Body Sensations Questionnaire (BSQ)
Also known as: BSQ
The Body Sensations Questionnaire (BSQ) is a 17-item self-report measure that assesses the degree to which respondents fear common bodily sensations associated with panic and anxiety (e.g., heart palpitations, dizziness, trembling). Developed by Chambless and colleagues in 1984, the BSQ captures a specific form of anxiety sensitivity—fear of interoceptive cues. It is widely used in clinical and research assessment of panic disorder, agoraphobia, and other anxiety conditions.

When to use it
The BSQ is indicated for assessing panic disorder, agoraphobia, and other anxiety conditions with prominent interoceptive fear. It is useful in pre-treatment evaluation to quantify bodily fear, treatment planning to prioritize interoceptive exposure, and monitoring response to anxiety interventions. Appropriate for adolescents and adults; less suitable for children under 12 or those with intellectual disability or severe cognitive impairment.
Strengths & limitations
- Measures a specific, clinically important construct: fear of bodily sensations, which is central to panic pathophysiology.
- Strong internal consistency (Cronbach's α = 0.86–0.91) and convergent validity with other panic-related measures.
- Sensitive to interoceptive exposure and cognitive-behavioral interventions; changes predict improvement in panic and avoidance.
- Brief (17 items) and readily administered; suitable for repeated measurement during treatment monitoring.
- Directly informs treatment planning; high scores clearly indicate the need for interoceptive exposure work.
- Focuses narrowly on fear of somatic sensations; does not assess cognitive appraisals (e.g., 'This means I'm dying') or behavioral avoidance.
- Item content is specific to panic-relevant sensations; less useful in anxiety conditions dominated by worry (e.g., generalized anxiety disorder).
- Test–retest reliability over weeks (r = 0.71–0.80) shows moderate fluctuation, suggesting BSQ is sensitive to state-level changes.
- Does not discriminate well between panic disorder and other anxiety or medical conditions with prominent somatic focus.
Frequently asked
How does the BSQ differ from the Anxiety Sensitivity Index (ASI)?
Both measure fear of bodily sensations, but the ASI also includes cognitive and social domains of anxiety sensitivity. The BSQ is more narrowly focused on fear of the sensations themselves, making it particularly useful for panic disorder where interoceptive fear is central. Some researchers use both to separately quantify sensation fear (BSQ) and broader anxiety sensitivity (ASI).
What is interoceptive exposure, and how does the BSQ guide it?
Interoceptive exposure involves deliberately inducing bodily sensations (e.g., spinning to create dizziness, climbing stairs to elevate heart rate) and practicing tolerance without avoidance. High BSQ scores (>50) indicate which sensations to target and confirm the need for this active exposure component. The patient learns through experience that sensations do not signal danger.
Can patients have high BSQ scores without panic attacks?
Yes. Some individuals fear bodily sensations yet do not experience full panic attacks; they may have anxiety sensitivity without the full syndrome. Conversely, others with panic attacks may score lower on BSQ because they cognitively reframe sensations or use other coping strategies. Always integrate BSQ results with panic history and functional impact.
How quickly does BSQ respond to treatment?
BSQ scores typically show modest improvement (5–10 point reduction) in the first 4 weeks of cognitive-behavioral treatment. More substantial reductions (15–25 points) usually emerge by 8–12 weeks, especially after structured interoceptive exposure practice. Faster change often predicts better long-term outcome.
