概要	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.	The Pain Catastrophizing Scale (PCS) is a 13-item self-report questionnaire developed by Sullivan, Bishop, and Pivik in 1995 to measure catastrophic thinking about pain—the tendency to magnify pain threat, ruminate about pain, and feel helpless in response to pain. Elevated catastrophizing predicts worse pain outcomes and is a key treatment target in cognitive-behavioral pain management.
