asian (South Korean) sample and to determine which factors in the bifactor model were significantly associated with anxiety, depression, and negative affect. Using a sample of 289 South Korean university students, we compared (a) the original 3-factor AS model, (b) a 3-group bifactor AS model, and (c) a 2-group bifactor AS model (with only the physical and social concern group factors present). Results revealed that the 2-group bifactor AS model fit the ASI-3 data the best. Relatedly, although all ASI-3 items loaded on the general AS factor, the Cognitive Concern group factor was not defined in the bifactor model and may therefore need to be omitted in order to accurately model AS when conducting factor analysis and structural equation modeling (SEM) in cross cultural contexts. SEM results also revealed that the general AS factor was the only factor from the 2-group bifactor model that significantly predicted anxiety, depression, and negative affect. Implications and importance of this new bifactor structure of Anxiety Sensitivity in East Asian samples are discussed.

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.

Factor Structure and Psychometric Properties of the Anxiety Sensitivity Index-3 in an Italian Community Sample

Anxiety Sensitivity (AS) is defined as the fear of anxiety and of arousal-related bodily sensations, arising from erroneous beliefs that these sensations will have adverse consequences. AS plays a key role both in the onset and in the maintenance of several disorders, particularly anxiety disorders. To date, only two studies on American samples have examined the bifactor structure of the Anxiety Sensitivity Index-3 (ASI-3); therefore, findings on different cultures are needed. The main purpose of the present study was to assess the factor structure and psychometric properties of the ASI-3 in an Italian community sample. Participants were recruited from the general population (N = 1507). The results of a series of confirmatory factor analyses indicated that the bifactor structure fitted the data better than the most commonly accepted structure for the measure and that it was invariant across gender. Moreover, the current study provided evidence regarding the ASI-3’s reliability and its convergent and divergent validity. Lastly, results pertaining incremental validity of the ASI-3 Physical and Cognitive Concerns subscales above and beyond the total showed that the former was not associated with a measure of physiological anxiety, whereas the latter was weakly associated with a measure of worry. Findings suggest that the ASI-3 is comprised of a dominant general factor and three specific independent factors; given the dominance of the general factor, the use of the ASI-3 total score as a measure of the general fear of anxiety is recommended in both clinical and research settings.

Further Investigation of the Association between Anxiety Sensitivity and Posttraumatic Stress Disorder: Examining the Influence of Emotional Avoidance

Anxiety sensitivity (AS) and the tendency to avoid emotions have both been identified as vulnerability factors for the development and maintenance of posttraumatic stress disorder (PTSD). Furthermore, both cross-sectional and prospective research have provided evidence that emotional avoidance and AS interact to predict anxiety symptoms, such that AS may only be associated with anxiety-related pathology among those who exhibit a tendency to avoid their emotions. The purpose of the present study was to determine if this moderator model extends to PTSD within a sample of substance dependent patients. Specifically, this study examined if AS is associated with PTSD only among individuals with high (vs. low) levels of negative emotional avoidance. As predicted, results of a logistic regression analysis revealed a significant interaction between negative emotional avoidance and AS in predicting PTSD status. Follow-up analyses revealed a significant positive association between AS and PTSD status for participants high in negative emotional avoidance; however, AS was not associated with PTSD for those low in negative emotional avoidance. This finding remained even when relevant covariates were included in the model. Results confirm hypotheses and are consistent with the extant anxiety-risk literature.

The Relationship between Anxiety Sensitivity and Posttraumatic Stress Disorder: What is the Impact of Nicotine Withdrawal?

OBJECTIVES

Anxiety sensitivity (AS) is related to the development and maintenance of posttraumatic stress disorder (PTSD) among cigarette smokers, and is also implicated in the amplification of acute nicotine withdrawal symptoms. The present study sought to examine the role of nicotine withdrawal in moderating the association between AS and PTSD symptom severity among a sample of treatment-seeking smokers with PTSD.

METHOD

Participants (n = 117) were enrolled in a randomized controlled trial for the treatment of PTSD and nicotine dependence. Cross-sectional data were randomly sampled from three different study time points. A series of multiple regression models were tested.

