Long-term outcome of panic disorder with agoraphobia treated by exposure.

BACKGROUND: There is a paucity of long-term outcome studies of panic disorder that exceed a 2-year follow-up. The aim of the study was to evaluate the long-term follow-up of patients with panic disorder with agoraphobia treated according to a standardized protocol. METHODS: A consecutive series of 200 patients satisfying the DSM-IV criteria for panic disorder with agoraphobia was treated in an out-patient clinic with behavioural methods based on exposure homework. One hundred and thirty-six patients became panic free after 12 sessions of psychotherapy and 132 were available for follow-up. A 2- to 14-year (median = 8 years) follow-up was performed. Survival analysis was employed to characterize the clinical course of patients. RESULTS: Thirty-one of the 132 patients (23%) had a relapse of panic disorder at some time during follow-up. The estimated cumulative percentage of patients remaining in remission was 93.1 after 2 years, 82.4 after 5 years, 78.8 after 7 years and 62.1 after 10 years. Such probabilities increased with younger age, and in the absence of a personality disorder, of high pre-treatment levels of depressed mood, of residual agoraphobic avoidance after exposure, and of concurrent use of benzodiazepines and antidepressant drugs. CONCLUSIONS: The findings suggest that exposure treatment can provide lasting relief to the majority of patients with panic disorder and agoraphobia. Disappearance of residual and subclinical agoraphobic avoidance, and not simply of panic attacks, should be the aim of exposure therapy.

The relationship between agoraphobia symptoms and panic disorder in a non-clinical sample of adolescents.

BACKGROUND: The purpose of this study was to evaluate the clinical correlates of agoraphobic fear and avoidance and panic disorder in a non-clinical sample of adolescents. METHOD: In a sample of 2365 high school students, combined data from a questionnaire and a structured clinical interview were used to classify subjects with agoraphobic fear and avoidance. Panic symptoms, major depression, childhood separation anxiety disorder, anxiety sensitivity and negative affectivity were also assessed. RESULTS: Fifteen subjects met study criteria for agoraphobic fear and avoidance in the past year. Only three (20%) of those with agoraphobia symptoms reported histories of panic attacks and there was no overlap between those with agoraphobic fear and avoidance and the 12 subjects who met DSM-III-R criteria for panic disorder. However, subjects with agoraphobia symptoms and those with panic disorder reported similar levels of anxiety sensitivity and negative affectivity. Childhood separation anxiety disorder was more common among those with agoraphobic fear and avoidance compared to those without. CONCLUSION: Agoraphobic avoidance is rare in non-clinical samples of adolescents and usually not associated with panic attacks. However, adolescents with agoraphobia symptoms and those with panic disorder have similar clinical correlates consistent with a panic/agoraphobia spectrum model.

[Are eight-year olds already suffering from panic disorder? Investigation of prevalence with focus on panic disorder and agoraphobia].

A representative sample of 826 eight-year-old second-graders in Dresden was examined in a two-stage procedure to ascertain the 6-month prevalence of DSM-IV anxiety disorders. Particular care was taken to assess panic disorder. The eight-year-olds had already been interviewed personally in a screening session and in 230 children an individual diagnostic examination with a structured diagnostic interview was carried out. The total prevalence of anxiety disorder was 9.5%. No case of either panic disorder or agoraphobia was found. For the diagnosis of agoraphobia the DSM-IV diagnostic criterion was lacking in which situations typical to agoraphobia are feared or avoided because escape would be difficult or it would be difficult to reach help. Eight-year-olds do not forge this cognitive link. In agoraphobic situations 2.5% of the children (almost exclusively, girls) suffer from a specific phobia. The prevalence of anxiety disorders is markedly higher among girls than in boys.

Relationship between perfectionism, personality disorders and agoraphobia in patients with panic disorder.

OBJECTIVE: In earlier reports, we found that perfectionism might be involved in the development and/or maintenance of agoraphobia in panic disorder. The present report extends this work by examining the relationship between perfectionism and comorbidity with personality disorders in panic disorder patients with agoraphobia (PDA) and those without agoraphobia (PD). METHOD: We examined comorbidity of personality disorders by Structured Clinical Interview for DSM-III-R Personality Disorders (SCID-II) and assessed perfectionism using multidimensional perfectionism scale in 56 PDA and 42 PD patients. RESULTS: The PDA group met criteria for at least one personality disorder significantly more often than the PD group. With stepwise regression analyses, avoidant and obsessive-compulsive personality disorders emerged as significant indicators of perfectionism in patients with panic disorder. CONCLUSION: These findings suggest that perfectionism in panic disorder patients may be more common in those with comorbid personality disorders, and may be an important target for preventive and therapeutic efforts.

