Agoraphobia vs Claustrophobia: Escape, Enclosure, and Avoidance
Updated: Oct 8
Author: Ukrainian Psychological Hub · Published: October 1, 2026 · Editorial Policy
Agoraphobia and claustrophobia are often described as opposites: fear of open spaces versus fear of closed spaces. That shortcut is clinically misleading. Agoraphobia is organized around a broader pattern of situations in which escape may feel difficult or help may seem unavailable if panic-like, incapacitating, or embarrassing symptoms occur. Claustrophobia is a common descriptive term for marked fear of enclosed or confined spaces and, when the pattern meets diagnostic requirements, it is usually classified within specific phobia rather than as a separate stand-alone disorder. The American Psychiatric Association describes agoraphobia and specific phobia as distinct anxiety disorders, while NIMH explicitly includes enclosed places among the situations that can occur in agoraphobia.
The overlap is therefore real. An elevator, subway car, airplane, tunnel, MRI scanner, windowless room, or crowded venue can trigger either pattern. What distinguishes them is not the architecture alone. Clinicians examine the focus of apprehension, the breadth of feared situations, what the person expects will happen, how avoidance functions, whether panic symptoms are expected or unexpected, how persistent and impairing the pattern is, and whether another mental or medical condition explains it better. For the broader diagnostic context, see Agoraphobia: Symptoms, Causes, Diagnosis, and Treatment and Agoraphobia vs Specific Phobia: Broad Situational Patterns vs Focused Fear.
This article owns the narrower comparison intent: agoraphobia versus claustrophobia, with special attention to escape, enclosure, panic, avoidance, diagnostic mapping, assessment, and treatment implications. It does not treat every fear of a small room as a disorder, and it does not treat every fear of being unable to leave as agoraphobia.
Agoraphobia vs Claustrophobia: The Short Answer
Agoraphobia is a formal anxiety-disorder diagnosis. In DSM-5-TR, it involves marked fear or anxiety about two or more characteristic situation classes: public transportation, open spaces, enclosed places, lines or crowds, and being outside the home alone. The central concern is that escape may be difficult or help may not be available if panic-like or other incapacitating or embarrassing symptoms occur. The pattern is persistent, out of proportion to actual danger, and clinically distressing or impairing. APA guidance and NIMH guidance both emphasize this multi-situation structure.
Claustrophobia describes fear of enclosed or confined spaces. It can be mild, situational, and nonclinical, or it can become persistent and impairing enough to fit specific phobia. The current APA Severity Measure for Specific Phobia lists tunnels and enclosed spaces among the situations assessed under specific phobia. ICD-11 likewise keeps agoraphobia and specific phobia as separate diagnoses within anxiety or fear-related disorders; the WHO ICD-11 Clinical Descriptions and Diagnostic Requirements is the current global clinical classification reference.
The most useful practical question is therefore not “Is this place open or closed?” It is “What pattern of fear is this situation part of?”
The Core Difference: Escape Versus Enclosure
Agoraphobia is organized around escape, help, and a broader situation pattern
In agoraphobia, the feared setting matters because of what it would mean if intense symptoms or another feared event occurred there. A person may think, “I could not get out quickly,” “No one could help me,” “I might faint and be trapped,” or “I could have a panic-like episode where leaving would be difficult.” This organizing concern can connect apparently different settings: a bus, an open square, a theater, a line at a store, a bridge, and being far from home alone.
The two-or-more-situation rule in DSM-5 was added in part to improve the boundary between agoraphobia and specific phobia. Reviews that informed modern classification identified this boundary as a major diagnostic issue. See LeBeau et al. (2010) and Asmundson, Taylor, and Smits (2014).
Claustrophobia is organized around enclosed-space threat
Claustrophobic fear is more tightly tied to enclosure, confinement, and the anticipated consequences of being in a restricted space. Research using the Claustrophobia Questionnaire found two related dimensions: fear of restriction and fear of suffocation. Subsequent validation work reproduced this two-factor structure and showed that the questionnaire predicts fear responses during claustrophobic exposure. Van Diest and colleagues (2010) provide one example.
That does not mean every person with claustrophobic fear consciously reports “restriction” or “suffocation,” and it does not mean the questionnaire establishes a diagnosis. It means those two fear domains are well-supported ways of describing the phenomenology of claustrophobic fear.