RESULTS

Results revealed main effects of both AS and withdrawal severity on PTSD severity after controlling for gender, assessment time-point, negative affectivity, and biochemically verified smoking (expired carbon monoxide). The interaction of AS and withdrawal was also significant, and appeared to be specific to PTSD avoidance and hyperarousal symptoms. However, contrary to expectations, the association between AS and PTSD symptoms was only significant at relatively lower levels of nicotine withdrawal.

CONCLUSIONS

These findings highlight the complex interplay between AS, nicotine withdrawal, and their synergistic effect in terms of the exacerbation of PTSD symptomology.

Short-term pain for long-term gain: the role of experiential avoidance in the relation between anxiety sensitivity and emotional distress

Research has provided evidence of an interactive effect between anxiety sensitivity (AS) and experiential avoidance (EA) in predicting both anxiety and posttraumatic stress (PTS) symptomatology. Additionally, theory suggests that EA alleviates distress in the short-term, but exacerbates it in the long-term. The present cross-sectional study was developed to replicate the noted findings and examine the interaction (EA × AS) in the context of an emotionally evocative task. It was predicted that, among high AS participants, high EA would (a) reduce the likelihood of experiencing short-term increases in negative affect following the task, and (b) increase the likelihood of anxiety and PTS symptomatology. Undergraduate participants (N=199) completed a battery of self-report questionnaires and an emotionally evocative task. As predicted, positive associations were observed between AS and both anxiety and PTS symptoms, but only among high EA participants. Additionally, AS only predicted increases in negative affect following the emotionally evocative task for those with lower levels of EA, thus providing empirical evidence of the affect regulatory function of EA among those who fear anxiety-related bodily sensations. These findings help to elucidate the motives for the use of avoidance among those high in AS. Conceptual and clinical implications are discussed.

Interactive Effects of Anxiety Sensitivity and Difficulties in Emotion Regulation: An Examination among Individuals in Residential Substance Use Treatment with Comorbid Posttraumatic Stress Disorder

Individuals with posttraumatic stress disorder (PTSD) exhibit deficits in cognitive and emotional processes. PTSD severity is positively associated with anxiety sensitivity (AS) and difficulties in emotion regulation, and difficulties in emotion regulation mediate the relation between AS and PTSD. However, previous research has not examined the interactive nature of these variables. Associations between PTSD, AS, and difficulties in emotion regulation were examined in patients with PTSD in a residential substance treatment program (N = 120). Conditional process analyses indicated an interactive effect of difficulties in emotion regulation and AS for predicting PTSD symptom severity. For individuals high in emotion regulation difficulties, PTSD symptom severity was high regardless of level of AS; conversely, for individuals high in AS, increased PTSD severity was observed regardless of level of emotion regulation difficulties. Results suggest directions for future research, including targeting patient specific cognitive-affective processes to enhance PTSD treatment response among substance dependent individuals.

Identification of anxiety sensitivity classes and clinical cut-scores in a sample of adult smokers: results from a factor mixture model

Anxiety sensitivity (AS), a multidimensional construct, has been implicated in the development and maintenance of anxiety and related disorders. Recent evidence suggests that AS is a dimensional-categorical construct within individuals. Factor mixture modeling was conducted in a sample of 579 adult smokers (M age=36.87 years, SD=13.47) to examine the underlying structure. Participants completed the Anxiety Sensitivity Index-3 and were also given a Structured Clinical Interview for DSM-IV-TR. Three classes of individuals emerged, a high AS (5.2% of the sample), a moderate AS (19.0%), and a normative AS class (75.8%). A cut-score of 23 to identify high AS individuals, and a cut-score of 17 to identify moderate-to-high AS individuals were supported in this study. In addition, the odds of having a concurrent anxiety disorder (controlling for other Axis I disorders) were the highest in the high AS class and the lowest in the normative AS class.

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.

