Taxonicity of anxiety sensitivity: a multi-national analysis.

Taxometric coherent cut kinetic analyses were used to test the latent structure of anxiety sensitivity in samples from North America (Canada and United States of America), France, Mexico, Spain, and The Netherlands (total n = 2741). Anxiety sensitivity was indexed by the 36-item Anxiety Sensitivity Index--Revised (ASI-R; [J. Anxiety Disord. 12(5) (1998) 463]). Four manifest indicators of anxiety sensitivity were constructed using the ASI-R: fear of cardiovascular symptoms, fear of respiratory symptoms, fear of publicly observable anxiety reactions, and fear of mental incapacitation. Results from MAXCOV-HITMAX, internal consistency tests, analyses of simulated Monte Carlo data, and a MAMBAC external consistency test indicated that the latent structure of anxiety sensitivity was taxonic in each of the samples. The estimated base rate of the anxiety sensitivity taxon differed slightly between nations, ranging from 11.5 to 21.5%. In general, the four ASI-R based manifest indicators showed high levels of validity. Results are discussed in relation to the conceptual understanding of anxiety sensitivity, with specific emphasis on theoretical refinement of the construct.

Avoidance-oriented coping as a predictor of panic-related distress: a test using biological challenge.

The present experimental psychopathology study sought to investigate the extent to which pre-experimental levels of avoidance-oriented coping predict anxious and fearful responding during acute physical stress, relative to other theoretically relevant variables. Participants included 80 individuals with no known history of psychological or physical health problems. Dependent measures include self-reported anxiety, DSM-IV panic symptoms, and physiological indices of heart rate and skin conductance. Consistent with our hypotheses, the tendency to engage in avoidance-oriented coping predicted increased physical panic symptoms and self-reported anxiety elicited by biological challenge, relative to specific anxiety sensitivity (AS) dimensions. These findings are discussed in terms of how specific types of coping are associated with prototypical indices of panic distress, with implications for forwarding future work on emotional regulation in panic disorder.

Anxiety sensitivity in six countries.

In the present study, the Anxiety Sensitivity Index-Revised (ASI-R; ) was administered to a large sample of persons (n=2786) from different cultures represented in six different countries: Canada, France, Mexico, The Netherlands, Spain, and the United States. We sought to (a) determine the factor structure and internal consistency of the ASI-R and (b) examine the correlations of the measure with psychiatric symptoms and personality dimensions in a single European non-English speaking country (The Netherlands). Partially consistent with the original hypothesis, the underlying structure of the anxiety sensitivity construct was generally similar across countries, tapping fear about the negative consequences of anxiety-related physical and social-cognitive sensations. Lower-order factors were moderately to strongly correlated with one another and showed good internal consistency. The observed lower-order ASI-R factors correlated with established psychiatric symptoms and with the personality trait of neuroticism. Partial correlations indicated that both factors are useful in accounting for variance in symptom measures. We discuss the results of this investigation in relation to the cross-cultural assessment of the anxiety sensitivity construct.

Contemporary behavioral activation treatments for depression: procedures, principles, and progress.

In the past decade, there has been renewed interest in the feasibility and efficacy of purely behavioral treatments for clinical depression. Emphasizing the functional aspects of depressive and nondepressive behavior, these treatments focus on the concept of behavioral activation, which guides implementation of procedures aimed at increasing patient activity and access to reinforcement. Although researchers have provided positive preliminary support for behavioral activation-based interventions, many fundamental issues concerning strategies, principles, and change processes involved in behavioral activation have yet to be addressed. In this paper, we compare and contrast contemporary behavioral activation interventions, explore strategies and process of change issues, clarify the basic behavioral principles underlying activation strategies, and outline questions that need to be addressed to improve outcomes and better understand the potential significance of behavioral activation as it pertains to the future of behavior therapy for depression.

The effects of anxious responding on mental arithmetic and lexical decision task performance.

