ASIA2000标准信度初步分析

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〈00．05）；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。

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

ObjectiveTo investigate the test-retest reliability and inter-rater reliability of ASIA2000 scale.MethodsTwenty-five hospitalized spinal cord 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.ResultsThe Pearson correlation 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).ConclusionThe ASIA2000 scale has good test-retest reliability and inter-rater reliability.
