Agoraphobia

Individuals with agoraphobia are fearful and anxious about two or more of the following situations: using public transportation; being in open spaces; being in enclosed places; standing in line or being in a crowd; or being outside of the home alone in other situations. The individual fears these situations because of thoughts that escape might be difficult or help might not be available in the event of developing panic-like symptoms or other incapacitating or embarrassing symptoms. These situations almost always induce fear or anxiety and are often avoided or require the presence of a companion.

00:00:15[She nervously plays with her scarf as she breathes anxiously] 

00:00:25OFF CAMERA Hello Mrs. Weidre. Are you ok? Do you want some water or something? 

00:00:30MRS. WEIDRE I’m ok. I’m fine. 

00:00:35OFF CAMERA I understand you wanted to see me today. 

00:00:40[She breathes anxiously] 

00:00:40MRS. WEIDRE I just really needed to sit and talk. 

00:00:40OFF CAMERA Well, tell me what’s wrong, what are you feeling? 

00:00:50MRS. WEIDRE I’m just so… so unsure. I’m tired of being stuck in my house. I don’t like it. 

00:01:00OFF CAMERA Stuck in your house? Do you have difficultly leaving your house? 

00:01:05MRS. WEIDRE Yes. All the time. 

00:01:05OFF CAMERA When do you go out? 

00:01:10MRS. WEIDRE …maybe, once or twice. 

00:01:15OFF CAMERA A day? 

00:01:15[She clutches her hands to her chest] 

00:01:15MRS. WEIDRE A week. Tuesdays and Saturdays. 

00:01:20OFF CAMERA Why Tuesday and Saturday? 

00:01:30MRS. WEIDRE Because when my husband gets home, he can go with me. 

00:01:35OFF CAMERA What do you do when you go out? 

00:01:40MRS. WEIDRE I take walks. 

00:01:40OFF CAMERA Where do you walk? 

00:01:40MRS. WEIDRE I only go to the end of the block, and then I cross the street, and turn around, and I go back around the cul-de-sac. I’ll do that three times. [Losing breathe] No more, then I have to go back inside… I also go in my backyard. That’s usually okay. 

00:02:15OFF CAMERA On the walks, why do you have to go back after three times? What happens? 

00:02:20MRS. WEIDRE [She nervously looks around] I just can’t go any further. 

00:02:25OFF CAMERA Is this a physical problem, knees or something? 

00:02:30[She plays with her scarf] 

00:02:30MRS. WEIDRE No. No. Well… maybe. I just can’t breathe if I’m out any longer. 

00:02:40OFF CAMERA Oh, breathing? 

00:02:40MRS. WEIDRE Yeah. 

00:02:40OFF CAMERA What do you feel? 

00:02:45MRS. WEIDRE [Her voice quivering] I’m just so frightened. Really, really scared. You don’t realize what it took for me to get here today. I really had to. I willed it. I closed my eyes and my husband turned the radio up all the way as he drove. And then he lead me into the building. 

00:03:20OFF CAMERA Is there something that triggers this, anything in particular? 

00:03:30MRS. WEIDRE I don’t like people. Maybe that’s it. I mean I can tolerate them. Ethan, the little boy next door, I’ll bake things for him and say hello. Sometimes, sometimes I watch him when his parents are gone. I mean I can be around people. Maybe that’s not that’s not what I meant. 

00:04:00OFF CAMERA Ok, can you walk me through what happens when you do leave the house? 

00:04:05MRS. WEIDRE I get shortness of breathe, everything, the world just seems to close in on me, and everything gets feels really tight, the air in my body, my chest. I get dizzy. I don’t know what’s wrong… I could be sick. What is this? 

00:04:30OFF CAMERA There can be many different causes for this. What is it that frightens you? 

00:04:40MRS. WEIDRE [She’s short of breathe] Death. I’m afraid to die. 

00:04:45OFF CAMERA You’re afraid you might die? 

00:04:50MRS. WEIDRE Yes. Among other things but that’s what pops into my head. 

00:04:55OFF CAMERA Is there other stuff? 

00:05:00[sil.] 

