中文版儿童戒断症状评估量表在危重患儿中的信效度分析

Reliability and validity of the Chinese version of Withdrawal Assessment Tool-Version 1

目的 翻译中文版儿童戒断症状评估量表并进行信效度检验。 方法 应用 Brislin 双人翻译及回译法对量表进行文化调适，形成中文版儿童戒断症状评估量表。对 56 例患儿的 582 次测量结果进行分析，评价其信度与效度。结果 中文版 WAT鄄1 共有 11 个条目，因子分析提取 4 个公因子，累积贡献率为 57.54% 。 该量表 Cronbach＇ s α 系数为0.812 ，各因子 Cronbach＇ s α 系数为 0.701-0.942 ，组内相关系数（ intraclass correlation coefficient ， ICC ）为 0.930 。 中文版WAT鄄1 量表的内容效度为 0.910 ，各维度间的相关系数为 0.292-0.530 ，各维度与量表总分间的相关系数为 0.344-0.638 ，均具有统计学意义（ P〈0.01 ）。 ROC 曲线显示，以 WAT鄄1 总分 ≥3 分为判定戒断症状发生的临界值，特异度为 76.18% 、敏感度为 83.36% 。 结论 中文版 WAT鄄1 量表具有较好的信度和效度，且以总分 ≥3 分作为临界值，判定是否发生戒断症状，可以应用于儿童镇痛镇静药物戒断症状的评估。

Objective To translate the English version of Withdrawal Assessment Tool-Version 1 （WAT-1） into Chinese,and to test the reliability and validity of the Chinese version of WAT-1. Methods The WAT-1 was trans- lated and adapted according to Chinese culture. Totally 582 records from 56 children were used to test the relia- bility and validity of the Chinese version of WAT-1. Results The Chinese version of WAT-1 consisted of 11 items,four factors were extracted by factor analysis which could explain 57.536% of the total variance. The Cron- bach＇s α coefficient for the total scale was 0.812,and Cronbach＇s α coefficient of each factor ranged from 0.701 to 0.942. The intra-elass correlation coefficient was 0.93. The content validity index was 0.91 ,the correlation coeffi- cients among each dimension ranged from 0.292 to 0.530,and the correlation coefficient between each dimension score and total score ranged from 0.344 to 0.638. Concurrent validity was indicated by high sensitivity（83.36%） and specificity（76.18%）. Conclusion The WAT-1 showed excellent preliminary psychometric performance when used to assess clinically important withdrawal symptoms in the PICU settings.
