We investigated cardiac perception in panic disorder with both self-report and objective measures. In Study 1, 120 patients with panic disorder, 86 infrequent panickers, and 38 patients with other anxiety disorders reported greater cardiac and gastrointestinal awareness than 62 normal control subjects. Subjects with panic attacks reported greater cardiac awareness, but not gastrointestinal awareness, than those with other anxiety disorders. Studies 2 and 3 included a test of heart rate perception in which subjects silently counted their heart-beats without taking their pulse. In Study 2, 65 panic disorder patients showed better performance than 50 infrequent panickers, 27 patients with simple phobias, and 46 normal control subjects. No group differences were found in ability to estimate time intervals. In Study 3, 13 patients with panic disorder and 15 with generalized anxiety disorder showed better heart rate perception than 16 depressed patients.  相似文献

This study examined the point prevalence of smoking in patients with anxiety disorders who do not have comorbid alcohol or substance abuse or dependence (ASAD). In a retrospective chart review, the smoking status of 581 patients with anxiety disorders was assessed. Patients, ages 18–65, were seeking treatment for anxiety disorders at an outpatient clinic that specialized in anxiety and related disorders. All participants were interviewed using the Anxiety Disorders Interview Schedule—IV, during which their smoking status was assessed. The prevalence of smoking across all anxiety disorders was 14.8%, which is much lower than found in the general population (23.3%; CDC, 2002) and even lower than previous estimates in individuals with comorbid anxiety and ASAD. Individuals with panic disorder and generalized anxiety disorder had the highest prevalence of smoking, although these rates were still considerably lower than those found in previous studies of smokers with anxiety disorders. Reasons for lower prevalence estimates are discussed.  相似文献

This study aimed to enhance knowledge of the construct validity and diagnostic efficiency of the depression- and anxiety-related scales of the MCMI-III (Millon, 1994). The MCMI-III, various concurrent depression and anxiety measures, and an Axis I structured diagnostic interview were administered in a total sample of 696 outpatients with depressive disorders, anxiety disorders, or both. Sound construct validity was found for the Dysthymia and Major Depression clinical syndrome scales and the Avoidant and Depressive personality disorder scales. The validity of the Anxiety scale was poor, showing moderate convergence with panic and worry-related anxiety measures, but problems discriminating from depression. Operating characteristics for discriminating depressed patients from anxious patients were fair for the Major Depression scale, but poor for the Anxiety and Dysthymia scales.  相似文献

The tendency to perceive anxious states as aversive and harmful is hypothesized to confer vulnerability to the development of anxiety disorders. The most commonly used measure of anxiety sensitivity, the Anxiety Sensitivity Index [ASI; Reiss, S., Peterson, R.A., Gursky, D.M., & McNally R.J. (1986). Anxiety sensitivity, anxiety frequency, and the prediction of fearfulness. Behavior Research and Therapy, 24, 1-8], is composed of multiple lower-order factors, assessing fear of physical symptoms, fear of publicly observable anxious symptoms, and fear of cognitive dyscontrol. This study examined the convergent validity of the lower-order anxiety sensitivity dimensions in DSM-IV diagnosed anxiety disorders. Participants with primary diagnoses of panic disorder with agoraphobia, social phobia, and generalized anxiety disorder (GAD) completed the ASI and measures of anxiety and depression severity. Support was found for the convergent validity of all ASI dimensions in reference to thematically related anxiety disorders and in the identification of patients presenting with and without secondary major depressive disorder (MDD). The ASI-fear of cognitive dyscontrol dimension displayed strong and nonredundant associations with GAD, dimensional depression scores, and secondary diagnoses of MDD. The conceptual implications of the shared importance of fear of cognitive dyscontrol in GAD and MDD are discussed.  相似文献

