With the advent of DSM-III-R, the diagnostic criteria for generalized anxiety disorder (GAD) shifted in emphasis from the autonomic arousal to the cognitive component of the disorder, namely worry. The Penn State Worry Questionnaire was developed to assess the trait of worry and has proven to be a reliable and valid measure in a series of studies largely(More)
Although the State-Trait Anxiety Inventory (STAI) is a popular measure of anxiety, some previous research suggests that the trait scale may assess depression, as well as anxiety. The factor structure of the trait items was initially examined using factor analytic procedures. Confirmatory factor analytic methods suggested that a hierarchical solution best(More)
To explore the role of perfectionism across anxiety disorders, 175 patients with either panic disorder (PD), obsessive compulsive disorder (OCD), social phobia, or specific phobia, as well as 49 nonclinical volunteers, completed two measures [Frost, R. O., Marten, P., Lahart, C., & Rosenblate, R., (1990). The dimensions of perfectionism. Cognitive Therapy(More)
BACKGROUND The Social Interaction Anxiety Scale and Social Phobia Scale are companion measures for assessing symptoms of social anxiety and social phobia. The scales have good reliability and validity across several samples, however, exploratory and confirmatory factor analyses have yielded solutions comprising substantially different item content and(More)
Anxiety disorder patients (n = 198; under criteria of the Diagnostic and Statistical Manual of Mental Disorders; rev. 3rd ed.; American Psychiatric Association, 1987) and nonanxious control subjects (n = 25) underwent challenges of 90 s of voluntary hyperventilation and 15 min of 5.5% carbon dioxide in air. Panic disorder subjects showed a greater(More)
The impact and course of additional diagnoses was examined in 126 patients undergoing cognitive-behavioral treatment for panic disorder. With the Anxiety Disorders Interview Schedule--Revised, a high comorbidity rate (51%) was observed at pretreatment. Pretreatment comorbidity was not predictive of premature termination, nor did it have a substantial impact(More)
Intolerance of uncertainty (IU) - a dispositional characteristic resulting from negative beliefs about uncertainty and its implications - may be an important construct in anxiety disorders and depression. Despite the potential importance of IU, clinical data on the construct remains relatively scant and focused on generalized anxiety disorder and(More)
This study investigated the psychometric properties of the Social Phobia Inventory [SPIN; Connor, K. M., Davidson, J. R. T., Churchill, L. E., Sherwood, A., Foa, E., Wesler, R.H., 2000. Psychometric properties of the Social Phobia Inventory (SPIN). British Journal of Psychiatry, 176, 379-386], a measure of severity in social phobia (social anxiety(More)
Coupling between EEG delta and beta oscillations is enhanced among anxious and healthy individuals during anticipatory anxiety. EEG coupling patterns associated with psychotherapy have not yet been quantified in socially anxious individuals. In this study, we used a double baseline, repeated measures design, in which 25 adults with a principal diagnosis of(More)
The purpose of this study was to test the theory put forth by Zvolensky et al. [Clin. Psychol. Sci. Pract. 10 (2003) 29] that smoking is specifically associated with panic disorder (PD) and not more generally associated with other anxiety disorders. Smoking behaviors were examined across three anxiety disorders: panic disorder with or without agoraphobia,(More)