Anxiety Sensitivity as a Moderator of the Association Between Premenstrual Symptoms and Posttraumatic Stress Disorder Symptom Severity

Experience of premenstrual symptoms may be an important factor involved in understanding posttraumatic stress disorder (PTSD) symptom vulnerability. Correlations between PTSD and premenstrual dysphoric disorder (PMDD) have been identified in epidemiological studies, however, the nature of this relation is not clear. The current study examined the incremental validity of premenstrual symptoms, as well as their interaction with anxiety sensitivity, in the prediction of PTSD symptom severity above and beyond other theoretically relevant covariates. A community sample of trauma-exposed women (N = 63) completed questionnaires assessing premenstrual symptoms, anxiety sensitivity, and neuroticism and were administered the Clinician-Administered PTSD Scale to assess PTSD symptom severity. A series of hierarchical linear regressions revealed that premenstrual symptoms uniquely predicted PTSD total, reexperiencing, avoidance, and hyperarousal symptoms above and beyond other theoretically relevant covariates (i.e., number of potentially traumatic events, neuroticism, panic attack history, and anxiety sensitivity). Additionally, anxiety sensitivity emerged as a moderator of the association between premenstrual symptoms and PTSD symptom severity such that greater premenstrual symptoms were associated with greater PTSD total, reexperiencing, and numbing symptom severity for individuals high, but not low, in anxiety sensitivity. Experience of premenstrual symptoms may be an important sex-specific mechanism involved in increasing vulnerability for PTSD symptoms, particularly among women high in anxiety sensitivity.

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.

Risk factors predicting posttraumatic stress reactions in adolescents after 2011 Van earthquake

OBJECTIVE

Our aims were to investigate the prevalence of PTSD, depression, anxiety-related disorders, and dissociative symptomotology, and to assess the risk factors for development of psychopathology among children and adolescents after the 2011 Van earthquake in Turkey.

METHODS

The screening was conducted among 738 participants at 6months post-earthquake using the CPTSD-Reaction Index, State and Trait Anxiety Inventory for Children, Screen for Child Anxiety Related Emotional Disorders, Child Depression Inventory, Childhood Anxiety Sensitivity Index, Metacognitions Questionnaire for Children, and Adolescent Dissociative Experiences Scale.

RESULTS

Less than half (40.69% of) of the participants reported severe levels of PTSD symptoms, 53.04% were at greater risk for developing an anxiety-related disorder, 37.70% met the criteria for clinical depression, and 36.73% revealed pathological levels of dissociative symptomotology. State-trait anxiety, and anxiety sensitivity were significant antecedents of psychopathology.

CONCLUSION

We concluded that anxiety sensitivity is a significant risk factor in various types of psychopathology, but metacognitions seem to have a limited utility in accounting for poor psychological outcomes in young survivors of earthquake.

Female vulnerability to the development of depression-like behavior in a rat model of intimate partner violence is related to anxious temperament, coping responses, and amygdala vasopressin receptor 1a expression

Exposure to violence is traumatic and an important source of mental health disturbance, yet the factors associated with victimization remain incompletely understood. The aim of the present study was to investigate factors related to vulnerability to depression-like behaviors in females. An animal model of intimate partner violence, which was previously shown to produce long-lasting behavioral effects in females as a result of male partner aggression, was used. The associations among the degree of partner aggression, the long-term consequences on depressive-like behavior, and the impact of the anxious temperament of the female were examined. In a separate group, pre-selected neural markers were evaluated in the amygdala and the lateral septum of females. Expression was examined by analyses of targeted candidate genes, serotonin transporter (slc6a4), vasopressin receptor 1a, (avpr1a), and oxytocin receptor (oxtr). Structural equation modeling revealed that the female's temperament moderated depressive-like behavior that was induced by cohabitation aggression from the male partner. More specifically, increased floating in the forced swim test following male aggression was most apparent in females exhibiting more anxiety-like behavior (i.e., less open arm exploration in an elevated plus-maze) prior to the cohabitation. Aggression reduced slc6a4 levels in the lateral septum. However, the interaction between partner aggression and the anxious temperament of the female affected the expression of avpr1a in the amygdala. Although, aggression reduced levels of this marker in females with high anxiety, no such pattern was observed in females with low anxiety. These results identify important characteristics in females that moderate the impact of male aggression. Furthermore, these results provide potential therapeutic targets of interest in the amygdala and the lateral septum to help improve post-stress behavioral pathology and increase resilience to social adversity.

