中文译本耳鸣致残量表的临床应用研究

The clinical application of tinnitus handicap index(THI-12) Chinese version

目的:对中文译本耳鸣致残量表(THI-12)进行临床应用研究,探索一种使用方便的耳鸣严重程度评估工具。方法:对229例以原发性耳鸣为主诉的门诊初诊患者进行问卷调查,问卷内容包括中文译本THI-12评分和标准版THI-25评分,比较2种评分耗时,对2种评分总分进行相关性分析,比较2种评分对耳鸣严重程度的评级,对中文译本THI-12进行可靠性和因子分析。结果:229份问卷中,合格215份,应答率为93.9%。完成THI问卷平均耗时(18.9±21.0)min,完成THI-12平均耗时(8.96±4.70)min,两者比较差异有统计学意义。两者总评分Pearson′s相关系数r=0.833(P<0.01),两者总评分呈极强正相关,2种评估方法对耳鸣严重程度评级差异无统计学意义(Z=-0.283,P>0.05)。THI-12问卷可信度Cronbach′s系数α=0.765,说明问卷内部一致性信度较好。因子分析显示3个条目特征值>1,提取3个公共因子,其累计方差贡献率为51.77%,提示量表12个条目可分为3个维度(情感性、社会性、注意力)。各条目共同度分析中"耳鸣令你注意力难以集中"的共同值最高(0.78),提示该条目在整个量表中分3个维度时贡献最大。结论:中文译本THI-12耗时少,可信度和内部结构效度较高,能较好地评估耳鸣严重程度,可在临床上广泛应用。

Objective：The original prospective of this study is to explore a convenient tinnitus severity assessment tool,using Chinese version of THI-12.Method：We surveyed 229 outpatients on their first hospital visits with primary tinnitus as chief complaint.Both the Chinese version THI-12 and the standard THI-25 were administrated.Their tinnitus grading and administration time were compared.The correlation between the two scores was evaluated.A reliability and factor analysis of the Chinese version of THI-12 was also performed.Result：Two hundred and fifteen of the 229 questionnaires were valid with a 93.9%response rate.The average administration time was（18.9±21.0）min for the standard THI-25and（8.96±4.70）min for the Chinese version THI-12,which was significantly different.Pearson′s correlation coefficient between the two total scores was r=0.833（P〈0.01）,which indicates a strong positive correlation.The tinnitus grading was not statistically significant（Z=-0.307,P〉0.05）.Cronbach′s coefficient of THI-12wasα=0.765,suggesting good reliability and internal consistency.Factor analysis found three entries with characteristic values greater than 1.These three common factors explained51.77% of the overall variance,suggesting that the 12 entries can be grouped into three dimensions（emotionality,sociality,concentration）.Entry ＂ Because of your tinnitus is it difficult for you to concentrate？＂ had the highest common value（0.78）,suggesting that this entry would contribute the most should all entries be divided into three dimensions.Conclusion：The Chinese version THI-12 is time-efficient,has good reliability and internal structural validity,and provides good assessment of tinnitus severity.It can be widely applied in clinical practice.