Agoraphobia: nurse therapist-facilitated self-help manual.

BACKGROUND: Agoraphobia is a common and disabling mental health disorder. Substantial evidence supports the use of cognitive behaviour therapy (CBT), in particular the intervention termed exposure therapy, as the treatment of choice. However, although the evidence base for cognitive-behaviour therapy is extensive, the service delivery evidence base is poor, and alternative ways of delivering therapy are required if mental health services are to achieve standards set out by the National Service Framework in the United Kingdom. AIM: The study had two aims: (1) to develop a self-help manual, which could be facilitated by a nurse trained in CBT, for clients suffering from agoraphobia and (2) to pilot the self-help manual and evaluate its effectiveness. METHOD: The self-help manual was piloted with experienced nurses trained in CBT on three clinical sites for 10 weekly sessions of 30 minutes duration. A range of clinical outcome measures was administered by an independent assessor before and after treatment and at 1-month follow-up. RESULTS: A total of 18 clients completed treatment and results showed improvement on all clinical measures; improvement was maintained at 1-month follow-up. Importantly, 89% of clients were clinically significantly improved at post-treatment assessment. Clients were satisfied with their treatment and the self-help manual, and therapists found facilitated self-help an acceptable way to deliver treatment. CONCLUSION: Nurses can deliver effective support to patients using a self-help manual for agoraphobia. Although the results are promising, further work is required with larger numbers, longer follow-up and economic evaluation under controlled conditions. The work could also be adapted to different psychological conditions. Variation in the amount of specialist educational training is necessary to determine how many nurses are needed to support patients using self-help.

["Agoraphobia--place anxiety/place fear--place-related vertigo". The classical description of place anxiety by Carl Westphal and Emil Cordes and its significance for the history of the concept and current discussion of anxiety disorders].

We discuss the history of "agoraphobia" and related descriptions as the "Platzangst" from M. Benedikt and the artile of E. Cordes, who used the same title "agoraphobia" as Westphals original paper. It is remarkable that Westphal and Cordes recognized the psychological character of the phenomenon, whereas Benedikt in 1870 suspected a neuroophthalmological origin for his "Platzschwindel". Regarding the details of these first three descriptions one can show that the primary authorities set up a discussion, which is still going on: The relation between agoraphobia, dizziness, fear and panic is until now object of many controversies, as shown in the final chapter.

[Quantitative assessment of brain morphology with CT in agoraphobia].

This CT study was designed to assess brain morphology in agoraphobia. 21 patients and 21 normal control subjects matched in age and sex were investigated. Frontal and parietooccipital cortex, temporal cortex, lateral ventricles and third ventricle were evaluated by qualitative assessment on a 3-point scale (normal, questionable, abnormal). Patients showed significant bilateral enlargement of prefrontal cortical cerebrospinal fluid (CSF) spaces (p < .05). The rating "abnormal" was given to none (0%) of the normal controls, but to 6 (28.6%) of the patients in the left hemisphere, and to 4 patients (19%) in the right hemisphere, respectively. No qualitative differences were seen in the temporal cortex, lateral ventricles and third ventricle. These findings support the hypothesis that alterations in brain morphology are involved in the etiology of agoraphobia. The lack of a correlation between CSF enlargement and duration of illness suggests that prefrontal CSF enlargement is a neurobiological vulnerability marker in agoraphobia.

Occurrence of imagery and its link with early memories in agoraphobia.

Recent cognitive models suggest that mental imagery can help us understand the maintenance of anxiety disorders (e.g., de Silva, 1986; Hackmann, Surawy, & Clark, 1998). However, imagery is relatively unexplored within agoraphobia. Such images are also thought to be useful in uncovering memories that occurred around the onset of a disorder (Hackmann, Clark, & McManus, 2000). A total of 20 patients with agoraphobia and 20 matched controls took part in this investigation. Participants described any recurrent images they experienced in agoraphobic situations, and also any associated memories. All patients with agoraphobia (but no control participants) reported having distinct recurrent images in "agoraphobic situations". Most images involved several sensory modalities and in the majority of cases appeared to be linked with unpleasant memories of events experienced many years previously. While these exploratory findings require replication, potential treatment implications are discussed.

Healthcare utilization following cognitive-behavioral treatment for panic disorder with agoraphobia.