Previous research has indicated that reports of panic attacks are associated with a different set of symptoms to reports of generalized anxiety. The present two studies attempted to extend these findings to specific (situational) fears. In Study 1, 55 subjects with panic disorder were compared on their symptom profile during their panic attacks to 65 subjects with other anxiety disorders [simple phobia, social phobia and obsessive-compulsive disorder (OCD)] during response to their feared cue. The results indicated that, compared to subjects with other anxiety disorders, subjects with panic disorder were more likely to report parasthesias, dizziness, faintness, unreality, dyspnea, fear of dying and fear of going crazy/losing control. In Study 2, 90 subjects meeting diagnostic criteria for both panic disorder and another anxiety disorder (simple phobia, social phobia or OCD) were compared on the symptoms experienced during their unexpected panic attacks and their situationally-triggered fears respectively. Combining the symptoms found in Study 1 to differ between the groups into a linear combination, there was a significant interaction found between the type of fear reaction (panic attack vs cued fear response) and symptom group. Taken together, these findings suggest that reports of unexpected panic attacks associated with panic disorder are characterized by a different symptom profile to reports of specific fear reactions that are part of a phobic disorder or OCD.  相似文献

Although clinical observations suggest that health-related anxiety is present, to some extent, in a number of anxiety disorders, this relationship has not been examined empirically. The present study therefore utilized the Short Health Anxiety Inventory (SHAI) to elucidate the structure of such symptoms among patients with anxiety disorders and to empirically investigate the presence of health anxiety in various anxiety disorders. Confirmatory factor analysis yielded equivalent support for either a 2-factor or 3-factor model of the SHAI's latent structure. The measure demonstrated good reliability, convergent validity, and discriminant validity. Comparison of SHAI scores across groups of patients with various anxiety disorders revealed elevated levels of health anxiety among patients with hypochondriasis and panic disorder relative to those with other anxiety disorders. Receiver operating characteristic analyses supported the utility of the SHAI as a diagnostic tool for screening patients with hypochondriasis utilizing empirically derived cut scores. Findings are discussed in terms of cognitive-behavioral models of anxiety disorders.  相似文献

Anxiety sensitivity (AS) is a construct that denotes an individual difference in fear of anxiety. Most research into the AS construct has focused on its association with panic attacks, panic disorder and several other psychiatric disorders. There has been growing interest recently in AS as an important factor in the maintenance and exacerbation of morbidity associated with some disabling chronic health conditions (e.g. gastrointestinal dysfunction, asthma, vestibular dysfunction and chronic pain). The purposes of this paper are (a) to provide a brief overview of the theoretical framework within which the AS and chronic health condition literature can be synthesized, (b) to review the existing literature regarding AS and chronic health conditions and (c) to offer recommendations for assessment and treatment. Theoretically and practically relevant directions for future investigation are provided throughout the review.  相似文献

Contrary to the contention of Cox, Cohen, Direnfeld and Swinson (1996, Behaviour Research and Therapy, 34, 949–954) that the Beck Anxiety Inventory (BAI; Beck & Steer, 1993, Manual for the Beck Anxiety Inventory) measures primarily symptoms associated with panic attacks rather than anxiety in general, we propose that the higher level of anxiety found in patients with panic disorders not only is not an artifact of the BAI's symptom content, but patients with panic disorders truly have more anxiety than patients with other types of anxiety disorders. Furthermore, the BAI contains symptoms present in other anxiety disorders, besides panic disorder, and specifically includes 11 symptoms of generalized anxiety disorder (GAD). The BAI and revised Hamilton Anxiety Rating Scale (HARS-R; Riskind, Beck, Brown & Steer, 1987, Journal of Nervous and Mental Disease, 175, 474–479) scores of 274 (69%) outpatients with panic disorders and 123 (31%) outpatients with GAD were found to differentiate these two diagnostic groups equally and significantly. The panic disorder outpatients had higher scores on both the BAI and the HARS-R than did the GAD patients. Thus, Cox et al.'s (1996) speculation about the BAI's yielding spuriously high levels of anxiety in patients with panic disorders revives an important issue relevant to the relation of panic disorder to GAD.  相似文献