Anxiety-related responding and skill deficits historically are associated with performance-based problems such as mathematics anxiety, yet the relative contribution of these variables to substandard performance remains poorly understood. Utilizing a 7% carbon dioxide (CO2) gas to induce anxiety, the present study examined the impact of anxious responding on two performance tasks, mental arithmetic and lexical decision. Independent variables included math anxiety group, gender, and gas condition. Dependent variables included task performance and physiological and self-report indices of anxiety. A total of 64 university undergraduate students participated. Physiological and verbal-report measures of anxiety supported the utility of 7% carbon dioxide-enriched air as an anxiety-inducing stimulus. Behavioral disruption on performance tasks, however, did not differ as a function of carbon dioxide inhalation. Performance did differ as a function of math anxiety. High math anxious individuals generally exhibited higher error rates on mathematical tasks, particularly on tasks designed to measure advanced math skill and those requiring working memory resources. These findings are discussed with reference to processing efficiency theory, discordance among anxiety response systems, and the intricacies associated with skill measurement.

Heart-focused anxiety and chest pain in postangiography medical patients.

The present cross-sectional study sought to examine the extent to which heart-focused anxiety is associated with the co-occurrence of coronary artery disease (CAD) and a history of regular smoking in a sample of 148 postangiography patients from a cardiology unit. Individuals with CAD who regularly smoked demonstrated significantly greater heart-focused attention, but no greater degree of avoidance and fear of heart-focused sensations, than did nonsmoking persons with CAD and smokers without CAD. We also found evidence that heart-focused attention and fear incrementally predicted (above and beyond demographic variables and body mass index) intensity of average chest pain. Overall, this study provides some of the first empirical evidence that the occurrence of regular smoking and CAD is associated with specific dimensions of health anxiety. We discuss these findings in relation to models of panic pathology and anxious responding to bodily sensations.

The relations of anxiety sensitivity, experiential avoidance, and alexithymic coping to young adults' motivations for drinking.

The authors examined whether motivations for drinking alcohol are associated with the anxiety-related dispositional tendencies of anxiety sensitivity, experiential avoidance, and alexithymic coping. The authors administered the Anxiety Sensitivity Index, Experiential Avoidance Scale, 20-item Toronto Alexithymia Scale, Revised Drinking Motives Questionnaire, and a demographics questionnaire to 182 university drinkers. In multiple regressions, the dispositional factors significantly predicted the risky drinking motives of coping, enhancement, and conformity. Coping and enhancement motives were significantly predicted by experiential avoidance. Conformity motives were significantly and independently predicted by anxiety sensitivity and alexithymia. The process of experiential avoidance mediated the bivariate correlation between anxiety sensitivity and coping-motivated drinking to a greater extent than did the process of alexithymic coping. The authors discuss the observed relations in regard to the psychological functions of drinking behavior that may portend the development of heavy drinking and alcohol problems in dispositionally vulnerable individuals. They also review implications for refinements of behavior therapy for problem drinkers.

The effects of acceptance versus control contexts on avoidance of panic-related symptoms.

The present study compared the effects of creating an acceptance versus a control treatment context on the avoidance of aversive interoceptive stimulation. Sixty high anxiety sensitive females were exposed to two 10-min periods of 10% carbon dioxide enriched air, an anxiogenic stimulus. Before each inhalation period, participants underwent a training procedure aimed at encouraging them either to mindfully observe (acceptance context) or to control symptoms via diaphragmatic breathing (control context). A third group was given no particular training or instructions. We hypothesized that an acceptance rather than control context would be more useful in the reduction of anxious avoidance. Compared to control context and no-instruction participants, acceptance context participants were less avoidant behaviorally and reported less intense fear and cognitive symptoms and fewer catastrophic thoughts during the CO(2) inhalations. We discuss the implications of our findings for an acceptance-focused vs. control-focused context when conducting clinical interventions for panic and other anxiety disorders.
