Criteria for Diagnosis
While symptoms of claustrophobia can vary significantly from one individual to another, professionals often rely on specific criteria to confirm a diagnosis. These criteria include:
a) Intense Fear
The individual exhibits an intense, persistent fear of closed or confined spaces. This fear is often described as irrational and out of proportion to any actual danger these spaces might present.
b) Immediate Anxiety Response
Exposure to the confined space, or even merely the thought of it, usually provokes an immediate anxiety response. This can range from mild unease to a full-blown panic attack.
c) Avoidance Behavior
Individuals with claustrophobia often go to great lengths to avoid situations that trigger their fears. This can lead to disruptions in daily life, such as avoiding elevators or certain modes of transportation.
d) Duration of Symptoms
For a claustrophobia diagnosis, the fear, anxiety, or avoidance must persist for six months or more, distinguishing it from a fleeting fear.
e) Impact on Daily Life
The phobia causes significant distress or impairment in the person’s social, occupational, or other crucial areas of functioning.
e) Exclusion of Other Disorders
The fear isn’t better attributed to another mental disorder, such as a generalized anxiety disorder, PTSD, or OCD, among others.
Differential Diagnosis
Differential Diagnosis (Distinguishing from other conditions)
Distinguishing claustrophobia from other conditions is crucial for effective treatment. This process, known as differential diagnosis, is essential to ensure patients receive the right interventions.
Other Specific Phobias
Claustrophobia is a type of specific phobia. It’s essential to distinguish it from other phobias like acrophobia (fear of heights) or agoraphobia (fear of situations where escape might be difficult). The primary distinguishing factor is the nature of the feared object or situation. Distinguishing between panic disorder with agoraphobia and claustrophobia can pose a diagnostic challenge. While both conditions involve a fear of feeling trapped, there are critical differences:
a) Underlying Fear
In panic disorder with agoraphobia, the primary fear revolves around experiencing a panic attack. This fear motivates their anxiety.
b) Fear of Open Spaces
Individuals with agoraphobia not only fear being trapped but also have anxiety in open places and situations where help may not be readily available in the event of a panic attack.
c) Uncued and Unexpected Panic Attacks
In cases of panic disorder with agoraphobia, patients typically experience at least some panic attacks that occur spontaneously and without an apparent trigger.
This distinction helps clinicians accurately diagnose and provide appropriate treatment for these related but distinct anxiety disorders.
Generalized Anxiety Disorder (GAD)
While GAD also involves excessive worrying, it’s more broad and not tied to a specific situation like claustrophobia. GAD patients tend to worry about various aspects of life, such as health, finances, or relationships.
Panic Disorder
People with claustrophobia may experience panic attacks, but not everyone with panic attacks has claustrophobia. In panic disorder, the attacks are often unprovoked and unpredictable, while in claustrophobia, they’re typically triggered by confinement or the idea of it.
PTSD
If a traumatic event causes the fear of enclosed spaces (e.g., getting trapped somewhere), it’s vital to determine whether the symptoms align more with claustrophobia or post-traumatic stress disorder. PTSD usually involves a broader range of symptoms, including flashbacks and emotional numbness.
OCD
Obsessive-compulsive disorder involves unwanted repetitive thoughts (obsessions) and actions (compulsions). A person with OCD might fear germs or harm, but their behaviors, like washing hands repeatedly or checking things, distinguish it from claustrophobia.
Three published measures are available to assess different aspects of claustrophobia, which is the fear of enclosed places. Each measure serves a somewhat distinct purpose:
Claustrophobia General Cognitions Questionnaire (CGCQ)
The Claustrophobia General Cognitions Questionnaire (CGCQ) is a tool designed to measure thoughts and beliefs associated with claustrophobic situations. It consists of 26 questions where individuals rate how likely they think various fear-related outcomes are when facing claustrophobia triggers. Responses are given on a scale of 1 (not likely) to 5 (very likely). Before answering these questions, individuals are asked to list claustrophobic situations that make them anxious. There is also a section at the end for recording any additional thoughts that arise during such situations.
The Claustrophobia Situations Questionnaire (CSQ) is another self-report scale that assesses both fear and avoidance in 42 different enclosed or claustrophobic scenarios. Each scenario is rated on a scale of 1 (not anxious/never avoid) to 5 (extremely anxious/always avoid). Similar to the CGCQ, there’s space at the end for noting any other anxiety-provoking or avoidance-related situations.
The CGCQ can be completed in about 5 minutes and provides results in three subscales: fear of loss of control, fear of suffocation, and fear of inability to escape. These subscales are calculated by summing specific items from the questionnaire.

This questionnaire focuses on identifying the specific beliefs that underlie an individual’s claustrophobia. It helps in understanding the thought patterns associated with the fear of enclosed spaces.

Claustrophobia Situations Questionnaire (CSQ)
This questionnaire is designed to evaluate the various situations that individuals with claustrophobia tend to avoid. It provides insight into the specific scenarios or environments that trigger their fear.
The Claustrophobia Situations Questionnaire (CSQ) is a self-report scale that assesses participants’ feelings of fear and avoidance in response to 42 different enclosed or claustrophobic situations. For each situation, participants rate their level of anxiety and the extent to which they tend to avoid it. Ratings are done using a five-point scale, with 1 indicating ‘not anxious/never avoid’ and 5 indicating ‘extremely anxious/always avoid.’ Additionally, there is space provided at the end of the questionnaire for participants to mention any other situations that provoke anxiety or avoidance.
Completing the CSQ typically takes 5 to 10 minutes. The questionnaire yields slightly different subscales for anxiety and avoidance items. For anxiety ratings, two CSQ anxiety subscales are generated: fear of entrapment and fear of physical confinement.
Similarly, for avoidance ratings, two CSQ avoidance subscales are generated based on factor analysis: avoidance of crowds and avoidance of physical confinement.
Claustrophobia Questionnaire
This questionnaire assesses claustrophobic fears in two separate dimensions. It measures fears related to situations that involve a perceived threat of suffocation and fears related to situations that involve a perceived threat of restriction. This distinction allows for a more nuanced understanding of the nature of claustrophobic anxieties
The Claustrophobia Questionnaire (CLQ) is a self-report scale consisting of 26 items. It is designed to measure fear in situations related to both suffocation and restriction. Each item is rated on a five-point scale, ranging from 0 (indicating no anxiety at all) to 4 (indicating extreme anxiety). Earlier versions of the CLQ, including its suffocation fear subscale, have been commonly used in research (Rachman & Taylor, 1993; McNally & Eke, 1996; Taylor & Rachman, 1994).
Completing the CLQ typically takes between 5 to 10 minutes. To calculate scores, the suffocation subscale score is determined by adding up the scores from the 14 items related to suffocation fears. Similarly, the restriction subscale score is calculated by adding up the scores from the 12 items related to restriction fears. Additionally, a total score can be obtained by adding together the scores from both subscales.