00:05:05MRS. WEIDRE Cars go to fast. And there’s murders and rapes that I see on the news. And flashfloods. I just think its close, its safer to stay close to home. 

00:05:15OFF CAMERA How long have you had this fear? 

00:05:20MRS. WEIDRE I don’t really know. 

00:05:20OFF CAMERA Do you know when it all started? 

00:05:25MRS. WEIDRE I’m not sure. 

00:05:30OFF CAMERA Do you know what started it? 

00:05:30MRS. WEIDRE No. 

00:05:35OFF CAMERA When was the last time you really ventured out for any length of time? 

00:05:40MRS. WEIDRE Fifteen years. 

00:05:45[She nervously shifts in her chair] 

00:05:45OFF CAMERA That long. Is this the farthest you’ve been in fifteen years? What happened fifteen years ago? 

00:06:00MRS. WEIDRE I don’t really know. 

00:06:05OFF CAMERA There is nothing that happened to you personally that could have made you afraid of dying? 

00:06:10MRS. WEIDRE I always was. My mother died the year before that. But it happened little by little. First it was planes. And then I couldn’t drive on the freeway, then I couldn’t drive at all, then errands, then it was going out… and soon… here I am. 

00:06:40OFF CAMERA It must have taken you extraordinary courage to come here today. What finally brought you to see me? 

00:06:50MRS. WEIDRE My grandson was born. But I couldn’t go and see him. I still haven’t seen him. My daughter gave birth last week and she’s not going to bring him to see me for several months and I don’t want to wait that long. 

00:07:10OFF CAMERA You miss out. 

00:07:15MRS. WEIDRE Yes! Of course I do! My grandson is a thousand miles away and I can’t leave the God damned house.

Agoraphobia

Diagnostic Criteria

300.22 (F40.00)

A. Marked fear or anxiety about two (or more) of the following five situations:

1. Using public transportation (e.g., automobiles, buses, trains, ships, planes).

2. Being in open spaces (e.g., parking lots, marketplaces, bridges).

3. Being in enclosed places (e.g., shops, theaters, cinemas).

4. Standing in line or being in a crowd.

5. Being outside of the home alone.

B. The individual fears or avoids these situations because of thoughts that escape might be difficult or help might not be available in the event of developing panic-like symptoms or other incapacitating or embarrassing symptoms (e.g., fear of falling in the elderly; fear of incontinence).

C. The agoraphobic situations almost always provoke fear or anxiety.

D. The agoraphobic situations are actively avoided, require the presence of a companion, or are endured with intense fear or anxiety.

E. The fear or anxiety is out of proportion to the actual danger posed by the agoraphobic situations and to the sociocultural context.

F. The fear, anxiety, or avoidance is persistent, typically lasting for 6 months or more.

G. The fear, anxiety, or avoidance causes clinically significant distress or impairment in social, occupational, or other important areas of functioning.

H. If another medical condition (e.g., inflammatory bowel disease, Parkinson’s disease) is present, the fear, anxiety, or avoidance is clearly excessive.

I. The fear, anxiety, or avoidance is not better explained by the symptoms of another mental disorder—for example, the symptoms are not confined to specific phobia, situational type; do not involve only social situations (as in social anxiety disorder); and are not related exclusively to obsessions (as in obsessive-compulsive disorder), perceived defects or flaws in physical appearance (as in body dysmorphic disorder), reminders of traumatic events (as in posttraumatic stress disorder), or fear of separation (as in separation anxiety disorder).

Note: Agoraphobia is diagnosed irrespective of the presence of panic disorder. If an individual’s presentation meets criteria for panic disorder and agoraphobia, both diagnoses should be assigned.