Exploration of a factor mixture-based taxonic-dimensional model of anxiety sensitivity and transdiagnostic psychopathology vulnerability among trauma-exposed adults

The aim of this study was to evaluate the associations between a factor mixture-based taxonic-dimensional model of anxiety sensitivity (AS) and posttraumatic stress, panic, generalized anxiety, depression, psychiatric multimorbidity, and quality of life among a young adult sample exposed to traumatic stress (N = 103, n (females) = 66, M (age) = 23.68 years, SD (age) = 9.55). Findings showed support for the conceptual and operational utility of the AS taxonic-dimensional model with respect to concurrent transdiagnostic vulnerability among trauma-exposed adults. Specifically, relative to the low-AS group, the high-AS group demonstrated elevated levels of panic, depressive, and posttraumatic stress symptom severity as well as greater psychiatric multimorbidity and poorer quality of life. Furthermore, past-month MDD, GAD, PTSD, and panic attacks occurred nearly exclusively among the high-AS group. Continuous AS physical and psychological concerns scores were found to be significantly related to levels of panic and posttraumatic stress symptom severity, psychiatric multimorbidity as well as panic attack status only among the high-AS group and not among the low-AS group. Findings are discussed with respect to their implications for the conceptual and operational utility of the FMM-based taxonic-dimensional model of AS, related vulnerability for psychopathology in the context of trauma, and the clinical implications of these findings for assessment and intervention.

Anxiety Sensitivity, Emotional Avoidance, and PTSD Symptom Severity Among Crack/Cocaine Dependent Patients in Residential Treatment

High rates of co-occurring posttraumatic stress disorder (PTSD) have been found among patients receiving treatment for substance use disorders (SUD), and there is evidence that this particular co-occurrence is associated with negative SUD treatment outcomes. Thus, there is utility in establishing the role of psychological vulnerabilities related to PTSD within SUD populations, with the goal of ultimately informing targeted interventions and improving clinical outcomes. Anxiety sensitivity (AS) and emotional avoidance (EA) may be two important factors in this regard, as both have been found to demonstrate associations with posttraumatic stress in other clinical and nonclinical populations. To expand upon this literature, the current study examined the associations between AS and EA and PTSD symptom severity in a sample of traumatic event-exposed crack/cocaine dependent patients in residential SUD treatment (n = 62), as well as the extent to which EA mediated the relation between AS and PTSD symptom severity. As hypothesized, AS and EA were associated with PTSD symptom severity above and beyond the effects of gender and non-specific anxiety symptoms. However, the hypothesis that EA would mediate the relation between AS and PTSD symptom severity was only partially supported. Implications of these findings for understanding and treating co-occurring SUD-PTSD are discussed.

Anxiety sensitivity, asthma control, and quality of life in adults with asthma

OBJECTIVE

The aim of this study was to examine the role of anxiety sensitivity (AS) in terms of asthma control and asthma-related quality of life in a sample of adults with a physician-verified diagnosis of asthma.

METHODS

Self-report measures assessing psychological and asthma symptoms were mailed to 368 asthma patients from a community allergy and asthma office who had been seen for a physician follow-up visit between 1 January 2009 and 1 January 2010. Participants in the current study were 127 asthma patients (74% female; M(age) = 43.4 years, SD = 12.3) who completed and returned the self-report measures.

RESULTS

The results indicated that, after controlling for gender, age, negative affect, and number of comorbid medical problems, the physical concerns factor of AS (AS-Physical Concerns) significantly predicted asthma control and all domains of asthma-related quality of life (symptoms, activity limitations, emotional functioning, and environmental stimuli).

CONCLUSIONS

These findings replicate and extend previous research and indicate that the fear of physical sensations negatively affects both asthma control and quality of life. These findings also suggest that targeting the AS-Physical Concerns may be a novel way to improve asthma control and quality of life.

The interplay between physical activity and anxiety sensitivity in fearful responding to carbon dioxide challenge

OBJECTIVE

Physical activity may confer protective effects in the development of anxiety and its disorders. These effects may be particularly strong among individuals who have elevated levels of anxiety sensitivity (AS; i.e., the fear of somatic arousal), an established cognitive-based risk factor for anxiety and its disorders. The present study performed a laboratory test of the interplay between physical activity and AS.

