Abstract
BACKGROUND AND OBJECTIVES Anxiety sensitivity (AS) refers to a fear of the negative implications of anxiety, and arises due to gene-environment interactions. We investigated whether genetic variation in two neuropeptides implicated in the stress response, neuropeptide Y (NPY) and pituitary adenylate cyclase-activating polypeptide receptor 1, interacted with childhood trauma (CT) to influence AS. DESIGN AND METHODS This cross-sectional study examined the CT x genetic variant effects on AS in 951 adolescents who self-identified as Xhosa or South African Colored (SAC) ethnicity. RESULTS In Xhosa females, the NPY rs5573 A allele and rs3037354 deletion variant were associated with increased (p = 0.035) and decreased (p = 0.034) AS, respectively. The interaction of CT and the NPY rs5574 A allele increased AS in SAC female participants (p = 0.043). The rs3037354 deletion variant protected against AS with increased CT in SAC male participants (p = 0.011). CONCLUSIONS The NPY rs5574 A allele and rs3037354 deletion variant interact with CT to act as risk and protective factors, respectively, for AS in an ethnicity- and sex- differentiated manner. Our results reaffirm the role of NPY and gene-environment interactions in anxiety-related behaviors and reinforce the need for psychiatric genetics studies in diverse populations.

Abstract
The present study examined the factor structure, invariance properties, reliability, and validity of the Anxiety Sensitivity Index-3 (ASI-3, Taylor et al., 2007). Participants were recruited from a large, ethnically diverse southwestern university (n = 3651; 77.8% female; Mage = 22.06 years; 28% non-Hispanic White). Findings supported a bifactor structure for the ASI-3, which demonstrated measurement invariance across sex, race/ethnicity, age, and sexual minority status. Furthermore, the ASI-3 demonstrated strong reliability and validity, with the anxiety sensitivity general and specific factors (physical, cognitive, and social concerns) evidencing unique patterns of relations with symptoms of depression, suicidality, anxious arousal, and social anxiety. Clinically, these findings generally support the validity of the ASI-3 in measuring anxiety sensitivity across sex, age, race/ethnicity, and sexual minority status. Future work is needed to better understand the role anxiety sensitivity plays within specific demographic subgroups, particularly African-Americans, Asian Americans, and sexual minorities.

Abstract
The anxiolytic and antidepressant effects of regular physical exercise have been well documented, though the mechanisms through which exercise alleviates symptoms of emotion disorders require further investigation. Mounting research indicates that exercise reduces anxiety sensitivity, a known vulnerability factor for the development and maintenance of psychological disorders, presumably via repeated exposure to feared somatic sensations. The purpose of the present study was to examine whether anxiety sensitivity mediates the relation between exercise frequency and symptoms of anxiety and depression. A large community sample of 955 volunteers completed a demographic questionnaire, the Anxiety Sensitivity Index-3, and the Brief Symptom Inventory-18. Exercise frequency significantly predicted anxiety sensitivity, anxiety, depression, and somatization scores. Mediation analyses indicated that anxiety sensitivity mediated the association between exercise frequency and anxiety, depression, and somatization symptoms. The findings provide further support for the association between exercise and negative affective states and suggest that anxiety sensitivity may be one mechanism through which exercise reduces emotional disorder symptomology. The implications of these findings and recommendations for future research are discussed.