An enclosed place can belong to either pattern
An elevator is the clearest example. Someone may fear the elevator because it is small, sealed, and constraining, with thoughts centered on being unable to tolerate confinement or breathe comfortably. That pattern fits claustrophobic fear and may map clinically to situational specific phobia. Another person may fear the same elevator mainly because escape would be difficult if dizziness, panic-like sensations, loss of control, or another incapacitating event occurred. If similar fear extends across multiple agoraphobic situation classes, the elevator can be part of agoraphobia.
The building does not diagnose the disorder. The fear structure does.
Why “Open Spaces vs Closed Spaces” Is the Wrong Shortcut
The popular contrast suggests that agoraphobia means fear of open places while claustrophobia means fear of closed places. Modern diagnostic criteria make this impossible as a complete explanation because enclosed places are explicitly one of the agoraphobic situation classes. A person with agoraphobia can fear trains, elevators, cinemas, stores, tunnels, or other enclosed places. NIMH lists enclosed spaces alongside public transportation, open spaces, crowds or lines, and being outside the home alone.
The historical name “agoraphobia” can reinforce the misconception because “agora” evokes a public square. Contemporary diagnosis is based on the current clinical pattern rather than the literal etymology. Someone can have agoraphobia without a particular fear of open fields, and someone can fear an enclosed room without having agoraphobia.
This is also why “I hate elevators” and “I cannot go anywhere alone” are not interchangeable clinical statements. One points toward a focused trigger; the other may indicate a broader functional pattern, but either statement still requires assessment before a diagnosis is made.
What Agoraphobia Means Clinically
The characteristic situation classes
DSM-5-TR describes five agoraphobic situation classes: using public transportation; being in open spaces; being in enclosed places; standing in line or being in a crowd; and being outside the home alone. The diagnosis requires fear or anxiety across at least two of these classes. For the dedicated criterion-level explanation, see Agoraphobia DSM-5-TR Criteria Explained.
ICD-11 also treats agoraphobia as a distinct anxiety or fear-related disorder characterized by fear across multiple situations where escape or help may be difficult. The classification architecture is discussed in the WHO ICD-11 CDDR and in the peer-reviewed review of anxiety and fear-related disorders in ICD-11. For the Hub's dedicated ICD page, see Agoraphobia ICD-11 Diagnostic Requirements Explained.
The feared consequence matters
The fear in agoraphobia is not simply “this place is dangerous.” It is often conditional: “If something happens to me here, I may not be able to leave or get help.” Panic-like symptoms are a classic feared outcome, but current classification does not require panic disorder. The person may fear fainting, losing balance, vomiting, becoming incontinent, becoming disoriented, or experiencing another incapacitating or embarrassing event in a setting where exit or assistance feels difficult.
Modern separation of agoraphobia from panic disorder reflects evidence that agoraphobia can exist independently. Wittchen and colleagues' diagnostic review argued for agoraphobia as an independent disorder, and current DSM-5-TR and ICD-11 preserve that separation.
Breadth is diagnostically important
A focused fear of one elevator, one tunnel, or one type of enclosed room does not by itself establish agoraphobia. The broader pattern matters. Clinicians ask whether the same escape-or-help concern extends to public transportation, crowds, open spaces, being alone away from home, or other agoraphobic situations. This is one reason the direct comparison with specific phobia matters so much.
What Claustrophobia Means Clinically
Claustrophobia is a descriptive fear term, not a separate DSM-5-TR disorder
“Claustrophobia” is widely used in clinical practice, research, and everyday language, but DSM-5-TR does not give it a separate stand-alone diagnosis. When enclosed-space fear is persistent, disproportionate, and impairing enough to meet diagnostic requirements, the formal diagnosis is typically specific phobia, situational type. The APA's current specific-phobia severity measure explicitly groups enclosed spaces with other situational examples such as tunnels, driving, and flying.
The same principle applies to ICD-11: specific phobia and agoraphobia are separate diagnoses, and clinically significant fear of closed spaces maps to specific phobia rather than to a distinct “claustrophobia disorder.” This classification point prevents a popular fear label from being mistaken for an additional diagnostic category.
Restriction and suffocation are recurring claustrophobic themes
The best-known psychometric model of claustrophobia proposes two related fear domains: restriction and suffocation. Restriction concerns being unable to move freely, leave, or tolerate confinement. Suffocation concerns not getting enough air, choking, or being unable to breathe. Radomsky et al. (2001) developed the Claustrophobia Questionnaire around these dimensions and reported good predictive and discriminant validity.