METHODS

The participants were adults free of Axis I psychopathology (n = 145) who completed measures of physical activity and AS before undergoing a recurrent 20% carbon dioxide-enriched air (CO(2)) challenge.

RESULTS

Consistent with the hypothesis, physical activity was significantly related to CO(2) challenge reactivity among persons with elevated levels of AS, at high levels of physical activity (p < .001) but not at low levels of physical activity (p = .90). Also consistent with hypothesis, irrespective of the level of physical activity, physical activity did not relate significantly to CO(2) challenge reactivity among persons with normative levels of AS (p = .28).

CONCLUSIONS

These findings provide novel empirical insight into the role that physical activity may play in terms of resiliency for the development of anxiety disorders. Specifically, the protective effects of physical activity may only be evident at higher doses and among persons who are at increased risk of developing anxiety disorders because they have elevated AS.

Anxiety sensitivity as a mediator of the relationship between moderate-intensity exercise and coping-oriented marijuana use motives

The present study examined the working hypothesis that moderate-intensity exercise is associated with coping-oriented marijuana use motives through its association with the fear of somatic arousal (ie, anxiety sensitivity). Using data from 146 young adult current marijuana users, we found evidence consistent with this hypothesis. Specifically, moderate-intensity exercise was associated with coping-oriented use motives, even after controlling for frequency of current marijuana use and other co-occurring marijuana use motives. This relationship became nonsignificant after entering anxiety sensitivity as an additional predictor variable, denoting a putative mediational role for this cognitive factor. These findings extend previous work and offer support for the potential utility of moderate-intensity aerobic exercise for the treatment of marijuana use problems.

Dimensional, categorical, or dimensional-categories: testing the latent structure of anxiety sensitivity among adults using factor-mixture modeling

The present study tested multiple, competing latent structural models of anxiety sensitivity (AS), as measured by the Anxiety Sensitivity Index-3 (ASI-3; Taylor et al., 2007). Data were collected from 3 sites in North America (N=634). Participants were predominantly university students (M=21.3 years, SD=5.4). ASI-3 data were evaluated using an integration of mixture modeling and confirmatory factor analysis-factor mixture modeling (FMM; Muthén, 2008). Results supported a 2-class 3-factor partially invariant model of AS. Specifically, the FMM analyses indicated that AS is a taxonic (two-class) variable, and that each categorical class has a unique multidimensional factor structure. Consistent with the specific point-prediction regarding the hypothesized parameters of the putative latent class variable, FMM indicated that the putatively "high-risk" subgroup of cases or latent form of AS composed approximately 12% of the studied sample whereas the putatively "normative" subgroup of cases or latent form of AS composed 88% of the sample. In addition, the AS Physical and Psychological Concerns subscales, but not the Social Concerns subscale, most strongly discriminated between the two latent classes. Finally, comparison of continuous levels of AS Physical and Psychological Concerns between FMM-derived AS latent classes and independent clinical samples of patients with anxiety disorders provided empirical support for the theorized taxonic-dimensional model of AS and anxiety psychopathology vulnerability. Findings are discussed in regard to the implications of this and related research into the nature of AS and anxiety psychopathology vulnerability.

The role of anxiety sensitivity in terms of asthma control: a pilot test among young adult asthmatics

The aim of the present pilot investigation was to examine the role of specific subfactors of anxiety sensitivity (physical, cognitive, and social concerns) in terms of asthma control among a young adult sample (N = 56; M age = 20.0; SD = 3.9; Range = 18-45 years). Results indicated that, after controlling for gender, cigarette smoking status, and negative affectivity, the physical concerns factor of anxiety sensitivity, relative to cognitive and social concern factors, significantly predicted asthma control. These findings support the theory that fear of physical sensations is associated with poorer asthma control and suggest that targeting the physical concerns facet of anxiety sensitivity may be a novel way to improve asthma control.

Fear of anxiety as a partial mediator of the relation between trauma severity and PTSD symptoms

Fear of anxiety has previously been found to be a predictor of overall symptoms of posttraumatic stress disorder (PTSD). The current exploratory study examines the relationship between fear of anxiety and symptoms of PTSD in a sample of adults exposed to Hurricane Katrina. Fear of anxiety was found to partially mediate the relationship between the severity of trauma and the severity of PTSD. Further, this mediation was found to operate differently by gender, with the mediation holding true for men but not for women. For both men and women, fear of anxiety was positively correlated with PTSD symptoms.