Diagnostic Features

The essential feature of agoraphobia is marked, or intense, fear or anxiety triggered by the real or anticipated exposure to a wide range of situations (Criterion A). The diagnosis requires endorsement of symptoms occurring in at least two of the following five situations: 1) using public transportation , such as automobiles, buses, trains, ships, or planes; 2) being in open spaces, such as parking lots, marketplaces, or bridges; 3) being in enclosed spaces, such as shops, theaters, or cinemas; 4) standing in line or being in a crowd; or 5) being outside of the home alone. The examples for each situation are not exhaustive; other situations may be feared(Wittchen et al. 2010). When experiencing fear and anxiety cued by such situations, individuals typically experience thoughts that something terrible might happen (Criterion B). Individuals frequently believe that escape from such situations might be difficult (e.g., “can’t get out of here”) or that help might be unavailable (e.g., “there is nobody to help me”) when panic-like symptoms or other incapacitating or embarrassing symptoms occur. “Panic-like symptoms” refer to any of the 13 symptoms included in the criteria for panic attack, such as dizziness, faintness, and fear of dying. “Other incapacitating or embarrassing symptoms” include symptoms such as vomiting and inflammatory bowel symptoms, as well as, in older adults, a fear of falling or, in children, a sense of disorientation and getting lost.

The amount of fear experienced may vary with proximity to the feared situation and may occur in anticipation of or in the actual presence of the agoraphobic situation. Also, the fear or anxiety may take the form of a full- or limited-symptom panic attack (i.e., an expected panic attack). Fear or anxiety is evoked nearly every time the individual comes into contact with the feared situation (Criterion C). Thus, an individual who becomes anxious only occasionally in an agoraphobic situation (e.g., becomes anxious when standing in line on only one out of every five occasions) would not be diagnosed with agoraphobia(Craske et al. 2010; Wittchen et al. 2010). The individual actively avoids the situation or, if he or she either is unable or decides not to avoid it, the situation evokes intense fear or anxiety (Criterion D). Active avoidance means the individual is currently behaving in ways that are intentionally designed to prevent or minimize contact with agoraphobic situations. Avoidance can be behavioral (e.g., changing daily routines, choosing a job nearby to avoid using public transportation, arranging for food delivery to avoid entering shops and supermarkets) as well as cognitive (e.g., using distraction to get through agoraphobic situations) in nature. The avoidance can become so severe that the person is completely homebound. Often, an individual is better able to confront a feared situation when accompanied by a companion, such as a partner, friend, or health professional.

The fear, anxiety, or avoidance must be out of proportion to the actual danger posed by the agoraphobic situations and to the sociocultural context (Criterion E). Differentiating clinically significant agoraphobic fears from reasonable fears (e.g., leaving the house during a bad storm) or from situations that are deemed dangerous (e.g., walking in a parking lot or using public transportation in a high-crime area) is important for a number of reasons. First, what constitutes avoidance may be difficult to judge across cultures and sociocultural contexts (e.g., it is socioculturally appropriate for orthodox Muslim women in certain parts of the world to avoid leaving the house alone, and thus such avoidance would not be considered indicative of agoraphobia). Second, older adults are likely to overattribute their fears to age-related constraints and are less likely to judge their fears as being out of proportion to the actual risk(Wolitzky-Taylor et al. 2010). Third, individuals with agoraphobia are likely to overestimate danger in relation to panic-like or other bodily symptoms(
Chambless et al. 1984

McNally and Lorenz 1987
). Agoraphobia should be diagnosed only if the fear, anxiety, or avoidance persists (Criterion F) and if it causes clinically significant distress or impairment in social, occupational, or other important areas of functioning (Criterion G). The duration of “typically lasting for 6 months or more” is meant to exclude individuals with short-lived, transient problems. However, the duration criterion should be used as a general guide, with allowance for some degree of flexibility.

Associated Features Supporting Diagnosis

In its most severe forms, agoraphobia can cause individuals to become completely homebound, unable to leave their home and dependent on others for services or assistance to provide even for basic needs. Demoralization and depressive symptoms, as well as abuse of alcohol and sedative medication as inappropriate self-medication strategies, are common.

Prevalence

Every year approximately 1.7% of adolescents and adults have a diagnosis of agoraphobia (
K
essler et al. 2012; Wittchen et al. 2011). Females are twice as likely as males to experience agoraphobia (Wittchen et al. 2010). Agoraphobia may occur in childhood, but incidence peaks in late adolescence and early adulthood(Beesdo et al. 2009; 
Bittner et al. 2007
). Twelve-month prevalence in individuals older than 65 years is 0.4%(Kessler et al. 2006). Prevalence rates do not appear to vary systematically across cultural/racial groups(
Gustavsson et al. 2011

Lew
is-Fernández et al. 2010).