These dimensions can interact. A person in a packed elevator may feel both physically restricted and afraid of not being able to breathe. Another person may tolerate a narrow hallway but fear an MRI bore because head and body movement feel constrained. A third may fear a locked room mainly because the door cannot be opened immediately.
Claustrophobic fear can be intense without being a disorder
Discomfort in a cramped elevator, tunnel, aircraft cabin, or MRI scanner is not automatically a specific phobia. Clinical diagnosis depends on persistence, disproportionality, avoidance or intense endurance, distress or impairment, and differential diagnosis. The broad review by Eaton, Bienvenu, and Miloyan (2018) emphasizes that specific phobias involve both fear and avoidance and can persist for years, but diagnosis remains more than the presence of fear alone.
Same Place, Different Fear: Concrete Examples
Elevator
Claustrophobic pattern: “The doors will close, I will be trapped in a tiny box, I will not be able to breathe, and I need to get out.” The fear is tightly tied to enclosure and confinement. Agoraphobic pattern: “If I become dizzy or panic in the elevator, I cannot leave until the doors open and help may not reach me.” The elevator is one member of a broader escape-and-help pattern.
Subway or train
Claustrophobic pattern: fear rises mainly when the car is underground, crowded, sealed, or physically confining. Agoraphobic pattern: the person fears the inability to leave between stops, the distance from a safe place, or the difficulty of receiving help if severe symptoms occur; buses, trains, queues, crowds, and being away from home alone may all become linked.
Airplane
An aircraft can support several different fear structures. Claustrophobic fear may center on the sealed cabin and inability to open a door. A situational specific phobia may center on flying itself, turbulence, or a feared crash. Agoraphobic fear may center on being unable to escape or obtain help during intense symptoms, especially if similar concerns occur across other forms of transport and public settings. One person can also have more than one clinically significant fear pattern.
MRI scanner
MRI is a classic enclosed-space trigger because the person lies inside a narrow bore and must remain relatively still. Research shows that anxiety and claustrophobic reactions can interfere with imaging. A systematic review by Munn and Jordan examined strategies such as scanner design, cognitive-behavioral approaches, positioning, information, and staff support. A 2026 clinical review likewise describes MRI claustrophobia as an ongoing practical problem.
MRI fear by itself does not establish agoraphobia. It can reflect a focused claustrophobic or procedural fear. A broader escape-and-help pattern across multiple situation classes would raise a different diagnostic question.
Crowded store or theater
A crowded store can feel claustrophobic because bodies, aisles, or walls restrict movement. It can be agoraphobic because leaving quickly may feel difficult or help may seem unavailable. It can also be socially threatening if the core fear is scrutiny or humiliation. The visible setting is shared; the focus of apprehension differentiates the diagnostic possibilities.
How Clinicians Distinguish the Two
1. What exactly is feared?
Assessment starts with the expected catastrophe or threat. Is the person afraid of enclosure, physical restriction, or suffocation? Are they afraid of panic-like symptoms, fainting, falling, losing bowel control, or another incapacitating event where escape or help would be difficult? Are they afraid of a crash, contamination, social judgment, trauma reminders, or a genuine environmental hazard? The content of the fear often clarifies the diagnostic owner.
2. How broad is the trigger pattern?
Claustrophobic fear is typically concentrated in enclosed or confining settings. Agoraphobia spans multiple characteristic situation classes. A clinician therefore maps feared places rather than asking about a single favorite example. Elevators, tunnels, buses, trains, malls, queues, bridges, theaters, being far from home, and being alone outside the home can reveal whether the pattern is circumscribed or networked across agoraphobic domains.
3. What happens if escape is easy?
The answer can be informative. If an open door, larger cabin, aisle seat, visible exit, or ability to stop the situation sharply reduces fear, restriction or escape may be central. Yet this is not a diagnostic test. Both agoraphobic and claustrophobic fear can decrease when exit feels easier, and both can involve safety behaviors built around exits.
4. Is a companion required?
Some people with agoraphobia can enter feared settings only with a trusted companion. That pattern fits the broader agoraphobic logic of perceived safety, assistance, and escape. People with claustrophobic fear may also seek accompaniment, so companionship alone does not determine diagnosis. The clinician asks what the companion is expected to prevent or help manage.
