A combined emotional Stroop and implicit memory (tachistoscopic identification) task with 3 types of words (panic-related, interpersonal threat, and neutral words) and 2 exposure conditions (subliminal, supraliminal) was administered to 35 patients with panic disorder and 35 age- and sex-matched controls. The patients showed Stroop interference for panic-related words both sub- and supraliminally and a similar but not equally robust effect on interpersonal threat words. On the tachistoscopic identification task, the patients identified more panic-related words than the controls did but showed no implicit memory bias effect. The patients' subliminal Stroop interference for panic-related words was found to correlate with trait anxiety and depression, although not with anxiety sensitivity.

The cognitive models of panic disorder with (PDA) or without (PD) agoraphobia are now widely recognised. These models propose that patients misinterpret external or internal cues in a catastrophic manner and as a result of these catastrophic cognitions the symptoms are maintained. There is now a large body of empirical evidence for this proposal and the aim of this paper is to systematically review the literature to evaluate whether the empirical evidence supports the contribution of catastrophic cognitions to PD and PDA. Empirical studies using different methodologies, such as interview, questionnaire, self-monitoring, and in vivo techniques are reviewed. The results indicate there is substantial empirical evidence in support of the central role of catastrophic cognition in cognitive models. Different methodologies provided convergent support for the importance of catastrophic cognitions in the maintenance of panic disorder and agoraphobia. Limitations in the interpretation of the existing research are highlighted and future research directions are proposed. 相似文献

Thirty patients with a diagnosis of panic disorder with agoraphobia and 30 normal controls were compared on explicit memory (cued recall) and implicit memory (word stem completion) for positive, neutral, social threat, and physical threat words. The panic patients showed an explicit memory bias, but no implicit memory bias, for physical threat words. The index of explicit memory bias for physical threat words was found to correlate with anxiety sensitivity and degree of agoraphobic fear and avoidance. The index of baseline bias for threat words on the word completion task, on the other hand, correlated with trait anxiety. Although there were no correlations between explicit and implicit memory bias for physical threat words, explicit memory bias for physical threat words correlated with explicit memory bias indexes for positive words and social threat words. The results are discussed in terms of the functional role of an explicit memory bias for physically threatening events in panic disorder. The negative results on implicit memory bias are discussed in relation to earlier studies, the use of different implicit memory tasks, and the role of baseline bias on implicit memory tasks. Finally, the hypothesis is suggested that explicit and implicit memory bias for emotional information may represent two different styles of information processing, which serve as vulnerability factors for different emotional disorders. 相似文献

Panic patients with agoraphobia were compared with normal controls on tasks of face recognition. The subjects were presented with 20 photos, and were required to make a judgement of the persons on the photos; shortly afterwards they were unexpectedly presented with a recognition task. In the first study, one task was to judge whether the persons on the photos were critical or accepting: unlike social phobics (Lundh and Ost, 1996b, Behaviour Research and Therapy, 34, 787-794), panic patients showed no bias for critical vs accepting faces on the recognition task. In a secondary study, the task was to judge whether the persons on the photos were 'safe' or 'unsafe', i.e. whether they could be relied on if the subject would need help in some situation. The results showed a recognition bias for safe vs neutral faces in panic patients. The index of recognition bias for safe faces correlated with avoidance of feared situations when accompanied by others, as measured by the Mobility Inventory. The possibility that memory bias in emotional disorders is a function of basic concern, or functional importance, rather than positive/negative valence is discussed. The results are also discussed in terms of degree of elaboration, exposure duration of the stimuli, and the generality of the findings. 相似文献

Although situational avoidance is viewed as the most disabling aspect of panic disorder, few studies have evaluated how dimensions of neurotic (i.e., neuroticism, behavioral inhibition) and extraverted (i.e., extraversion, behavioral activation) temperament may influence the presence and severity of agoraphobia. Using logistic regression and structural equation modeling, we examined the unique effects of extraverted temperament on situational avoidance in a sample of 274 outpatients with a diagnosis of panic disorder with and without agoraphobia. Results showed low extraverted temperament (i.e., introversion) to be associated with both the presence and the severity of situational avoidance. Findings are discussed in regard to conceptualizations of conditioned avoidance, activity levels, sociability, and positive emotions within the context of panic disorder with agoraphobia.

