title: Cultural Adaptation of the Extended Aberdeen Spine Pain Scale: A Turkish Version Study.
abstract: OBJECTIVE
  To evaluate the validity and reliability of Turkish version of Extended Aberdeen Spine Pain Scale (EASP).
  
  
  METHODS
  After cultural adaptation, the questionnaire was administered to 120 patients. Test-retest reliability, internal consistency, construct and criterion validity and responsiveness to treatment were measured. All questionnaires were administered at baseline, 1 day later and at the end of treatment. Patients were assessed with Physical and Mental Component scores of SF-36 (SF-36PCS, SF-36MCS), Beck Depression Inventory (BDI) and Visual Analog Scale for pain (VAS).
  
  
  RESULTS
  Retest scores were significant (ICC: 0.878). For internal consistency, Cronbach"s alpha was 0.908, which means all parts of the questionnaire are highly homogenous. For construct validity, Spearman"s Correlation Coefficient was 0.907, which means that items of the questionnaire behaved as expected. For criterion validity of EASP, Spearman"s rho correlations with SF- 36PCS (-0.999), SF-36MCS (-0.367), BDI (0.350), VASactivity (0.429), VASrest (0.399) and VASsleep (0.308) were found significant (p=0.000). According to responsiveness, EASP, SF-36PCS, VASactivity, VASrest, VASsleep showed significant improvement after the treatment (p=0.000).
  
  
  CONCLUSIONS
  The Turkish version of EASP seems reliable, valid, and responsive. Because of its usefulness for evaluating the whole spine as a functional unit, the EASP can be recommended for clinical trials.
