ASIA2000标准信度初步分析

Test-retest Reliability and Inter-rater Reliability of ASIA2000 Scale

目的测定ASIA2000标准的重测信度和评测者间一致性。方法对我院2004年4月在院的脊髓损伤患者按照入选标准筛选出25例进行信度分析,由同一检查者于第1次记录后1周使用ASIA2000标准进行再次评定,测定重测信度。同一组患者由另一名专科医师于第1次记录后24h进行检查,测定评定者间一致性。结果重测信度为,针刺觉评分、触觉评分、运动评分的Pearson相关系数均>0.90(P<0.05);残损分级和损伤完全性测定的Kappa值分别为0.787和0.756(P<0.05);评测者间一致性为,针刺觉评分、触觉评分、运动评分的Pearson相关系数均>0.85(P<0.05);残损分级和损伤完全性测定的Kappa值分别为0.802和0.764(P<0.05)。结论ASIA2000标准各项目具有较高的重测信度和评测者间一致性。

Objective To investigate the test-retest reliability and inter-rater reliability of ASIA2000 scale. Methods Twenty-five hospitalized spinal eord injury volunteers were chosen according to the selective criteria. The items were retested by the same examiner one week later to determine the scale＇s test-retest reliability. Another doctor did the same work 24 h later to determine the scale＇s inter-rater reliability. Results The Pearson eorrelation coefficients of the pin prick score, light touch score and motor score of the test-retest reliability were all above 0.90 （ P 〈0.05）, and the Kappa values of the ASIS impairment scale （AIS） and completeness of the injury were 0. 787 and 0. 756 （ P 〈0. 05）. The Pearson correlation coefficients of the pin prick score, light touch score and motor score of the inter-rater reliability were all above 0.85 （ P 〈0. 05）, and the Kappa values of the AIS and completeness of the injury were 0. 802 and 0. 764 （ P 〈0. 05）. Conclusion The ASIA2000 scale has good test-retest reliability and inter-rater reliability.
