  • Anxiety Sensitivity Index (ASI-3) subscales predict unique variance in Anxiety and depressive symptoms
    Journal of anxiety disorders, 2013
    Co-Authors: Janine V. Olthuis, Margo C. Watt, Sherry H. Stewart
    Abstract:

    Anxiety Sensitivity (AS) has been implicated in the development and maintenance of a range of mental health problems. The development of the Anxiety Sensitivity Index - 3, a psychometrically sound Index of AS, has provided the opportunity to better understand how the lower-order factors of AS - physical, psychological, and social concerns - are associated with unique forms of psychopathology. The present study investigated these associations among 85 treatment-seeking adults with high AS. Participants completed measures of AS, Anxiety, and depression. Multiple regression analyses controlling for other emotional disorder symptoms revealed unique associations between AS subscales and certain types of psychopathology. Only physical concerns predicted unique variance in panic, only cognitive concerns predicted unique variance in depressive symptoms, and social Anxiety was predicted by only social concerns. Findings emphasize the importance of considering the multidimensional nature of AS in understanding its role in Anxiety and depression and their treatment.

  • Confirmatory Factor Analysis of the Childhood Anxiety Sensitivity Index: A Gender Comparison
    Cognitive behaviour therapy, 2010
    Co-Authors: Kristi D. Wright, Sherry H. Stewart, Elizabeth N. Mclaughlin, Gordon J.g. Asmundson, Donald R. Mccreary, M. Nancy Comeau, Trudi M. Walsh
    Abstract:

    The Childhood Anxiety Sensitivity Index (CASI) is an 18-item self-report tool designed to measure the construct of Anxiety Sensitivity (i.e. the belief that Anxiety may have harmful consequences such as sickness, embarrassment, or loss of control) in children and adolescents. Previous factor analytic examinations of the CASI have produced varied results. Gender may play a role in this observed variability. In an effort to confirm the factor structure of the measure across gender, CASI items for 671 children and adolescents were subjected to confirmatory factor analysis. Results indicated that for boys two-, three-, and four-factor structures provided a relatively good fit to the data, with the three-factor structure emerging as having the best fit overall. In contrast, for girls only the three-factor structure fitted the data well. Direct comparison of fit of the three-factor model across gender provided evidence to support the notion that childhood Anxiety Sensitivity is similar in structure across gender.

  • childhood Anxiety Sensitivity Index factors predict unique variance in dsm iv Anxiety disorder symptoms
    Cognitive Behaviour Therapy, 2007
    Co-Authors: Elizabeth N. Mclaughlin, Sherry H. Stewart, Steven Taylor
    Abstract:

    Anxiety Sensitivity (AS) is an established cognitive risk factor for Anxiety disorders. In children and adolescents, AS is usually measured with the Childhood Anxiety Sensitivity Index (CASI). Factor analytic studies suggest that the CASI is comprised of 3 lower-order factors pertaining to Physical, Psychological and Social Concerns. There has been little research on the validity of these lower-order factors. We examined the concurrent and incremental validity of the CASI and its lower-order factors in a non-clinical sample of 349 children and adolescents. CASI scores predicted symptoms of DSM-IV Anxiety disorder subtypes as measured by the Spence Children's Anxiety Scale (SCAS) after accounting for variance due to State-Trait Anxiety Inventory scores. CASI Physical Concerns scores incrementally predicted scores on each of the SCAS scales, whereas scores on the Social and Psychological Concerns subscales incrementally predicted scores on conceptually related symptom scales (e.g. CASI Social Concerns scores predicted Social Phobia symptoms). Overall, this study demonstrates that there is added value in measuring AS factors in children and adolescents.

  • Robust dimensions of Anxiety Sensitivity: Development and initial validation of the Anxiety Sensitivity Index-3
    Psychological assessment, 2007
    Co-Authors: Steven Taylor, Michael J. Zvolensky, Brett J. Deacon, Brian J. Cox, Bonifacio Sandín, Jonathan S. Abramowitz, Richard G. Heimberg, Deborah Roth Ledley, Robert M. Holaway, Sherry H. Stewart
    Abstract:

    Accumulating evidence suggests that Anxiety Sensitivity (fear of arousal-related sensations) plays an important role in many clinical conditions, particularly Anxiety disorders. Research has increasingly focused on how the basic dimensions of Anxiety Sensitivity are related to various forms of psychopathology. Such work has been hampered because the original measure--the Anxiety Sensitivity Index (ASI)--was not designed to be multidimensional. Subsequently developed multidimensional measures have unstable factor structures or measure only a subset of the most widely replicated factors. Therefore, the authors developed, via factor analysis of responses from U.S. and Canadian nonclinical participants (n=2,361), an 18-item measure, the ASI-3, which assesses the 3 factors best replicated in previous research: Physical, Cognitive, and Social Concerns. Factorial validity of the ASI-3 was supported by confirmatory factor analyses of 6 replication samples, including nonclinical samples from the United States and Canada, France, Mexico, the Netherlands, and Spain (n=4,494) and a clinical sample from the United States and Canada (n=390). The ASI-3 displayed generally good performance on other indices of reliability and validity, along with evidence of improved psychometric properties over the original ASI.