Anxiety sensitivity and PTSD symptom severity are reciprocally related: evidence from a longitudinal study of physical trauma survivors

Cross-lagged panel analysis of interview data collected from survivors of traumatic physical injury (N = 677) was used to examine the temporal relationship between anxiety sensitivity and posttraumatic stress disorder (PTSD) symptom severity. The 2 constructs were assessed at 3 time points: within days of physical injury, at 6-month follow-up, and at 12-month follow-up. Results indicated that anxiety sensitivity and PTSD symptom severity were reciprocally related such that anxiety sensitivity predicted subsequent PTSD symptom severity, and symptom severity predicted later anxiety sensitivity. Findings have both theoretical and clinical implications.

Temporal and structural dynamics of anxiety sensitivity in predicting fearful responding to a 35% CO2 challenge

The current study assessed the incremental prediction of anxiety sensitivity (AS) in both taxonic (categorical) and dimensional representations at various time points before and after a single vital capacity inhalation of a 35% CO(2), 65% balanced O(2) gas mixture. Participants were 128 young adults screened for a history of panic attacks. By controlling for traitwise factors including state anxiety and testing both categorical and continuous conceptualizations of the AS construct at various timepoints, the present report was able to evaluate the temporal and structural dynamics of AS in relation to fearful responding to the challenge. Relevant variables were evaluated in a hierarchical linear regression framework, and it was found that a continuous conceptualization of AS provided incremental predictive validity above and beyond trait anxiety immediately post-challenge, while a categorical representation of AS was equivalent to a continuous model of AS at post-challenge but outperformed a continuous model at follow-up. These data provide basic but important evidence suggesting that AS is uniquely associated with anxious responding to a 35% CO(2) challenge, and that categorical representations of AS should be considered in biological challenge studies.

Comorbid panic attacks among individuals with posttraumatic stress disorder: associations with traumatic event exposure history, symptoms, and impairment

Little is known about the prevalence of panic attacks in PTSD and their influence on symptom severity and disability. Utilizing the National Comorbidity Survey-Replication data, respondents meeting DSM-IV criteria for past year PTSD (n=203) with and without comorbid panic attacks were compared across various dimensions. Past year panic attacks were found among 35% of the sample and were associated with greater PTSD-related disability and less time spent at work. Panic attacks were also associated with greater prevalence of comorbid depression, substance abuse/dependence, medically unexplained chronic pain, number of anxiety disorders and lifetime traumatic events, PTSD reexperiencing and avoidance/numbing symptoms, and treatment-seeking related to traumatic stress reactions. Multivariate analyses revealed that panic attacks were one of the only unique predictors of severe PTSD-related disability. Overall, findings suggest that panic attacks are common among individuals with PTSD; therapeutic strategies targeting panic in this population may be of significant benefit.

Evaluating emotional sensitivity and tolerance factors in the prediction of panic-relevant responding to a biological challenge

The current study investigated anxiety sensitivity, distress tolerance (Simons & Gaher, 2005), and discomfort intolerance (Schmidt, Richey, Cromer, & Buckner, 2007) in relation to panic-relevant responding (i.e., panic attack symptoms and panic-relevant cognitions) to a 10% carbon dioxide enriched air challenge. Participants were 216 adults (52.6% female; M(age)=22.4, SD=9.0). A series of hierarchical multiple regressions was conducted with covariates of negative affectivity and past year panic attack history in step one of the model, and anxiety sensitivity, discomfort intolerance, and distress tolerance entered simultaneously into step two. Results indicated that anxiety sensitivity, but not distress tolerance or discomfort intolerance, was significantly incrementally predictive of physical panic attack symptoms and cognitive panic attack symptoms. Additionally, anxiety sensitivity was significantly predictive of variance in panic attack status during the challenge. These findings emphasize the important, unique role of anxiety sensitivity in predicting risk for panic psychopathology, even when considered in the context of other theoretically relevant emotion vulnerability variables.