The Body Vigilance Scale (BVS) is a measure developed to assess one’s conscious attendance to internal cues. The present report investigated the structure, correlates, and predictive utility of the BVS in nonclinical (N = 442) and anxiety (N = 135) disorder samples. The findings of Study 1 suggest that the BVS is 1-dimensional in a nonclinical sample, and Study 2 replicated the factor structure of the BVS in an anxiety disorder sample. Correlations between the BVS and related (i.e., anxiety sensitivity) and unrelated (i.e., social anxiety) variables were consistent with predictions in both studies. Study 2 also showed that body vigilance is primarily elevated in patients with panic disorder relative to other anxiety disorders. Relative elevations in body vigilance were also observed for patients with hypochondriasis and generalized anxiety disorder. The BVS also demonstrated a specific association with medical utilization and health-related safety-seeking behaviors after controlling for related variables in nonclinical and anxiety disorder samples. The implications of our findings for the nature and measurement of body vigilance as a predictor of health concerns in anxiety disorders are considered.  相似文献

Psychiatric Comorbidity and Functional Status in Adult Patients with Asthma   总被引:1,自引:0,他引:1  
The goals of this study were to characterize the frequency of psychiatric disorders among patients with asthma, and to compare differences in functional status among asthma patients with and without comorbid depression and anxiety disorders. Fifty patients with confirmed asthma were administered the Diagnostic Interview Schedule for DSM-III-R and completed the Medical Outcomes Study Short Form-36 Health Survey. Patients with asthma had a higher lifetime prevalence of major depression, panic disorder, and agoraphobia, but a lower prevalence of social phobia, compared to lifetime prevalence rates for psychiatric disorders in a national probability sample. Participants with comorbid asthma and major depression had poorer physical and mental health functioning and health perception than did asthma patients without major depression. The results suggest that certain psychiatric disorders are common among patients with asthma and that depression is associated with significantly increased functional morbidity. These findings underscore the need for the appropriate detection and treatment of these comorbid conditions.  相似文献

Research estimating the comorbidity of asthma and anxiety disorders has produced highly disparate findings and little consensus. This study is a meta-analytic review of data from 15 independent studies of the co-occurrence of adult asthma and anxiety disorders and was conducted to provide more precise comorbidity estimates. Aggregating across studies, the average prevalence of any anxiety disorder among adults with asthma was 34%, indicating a strong relationship between the two conditions in general. More specifically, the prevalence of panic attacks (25%), panic disorder (12%), agoraphobia (12%), and generalized anxiety disorder (9%) were considerably higher among adults with asthma than in the general population. However, additional analyses yielded prevalence estimates for specific phobia (10%), social phobia (7%) and posttraumatic stress disorder (6%) comparable to or lower than rates observed in the population at large. Attention to psychiatric symptoms should be a crucial component of asthma management, as anxiety disorders appear to be highly prevalent among persons with asthma and may be associated with increased asthma morbidity.

The symptom complex of panic disorder and generalized anxiety disorder suggests an etiological role for hyperventilation. The present study investigates the overlap between DSM-III-R panic disorder, panic disorder with agoraphobia and generalized anxiety disorder with hyperventilation syndrome (HVS). The anxiety disorder diagnoses were based on a structured interview, and HVS syndrome (HVS). The anxiety disorder diagnoses were based on a structured interview, and HVS determined by the so-called hyperventilation provocation test (a brief period of voluntary hyperventilation with recognition of symptoms). The overlap rates with HVS were: 48% for panic disorder, 83% for panic disorder with agoraphobia and 82% for generalized anxiety disorder. However, a pilot study on transcutaneous monitoring of carbon dioxide tension leads us to question the validity of the voluntary hyperventilation method that we used to determine HVS-status. It is unclear whether hyperventilation plays an important role in panic and general anxiety, as our overlap findings suggest. For patients who recognize the symptoms induced by voluntary hyperventilation, the hyperventilation provocation procedure provides a therapeutic means of exposure to feared bodily sensations.  相似文献

