The International Outcome Inventory for Hearing Aids (IOI-HA) is a seven-item hearing-specific questionnaire. It was developed with the purpose of evaluating the efficacy of hearing aid rehabilitation. Few psychometric properties have been presented for a Swedish translation of the IOI-HA. Furthermore, previous studies have examined the IOI-HA in mainly sensorineural hearing losses, and we do not know how the type of hearing loss affects the outcome.
To evaluate the hearing aid fitting outcome measured in a clinical setting using a Swedish translation of the International Outcome Inventory for Hearing Aids (IOI-HA), to determine the psychometric properties of the translation, and to examine how a number of demographic variables such as type of hearing loss affect the outcome.
A descriptive and correlational study in a retrospective sample.
Two hundred and twenty-four (107 females and 117 males; ages 27-94 yr with an average of 66.1 yr) first-time hearing aid users.
Mostly digital hearing aids (97.8%) were fitted monaurally (60%) or binaurally (40%) between 2007 and 2009.
The subjects were mailed the IOI-HA questionnaire six months after their final appointment, and the completed questionnaire was returned by mail to the clinic. The psychometric properties were evaluated and compared to previous studies using the IOI-HA. The associations between the outcome scores and a number of demographic variables (age, gender, degree of hearing loss, type of hearing loss, number of hearing aids, and type of hearing aids) were examined. Based on the pure tone audiograms, the subjects were divided into three groups; those with conductive hearing losses, sensorineural hearing losses, and mixed hearing losses. For these groups, the differences in outcome measured as IOI-HA were examined.
The psychometric properties of the present translation of the IOI-HA showed resemblance in many aspects to previous reports. Furthermore, the type of hearing loss seems to affect the IOI-HA outcome. Hearing loss increases with increasing age, and hearing aid use increases with increasing degree of hearing loss. Subjects with sensorineural hearing losses show significantly poorer scores on items concerning introspective aspects of the outcome in comparison to subjects with mixed hearing losses and subjects with conductive hearing losses. Monaurally fitted subjects tend to report lower scores on average, but monaural or binaural hearing aid fitting do not significantly affect the subjective outcome.
The psychometric properties of the present Swedish translation of the IOI-HA show resemblance in many aspects to previous reports, but the differences observed could be due to differences in the study populations. Overall, the demographic variables examined could not be used as predictors for the hearing aid fitting outcome, and more reliable predictors need to be identified.
国际助听器效果量表（IOI-HA）是一份包含七个项目的听力专项调查问卷。其编制目的是评估助听器康复效果。目前关于IOI-HA瑞典语译本的心理测量学特性研究较少。此外，以往研究主要针对感音神经性听力损失人群对IOI-HA进行了考察，而我们并不清楚听力损失类型如何影响结果。
使用国际助听器效果量表（IOI-HA）的瑞典语译本评估临床环境下的助听器验配效果，确定该译本的心理测量学特性，并考察一些人口统计学变量（如听力损失类型）如何影响结果。
对回顾性样本进行描述性和相关性研究。
224名首次使用助听器的用户（107名女性和117名男性；年龄27 - 94岁，平均66.1岁）。
2007年至2009年间，大多数（97.8%）用户佩戴的是数字助听器，单耳佩戴比例为60%，双耳佩戴比例为40%。
在受试者最后一次就诊六个月后，通过邮件向他们发放IOI-HA问卷，完成的问卷通过邮件返回诊所。评估心理测量学特性，并与以往使用IOI-HA的研究进行比较。考察结果得分与一些人口统计学变量（年龄、性别、听力损失程度、听力损失类型、助听器数量和助听器类型）之间的关联。根据纯音听力图，将受试者分为三组：传导性听力损失组、感音神经性听力损失组和混合性听力损失组。针对这些组，考察以IOI-HA衡量的结果差异。
目前IOI-HA瑞典语译本的心理测量学特性在许多方面与以往报告相似。此外，听力损失类型似乎会影响IOI-HA结果。听力损失随年龄增长而增加，助听器使用随听力损失程度增加而增加。与混合性听力损失受试者和传导性听力损失受试者相比，感音神经性听力损失受试者在结果内省方面的项目得分明显更低。单耳佩戴的受试者平均得分往往较低，但单耳或双耳佩戴助听器对主观结果没有显著影响。
目前IOI-HA瑞典语译本的心理测量学特性在许多方面与以往报告相似，但观察到的差异可能归因于研究人群的不同。总体而言，所考察的人口统计学变量不能用作助听器验配结果的预测指标，需要确定更可靠的预测指标。
