A Short Version of the Pain Anxiety Symptoms Scale (PASS‐20): Preliminary Development and Validity

Research has shown significant relations between fear and avoidance of pain and the suffering and disability of chronic pain. Effective measurement tools have formed the foundation for studying these relations.

The present article describes the initial development and validation of the PASS-20, a short form version of the Pain Anxiety Symptoms Scale (PASS). Like the original inventory, the PASS-20 measures fear and anxiety responses specific to pain. Items were selected for the short version based on item variance, item intercorrelation and reliability analyses.