Persistent postural-perceptual dizziness (PPPD; previously termed “chronic subjective dizziness”) is a frequently observed disorder in patients who present with dizziness to audiology; ear, nose, and throat; or neurology clinics. The primary symptoms are persistent nonvertiginous dizziness, and hypersensitivity to motion and visual stimuli. These occur either in the absence of any active neuro-otologic illness or, where an episodic vestibular disorder exists, symptoms cannot be fully explained by the disorder alone. Diagnosis is necessarily multidisciplinary and proceeds by identification of primary symptoms and exclusion of other neurological or active medical disorders requiring treatment. Psychological processes are implicated in the development and maintenance of PPPD, with similarities to cognitive models of health anxiety and panic disorder, and there is evidence that cognitive-behavioral therapy is an effective treatment. A cognitive-behavioral model of PPPD is presented along with a case example. It is suggested that dizziness becomes persistent when it is processed as a threat, and that it is maintained by (a) unhelpful appraisals, (b) avoidance and safety behaviors, and (c) attentional strategies including selective attention to body sensations associated with dizziness. Once PPPD is identified techniques for its effective treatment fall within the skills mix of qualified cognitive-behavioral therapists or vestibular clinical scientists who have received additional training in cognitive and behavioral treatment.  相似文献

Electrodermal lability in anxiety disorders   总被引:1,自引:0,他引:1  
Twenty-eight anxiety patients, aged below 50 years, were diagnosed according to DSM-III-R criteria (panic disorder with and without agoraphobia, generalised anxiety disorder, and anxiety disorder not otherwise specified). The patients were characterised by high levels of state and trait anxiety and neuroticism, compared with the controls. However, there were no differences between patients and controls in electrodermal habituation rate, non-specific activity, or skin resistance level. When the patients were divided into electrodermally labile and stable subjects, significant differences were found between patients and controls in both electrodermal activity and Eysenck's personality dimensions. The labile patients were more introverted and attained higher psychoticism scores than either the stable patients or controls. Duration of anxiety symptoms removed the difference found in extroversion, but not in any other variable. The results are discussed in relation to the utility of electrodermal measurements in validation of diagnostic entities. It is concluded, that from the psychophysiological point of view, anxiety disorders may be examined within a dimensional framework.  相似文献

Self-help and psychoeducation have been identified as effective methods for delivering treatment, yet not everyone benefits from these brief interventions. Therefore it is clinically and economically useful to identify who is likely to require more intensive assistance. This paper develops a prognostic scale which predicts who will recover from panic attacks and who will require more assistance. Method: Random regression models were used to evaluate the relationship between predictive variables, baseline severity, and the rate of improvement in 117 people with DSMIV panic attacks who participated in a trial of a psycho-educational booklet, a self-help workbook, and brief group CBT over a 9-month period. ROC analysis was used to choose cut-off points on a scale made up of significant predictors. Results: Panic disorder and agoraphobia symptom measures were predicted by baseline social anxiety, and general mental health. There was no significant effect on the outcome for baseline depression or anxiety sensitivity. While general mental health (SF12 Mental Component scores) was predicted by the age at first panic attack, neuroticism, panic disorder and/or agoraphobia symptoms and a positive screen for alcohol use disorders. A prognostic scale based on simple additive scoring was equivalent to standard scores and significantly better than chance at predicting who would recover and who required face-to-face therapy. Conclusions: The prognostic scale may be used to guide the choice of psychoeducation, self-help or face-to-face therapy as the first step in stepped care.  相似文献

Abstract

Previous research has demonstrated that patients with generalised anxiety disorder, phobias, and obsessive-compulsive disorder show an attentional bias towards threat cues related to their respective disorders. Two studies are presented that used a modified Stroop colour naming task to assess attentional bias in subjects with panic attacks. In Study 1, 24 panic disorder patients and 24 normal controls were presented three cards containing threat words related to physical harm, separation, or social embarrassment. Colour naming times were compared between these cards and control cards containing matched non-threat words. Reaction time differences in the two groups were in opposite directions, patients tending to be slower in colour naming threat words, and controls, faster. In Study 2, 18 non-clinical panickers and 18 controls were presented cards containing physical threat words, neutral control words, or colour words, respectively. Panickers showed greater interference than controls in colour naming threat words but not in colour naming colour words. The results are consistent with an attentional bias for threat-related material in subjects with panic attacks. Implications for psychophysiological models of 'spontaneous' panic attacks are discussed.  相似文献