Attributional style and anxiety sensitivity as maintenance factors of posttraumatic stress symptoms: A prospective examination of a diathesis-stress model

Diathesis-stress models of posttraumatic stress disorder (PTSD) assert that traumatic events function as stressors that interact with vulnerabilities to influence the development of PTSD. The present study prospectively examined negative attributional style (NAS) and anxiety sensitivity (AS) as maintenance factors for PTSD in female adult sexual assault victims. A diathesis-stress model was tested by examining interactions between the vulnerabilities and negative life events. The present study included both the traditional three-factor model of PTSD (re-experiencing, avoidance and emotional numbing, and arousal) and the dysphoria four-factor model of PTSD (re-experiencing, avoidance, arousal, and dysphoria). Robust regression analyses revealed that negative life events at Time 2 significantly predicted increases in all clusters of the three-factor model (i.e., re-experiencing, avoidance and numbing, and arousal) and the re-experiencing, arousal, and dysphoria clusters of the four-factor model (but not avoidance). Neither NAS nor AS significantly independently predicted any of the symptom clusters for either model. Both NAS and AS interacted with negative life events to predict increases in the avoidance and numbing symptoms. However, examination of the dysphoria four-factor model of PTSD revealed that the NAS and AS interactions with negative life events only predicted dysphoria symptoms.

Anxiety sensitivity and posttrauma stress symptoms in female undergraduates following a campus shooting

Participants were recruited from female undergraduate students participating in an ongoing longitudinal study at the time of a campus shooting. Eighty-five percent (N = 691) of the 812 students who were invited to participate in the current study completed questionnaires an average of 27 days following a campus shooting. In a mixed cross-sectional and longitudinal design, the cognitive and the physical concerns dimensions of postshooting anxiety sensitivity accounted for unique variance in posttrauma stress symptom severity (cross-sectional), after controlling for preshooting psychological symptoms (longitudinal). The cognitive concerns dimension showed the strongest relationship. Anxiety sensitivity also appeared to moderate the relationships of hyperarousal symptoms with reexperiencing and numbing symptoms.

Integrating anxiety sensitivity, distress tolerance, and discomfort intolerance: a hierarchical model of affect sensitivity and tolerance

The purpose of the present investigation was to concurrently examine the latent dimensional and hierarchical structure of anxiety sensitivity (AS) and two key theoretically relevant and related affect (in)tolerance and sensitivity constructs: distress tolerance and discomfort intolerance. These constructs were measured using the Anxiety Sensitivity Index (Reiss, Peterson, Gursky, & McNally, 1986), the Distress Tolerance Scale (Simons & Gaher, 2005), and the Discomfort Intolerance Scale (Schmidt, Richey, & Fitzpatrick, 2006). A total of 229 individuals (124 females; M(age)=21.0 years, SD=7.5) without current Axis I psychopathology participated by completing a battery of self-report questionnaires. A two-stage exploratory factor analysis was conducted to examine the lower- and higher-order latent structural relations among the variables. The factor solution was subsequently evaluated in relation to negative affectivity, anxious arousal, and anhedonic depression. AS and distress tolerance appeared to be related to one another as distinct lower-order facets of a common higher-order affect tolerance and sensitivity factor, whereas discomfort intolerance did not appear to demonstrate similar relations with either AS or distress tolerance at the lower-order or higher-order levels. A unique pattern of association with theoretically-relevant criterion variables was observed between the affect tolerance and sensitivity higher-order factor, the AS and distress tolerance lower-order factors, and the discomfort intolerance factor. Findings are discussed in the context of theoretical and clinical implications and future directions for the study of affect tolerance and sensitivity in relation to emotional vulnerability.

The role of anxiety sensitivity and difficulties in emotion regulation in posttraumatic stress disorder among crack/cocaine dependent patients in residential substance abuse treatment

Current research suggests the importance of anxiety sensitivity (AS) in the risk for posttraumatic stress disorder (PTSD), and a growing body of research has demonstrated that difficulties in emotion regulation may also play a role. This study examined the unique relationships between AS dimensions, difficulties in emotion regulation, and a probable PTSD diagnosis among a sample of inner-city crack/cocaine dependent patients in residential substance abuse treatment. Probable PTSD participants exhibited higher levels of the AS dimension of social concerns and emotion regulation difficulties. Emotion regulation difficulties reliably distinguished probable PTSD participants from non-PTSD participants above and beyond both anxiety symptom severity and the AS dimension of social concerns. Further, social concerns did not account for unique variance when difficulties in emotion regulation was entered into the model. Results provide support for the central role of difficulties in emotion regulation relative to AS dimensions in the prediction of PTSD within a crack/cocaine dependent population.