5. How persistent and impairing is the pattern?
Normal discomfort, a transient stress reaction, and a clinical disorder are different things. Assessment examines duration, severity, avoidance, distress, work or school interference, travel limitations, medical-procedure interference, and whether the fear is out of proportion to actual danger. For the broader assessment framework, see How Is Anxiety Diagnosed? Assessment, History, and Differential Diagnosis.
Avoidance Can Look Similar While Serving Different Fears
Both patterns can produce avoidance: taking stairs instead of elevators, refusing underground trains, choosing an aisle seat, avoiding tunnels, skipping crowded events, postponing MRI, traveling only with a companion, keeping doors open, standing near exits, or leaving early. The behavior itself does not tell you which disorder is present.
Avoidance often brings immediate relief, and that relief can make avoidance more likely next time. Over time, the person's world can become organized around preventing fear rather than testing what would actually happen. This maintenance process is covered in Anxiety and Avoidance: How Avoidance Maintains Fear.
Safety behaviors deserve the same analysis. Exit scanning, sitting by doors, carrying “rescue” items, repeatedly checking ventilation, traveling only with a trusted person, or leaving before fear peaks may reduce distress in the moment. Their clinical meaning depends on the belief they are protecting against and how rigidly they constrain functioning.
Panic Attacks Do Not Settle the Diagnosis
A panic attack can occur in agoraphobia, specific phobia, social anxiety disorder, PTSD, other psychiatric conditions, medical conditions, substance-related states, or without a diagnosed mental disorder. A panic attack is an episode, not a synonym for panic disorder. APA notes that panic attacks can be expected in response to feared objects or situations or can occur unexpectedly.
Claustrophobic exposure can provoke abrupt surges of fear, shortness of breath, palpitations, dizziness, trembling, choking sensations, and an urgent need to escape. Agoraphobic situations can provoke the same symptoms. What matters diagnostically is whether the attacks are expected and cue-bound, whether there are recurrent unexpected attacks, what fear follows them, and how the broader avoidance pattern is organized.
For these distinctions, see Panic Attack: Symptoms, Causes, Duration, and What to Do, Panic Disorder: Symptoms, Causes, Diagnosis, and Treatment, Panic Disorder vs Agoraphobia: What Is the Difference?, and Panic Disorder vs Specific Phobia: Unexpected Panic vs Cue-Bound Fear.
New or severe chest pain, major breathing difficulty, fainting, new neurologic symptoms, seizure-like activity, or a new sustained or irregular heartbeat should not be assumed to be anxiety because they occur during fear. Online symptom matching cannot reliably exclude medical causes.
Can Someone Have Both Agoraphobia and Claustrophobia?
Yes. A person can have agoraphobia and also have a focused enclosed-space fear that independently meets criteria for specific phobia. Co-occurrence is possible because diagnostic categories describe patterns, not mutually exclusive personality types. The key question is whether each pattern has its own clinically significant features rather than whether the person can name more than one feared situation.
The opposite is also common: apparent overlap that is better explained by one diagnosis. Someone may describe “claustrophobia” because elevators are a major trigger, but assessment reveals the same escape-and-help fear across trains, crowds, theaters, lines, and being alone away from home. In that case, the enclosed-space fear may be one expression of agoraphobia rather than a separate specific phobia.
Or the person may fear only elevators, MRI scanners, and tightly enclosed rooms because of restriction and suffocation concerns, with no broader agoraphobic pattern. That presentation points toward the specific-phobia territory.
Important Differential Diagnoses and Neighboring Explanations
Panic disorder
Panic disorder is defined by recurrent unexpected panic attacks plus persistent concern or maladaptive behavior related to further attacks. Agoraphobia can occur with it or without it. Claustrophobic panic is often expected in a specific cue. The presence of panic symptoms alone therefore does not convert either fear into panic disorder.
Social anxiety disorder
Crowded or enclosed social settings can be avoided because of fear of scrutiny, embarrassment, or negative evaluation. If the core fear is social judgment rather than enclosure or difficulty escaping during incapacitating symptoms, social anxiety disorder may be the more relevant diagnostic territory.
