听力技师对中文版耳鸣残疾量表理解情况的单中心调查

Comprehension of the Chinese Tinnitus Handicap Inventory by Audiologists: A Single Center Investigation

目的探讨中文版耳鸣残疾量表(THI-C)评估耳鸣严重程度的准确性。方法采用问卷调查的方式,对满足纳入标准的听力技师进行调查。问卷为保留了25个条目题干的THI-C。受访人员需写出对各条目的理解情况、向患者的解释内容和所使用的例子。根据华西医院听力中心培训标准,对照听力技师答案,判断听力技师对THI-C各条目的理解和解释情况。答案与培训标准不一致的均计为错误。结果共纳入技师20名,平均年龄24.95±3.41岁,男性4名,女性16名。从业时间为15±6.15月。发出调查问卷20份,回收问卷20份。听力技师对THI-C的总平均正确理解率为83.6%±19.4%,总平均正确解释率为80.6%±21.5%。亚维度的正确理解率分别为功能性88.6%、严重性87%、情感性75.6%。亚维度的正确解释率分别为功能性86.4%、严重性80%、情感性73.9%。理解和解释正确率低于90%的条目占40%。按从业时间将技师分为两组,A组:从业时间≥1年,共10名;B组:从业时间<1年,共10名。A组正确理解率、正确解释率分别为86%±17.56%、81.6%±21.35%;B组正确理解率、正确解释率分别为81.6%±22.5%、78.8%±24%。经卡方检验两组间正确理解率与正确解释率均无统计学差异(χ^2理解率=0.5,P=0.822;χ^2解释率=0.617,P=0.432)。结论经专门培训进行耳鸣咨询的我中心听力技师对THI-C的理解仍不能达到较高水平,随着从业时间的延长,正确理解率和解释率也并未明显提高。

Objective To evaluate the accuracy of the Chinese version of the Tinnitus Handicap Inventory(THIC) in assessing tinnitus severity via a questionnaire survey to audiologists. Method Audiologists training at the hearing center of West China Hospital were given a questionnaire containing only questions of the THI-C and requested to describe the scope of each item and how they would explain each item to patients. Audiologists including must satisfy the following:(1) receiving training in tinnitus assessment and consultation,(2) able to evaluate and consult patients with tinnitus independently,(3) engaged in tinnitus management for 6 months or longer, and(4) with a college degree or higher. The answers were rated as"correct"or"incorrect"according to the training center’s standard protocols and divided into two aspects: e.g. understanding and consultation. Result A total of 20 audiologists were enrolled(mean age 24.95±3.41 years, 4 men, 16 women). The overall rate of correct answers was 83.6%±19.4% for understanding and 80.6%±21.5% for consultation, respectively. For each subscale, the rate of correct answers to understanding/consultation were88.6%/86.4% for function, 87%/80% for catastrophe and 75.6%/73.9% for emotion. Rates of correct answers in understanding and explanation were lower than 90% in 40% of the subscales. According to whether the time of, we divided audiologists into two groups(Group A and Group B). Each group consisted of 10 audiologists. There were no significant differences between audiologists who had practiced for longer than 1 year(n=10) and those who had practiced for less than 1 year(n=10) in either understanding or consultation( χ^2= 0.5, P= 0.822 for understanding;χ^2= 0.617,P = 0.432 for consultation). Conclusion Comprehension of THI-C by audiologists appeared to be limited in spite of in-depth tinnitus assessment and consultation training at our center, which did not improve along with time in tinnitus consultation-related practice, probably due to innate features of the THI-C.
