Abstract: BACKGROUND: Unvalidated Turkish adaptations of existing low back pain disability scales are often used. OBJECTIVE: To evaluate the validity and the reliability of the Turkish version of Aberdeen Low Back Pain Scale (ALBP). METHODS: The cross-cultural adaptation was performed in accordance with recently published guidelines. The Turkish version was administered to 120 patients. Test-retest and internal consistency were evaluated for reliability. Construct validity and criterion validity were measured. Responsiveness of the questionnaire towards changes by the treatment were assessed. All questionnaires were administered at admission, 1 day later, at the end of treatment, and a month after the end of treatment. Patients were assessed with Ostwestry (OLBP), physical and mental component of SF-36 (PCSSF-36, MCSSF-36), Beck Depression Inventory (BDI), Schober test and visual analog scale for pain (VAS). RESULTS: Retest scores were significant and high (Internal Correlation Coefficent: 0.963). For internal consistency, Cronbach's alpha was 0.889. For construct validity, Spearman's Correlation Coefficent was 0.882. For criterion validity of ALBP, correlations were found significant and acceptable for OLBP, PCSSF-36, MCSSF-36, BDI, and VASactivity (p < 0.05). According to responsiveness; ALBP, OLBP, PCSSF-36, VAS and Schober test showed significant improvement after the treatment (p < 0.05). CONCLUSIONS: The Turkish version of the ALBP is reliable, valid and responsive.
