Anxiety sensitivity and nonclinical panic attacks

The present study examined anxiety sensitivity in relation to trait anxiety and the occurrence of nonclinical panic attacks in 265 subjects. Fifty percent of high anxiety sensitivity subjects reported panic attacks (both cued and spontaneous) in the past year. In addition, almost 42% of subjects with high anxiety sensitivity but no history of panic reported a high level of trait anxiety concerning physical danger. The results suggest that anxiety sensitivity is frequently not independent of other forms of anxiety.     

Agoraphobia with and without current panic attacks

MMPI and SCL-90-R profiles of agoraphobics with and without current panic attacks are presented. Agoraphobics with current panic attacks were more elevated on Psychopathic Deviate (4), Psychasthenia (7), and Social Introversion (0) scales of the MMPI. On the SCL-90-R agoraphobics with current panic attacks had higher scores on Interpersonal Sensitivity, Anxiety, Phobic Anxiety, and Total/90.     

Self-monitoring of panic attacks and retrospective estimates of panic: discordant findings.

An event sampling method was used to study the frequency of panic attacks during treatment of agoraphobics. Results revealed a much lower incidence of panic attacks in agoraphobics according to self-monitoring than was expected on account of their retrospective estimation. When more stringent criteria for panic attacks are applied, retrospective overestimation becomes even more apparent. The implication of this finding for the classification of panic disorder patients is discussed.     

Dyspneic-fear and catastrophic cognitions in hyperventilatory panic attacks

The tenability of cognitive explanations of the experience of fear during panic attacks (viz. Ley's misattribution-of-symptoms hypothesis and Beck's and Clark's catastrophic-misinterpretation-of-symptoms hypotheses) is seriously questioned by findings from three independent lines of research: (a) Wolpe and Rowan's observation that catastrophic cognitions follow fear, (b) Rachman, Levitt and Lopatka's reports of panic attacks without fearful cognitions, and (c) reports of panic attacks during sleep occurring predominately during non-dreaming stages of sleep. Recognition of these findings led Ley to reject his misattribution-of-symptoms hypothesis in favor of an innate emotional-respiratory-response explanation. The revised hyperventilation theory now maintains that fear experienced during a hyperventilatory panic attack is caused by severe dyspnea in the context of little or no perceived control over the causes of the dyspnea (i.e. dyspneic-fear). Cognitions during panic attacks are discussed in terms of the cognitive deficit that results from the cerebral hypoxia produced by hyperventilation. Implications for theory and treatment are discussed.     

Feared consequences of panic attacks in panic disorder: A qualitative and quantitative analysis

Cognitions are hypothesized to play a central role in panic disorder (PD). Previous studies have used questionnaires to assess cognitive content, focusing on prototypical cognitions associated with PD; however, few studies have qualitatively examined cognitions associated with the feared consequences of panic attacks. The purpose of this study was to conduct a qualitative and quantitative analysis of feared consequences of panic attacks. The initial, qualitative analysis resulted in the development of 32 categories of feared consequences. The categories were derived from participant responses to a standardized, semi-structured question (n?=?207). Five expert-derived categories were then utilized to quantitatively examine the relationship between cognitions and indicators of PD severity. Cognitions did not predict PD severity; however, correlational analyses indicated some predictive validity to the expert-derived categories. The qualitative analysis identified additional areas of patient-reported concern not included in previous research that may be important in the assessment and treatment of PD.

An animal model for situational panic attacks

An animal model for human panic attacks is presented, based on the abortive avoidance activity displayed by rats undergoing flooding. A shortcoming of the model is discussed. Methods for suppressing such abortive avoidance activity (‘panic’) are reviewed, including pharmacological and behavioural methods.     

Peritraumatic and persistent panic attacks in acute stress disorder

This study examined the prevalence of peritraumatic and persistent panic symptoms following trauma. Survivors of civilian trauma (n=30) with either acute stress disorder (ASD) or no acute stress disorder (non-ASD) were administered the Panic Module of the Structured Clinical Interview for DSM-IV (SCID). Participants also completed the Impact of Event Scale, Acute Stress Disorder Scale, Beck Depression Inventory, Beck Anxiety Inventory, and the Anxiety Sensitivity Index. Panic attacks were experienced by 77% of participants during their trauma, and 47% reported recurrent panic attacks post-trauma. ASD participants demonstrated more panic symptoms during and after their trauma than non-ASD participants. Posttraumatic panic was most strongly associated with anxiety sensitivity. These findings are discussed in terms of cognitive factors that may mediate posttrauma panic and treatment implications for managing posttraumatic anxiety.There is increasing evidence that panic attacks play a role in psychopathological response to trauma. A significant proportion of people with panic disorder report a history of trauma (). Moreover, two-thirds of trauma survivors report panic attacks within the previous 2 weeks (). There is also evidence that people with posttraumatic stress disorder (PTSD) display elevated levels of anxiety sensitivity (). Recent attention has focused on acute panic reactions because of proposals that panic during trauma may condition trauma-related cues to subsequent panic (). There is evidence that panic attacks occur in 53-90% of trauma survivors during the traumatic experience (). Further, people with acute stress disorder (ASD) are more likely to report peritraumatic panic attacks than non-ASD individuals. ASD is a useful framework in which to investigate the role of panic in posttraumatic stress because ASD describes acute responses to trauma that are strongly predictive of chronic PTSD ().This study investigated the relationship between peritraumatic panic and ongoing panic attacks following trauma. Specifically, we indexed panic attacks during trauma and subsequent to trauma in trauma survivors with and without ASD. We also indexed the extent to which distorted interpretations about somatic sensations may be associated with panic attacks following trauma. We considered that the strong evidence that maladaptive appraisals of somatic sensations mediate panic () is directly relevant to posttraumatic panic. We hypothesized that ASD participants would report more peritraumatic and persistent panic than non-ASD participants, and that this panic would be associated with dysfunctional interpretations about somatic stimuli.     

Anxiety sensitivity and panic attacks in a nonclinical population

In the present study, we administered the Anxiety Sensitivity Index (ASI) and a modified version of the Panic Attack Questionnaire (PAQ) to 425 college students to determine whether high anxiety sensitivity ('fear of fear') occurs in the absence of a history of unpredictable ('spontaneous') panic attacks, or whether such attacks are a necessary precursor to high anxiety sensitivity. Based on their ASI scores, subjects were assigned to either the high, medium, or low anxiety sensitivity groups. High anxiety sensitivity subjects more frequently reported both a personal and family history of panic than did subjects in the other groups. Nevertheless, two-thirds of the high anxiety sensitivity subjects had never experienced an unpredictable panic attack. This suggests that the fear of anxiety can be acquired in ways other than through personal experience with panic.     

Predicting who benefits from psychoeducation and self help for panic attacks

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.     

Multiple channel exposure therapy for women with PTSD and comorbid panic attacks

Multiple channel exposure therapy (M-CET; Falsetti & Resnick, 2000) was developed to treat posttraumatic stress disorder (PTSD) with comorbid panic attacks and can be administered in a group format. In addition to being a cost-effective way to provide treatment, group treatment for those with PTSD has been proposed as potentially very beneficial for addressing feelings of shame related to the traumatic event as well as social isolation in general (Foy et al., 2000). Previous studies of M-CET indicate that it may be effective for the treatment of PTSD with comorbid panic attacks (Falsetti et al., 2001, 2003, 2005). The authors examine the relationship of PTSD and panic symptoms pre- and posttreatment and present 6-month follow-up data on the long-term effectiveness of M-CET.