  • Refinement of Anxiety Sensitivity measurement: The Short Scale Anxiety Sensitivity Index (SSASI)
    Psychiatry research, 2018
    Co-Authors: Michael J. Zvolensky, Lorra Garey, Thomas A. Fergus, Matthew W. Gallagher, Andres G. Viana, Justin M. Shepherd, Nubia A. Mayorga, Lance P. Kelley, Jackson O. Griggs, Norman B. Schmidt
    Abstract:

    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.

  • Towards a greater understanding of Anxiety Sensitivity across groups: The construct validity of the Anxiety Sensitivity Index-3.
    Psychiatry research, 2018
    Co-Authors: Charles Jardin, Lorra Garey, Nubia A. Mayorga, Jafar Bakhshaie, Daniel J. Paulus, Brooke Y. Kauffman, Kara Manning, Michael J. Zvolensky
    Abstract:

    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.

  • evaluation of the Anxiety Sensitivity Index 3 among treatment seeking smokers
    Psychological Assessment, 2015
    Co-Authors: Samantha G Farris, Norman B. Schmidt, Angelo M Dibello, Nicholas P Allan, Julianna Hogan, Michael J. Zvolensky
    Abstract:

    The Anxiety Sensitivity Index-3 (ASI-3; Taylor et al., 2007) is a self-report assessment of Anxiety Sensitivity, reflecting an individual's tendency to misinterpret the meaning of Anxiety-relevant sensations. Despite this construct being related to a wide array of clinically significant smoking maintenance and relapse processes, the psychometric properties of scores on the ASI-3 have not yet been investigated for use among smokers. Therefore, the current study aimed to test the psychometric properties of the scores on the ASI-3 in a sample of cigarette smokers. Participants were treatment-seeking daily smokers who completed the ASI-3 at a precessation visit (Time 1, N = 464) and 3 months postcessation attempt (Time 2, n = 137). Confirmatory factor analyses results of the scores on ASI-3 at Time 1 and Time 2 revealed the hypothesized 3-factor model, including physical, social, and cognitive concerns. In addition, the ASI-3 factor scores evidenced factor stability, test-retest reliability, internal consistency, and convergent, and discriminant, and predictive validity. The present study provides evidence in support of the validity and reliability of scores on the ASI-3 as a measure of Anxiety Sensitivity among treatment-seeking cigarette smokers.

  • Polish Adaptation and Psychometric Validation of the Anxiety Sensitivity Index-III
    Journal of Individual Differences, 2014
    Co-Authors: Jarosław M. Michałowski, Paweł Holas, Michael J. Zvolensky
    Abstract:

    The present study sought to adapt and validate the psychometric properties of the Anxiety Sensitivity Index-III in Poland. The ASI-III consists of three subscales, each representing one of the three domains of fears of the negative consequences of Anxiety-related physical, cognitive, or social sensations. The study included a total of 116 panic disorder patients and 411 controls who did not show the presence of mental disorders. The results indicated that the Polish-language version of the ASI-III is characterized by high content validity, internal consistency, and stability over a period of 28 days. Moreover, its factor structure was largely equivalent to that found on the original ASI-III.

  • sixteen item Anxiety Sensitivity Index confirmatory factor analytic evidence internal consistency and construct validity in a young adult sample from the netherlands
    Assessment, 2007
    Co-Authors: Anka A Vujanovic, Peter J. Norton, Willem A Arrindell, Amit Bernstein, Michael J. Zvolensky
    Abstract:

    The present investigation examined the factor structure, internal consistency, and construct validity of the 16-item Anxiety Sensitivity Index (ASI; Reiss Peterson, Gursky, & McNally 1986) in a young adult sample (n = 420) from the Netherlands. Confirmatory factor analysis was used to comparatively evaluate two-factor, three-factor, and four-factor models of the Anxiety Sensitivity construct. Support was found for a hierarchical structure of Anxiety Sensitivity, with one global higher-order factor and four lower-order factors. Internal consistency for the global and lower-order factors of the 16-item ASI was adequate. Convergent and discriminant associations between the 16-item ASI and general mood and panic-specific variables were consistent with Anxiety Sensitivity theory. In addition, incremental validity of the Anxiety Sensitivity construct was established, relative to negative affectivity, for unexpected panic attacks and agoraphobic avoidance.

