    ObjectivesThe purpose of this study was to evaluate the reliability and construct and predictive validity of the Norwegian version of the Acute Low Back Pain Screening Questionnnaire (ALBPSQ).MethodsA prospective study with a 12-month follow-up was conducted on 123 patients with acute low back pain (LBP) seeking help in primary health care for the first time and 50 patients with chronic LBP for more than 3 months.ResultsTest-retest reliability was high with intraclass correlation coefficients of 0.90, minimal detectable change of 12 points (of a total score of 210), and coefficient of variation of 4%. Internal consistency was 0.95. Principal-components analysis revealed 3 factors explaining 49% of the variance. The ALBPSQ score correlated highly (r> or =0.60) with disability variables, moderately (0.30DiscussionThe findings of this study provide further evidence of the utility of the ALBPSQ in clinical studies and in primary care settings (general practitioners, chiropractors, and physiotherapists) to help identify patients at risk of developing chronic LBP and disability.