Trauma-related fear
An elevator, locked room, vehicle, or medical scanner can become a trauma reminder. When the fear is organized around re-experiencing, trauma cues, hyperarousal, or other trauma-related symptoms, the diagnostic formulation may differ from both agoraphobia and specific phobia. PTSD is not classified as an anxiety disorder in current DSM-5-TR or ICD-11 architecture.
Medical, vestibular, respiratory, and situational factors
Breathing difficulty, dizziness, fainting, cardiac symptoms, vestibular problems, medication effects, substance use, heat, crowding, poor ventilation, or a genuinely unsafe environment can produce fear or escape behavior. A psychiatric label should not replace medical assessment when symptoms are new, severe, atypical, or plausibly explained by a physical condition.
Normal fear and preference
Some people simply dislike small rooms, packed elevators, underground transport, or MRI scanners. Preference, discomfort, and ordinary fear become clinically relevant when the pattern is persistent, disproportionate, difficult to control through ordinary adaptation, and meaningfully distressing or impairing. A single unpleasant experience does not establish either diagnosis.
Assessment: What a Good Evaluation Looks For
A competent assessment does more than ask whether someone is afraid of enclosed spaces. It reconstructs the fear network. Clinicians typically ask which situations trigger fear, which are merely uncomfortable, what the person predicts will happen, whether fear occurs before exposure, how quickly it rises, whether the person escapes, what safety behaviors are used, whether a companion is needed, and what activities have been lost because of avoidance.
For agoraphobia, assessment also examines the full set of characteristic situation classes and the escape-or-help theme. For claustrophobic fear, assessment examines the range of enclosed-space triggers and the relative importance of restriction, suffocation, entrapment, bodily sensations, and catastrophic expectations.
Questionnaires can support this process but do not replace it. The Claustrophobia Questionnaire measures claustrophobic fear dimensions. APA's disorder-specific severity measures are intended to support clinical evaluation and monitoring, not to act as stand-alone diagnostic tests. A questionnaire score is therefore a symptom or severity signal, not a diagnosis.
Treatment: Related Tools, Different Targets
Exposure-based treatment is central for clinically significant claustrophobic specific phobia
Specific-phobia treatment has a strong exposure evidence base. A 2022 meta-analysis by Odgers and colleagues found large effects for both single-session and multi-session in vivo exposure in clinical specific-phobia samples. Earlier meta-analytic work and reviews also support exposure as the preferred psychological treatment for specific phobia.
Claustrophobia-specific trials are smaller than the broader specific-phobia literature. In a randomized study of 46 patients, Öst and colleagues found that one-session exposure, five-session exposure, and five-session cognitive therapy all performed better than a wait-list condition. More recent experimental work continues to study how cognitive expectancy and exposure learning interact in claustrophobic fear; for example, Krause, Koerner, and Antony (2022) found substantial improvement regardless of whether brief cognitive restructuring occurred before or after exposure.
These studies support exposure-based and cognitive-behavioral approaches, but they do not justify a single self-directed exposure recipe for everyone. Treatment is usually graded to the person's fear structure, medical context, and functional goals.
Agoraphobia treatment targets a broader avoidance network
Agoraphobia treatment often uses CBT with in vivo exposure to avoided situations, but the exposure plan is organized around the broader agoraphobic network rather than one enclosed-space cue. A systematic review and meta-analysis by Breuninger and colleagues describes exposure as an effective and central component of CBT for agoraphobia and examined cognitive change as a mechanism.
If panic-related bodily sensations are part of the person's fear structure, treatment may also address catastrophic interpretations of those sensations and may include interoceptive exercises within a clinically appropriate CBT plan. That does not mean interoceptive exposure is automatically indicated for every person with agoraphobia or claustrophobia.
For treatment detail, see Agoraphobia Treatment: CBT, Exposure Therapy, Medication, and Self-Help and Exposure Therapy for Agoraphobia: How Graded Exposure Works.
Medication evidence should not be transferred from one diagnosis to the other
Medication can be part of care for some anxiety presentations, especially when other disorders are present, but the evidence base is not interchangeable across agoraphobia, panic disorder, and specific phobia. NIMH notes that medication may sometimes be used to relieve phobia symptoms in specific circumstances, while psychotherapy—particularly CBT and exposure—is the primary treatment approach for phobias. This comparison page therefore does not turn medication options for one disorder into recommendations for the other.