A growing literature suggests robust associations between dimensions of emotion regulation and emotional disorder psychopathology. However, limited research has investigated associations of emotion regulation dimensions across several emotional disorders (transdiagnostic associations), or the incremental validity of emotion regulation versus the higher-order construct of neuroticism. The current study used exploratory structural equation modeling and a large clinical sample (N = 1,138) to: (a) develop a multidimensional emotion regulation measurement model, (b) evaluate the differential associations between latent emotion regulation dimensions and five latent emotional disorder symptom dimensions (social anxiety, depression, agoraphobia/panic, obsessions/compulsions, generalized worry), and (c) determine the incremental contribution of emotion regulation in predicting symptom dimensions beyond neuroticism. The best-fitting measurement model of emotion regulation included four dimensions: Problematic Responses, Poor Recognition/Clarity, Negative Thinking, and Emotional Inhibition/Suppression. Although many zero-order associations between the four latent emotion regulation dimensions and five latent symptom dimensions were significant, few associations remained significant in a structural regression model that included neuroticism. Specifically, Negative Thinking and Problematic Responses incrementally predicted depression symptoms, while Emotional Inhibition/Suppression predicted both social anxiety and depression symptoms. Associations between neuroticism and the emotional disorder dimensions were similar regardless of whether the emotion regulation dimensions were held constant. These results suggest that self-reported emotion regulation dimensions are associated with the severity and expression of a range of emotional disorder symptoms, but that some emotion regulation dimensions have limited incremental validity after accounting for general emotional reactivity. Studies of emotion regulation should assess neuroticism as a key covariate.  相似文献

The procedural validity of the Composite International Diagnostic Interview - short form (CIDISF) administered via an Internet web-page was examined and compared with an in-person interview (Structured Clinical Interview for DSM-IV Axis I Disorders, research version; SCID) for 7 DSM-IV mental disorders: major depression, generalized anxiety, specific phobia, social phobia, agoraphobia, panic attack and obsessive-compulsive disorder. The 53 participants completed a computerized interview (CIDI-SF) via a web page 2 days before the scheduled in-person interview (SCID). The agreement between CIDI-SF and SCID was generally low (Cohens Kappa <0.40). However, if the panic disorder module from the long version of CIDI is used instead, the Kappa is fair (K = 0.48) with an agreement of 75%. Practical applications and future directions are discussed.  相似文献

Patients with non-fear panic disorder (NFPD) meet DSM-III-R criteria for panic disorder, but do not report subjective fear or anxiety. Although apparently common in medical settings, this controversial group is in need of further diagnostic validation. This study assessed family history of panic disorder in patients with chest pain and normal coronary arteries (CP/NCA) and either NFPD, panic disorder with fear, or no panic. It was hypothesized that the two panic disorder groups would have similar, elevated rates of panic disorder in their first-degree relatives, compared to patients without panic. The results support the hypothesis; about 17% of the first-degree relatives of both NFPD and panic disorder patients were diagnosable with panic disorder according to proband interviews, whereas only 4.6% of the first-degree relatives of patients without panic were so diagnosable. These results support the diagnostic validity of NFPD in CP/NCA patients, because such patients had a family history of panic disorder similar to patients with a more classical panic disorder presentation. The lack of fear symptoms and behavior in NFPD may cause panic disorder to be overlooked as a potential cause of somatic symptoms in patients with no medical explanation for their condition.  相似文献

This article describes a reanalysis of seven studies on heart beat perception (HBP) in panic disorder. The pooled sample had 709 participants from eight diagnostic categories. Accurate HBP was uncommon, but more prevalent among panic disorder patients than among healthy controls, depressed patients, patients with palpitations and individuals with infrequent panic attacks. No differences were found between panic disorder patients and patients with other anxiety disorders. Accurate perceivers had higher anxiety sensitivity scores than inaccurate perceivers. The data remain inconclusive as to whether perceived heart rate is correlated with anxiety in inaccurate perceivers. Physical exercise, distraction, variations in instructions and treatment each influenced HBP. However, the influence was different than previously thought. Finally, it is suggested that HBP may be understood in terms of schema-guided information processing.  相似文献