This study proposed and tested a theoretical factor structure for the Alcohol Expectancy Questionnaire (AEQ; S. A. Brown, M. S. Goldman, A. Inn, & L. R. Anderson [see record 1981-01217-001]). Factors were hypothesized to (a) reflect either positive or negative reinforcement, and (b) target either personal feelings or social contexts, resulting in 4 hypothesized factors (Social Enhancement, Social Coping, Personal Enhancement, Personal Coping). Participants were 180 male and 226 female undergraduates who completed the AEQ and additional self-report measures. Confirmatory factor analysis revealed that the hypothesized model fit the data. Post hoc adjustments further improved the model. Finally, a higher order factor model fit the data best. Factors correlated in hypothesized ways with other measures: (a) Only Personal Coping expectancies correlated with negative affect; (b) self-efficacy to resist drinking for emotional relief correlated highest with Personal Coping; and (c) self-efficacy to resist social pressure to drink correlated highest with Social Enhancement. Correlations with B. C. Leigh and A. W. Stacy's (see record 1993-35856-001) Drinking Expectancy Questionnaire indicated congruent and divergent validity.

Tested the validity of the distinction made in the Diagnostic and Statistical Manual of Mental Disorders (DSM-III) between the diagnoses of "panic disorder" and "agoraphobia with panic attacks" by examining the pattern of covariation between panic symptoms and agoraphobic fear in a group of individuals presenting with panic attacks as a prominent symptom. Ss were 17 patients (mean age 34.4 yrs) who had been diagnosed as having panic disorder and 56 patients (mean age 36.4 yrs) diagnosed as having agoraphobia with panic attacks, and who had completed at the time of diagnosis both the Fear Survey Schedule and the SCL-90-R. Analyses of the panic-related items and the agoraphobia-related items of these 2 inventories revealed that irrespective of diagnosis, the degree of panic was highly correlated with the degree of agoraphobic fear. Although panic patients tended to experience more severe panic and milder agoraphobic fear than agoraphobics, the groups overlapped with respect to both kinds of symptoms. Findings are discussed in terms of whether panic disorder and agoraphobia should be classified as qualitatively distinct conditions.

BACKGROUND: Imipramine has proven efficacy for panic disorder. This study assesses the net effectiveness of systematic, open imipramine treatment in a homogenous sample of panic disorder patients with agoraphobia. METHODS: One hundred and ten consecutive patients with DSM-III-R moderate to severe panic disorder with agoraphobia were treated with a fixed regimen of imipramine 2.25 mg/kg/day for 24 weeks. No instructions or encouragement for self-directed exposure to phobic situations or other coping strategies with panic or fear were given. Assessments were conducted at the end of the 2-week placebo run-in and at weeks 8, 16, and 24 of treatment. RESULTS: Overall, 53% had a marked and stable response. Most measures revealed that substantial improvement continued beyond week 8 of treatment. Treatment success was accompanied with significant improvements in anxiety sensitivity, dysphoric mood, and functional well-being. CONCLUSIONS: These results provide a clinically relevant reference with which to compare the effectiveness of alternative treatments in providing nearly complete symptom remission in patients with primary panic disorder with agoraphobia. 相似文献

This study examined premature termination from couples' group treatment for panic disorder with agoraphobia. Patients were classified as either treatment noncompleters or treatment completers. Comparisons of pretreatment self-report and clinician-rated measures of anxiety and depression indicated no differences between groups. On communication measures, however, partners of noncompleters rated themselves as less communicative about panic-related issues. Of noncompleters, the majority reported "getting to treatment sessions" as problematic and indicated dissatisfaction with the cognitive-behavioral treatment approach. Results are discussed in terms of these issues and their impact on the treatment of these patients. (PsycINFO Database Record (c) 2010 APA, all rights reserved) 相似文献

In recent years, cognitive–behavioural interventions have proven to be effective in the treatment of Panic Disorder with Agoraphobia (PDA). However, there is controversy concerning treatment efficacy of PDA for patients with a comorbid diagnosis of Personality Disorder (PD). This study evaluates the impact of a PD on PDA treatment response. 81 patients suffering from PDA were recruited from a cognitive–behavioural group treatment program. Diagnoses on Axis I (N?=?81) and Axis II (N?=?36) were made at treatment onset according to Diagnostic and Statistical Manual of Mental Disorders-III-Revised (DSM-III-R) criteria. Validated questionnaires were used to assess agoraphobia at treatment onset, following treatment, and at the 3 mo follow-up. All patients improved markedly from pretest to posttest and at the 3 mo follow-up. Grouping of patients according to the presence or absence of a personality disorder revealed significant differences between the groups on pre- and posttreatment scores on agoraphobia. Results also reveal that patients with a personality disorder improve more slowly than patients without a personality disorder. (PsycINFO Database Record (c) 2010 APA, all rights reserved) 相似文献

