Adaptation and validation of the chronic otitis media questionnaire 12 (COMQ-12) in the Mexican Spanish language (COMQ-12-Mx)

Abstract

Background: Chronic otitis media (COM) questionnaire 12 (COMQ-12) is a specific-disease tool that evaluates COM patients.

Objective: To validate COMQ-12 in the Mexican Spanish language (COMQ-12-Mx).

Materials and methods: Mexican Spanish-speaking healthy volunteers and COM patients who attended a Secondary Care Center from May 2019 to October 2019. The COMQ-12 in Mexican Spanish was obtained by translation and back translation from an English-Spanish translator. All participants completed the COMQ-12-Mx questionnaire. COM patients were included regardless of their COM status. Control group completed the questionnaire twice. Participants were categorized into three groups: group 1 (COM), group 2 (volunteers first test) and group 3 (volunteers retest). Cronbach’s alpha was used for internal consistency, Spearman’s rank correlation coefficient was used for test-retest reliability and Mann–Whitney U test compared groups.

Results: We included 78 Mexican Spanish-speaking participants (COM n = 37, healthy volunteers n = 41), 51 females and 27 males, mean age was 39.67 years (SD ± 18.32). Group 1 COMQ-12-Mx score was 22.108 ± 11.79, group 2 score was 3.561 ± 4.399 (p ≤ .001) and group 3 score was 3.683 ± 4.435. Cronbach’s alpha was 0.828 and test-retest reliability achieved a 0.928 outcome.

Conclusions: COMQ-12-Mx is a valid and reliable tool to evaluate quality life in Mexican Spanish-speaking patients with COM.

背景：慢性中耳炎（COM）问卷12（COMQ-12）是一种评价慢性中耳炎患者的特异性疾病工具。

目的：验证墨西哥西班牙语（COMQ-12-Mx）的COMQ-12。

材料和方法：2019年5月至2019年10月在二级护理中心就诊的墨西哥西班牙语健康志愿者和COM患者。墨西哥西班牙语的COMQ-12是由一名英语-西班牙语翻译人员翻译后产生的。所有参与者填写了COMQ-12-Mx问卷。无论患者的COM状态如何, 均纳入其中。对照组完成两次问卷调查。参与者分为三组：第一组（COM）、第二组（志愿者第一次测试）和第三组（志愿者再次测试）。内部一致性采用Cronbach's alpha, 重测可信度采用Spearman秩相关系数, Mann-Whitney U检验比较组。

结果：78名墨西哥西班牙语参与者（COM n=37, 健康志愿者n=41）, 51名女性, 27名男性, 平均年龄39.67岁（SD±18.32）。第一组COMQ-12-Mx评分为22.108±11.79, 第二组为3.561±4.399（p≤.001）, 第三组为3.683±4.435。Cronbach'sα为0.828, 重测可信度为0.928。

结论：COMQ-12-Mx是评价墨西哥西班牙语患者COM生活质量的有效、可靠的工具。