Development and Course

The percentage of individuals with agoraphobia reporting panic attacks or panic disorder preceding the onset of agoraphobia ranges from 30% in community samples to more than 50% in clinic samples. The majority of individuals with panic disorder show signs of anxiety and agoraphobia before the onset of panic disorder (
Fava et al. 1992

Garvey et al. 1988
).

In two-thirds of all cases of agoraphobia, initial onset is before age 35 years. There is a substantial incidence risk in late adolescence and early adulthood, with indications for a second high incidence risk phase after age 40 years. First onset in childhood is rare. The overall mean age at onset for agoraphobia is 17 years, although the age at onset without preceding panic attacks or panic disorder is 25–29 years(Nocon et al. 2008Wittchen et al. 2010).

The course of agoraphobia is typically persistent and chronic. Complete remission is rare (10%), unless the agoraphobia is treated(Emmelkamp and Wittchen 2009). With more severe agoraphobia, rates of full remission decrease, whereas rates of relapse and chronicity increase. A range of other disorders, in particular other anxiety disorders, depressive disorders, substance use disorders, and personality disorders, may complicate the course of agoraphobia. The long-term course and outcome of agoraphobia are associated with substantially elevated risk of secondary major depressive disorder, persistent depressive disorder (dysthymia), and substance use disorders.

The clinical features of agoraphobia are relatively consistent across the lifespan, although the type of agoraphobic situations triggering fear, anxiety, or avoidance, as well as the type of cognitions, may vary. For example, in children, being outside of the home alone is the most frequent situation feared, whereas in older adults, being in shops, standing in line, and being in open spaces are most often feared(Wittchen et al. 2010). Also, cognitions often pertain to becoming lost (in children), to experiencing panic-like symptoms (in adults), to falling (in older adults).

The low prevalence of agoraphobia in children could reflect difficulties in symptom reporting, and thus assessments in young children may require solicitation of information from multiple sources, including parents or teachers(Beesdo et al. 2009). Adolescents, particularly males, may be less willing than adults to openly discuss agoraphobic fears and avoidance; however, agoraphobia can occur prior to adulthood and should be assessed in children and adolescents. In older adults, comorbid somatic symptom disorders, as well as motor disturbances (e.g., sense of falling or having medical complications), are frequently mentioned by individuals as the reason for their fear and avoidance(
McCabe et al. 2006
). In these instances, care is to be taken in evaluating whether the fear and avoidance are out of proportion to the real danger involved.

Risk and Prognostic Factors

Temperamental

Behavioral inhibition and neurotic disposition (i.e., negative affectivity [neuroticism] and anxiety sensitivity) are closely associated with agoraphobia but are relevant to most anxiety disorders (phobic disorders, panic disorder, generalized anxiety disorder)(Rohrbacher et al. 2008Wittchen et al. 2010). Anxiety sensitivity (the disposition to believe that symptoms of anxiety are harmful) is also characteristic of individuals with agoraphobia (
Hayward and Wilson 2007
).

Environmental

Negative events in childhood (e.g., separation, death of parent) and other stressful events, such as being attacked or mugged, are associated with the onset of agoraphobia. Furthermore, individuals with agoraphobia describe the family climate and child-rearing behavior as being characterized by reduced warmth and increased overprotection(Wittchen et al. 2010).

Genetic and physiological

Heritability for agoraphobia is 61%(Kendler et al. 1999). Of the various phobias, agoraphobia has the strongest and most specific association with the genetic factor that represents proneness to phobias(
Kendler et al. 1992a

Kendler et al. 1992b
).

Gender-Related Diagnostic Issues

Females have different patterns of comorbid disorders than males. Consistent with gender differences in the prevalence of mental disorders, males have higher rates of comorbid substance use disorders.