Enhanced conditionability has been proposed as a crucial factor in the etiology and maintenance of panic disorder (PD). To test this assumption, the authors of the current study examined the acquisition and extinction of conditioned responses to aversive stimuli in PD. Thirty-nine PD patients and 33 healthy control participants took part in a differential aversive conditioning experiment. A highly annoying but not painful electrical stimulus served as the unconditioned stimulus (US), and two neutral pictures were used as either the paired conditioned stimulus (CS+) or the unpaired conditioned stimulus (CS-). Results indicate that PD patients do not show larger conditioned responses during acquisition than control participants. However, in contrast to control participants, PD patients exhibited larger skin conductance responses to CS+ stimuli during extinction and maintained a more negative evaluation of them, as indicated by valence ratings obtained several times throughout the experiment. This suggests that PD patients show enhanced conditionability with respect to extinction. (PsycINFO Database Record (c) 2010 APA, all rights reserved) 相似文献

This study compared 96 women and 58 men suffering from panic disorder with agoraphobia. Participants completed questionnaires assessing various clinical features associated with panic disorder with agoraphobia (PDA), general adjustment, and drug/alcohol use. Results showed that PDA is a more severe condition in women. Women reported more severe agoraphobic avoidance when facing situations or places alone, more catastrophic thoughts, more body sensations, and higher scores on the Fear Survey Schedule. Also, women more often had a comorbid social phobia or posttraumatic stress disorder. The lower agoraphobic avoidance of men was associated with their alcohol use. However, there were no differences between genders in other dimensions, including depression, situational and trait anxiety, stressful life events, social self-esteem, marital adjustment, and drug use. 相似文献

Granulocytes, monocytes, and T- and B-lymphocytes were separated from 28 blood samples collected from 5 bone marrow transplant (BMT) recipients. About 40% of granulocyte, monocyte, and B-lymphocyte samples were CMV DNA-positive by polymerase chain reaction in recipients with cytomegalovirus (CMV) infection. CMV DNA was rarely detected in separated T-lymphocytes. Within each of the simultaneously separated paired samples, there were several with single positive cell subtypes. Monocytes, granulocytes, and B-lymphocytes were the single positive samples in some instances. Thus, it is important to have all of the different cell subtypes present in samples for detection of CMV DNA in peripheral blood. We also studied the appearance of CMV DNA in plasma and peripheral blood leukocytes (PBLs) from 351 blood samples collected from 30 BMT recipients during a follow-up period of at least 3 months after BMT. All cell subtypes were represented in the PBL samples. In the 13 recipients who developed symptoms possibly associated with CMV infection or CMV disease, a correlation with the detection of CMV DNA in < or = 2 x 10(5) PBLs was found. In PBLs from 11 of the 13 BMT recipients, CMV DNA was detected before the onset of symptoms. CMV DNA was not detected in < or = 2 x 10(5) PBLs from recipients without CMV infection. The virus load in PBLs decreased during ganciclovir treatment. Nine of the 13 recipients displayed PCR-positive plasma samples, and CMV DNA was detected frequently after the onset of symptoms. 相似文献

The theoretical parameters of the biosocial model of personality that underlie the item domain of the Tridimensional Personality Questionnaire (C. R. Cloninger; see records 75:1507 and 17186) were assessed with confirmatory factor analysis (CFA). Using a large sample of community-based adults (n?=?360) and undergraduate students(n?=?233), CFA was used to examine the relationship between the items and their correspondent subscales, as well as the relationship between the subscales and their correspondent personality domain. Results indicated that the items composing the 4 subscales for each of the 3 personality domains matched the underlying theoretical model and that the 12 subscales that comprise the 3 personality domains decomposed into 3 dimensions theoretically consistent with the biosocial model of personality.

In a randomized controlled trial, eye movement desensitization and reprocessing (EMDR) for panic disorder with agoraphobia (PDA) was compared with both waiting list and credible attention-placebo control groups. EMDR was significantly better than waiting list for some outcome measure, (questionnaire, diary, and interview measures of severity of anxiety, panic disorder, and agoraphobia) but not for others (panic attack frequency and anxious cognitions). However, low power and, for panic frequency, floor effects may account for these negative results. Differences between EMDR and the attention placebo control condition were not statistically significant on any measure, and, in this case, the effect sizes were generally small (η?=?.00–.06), suggesting the poor results for EMDR were not due to lack of power. Because there are established effective treatments such as cognitive–behavior therapy for PDA, these data, unless contradicted by future research, indicate EMDR should not be the first-line treatment for this disorder.

