Factor Structure And Validation Of The German Version Of The Pain Anxiety Symptoms Scale (Pass-20)

Introduction

Pain-related anxiety plays a significant role in pain and disability, as it has been suggested as an influence on cognitive and coping responses to pain1. While avoidance behavior has often been shown as a response to pain anxiety, the question arises whether pain anxiety may also be associated with pain-related endurance, such as cognitions of thought suppression, humor/distraction, and task persistence behavior. The PASS-20 assesses cognitive, physiological and behavioral aspects of pain-related anxiety, such as cognitive anxiety, fear, physiological anxiety and escape/avoidance. The aim of this study was twofold: (1) To examine the factor structure and the psychometric characteristics of a German version of the PASS-20 in a sample of low back pain (LBP) patients, and (2) to examine aspects of criterion-related and content validity with a special focus on pain-related avoidance versus endurance.

Validity

The criterion-related validity of the PASS-20 was supported for disability as outcome variables, while pain anxiety was largely unrelated to pain. With respect to content validity, there is substantial evidence for high convergent validity (correlations with depression, fear of pain and fear-avoidance variables). Distinct relations were found for cognitive and behavioral endurance variables. The results indicate that the German version of the PASS20 is a reliable and valid measure for pain-related anxiety