  • an expanded Anxiety Sensitivity Index evidence for a hierarchic structure in a clinical sample
    Journal of Anxiety Disorders, 1998
    Co-Authors: Steven Taylor, Brian J. Cox
    Abstract:

    Abstract Anxiety Sensitivity (AS) is the fear of Anxiety-related sensations. According to Reiss’s (e.g., Reiss, 1991 ) expectancy theory, AS amplifies fear and Anxiety reactions, and plays an important role in the etiology and maintenance of Anxiety disorders, particularly panic disorder. Recent evidence suggests that AS has a hierarchical structure, consisting of multiple lower order factors, loading on a single higher order factor. If each factor corresponds to a discrete mechanism (Cattell, 1978) , then the results suggest that AS arises from a hierarchic arrangement of mechanisms. A problem with previous studies is that they were based on the 16-item Anxiety Sensitivity Index, which may not contain enough items to reveal the type and number of lower order factors. Also, some of the original ASI items are too general to assess specific, lower order factors. Accordingly, we developed an expanded measure of AS—the ASI-R—which consists of 36 items with subscales assessing each of the major domains of AS suggested by previous studies. The ASI-R was completed by 155 psychiatric outpatients. Factor analyses indicated a four-factor hierarchical solution, consisting of four lower order factors, loading on a single higher factor. The lower order factors were: (1) fear of respiratory symptoms, (2) fear of publicly observable Anxiety reactions, (3) fear of cardiovascular symptoms, and (4) fear of cognitive dyscontrol. Each factor was correlated with measures of Anxiety and depression, and fear of cognitive dyscontrol was most highly correlated with depression, which is broadly consistent with previous research. At pretreatment, patients with panic disorder tended to scored highest on each of the factors, compared to patients with other Anxiety disorders and those with nonAnxiety disorders. These findings offer further evidence that Reiss’s expectancy theory would benefit from revision, to incorporate the notion of a hierarchic structure of AS.

  • Ethnoracial differences in Anxiety Sensitivity: examining the validity of competing Anxiety Sensitivity Index subscales.
    Journal of anxiety disorders, 2012
    Co-Authors: Lora Rose Hunter, Meghan E. Keough, Kiara R. Timpano, Norman B. Schmidt
    Abstract:

    Abstract Despite the increasing number of Americans who are considered to be a part of an ethnoracial minority group, there have been few investigations of the cross-cultural validity of measures of psychopathology. The limited existing literature suggests potential differences between African American (AA) and European American (EA) individuals with respect to the utility of self-report measures, including Anxiety Sensitivity. Physical, mental, and social domains of Anxiety Sensitivity are measured using subscales derived from a 3-factor model reported in EA samples despite evidence suggesting that Anxiety Sensitivity in AA samples is characterized by more distinct physical concerns. The current study compared the concurrent and predictive validity of the traditional Anxiety Sensitivity subscales representing 3 domains and a 4-subscale formulation based on predictions about the construct in AA samples. Comparisons of both AA ( N  = 41) and EA ( N  = 298) samples are included. Findings suggest some ethnoracial group differences in the concurrent and predictive validity of Anxiety Sensitivity subscales, specifically supporting the appropriateness and specificity of the 4-factor model of Anxiety Sensitivity in AA samples. Implications are discussed, including identification of sociocultural mechanisms that might influence psychometric properties of measures of Anxiety.

  • Structure of the Anxiety Sensitivity Index psychometrics and factor structure in a community sample
    Journal of anxiety disorders, 2002
    Co-Authors: Norman B. Schmidt, Thomas E. Joiner
    Abstract:

    Abstract Converging evidence suggests that Anxiety Sensitivity (i.e., threatening beliefs regarding autonomic arousal) is a risk factor for Anxiety pathology. Specification of premorbid risk factors requires exclusion of individuals with a history of spontaneous panic to ensure that Anxiety Sensitivity is not merely a consequence or concomitant of the experience of panic. However, the psychometrics and dimensional nature of Anxiety Sensitivity in such a sample is undetermined. The present study evaluated the factor structure of the Anxiety Sensitivity Index (ASI), a measure of Anxiety Sensitivity, in a community sample ( N =233) with no history of psychiatric illness or spontaneous panic. Exploratory factor analyses (EFA) suggested a two- or three-factor solution (I, Fear of Mental Catastrophe; II, Fear of Cardiopulmonary Sensations; III, Fear of Vasovagal Sensations). Confirmatory factor analyses (CFA) comparing alternative models indicated that a hierarchical two-factor solution (I, Fear of Mental Catastrophe; II, Fear of Cardiopulmonary Sensations) best accounted for the data. This model generalized well to a nonclinical college sample ( N =809).