This study examined the effect of having a safe person present on artificially induced anxiety following a biological challenge among panic-disordered patients. Anxiety symptoms were induced using a 5.5% CO?-inhalation procedure. Panic patients underwent the inhalation procedure either in the presence or absence of their safe person. Nonanxious controls underwent the procedure without a safe person. Panic patients exposed to CO? without their safe person present reported greater distress, a greater number of catastrophic cognitions, and a greater level of physiological arousal than did panic patients exposed with their safe person. The latter group did not differ from controls on most measures at postexposure. The attenuation of self-reported anxiety and catastrophic cognitions is consistent with the safety-signal theory and the cognitive model of panic, respectively. The results, however, are inconsistent with a biological model of panic. (PsycINFO Database Record (c) 2010 APA, all rights reserved) 相似文献

The study objectives were to determine comorbidity rates for various subtypes of specific phobia (SP) in a sample of patients with the principal diagnosis of panic disorder with agoraphobia (PDA) and to examine the possible etiologic relatedness of these SP subtypes to PDA. Ninety consecutive day clinic patients with PDA were administered the Structured Clinical Interview for DSM-III-R (SCID) modified for DSM-IV. The overall comorbidity rate for SP was 65.6%. The most frequent subtypes of SP were situational phobia and dental phobia, followed by natural environment phobia, phobia of funerals, cemeteries, dead bodies, and other death-related phenomena and objects (referred to as death-related phobia), and blood-injection-injury phobia. Except for death-related phobia, other subtypes of SP clearly tended to precede the onset of PDA, often by many years. The smallest difference between the age of onset for PDA and particular subtypes of SP (temporal distance) was found for death-related phobia, whereas the temporal difference was longer for situational phobia, hospital phobia, and blood-injection-injury phobia. The frequency and temporal distance data suggest that death-related phobia may constitute a risk factor for developing PDA or that it is a prodrome of PDA, whereas situational phobia, hospital phobia, and blood-injection-injury phobia appear to predispose to PDA to a lesser degree. Of the three broadly conceived groups of SP, mutilation phobias (which include death-related phobia, hospital phobia, blood-injection-injury phobia, and dental phobia) appear most etiologically relevant for PDA, with the group of situational phobias (which also includes the natural environment subtype of SP) being less relevant, and animal phobias showing a negligible etiologic relatedness to PDA. 相似文献

Psychometric properties of the Beck Anxiety Inventory (BAI) (Beck and Steer, 1990) were investigated in a sample of 82 patients suffering from panic disorder with agoraphobia. Before and after brief treatment, patients completed a battery of questionnaires and, for 2-week periods, kept a daily panic diary in which they recorded panic attacks, fear of panic, and average anxiety. The BAI demonstrated excellent internal consistency and good test-retest reliability over a 5-week interval. A partial multitrait, multimethod correlation matrix provided evidence of convergent validity with other measures of anxiety and of divergent validity vis á vis measures of depression. Factor analyses of pretest scores and residual gain scores used to address criticism that the BAI is excessively panic-centric yielded mixed results. In one analysis, the BAI was loaded with multimethod measures of panic and anxiety and, in the other, with questionnaire methods of assessing anxiety and depression. However, the BAI was clearly distinguished from measures of fear of fear, a central construct in panic disorder, and agoraphobic avoidance. Finally, the BAI proved sensitive to change with treatment, yielding effect sizes for improvement comparable to those of other anxiety measures. 相似文献

Five competing models specifying the factor structure underlying the Wechsler Memory Scale--Third Edition (D. Wechsler, 1997b) primary subtest scores were evaluated in a sample of patients with intractable temporal lobe epilepsy (N=254). Models specifying separate immediate and delayed constructs resulted in inadmissible parameter estimates and model specification error. There were negligible goodness-of-fit differences between a 3-factor model of working memory, auditory memory, and visual memory and a nested--more parsimonious--2-factor model of working memory and general memory. The results suggest that specifying a separate visual memory factor provides little advantage for this sample--an unexpected finding in a population with lateralized dysfunction, for which one might have predicted separate auditory and visual memory dimensions.
