Agoraphobia Cognitions Questionnaire (ACQ)
Also known as: ACQ
The Agoraphobia Cognitions Questionnaire (ACQ) is a 14-item self-report instrument that assesses catastrophic and safety-related thoughts in individuals with agoraphobia and panic disorder. Developed by Chambless and colleagues in 1984, it measures two domains: fear of loss of control and worry about social consequences. The ACQ is a cornerstone measure in clinical research and practice for understanding the cognitive mechanisms that maintain agoraphobic avoidance and panic-related anxiety.

When to use it
The ACQ is indicated for clinical assessment of agoraphobia, panic disorder, and social anxiety disorder. It is useful in pre-treatment evaluation to understand cognitive drivers of avoidance, monitoring treatment response (cognitive-behavioral therapy, exposure therapy), and research examining catastrophic cognition in anxiety pathology. Appropriate for adolescents and adults; less suitable for children under 12 or those with severe cognitive impairment.
Strengths & limitations
- Two-factor structure directly targets agoraphobic cognitions: loss of control and social consequences, allowing treatment to be calibrated to specific fears.
- Strong psychometric properties: internal consistency (Cronbach's α = 0.80–0.88) and established convergent/discriminant validity with other anxiety measures.
- Sensitive to cognitive-behavioral interventions; reductions in ACQ scores predict improvement in avoidance behavior and panic frequency.
- Brief (14 items) and quick to administer; suitable for repeated measurement during treatment.
- Cross-culturally validated in multiple languages and populations with replicable factor structure.
- Focused exclusively on cognitions; does not assess behavioral avoidance, physiological symptoms, or subjective panic intensity.
- Does not distinguish between realistic and unrealistic threat appraisals—all catastrophic thoughts are weighted equally.
- Modest test–retest reliability (r = 0.68–0.75) over 2–4 weeks suggests fluctuation in catastrophic thinking.
- Less specific to agoraphobia alone; elevated scores occur in any anxiety or trauma condition with threat appraisal.
Frequently asked
What is the difference between Loss of Control and Social Consequences on the ACQ?
Loss of Control items capture internal fears—fainting, collapsing, losing one's mind, or dying. Social Consequences items reflect external social judgment—people thinking you are crazy or weak. Treatment may emphasize interoceptive exposure and behavioral experiments for Loss of Control and social exposure and values-based work for Social Consequences.
Can high ACQ scores exist without agoraphobic avoidance?
Yes. Some individuals have catastrophic thoughts but do not avoid situations (e.g., anxious but courageous people). Conversely, others avoid without endorsing catastrophic cognitions (e.g., conditioned avoidance). ACQ measures cognition; behavioral assessment (e.g., avoidance patterns, functional impairment) is essential for diagnosis and treatment.
How quickly does the ACQ respond to cognitive-behavioral treatment?
ACQ scores often decline within 4–8 weeks of cognitive restructuring and exposure therapy. Early drops (first 2–4 weeks) correlate with cognitive change; sustained reductions (8+ weeks) typically accompany avoidance reduction and panic symptom improvement.
Is the ACQ useful in social anxiety disorder or generalized anxiety disorder?
The ACQ is less specific to social anxiety or GAD than to agoraphobia/panic. However, elevated ACQ scores can occur in any anxiety disorder with threat-focused thoughts. Always integrate ACQ results with disorder-specific measures (e.g., SPAI for social anxiety, PSWQ for GAD) for accurate case conceptualization.