Abstract
Numerous studies have provided evidence for the effectiveness of cognitive behavioral therapy (CBT) on panic disorders (PDs). There has also been growing attention on brief CBT with regard to delivering intensive treatment efficiently. This study investigated the essential parts of mindfulness-based brief CBT to optimize treatment benefits.A total of 37 patients were retrospectively enrolled in this study. They were recruited from the anxiety/panic/fear clinic of Seoul National University Hospital. The patients participated in group CBT once a week for a total of 4 sessions over a 4-week period, when they were assessed using the Panic Disorder Severity Scale (PDSS), Anxiety Sensitivity Index-Revised (ASI-R), Albany Panic and Phobia Questionnaire (APPQ), State-Trait Anxiety Inventory (STAI), Beck Anxiety Inventory (BAI), Beck Depression Inventory (BDI), and Yale-Brown Obsessive Compulsive Scale (Y-BOCS) before and after brief CBT. Twenty-nine patients completed the 1-month follow-up.There were significant reductions in PDSS (P < .001), ASI-R-fear of respiratory symptoms (P = .006), ASI-R-fear of publicly observable anxiety reaction (P = .002), ASI-R-fear of cardiovascular symptoms (P < .001), ASI-R-fear of cognitive dyscontrol (P = .001), ASI-R-Total (P < .001), APPQ-Agoraphobia (P = .003), APPQ-Total (P = .028), STAI-State anxiety (P < .001), STAI-Trait anxiety (P = .002), BAI (P = .003), and BDI (P < .001) scores. We also found significant associations between ASI-R-fear of cardiovascular symptoms, ASI-R-Total, and changes in PDSS scores. A stepwise multiple linear regression analysis indicated that anxiety sensitivity for fear of cardiovascular symptoms predicted an improvement in panic severity (β = 0.513, P = .004).Our findings suggested that behavioral aspects, especially physiological symptom control, needed to be considered in brief, intensive CBT for PD. The results also suggested that a mindfulness-based brief CBT approach might be particularly helpful for patients with PD who have severe cardiovascular symptoms.

Abstract
Anxiety sensitivity (AS) is characterised by the fear of anxiety-related symptoms and is a risk factor for the development of anxiety-related disorders. We examined whether genetic variation in three stress response genes, CRHR1, NR3C1, and FKBP5, interact with childhood trauma (CT) to predict AS in South African adolescents. Xhosa (n = 634) and Coloured (n = 317) students completed self-report measures of AS and CT, and a total of eighteen polymorphisms within CRHR1, NR3C1, and FKBP5 were genotyped. Differences in AS based on genetic variation and CT were analysed within population and gender groups using multiple linear regression. Associations were found between AS and FKBP5 rs9296158 (p = 0.025) and rs737054 (p = 0.045) in Coloured males. Analysis of gene x CT interactions indicated that NR3C1 rs190488 CC-genotype, NR3C1 rs10482605 G-allele addition, and FKBP5 rs3800373 C-allele addition protect against AS with increasing CT in Xhosa females (p = 0.009), Xhosa males (p = 0.036) and Coloured males (p = 0.049), respectively. We identified two different protective single nucleotide polymorphism (SNP) combinations in a four-SNP CRHR1 haplotype in Coloured males. An analysis of the interaction between CT and a six-SNP FKBP5 haplotype in Coloured males revealed both protective and risk allelic combinations. Our results provide evidence for the influence of both genetic variation in CRHR1, NR3C1 and FKBP5, as well as CT x SNP interactions, on AS in South African adolescents. This study reinforces the importance of examining the influence of gene-environment (G X E) interactions within gender and population groups.

Abstract
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.

Abstract
Anxiety sensitivity (AS) is a risk factor for the development of anxiety disorders in youth. To date, the applicability of the Childhood Anxiety Sensitivity Index (CASI) in youth from a low or middle income country (LMIC) setting on the African continent has not been assessed. A representative sample of 1149 secondary school learners from 29 schools in Cape Town, South Africa, participated in the study. Participants completed the CASI on a single occasion. One-, two-, and four-factor models of the CASI were assessed. A one-factor solution that comprised items predominantly represented by physical concerns appeared to provide the best fit to our data, however, relatively low variance (26%) was explained. Subsequent item deletion resulted in a 9-item ‘physical concerns’ factor that showed good construct reliability (0.83) but also explained a low amount of variance (35%). In terms of gender, a one-factor model provided the best fit, however, low variance was explained (i.e., 25%). Configural, metric and scalar invariance of the CASI by gender was determined. Our results suggest that the 18-item CASI is not applicable to our target population and may require adaptation in this population; however, replication of this study in other multicultural adolescent samples in South Africa is first needed to further assess the validity of the AS construct as measured by the CASI.