Laboratory test of a novel structural model of anxiety sensitivity and panic vulnerability

The current study evaluated a novel latent structural model of anxiety sensitivity (AS) in relation to panic vulnerability among a sample of young adults (N=216). AS was measured using the 16-item Anxiety Sensitivity Index (ASI; Reiss, Peterson, Gursky, & McNally, 1986), and panic vulnerability was indexed by panic attack responding to a single administration of a 4-minute, 10% CO(2) challenge. As predicted, vulnerability for panic attack responding to biological challenge was associated with dichotomous individual differences between taxonic AS classes and continuous within-taxon class individual differences in AS physical concerns. Findings supported the AS taxonic-dimensional hypothesis of AS latent structure and panic vulnerability. These findings are discussed in terms of their theoretical and clinical implications.

Anxiety sensitivity and anxiety and depressive symptoms in the prediction of early smoking lapse and relapse during smoking cessation treatment

INTRODUCTION

The present investigation examined whether anxiety sensitivity, relative to anxiety and depressive symptoms, was related to duration to early smoking lapse and relapse (during first 2 weeks postquit) among daily smokers receiving smoking cessation treatment.

METHODS

Participants included 123 daily cigarette smokers (84 women; M(age) = 45.93 years, SD = 10.34) living in the Halifax Regional Municipality in Nova Scotia, Canada.

RESULTS

Anxiety sensitivity was significantly associated with an increased risk of early smoking lapse (i.e., any smoking behavior) at days 1, 7, and 14 following the quit day. Such effects were evident above and beyond the variance accounted for by gender, nicotine dependence, and nicotine withdrawal symptoms, as well as the shared variance with prequit (baseline) anxiety and depressive symptoms. In contrast to expectation, anxiety sensitivity was not related to smoking relapse (i.e., seven consecutive days of smoking) during the first 2 weeks of quitting.

DISCUSSION

Results are discussed in terms of better understanding the role of anxiety sensitivity, along with other affective vulnerability processes, in early problems encountered during a quit attempt.

Evaluation of anxiety sensitivity among daily adult smokers using item response theory analysis

The present investigation applied Item Response Theory (IRT) methodology to the 16-item Anxiety Sensitivity Index (ASI) [Reiss, S., Peterson, R. A., Gursky, M., & McNally, R. J. (1986). Anxiety sensitivity, anxiety frequency, and the prediction of fearfulness. Behaviour Research and Therapy, 24, 1-8] for a sample of 475 daily adult smokers (52% women; M(age)=26.9, S.D.=11.1, range=18-65). Using non-parametric item response analysis, all 16 ASI items were evaluated. Evaluation of the option characteristic curves for each item revealed 4 poorly discriminating ASI items (1: "It is important not to appear nervous;" 5: "It is important to me to stay in control of my emotions;" 7: "It embarrasses me when my stomach growls;" 9: "When I notice my heart beating rapidly, I worry that I might be having a heart attack"), which were dropped from analysis. Upon repeat analysis, the remaining items appeared to make adequate separations within levels of anxiety sensitivity in this sample. Graded response modeling data indicated important differences in ASI items' capacity to discriminate between, and provide information about, latent levels of anxiety sensitivity. Specifically, three items best discriminated and provided the most information regarding latent levels of AS-items 3, 15, and 16. Items 1, 5, 7, and 9 were omitted due to their limited capacity to discriminate between latent levels of anxiety sensitivity; items 8, 12, and 13 also performed poorly. Overall, current findings suggest that evaluation of anxiety sensitivity among adult smokers using the 16-item ASI may usefully choose to focus on items that performed well in these IRT analyses (items: 2, 3, 4, 6, 10, 11, 14, 15, and 16).
