Test-retest reliability of the Örebro Musculoskeletal Pain Screening Questionnaire and the Situational Pain Scale in patients with chronic low back pain.

Objective: To determine the test-retest reliability of the Örebro Musculoskeletal Pain Screening Questionnaire (OMPSQ) and of the Situational Pain Scale (SPS) in patients with chronic low back pain (CLBP).

Methods: CLBP patients (n = 30) who were capable of reading French completed the OMPSQ and the SPS twice with a 1-week interval in one rehabilitation centre in French-speaking Switzerland. To study the test-retest reliability, we calculated intraclass correlation coefficients (ICCs) for the reliability of the overall scores of the two questionnaires.
