Abstract

Objective: Linguistic and psychometric validation of the French version of the COSI questionnaire (Client-Oriented Scale of Improvement) assessing perceived improvement with hearing aids.

Methods: A single-center prospective study was conducted in 100 patients with hearing aids (NCT06108609). They filled out the COSI and IOI-HA questionnaires (International Outcome Inventory for Hearing Aids). COSI is a free-choice questionnaire in which the respondent chooses 5 out of 16 items corresponding to the main auditory problems. Psychometric analysis followed the COSMIN guidelines. Test-retest reliability was assessed on intra-class correlation coefficient (ICC) in 36 patients. Correlations between COSI subscores and between COSI and global IOI-HA score were assessed.

Results: Median COSI subscores were 3.8 [IQR: 3.2-4.2] for "degree of change" and 3.6 [IQR: 3.0-4.2] for "final ability". Internal consistency was good, with Cronbach alpha 0.76 and 0.79 respectively. ICC was 0.68 (95% CI: 0.45-0.82) for "degree of change" and 0.81 (95% CI: 0.66-0.90) for "final ability". There was a strong correlation between the 2 subscores: r=0.73 (95% CI: 0.62-0.81); P<0.001 There were moderate positive correlations between COSI and IOI-HA scores: r=0.59 and r=0.63; P<0.001.

Conclusion: The French version of the COSI questionnaire showed satisfactory psychometric properties. Its reliability, internal consistency and clinical relevance are sufficient for inclusion in everyday practice for personalized evaluation of hearing aids.

面向客户的改进量表（COSI）问卷的法语翻译与心理测量学验证。

目的：对法语版COSI问卷（以客户为导向的改善量表）进行语言和心理测量学验证，以评估助听器的感知改善。方法：对100例助听器患者（NCT06108609）进行单中心前瞻性研究。他们填写了COSI和IOI-HA问卷（国际助听器结果清单）。COSI是一种自由选择问卷，被调查者从16个项目中选择5个与主要听觉问题相对应的项目。心理测量分析遵循COSMIN指南。用类内相关系数（ICC）评估36例患者的重测信度。评估COSI评分之间以及COSI与整体IOI-HA评分之间的相关性。结果：“变化程度”COSI分值中位数为3.8 [IQR: 3.2-4.2]，“最终能力”COSI分值中位数为3.6 [IQR: 3.0-4.2]。内部一致性较好，Cronbach alpha分别为0.76和0.79。“变化程度”的ICC为0.68 (95% CI: 0.45-0.82)，“最终能力”的ICC为0.81 （95% CI: 0.66-0.90）。两个亚评分之间有很强的相关性：r=0.73 (95% CI: 0.62-0.81)；结论：法语版COSI问卷具有满意的心理测量特性。其可靠性、内部一致性和临床相关性足以在日常实践中纳入助听器的个性化评估。

期刊介绍： European Annals of Oto-rhino-laryngology, Head and Neck diseases heir of one of the oldest otorhinolaryngology journals in Europe is the official organ of the French Society of Otorhinolaryngology (SFORL) and the the International Francophone Society of Otorhinolaryngology (SIFORL). Today six annual issues provide original peer reviewed clinical and research articles, epidemiological studies, new methodological clinical approaches and review articles giving most up-to-date insights in all areas of otology, laryngology rhinology, head and neck surgery. The European Annals also publish the SFORL guidelines and recommendations.The journal is a unique two-armed publication: the European Annals (ANORL) is an English language well referenced online journal (e-only) whereas the Annales Françaises d’ORL (AFORL), mail-order paper and online edition in French language are aimed at the French-speaking community. French language teams must submit their articles in French to the AFORL site. Federating journal in its field, the European Annals has an Editorial board of experts with international reputation that allow to make an important contribution to communication on new research data and clinical practice by publishing high-quality articles.
