Pain Anxiety Symptoms Scale
The Pain Anxiety Symptoms Scale (PASS) is a 20-item self-report instrument developed by Asmundson and colleagues in 1996 to measure anxiety symptoms specifically related to pain. The PASS captures fear of pain, avoidance behaviors, cognitive anxiety, and physiological anxiety responses that commonly accompany chronic pain and contribute to disability through fear-avoidance mechanisms.
