A psychometric investigation of fear-avoidance model measures in patients with chronic low back pain.
Validity and test-retest reliability of questionnaires related to the fear-avoidance model (FAM). ⋯ These data suggest that 4 commonly used FAM measures have similar test-retest reliability, with varying amounts of construct redundancy. The criterion validity analyses suggest that measurement of fear-avoidance constructs for patients seeking outpatient physical therapy with chronic low back pain should include the Pain Catastrophizing Scale and the FABQ.
