Anxiety Sensitivity Index–3 (ASI-3)
Also known as: ASI-3
The Anxiety Sensitivity Index–3 (ASI-3) is an 18-item self-report questionnaire that measures anxiety sensitivity—the tendency to fear bodily sensations and interpret them as signs of impending threat. Developed by Taylor and colleagues in 2007, it distinguishes between three domains of anxiety sensitivity: physical, cognitive, and social. The ASI-3 is widely used in research and clinical assessment to identify individuals at risk for anxiety disorders, panic disorder, and post-traumatic stress.

When to use it
The ASI-3 is indicated for screening anxiety sensitivity in adolescents and adults across diverse populations (clinical, community, university). It is especially useful in pre-treatment assessment for anxiety, panic, or trauma-related disorders; monitoring treatment response in cognitive-behavioral therapy (CBT); and identifying cognitive vulnerabilities in prevention programs. It is not appropriate for children under 12 or individuals with severe cognitive impairment.
Strengths & limitations
- Three-factor structure (physical, cognitive, social) provides nuanced assessment beyond global anxiety.
- Robust psychometric properties: high internal consistency (Cronbach's α = 0.88–0.92 total scale) and strong convergent/discriminant validity.
- Strong predictor of anxiety disorders, panic, and trauma-related pathology; sensitive to treatment effects.
- Brief (18 items) and easy to administer; suitable for repeated measurement in clinical monitoring.
- Clinically useful domains identify which facet of anxiety sensitivity drives a patient's fear response.
- Relies on self-perception; individuals may not accurately recognize or report their fear of bodily sensations.
- Does not assess behavioral avoidance—only cognitive/emotional fear response.
- Modest predictive power for specific phobias relative to generalized anxiety.
- Two-week test–retest reliability (r = 0.79) suggests some fluctuation, necessitating repeated measures in volatile clinical states.
Frequently asked
How does anxiety sensitivity differ from trait anxiety?
Anxiety sensitivity is fear of the sensations caused by anxiety (meta-anxiety), while trait anxiety is the general tendency to experience worry and nervousness. A person can be high in trait anxiety but low in anxiety sensitivity (they worry but do not fear their worry). Conversely, low-trait individuals with high sensitivity may panic when they experience isolated physical symptoms.
What is a clinical cutoff score on the ASI-3?
There is no universal diagnostic cutoff; rather, scores are interpreted as a continuous risk gradient. Scores 50–72 are associated with elevated risk for anxiety and panic disorders and often trigger intervention. In treatment contexts, reductions of 10–15 points are considered clinically meaningful.
Can the ASI-3 be used in non-English-speaking populations?
Yes. The ASI-3 has been translated and validated in 15+ languages, including Spanish, German, French, Dutch, and Portuguese. Always consult the published validation study for the target language before use.
Is the ASI-3 suitable for monitoring treatment progress?
Yes. ASI-3 is sensitive to cognitive-behavioral interventions for anxiety and panic. Clinicians often re-administer every 4–8 weeks during treatment. Reductions correlate with symptom improvement and predict sustained recovery.
How does the three-factor structure inform treatment?
Physical Concern may warrant interoceptive exposure (breathing exercises, exercise). Cognitive Concern often benefits from cognitive restructuring and thought records. Social Concern may require social anxiety interventions and exposure in social settings.
