Agoraphobia Cognitions Questionnaire (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.
