Claustrophobia test

The claustrophobia test is a 26-item self-report instrument that measures anxiety in confined spaces across two clinically distinct subscales: fear of restriction — distress related to being unable to move freely or escape — and fear of suffocation — anxiety tied to sensations of air shortage or difficulty breathing in enclosed environments. Scores on each subscale are calculated independently, revealing which dimension of claustrophobic fear is most prominent and which should be prioritized in treatment.

Why Take a Claustrophobia Test

Claustrophobic symptoms vary significantly between individuals: some people are primarily triggered by physical restriction — such as crowded spaces, tight clothing, or locked rooms — while others react most strongly to sensations of suffocation, such as difficulty breathing through a nose clip or poor ventilation. Treating both as a single undifferentiated phobia leads to less effective therapy outcomes; an accurate claustrophobia assessment that separates these two dimensions allows clinicians to design exposure therapy or CBT programs that target the specific fear mechanism driving avoidance.

A claustrophobia questionnaire is also frequently used before medical procedures such as MRI scans to identify patients at risk of panic attacks in confined equipment, allowing staff to prepare appropriate support interventions in advance.

What the Assessment Measures

• Fear of Restriction (FR subscale) — anxiety related to being unable to move freely, exit an enclosed space, or escape a confined situation; commonly triggered by elevators, locked rooms, crowded transport, or tight spaces.
• Fear of Suffocation (FS subscale) — anxiety linked to sensations of air shortage or difficulty breathing in enclosed environments; triggered by situations such as wearing a nose clip, poor ventilation, or being inside MRI equipment.
• Total CLQ score — an overall index of claustrophobic symptoms severity combining both subscales, used to gauge overall phobia intensity and track change across treatment.

Who This Assessment Is For

The claustrophobia test is appropriate for adults who experience panic attacks, strong discomfort, or avoidance behavior in elevators, small rooms, crowded transport, tunnels, or medical scanning equipment. Therapists use the claustrophobia assessment during intake to establish which fear dimension — restriction or suffocation — is dominant, and to set a clear baseline for monitoring progress through exposure therapy or CBT. Medical staff use it to screen patients before MRI procedures to identify those who may need sedation, extended preparation, or open-bore alternatives. No clinical background is required — each item describes a concrete situation and respondents rate how much anxiety they would feel.

Clinical Validity and Use in Practice

The CLQ was developed by Radomsky, Rachman, and colleagues and published in the Journal of Anxiety Disorders (2001), where it demonstrated strong psychometric properties including good internal consistency across both subscales and adequate test-retest reliability. The two-factor structure — restriction and suffocation — has been replicated across clinical and non-clinical samples and aligns with theoretical models of specific phobia that distinguish between different anxiety disorder subtypes. Results are screening-level indicators of claustrophobic anxiety and should be interpreted alongside clinical history, current symptoms, and functional impairment rather than used as a standalone diagnosis. Repeated administration with identical instructions makes the instrument sensitive to treatment-related change, making it a practical outcome measure for exposure-based interventions targeting fear of enclosed spaces.