Functional Consequences of Agoraphobia

Agoraphobia is associated with considerable impairment and disability in terms of role functioning, work productivity, and disability days. Agoraphobia severity is a strong determinant of the degree of disability, irrespective of the presence of comorbid panic disorder, panic attacks, and other comorbid conditions(
Kessler et al. 2006
Wittchen et al. 2010). More than one-third of individuals with agoraphobia are completely homebound and unable to work.

Differential Diagnosis

When diagnostic criteria for agoraphobia and another disorder are fully met, both diagnoses should be assigned, unless the fear, anxiety, or avoidance of agoraphobia is attributable to the other disorder. Weighting of criteria and clinical judgment may be helpful in some cases.

Specific phobia, situational type

Differentiating agoraphobia from situational specific phobia can be challenging in some cases, because these conditions share several symptom characteristics and criteria. Specific phobia, situational type, should be diagnosed versus agoraphobia if the fear, anxiety, or avoidance is limited to one of the agoraphobic situations. Requiring fears from two or more of the agoraphobic situations is a robust means for differentiating agoraphobia from specific phobias, particularly the situational subtype. Additional differentiating features include the cognitive ideation. Thus, if the situation is feared for reasons other than panic-like symptoms or other incapacitating or embarrassing symptoms (e.g., fears of being directly harmed by the situation itself, such as fear of the plane crashing for individuals who fear flying), then a diagnosis of specific phobia may be more appropriate.

Separation anxiety disorder

Separation anxiety disorder can be best differentiated from agoraphobia by examining cognitive ideation. In separation anxiety disorder, the thoughts are about detachment from significant others and the home environment (i.e., parents or other attachment figures), whereas in agoraphobia the focus is on panic-like symptoms or other incapacitating or embarrassing symptoms in the feared situations.

Social anxiety disorder (social phobia)

Agoraphobia should be differentiated from social anxiety disorder based primarily on the situational clusters that trigger fear, anxiety, or avoidance and the cognitive ideation. In social anxiety disorder, the focus is on fear of being negatively evaluated.

Panic disorder

When criteria for panic disorder are met, agoraphobia should not be diagnosed if the avoidance behaviors associated with the panic attacks do not extend to avoidance of two or more agoraphobic situations.

Acute stress disorder and posttraumatic stress disorder

Acute stress disorder and posttraumatic stress disorder (PTSD) can be differentiated from agoraphobia by examining whether the fear, anxiety, or avoidance is related only to situations that remind the individual of a traumatic event. If the fear, anxiety, or avoidance is restricted to trauma reminders, and if the avoidance behavior does not extend to two or more agoraphobic situations, then a diagnosis of agoraphobia is not warranted.

Major depressive disorder

In major depressive disorder, the individual may avoid leaving home because of apathy, loss of energy, low self-esteem, and anhedonia. If the avoidance is unrelated to fears of panic-like or other incapacitating or embarrassing symptoms, then agoraphobia should not be diagnosed.

Other medical conditions

Agoraphobia is not diagnosed if the avoidance of situations is judged to be a physiological consequence of a medical condition. This determination is based on history, laboratory findings, and a physical examination. Other relevant medical conditions may include neurodegenerative disorders with associated motor disturbances (e.g., Parkinson’s disease, multiple sclerosis), as well as cardiovascular disorders. Individuals with certain medical conditions may avoid situations because of realistic concerns about being incapacitated (e.g., fainting in an individual with transient ischemic attacks) or being embarrassed (e.g., diarrhea in an individual with Crohn’s disease). The diagnosis of agoraphobia should be given only when the fear or avoidance is clearly in excess of that usually associated with these medical conditions.

Comorbidity

The majority of individuals with agoraphobia also have other mental disorders. The most frequent additional diagnoses are other anxiety disorders (e.g., specific phobias, panic disorder, social anxiety disorder), depressive disorders (major depressive disorder), PTSD, and alcohol use disorder. Whereas other anxiety disorders (e.g., separation anxiety disorder, specific phobias, panic disorder) frequently precede onset of agoraphobia, depressive disorders and substance use disorders typically occur secondary to agoraphobia(