The aim of this study was to examine the overall changes in healthcare services utilization after providing an empirically supported cognitive-behavioral treatment for panic disorder with agoraphobia. Data on healthcare utilization were collected for a total of 84 adults meeting DSM-IV criteria. Participants were completers of a cognitive-behavioral treatment for panic disorder with agoraphobia. Data on utilization of healthcare services and medication were obtained from semi-structured interviews from baseline to 1-year after treatment. Results of the Friedman non-parametric analysis reveal a significant decrease in overall and mental health-related costs following treatment. This study shows a significant reduction in healthcare costs following cognitive behavior therapy for panic disorder with agoraphobia. More studies are needed to examine the potential long-term cost-offset effect of empirically supported treatments for panic disorder.

Panic and agoraphobia in a virtual world.

Virtual reality (VR) offers a great new perspective on what it can offer an individual. These new approaches can give an individual the immersion and cognitive guidance that they need to help overcome his or her disorder. VR differs from the traditional displays in computer graphics as these various displays are integrated to give the user a sense of presence or immersion in the virtual world. To more effectively treat panic and agoraphobic patients using VR, it is necessary to determine the physiological responses of nonphobics when placed in the virtual panic and agoraphobia environments. This study exposed nonphobic participants to virtual panic and agoraphobia worlds with a program entitled "Virtual Medicine." Individuals without a diagnosis of panic and agoraphobia, as confirmed by intake and self-report questionnaires, were exposed to four different VR environments (elevator, supermarket, town square, and beach). During these VR experiences, physiology was measured by noninvasive sensors (peripheral skin temperature, heart rate, heart rate variability, respiration, and skin conductance). These measurements were compared to baseline physiology, which was recorded for five min prior to the VR exposure. These levels of physiological arousal will be useful in comparing against the phobic responses during virtual exposure. It will be useful to explore differences between immersion, physiological responses, and self-report responses in nonphobics versus phobics.

Panic disorder and agoraphobia in consecutively referred children and adolescents.

OBJECTIVE: This report examines the clinical features and correlates of juvenile panic disorder in referred children and adolescents to test specific hypotheses about its relationship with adult panic disorder. METHOD: The sample consisted of consecutively referred children and adolescents (N = 472) comprehensively evaluated with structured diagnostic interviews, cognitive tests, and psychosocial assessments. RESULTS: Panic disorder was identified in 6% and agoraphobia in 15% of psychiatrically referred children and adolescents. Children meeting criteria for panic disorder also frequently met criteria for agoraphobia. The latter disorder was more prevalent and had an earlier age at onset than panic disorder. Children with panic disorder and those with agoraphobia had similar correlates with frequent comorbidity with other anxiety and mood disorders. A high level of comorbidity with disruptive disorders was also identified. CONCLUSIONS: These results support the hypothesis of continuity between the juvenile and the adult form of panic disorder. However, the high level of comorbidity with disruptive behavior disorders also suggests developmentally specific discontinuities between juveniles and adults with panic disorder.

Relationship between agoraphobia and field dependence.

In recent years agoraphobia has been viewed by clinicians as etiologically distinct from other phobic disorders, with conflicts over the developmentally early issue of separation and individuation (self-other differentiation) playing a central role. In an effort to adduce quantitative evidence for this clinical observation, three groups of phobic patients (totaling 166 outpatients in all) were distinguished on the basis of their symptomatology (agoraphobia, simple phobias, and mixed phobias) and were individually administered the Group Embedded Figures Test as a measure of field dependence, a cognitive style dimension that according to Witkin is, at least in part, a manifestation of self-other differentiation. A one-way analysis of variance, performed separately for men and women for differences among the three phobic groups on field dependence, showed significance (rho less than .05) for the females, with the famale agoraphobic being more field dependent than the female simple phobic groups, but not for the males. Implications for the understanding of agoraphobia are discussed.

Remission and relapse in subjects with panic disorder and panic with agoraphobia: a prospective short-interval naturalistic follow-up.

This article reports on the course of uncomplicated panic disorder and panic with agoraphobia on 309 patients participating in the Harvard/Brown Anxiety Research Project, a prospective longitudinal study of patients with DSM-III-R-defined anxiety disorders. At 1 year, there was a .39 probability of full remission for uncomplicated panic disorder and a .17 probability of full remission for panic disorder with agoraphobia Similar differences in time to remission for these syndromes were still found when criteria for remission were made less stringent. However, even requiring less improvement for remission left a large percentage of subjects in an episode, and for those that remitted, relapse occurred quickly, indicating a chronic and recurrent course of illness. This is the first longitudinal, prospective, naturalistic study on a large cohort of subjects with anxiety disorders to have regular, structured, short-interval follow-up. Our results are consistent with the view that panic disorder has a chronic course with high rates of relapse after remission and longer episodes when agoraphobia is a part of the constellation of symptoms.