  • the Anxiety Sensitivity Index item analysis and suggestions for refinement
    Journal of Personality Assessment, 2001
    Co-Authors: Mark A Blais, Norman B. Schmidt, Richard J. Mcnally, Michael W Otto, Bonnie G Zucker, Maurizio Fava, Mark H Pollack
    Abstract:

    Anxiety Sensitivity is the fear of Anxiety-related sensations, and is measured by the 16-item Anxiety Sensitivity Index (ASI; Reiss, Peterson, Gursky, & McNally, 1986). Despite the popularity and utility of the ASI in research, a number of studies have provided evidence for the inadequacy of several items, and item-to-scale correlations for the ASI have not been published. In this study, a converging set of analyses to evaluate the item adequacy and factor structure of the ASI was used. The results of these multiple analyses converged nicely suggesting that Items 1, 5, 7, 8, and 13 should be considered for removal from the instrument. The impact of removing these problematic items from the scale was explored through the reanalysis of data from 3 previously published studies that compared the original ASI with the new 11-item version (the ASI minus the 5 problematic items). The results of these analyses suggest that the 2 scales function comparably in many respects but that the new version may be a more pr...

  • Anxiety Sensitivity Index: normative data and its differentiation from trait Anxiety
    Behaviour research and therapy, 2001
    Co-Authors: Bonifacio Sandín, Paloma Chorot, Richard J. Mcnally
    Abstract:

    In the present study we report: (1) normative data on the Spanish version of the Anxiety Sensitivity Index (ASI); and (2) empirical evidence related to differentiation between the constructs of Anxiety Sensitivity and trait Anxiety. A sample of 390 university students (ranging in age from 18 to 34 years) completed the ASI and Spielberger's Trait Anxiety Scale (STAI-T). The means and standard deviations for the Spanish version of the ASI are similar to the ones reported by Peterson and Reiss (Anxiety Sensitivity Index Manual, 2nd edition. Worthington, OH: International Diagnostic Systems, 1992) for the English version. Factor analysis of the joint ASI and STAI-T items yielded two different factors; the STAI-T items load onto one factor (i.e., the trait Anxiety factor) and the ASI items load onto the other factor (i.e., the Anxiety Sensitivity factor). Findings provide empirical support for validation of the Spanish ASI and are consistent with a construct distinction between Anxiety Sensitivity and trait Anxiety.

  • Validation of the Spanish version of the Anxiety Sensitivity Index in a clinical sample
    Behaviour research and therapy, 1996
    Co-Authors: Bonifacio Sandín, Paloma Chorot, Richard J. Mcnally
    Abstract:

    In this study we validated the Spanish version of the Anxiety Sensitivity Index (ASI) in a sample of Anxiety disordered patients. The results revealed that: (1) ASI scores were higher for Anxiety disordered patients than for normal control subjects, and higher for patients with panic disorder (PD) than for patients with other Anxiety disorders (OAD). In contrast, there were no differences among the groups on the Cognitive-Somatic Anxiety Questionnaire (CSAQ). (2) Using discriminant analysis, we were able to differentiate PD patients from patients with OAD on the ASI, but not on the CSAQ. (3) Results supported a unidimensional factor-structure for the ASI. (4) Data provide cross-cultural evidence for construct validity and concurrent validity of the Spanish ASI, and provide further evidence for the usefulness of the concept of Anxiety Sensitivity.

  • Alexithymia and Anxiety Sensitivity in panic disorder and obsessive-compulsive disorder.
    The American journal of psychiatry, 1993
    Co-Authors: Sharon B. Zeitlin, Richard J. Mcnally
    Abstract:

    The authors compared scores on the Toronto Alexithymia Scale and the Anxiety Sensitivity Index of 27 patients with panic disorder and 31 patients with obsessive-compulsive disorder. Results suggest that patients with panic disorder constrict emotional experience, thereby reducing the likelihood of their experiencing physiological symptoms that accompany affect.
