The chronic ear survey (CES) is a sensitive and disease specific quality of life (QoL) measurement tool in patients with chronic suppurative otitis media (CSOM). It is a 13-item survey that evaluates the frequency, duration and severity of problems associated with this disease. It is composed of three subscales that describe activity restrictions, symptoms and medical resource utilisation. Based on patient's answers, it is possible to obtain a score resulting in a scale ranging from 0 to 100; the highest indicates the best health, while the lowest denotes poor health. The questionnaire was originally created in English. The aim of this study is to validate the CES questionnaire in Italian (CES-I). Translation was made following international guidelines. The application follows the stages of translation from English to Italian and linguistic adaptation, and grammatical and idiomatic equivalence review. The CES-I and the Short Form Health Survey 36 (SF-36) questionnaires were administered to 54 patients with CSOM. A cross-sectional design was used to examine the internal consistency (Cronbach's alpha) and concurrent validity (Pearson's product moment correlation). To confirm the external validity of CES-I, Pearson correlation coefficient, considering the total score and single subscales of CES and the 8 scales of the SF-36, was calculated. Cronbach's alpha coefficient for internal consistency was 0.737. The intraclass correlation coefficient, measured through mixed effects, was 0.737 (95% CI: 0.600-0.835, p < 0.001) for average measures and 0.412 (95%CI: 0.273-0.559, p < 0.001) for individual measures. According to our results, CES-I is a reliable tool for evaluation of QoL in patients with CSOM among the Italian-speaking population.
慢性耳部调查（CES）是一种针对慢性化脓性中耳炎（CSOM）患者的敏感且具有疾病特异性的生活质量（QoL）测量工具。它是一项包含13个条目的调查，用于评估与该疾病相关问题的发生频率、持续时间和严重程度。它由三个子量表组成，分别描述活动受限、症状和医疗资源利用情况。根据患者的回答，可以得到一个0至100分的分数；分数越高表明健康状况越好，分数越低则表示健康状况不佳。该问卷最初以英文编制。本研究的目的是验证意大利语版的CES问卷（CES-I）。翻译遵循国际指南进行。应用过程包括从英文到意大利文的翻译、语言调整以及语法和习语等效性审查。CES-I和简短健康调查36项问卷（SF-36）被发放给54名CSOM患者。采用横断面设计来检验内部一致性（Cronbach's alpha）和同时效度（Pearson积差相关）。为了确认CES-I的外部效度，计算了考虑CES总分和单个子量表以及SF-36的8个量表之间的Pearson相关系数。内部一致性的Cronbach's alpha系数为0.737。通过混合效应测量的组内相关系数，平均测量值为0.737（95%可信区间：0.600 - 0.835，p < 0.001），个体测量值为0.412（95%可信区间：0.273 - 0.559，p < 0.001）。根据我们的结果，CES-I是评估意大利语人群中CSOM患者生活质量的可靠工具。