Distinguishing panic disorder and agoraphobia from social phobia.

An attempt was made to differentially diagnose panic disorder with agoraphobia from social phobia on the basis of self-reported phobic situations, panic attack symptomatology, and feared outcomes. Sixty-nine patients with panic disorder (with and without agoraphobia) were compared with 69 patients with social phobia. Subjects completed a modified self-report version of the panic and phobia sections from the Composite International Diagnostic Interview to assess phobic situations, panic symptomatology, and feared outcomes. The two groups were distinguishable on all three measures. A diagnostic algorithm was developed that predicted the primary diagnosis allocated by a clinician for subjects who meet DSM-III-R criteria for panic disorder (with or without agoraphobia) rather than social phobia on the basis of self-reported phobic avoidance, panic symptomatology, and feared outcomes.

Social anxiety and agoraphobia in the eating disorders: associations with core beliefs.

The eating disorders have a high comorbidity with anxiety disorders, but it is not clear what cognitions underpin those anxiety symptoms. The present study investigated whether social anxiety and agoraphobia in eating-disordered individuals are associated with different types of unconditional core beliefs. The participants were 70 women meeting DSM-IV criteria for an eating disorder. The short version of Young's Schema Questionnaire (YSQ-S) was used as a measure of core beliefs, while the Social Phobia and Anxiety Inventory was used as a measure of levels of social anxiety and agoraphobia. Eating-disordered individuals reporting high levels of comorbid social anxiety had higher abandoment and emotional inhibition core beliefs. In contrast, patients with high levels of agoraphobia had higher vulnerability to harm beliefs. The findings highlight the importance of identifying and addressing core beliefs in subgroups of eating-disordered individuals presenting with comorbid anxiety. Implications for future research are discussed, including the need for longitudinal studies to elaborate on the specificity of the cognition-anxiety link in the eating disorders.

The function of agoraphobia in the marital relationship.

A secondary analysis was carried out of data from a previous experiment on the treatment of agoraphobia. This analysis shows that, contrary to some reports in the literature, agoraphobics do have more problems in the relationship with their partner than the average members of the normal population. The analysis also shows that individual-oriented behavioural treatment of the agoraphobia significantly improves the marital relationship. The findings contradict the theory that agoraphobia serves a function in the relationship with the partner.

Guttman scaling in agoraphobia: cross-cultural replication and prediction of treatment response patterns.

The Fear and Avoidance Scales (FAS) is an 11-item questionnaire consisting of two subscales that measure features of agoraphobia and claustrophobia and that were demonstrated to be valid Guttman scales in a British clinical population. The purposes of the study reported here were to replicate the scale characteristics in the United States and to determine if improvement during treatment would follow the sequence predicted by the hierarchy implied in the scales. The FAS was given to 25 female agoraphobics before and after behavioural treatment. A principal components analysis replicated the agoraphobia and claustrophobia factors established in the British sample. Scalogram analyses showed that the Claustrophobia subscale of the FAS was a valid Guttman scale in the US sample whereas the Agoraphobia subscale yielded a high coefficient of reproducibility but a low coefficient of scalability. Treatment reduced the patients' fears and avoidances in the predicted sequence since for both scales the hierarchy of items remained unchanged following treatment.

Interpersonal problems among patients suffering from panic disorder with agoraphobia before and after treatment.

The aim of this study was to examine interpersonal problems among panic disorder with agoraphobia patients before and after treatment. Patients (N = 46) suffering from panic disorder with moderate or severe agoraphobia and considering agoraphobia as their main problem were randomly assigned to receive either cognitive therapy or guided mastery therapy in a six-week in-patient group programme. The Inventory of Interpersonal Problems (IIP) and various symptom measures were administered at pretreatment and at one-year follow-up. Two IIP subscales were derived from factor analysis of the present data: affiliation problems and power problems. The overall pattern of results supported a state model of interpersonal problems. At pre-treatment, the scores on the affiliation problems subscale were clearly related to non-specific state characteristics, that is, to depression and general anxiety. From pre-treatment to follow-up, levels of interpersonal problems decreased significantly. Pre-treatment depression was a powerful predictor of change in interpersonal problems from pre-treatment to one-year follow-up. On the other hand, interpersonal problems at pre-treatment failed to predict the change in levels on various symptom scales.