If Enclosed Spaces Interfere With MRI, Travel, or Daily Life
A focused problem can still have major practical consequences. MRI fear can lead to delayed imaging, incomplete scans, or requests for sedation. Fear of elevators can restrict work or housing choices. Fear of airplanes, tunnels, or subway cars can narrow travel. The practical impact matters even when the fear does not fit agoraphobia.
For a planned MRI, telling the radiology team in advance is useful because facilities may have procedural options, preparation strategies, scanner configurations, communication methods, or other supports. The evidence across imaging studies is heterogeneous, but systematic reviews have found potentially helpful effects from several patient-centered and behavioral approaches. The treatment decision belongs to the medical and mental-health context, especially when sedation or medication is being considered.
For everyday travel and mobility, the most useful first step is to identify the pattern rather than force a label: Which settings are avoided? What is feared? How broad is the avoidance? What safety behaviors are required? What activities have become impossible or costly? That information guides whether the problem is best understood as focused claustrophobic fear, agoraphobia, another anxiety disorder, or something else.
When Professional Assessment Is Worthwhile
Consider a clinical assessment when fear or avoidance repeatedly interferes with medical care, work, school, travel, relationships, independent mobility, or ordinary daily tasks; when the range of avoided situations is expanding; when panic attacks or severe physical symptoms complicate the picture; or when you are unsure whether the pattern is agoraphobia, specific phobia, panic disorder, trauma-related fear, or a medical issue.
Assessment is especially valuable when the label seems obvious but the pattern is not. “Claustrophobia” can be an accurate everyday description while the formal diagnosis is specific phobia, agoraphobia, another disorder, or no disorder at all. “Agoraphobia” can also be used casually for staying home, even when the defining escape-and-help pattern is absent.
Frequently Asked Questions
Is agoraphobia the opposite of claustrophobia?
No. Agoraphobia is not simply fear of open spaces, and enclosed places are one of its recognized situation classes. Claustrophobia is focused on enclosed or confined spaces and usually maps to specific phobia when diagnostic criteria are met.
Can agoraphobia include fear of elevators or tunnels?
Yes. Elevators, tunnels, trains, theaters, and other enclosed places can be part of agoraphobia when they belong to a broader pattern in which escape or help feels difficult. Fear of one enclosed setting by itself does not establish agoraphobia.
Is claustrophobia a diagnosis?
Claustrophobia is a recognized clinical and research term, but it is not a separate stand-alone DSM-5-TR diagnosis. Clinically significant claustrophobic fear is generally diagnosed under specific phobia when the relevant criteria are met.
Can claustrophobia cause a panic attack?
Yes. Exposure to a feared enclosed space can trigger an expected panic attack. That does not by itself mean the person has panic disorder, which requires a different pattern centered on recurrent unexpected panic attacks and their aftermath.
Does agoraphobia always involve panic attacks?
No. Panic disorder and agoraphobia are separate diagnoses. Agoraphobia can be organized around fear of panic-like symptoms or other incapacitating or embarrassing events even when recurrent panic attacks are absent.
Can someone have both agoraphobia and claustrophobia?
Yes. Both can be clinically significant if the person independently has a broader agoraphobic pattern and a circumscribed enclosed-space phobia. An assessment determines whether there are two disorders or one broader pattern with overlapping triggers.
Does fear of an MRI mean I have claustrophobia?
Not necessarily. MRI can provoke situational anxiety or claustrophobic fear in people without a clinical phobia. Diagnosis depends on the broader pattern, persistence, severity, avoidance, impairment, and differential assessment.
Does fear of elevators mean I have agoraphobia?
No. Elevator fear can reflect claustrophobic specific phobia, agoraphobia, panic-related concerns, trauma-related fear, or ordinary discomfort. The feared outcome and breadth of situations matter.
How are agoraphobia and claustrophobia treated differently?
Both may involve exposure-based CBT, but the target map differs. Claustrophobic specific-phobia treatment focuses on the enclosed-space fear and its predictions. Agoraphobia treatment addresses a broader network of avoided situations and the escape-or-help concerns that connect them, with additional panic-focused components when clinically relevant.
Can an online test tell the difference?
No. Screening and severity questionnaires can organize symptoms and monitor change, but they cannot establish the diagnosis or reliably perform the full differential assessment required to distinguish agoraphobia from specific phobia, panic disorder, trauma-related conditions, or medical causes.