Abstract
OBJECTIVE The demographic characteristics, maternal parity and personal traits of pregnant women have been frequently studied predictors of fear of childbirth (FOC). The aim of this study was to examine the role of demographic variables, expected pain level, trait anxiety and anxiety sensitivity in FOC among nulliparous and multiparous women in the last trimester of pregnancy. METHOD Two-hundred pregnant women completed a booklet with questionnaires including the Wijma Delivery Expectancy/Experience Questionnaire (W-DEQ), Anxiety Sensitivity Index (ASI), The State - Trait Anxiety Inventory (STAI) and questions on expected labor pain and demographics. RESULTS Results showed that FOC was higher amongst nulliparous women, but FOC level was not associated with other demographic variables. Different predictors were established in nulliparous and multiparous women. While higher intensity of expected labor pain and anxiety sensitivity (dimension physical concern) were significant predictors in both groups, trait anxiety was significant for the first-time mothers only. CONCLUSION Amongst all women, anxiety sensitivity (physical concerns dimension) was identified as an important vulnerability factor for FOC. As such, the level of anxiety sensitivity, and any resulting fear or expectations of pain, should be assessed in expectant mothers by clinicians in prenatal settings. Furthermore, anxiety sensitivity should be an important target for psychological interventions aimed at managing FOC.

Abstract
OBJECTIVE Panic-spectrum psychopathology (denoting panic attacks and panic disorder) is highly prevalent in chronic obstructive pulmonary disease (COPD), and the cognitive model of panic has been proposed as an explanation of this high prevalence. In the current cross-sectional study we investigated factors predicting panic-spectrum psychopathology in COPD, and hypothesized that, consistent with the cognitive model, both the catastrophic interpretation of shortness of breath and elevated anxiety sensitivity would be significant predictors when variance shared with confounding variables was controlled. METHODS Sixty-two participants with COPD were interviewed with the Anxiety Disorders Interview Schedule for DSM-IV, Panic Disorder section, and completed measures of interpretation of breathing difficulty, anxiety sensitivity, anxiety, depression, disease-specific quality of life, and stressful life events. Objective disease severity was measured using forced expiratory volume in the first second. RESULTS Direct logistic regression was performed, and worse depressive symptoms, more catastrophic interpretations of shortness of breath, higher anxiety sensitivity, higher magnitude of recent stressful life events, and worse disease severity were each found to be significant unique predictors of panic-spectrum psychopathology in COPD after shared variance was controlled. CONCLUSIONS The results of the study provide support for the cognitive model of panic, and also suggest a diathesis-stress explanation of the development of panic-spectrum psychopathology in COPD. The findings have implications for future preventative psychological interventions.

Abstract
Recently, Fava and Morton (2009) described what they termed a 'causal model' of panic disorder (Causal modeling of panic disorder theories, Clinical Psychology Review, 29, 623-637). We examined several critical tenets of this proposed model, and offer significant revisions. Our revised causal model includes elements that have received empirical support, and exclude those with known limitations in explaining the etiology and treatment of panic disorder. Chief among these revisions are (1) an increased emphasis on anxiety sensitivity, (2) elimination of the more general psychodynamic conceptualization in favor of empirically supported findings regarding early attachment, and (3) placing biological and psychophysiological reactions as outcomes of false alarm threat, rather than causal mechanisms of panic.

Abstract
Anxiety sensitivity (AS) refers to a person’s tendency to fear anxiety-related symptoms due to the belief that these symptoms may have harmful consequences. The most widely used operationalization of AS in adults is the Anxiety Sensitivity Index (ASI). The factor structure, gender stability, and psychometric properties of the ASI in a sample of Croatian adults ( N = 984) were evaluated. Results confirm the multidimensional and hierarchical structure of the ASI, which consisted of three lower-order factors (Physical Concerns, Psychological Concerns, and Social Concerns) and a single higher-order factor, AS. Furthermore, the achievement of normative scores for the ASI in a Croatian adult sample demonstrates the cross-national stability of the ASI. Reliability coefficients for the ASI, Physical Concerns, and Psychological Concerns are high and satisfactory in the total sample and for both genders. Overall, the results confirmed the cross-national stability, gender stability, reliability, and validity of the ASI in a sample of Croatian adults.
