BACKGROUND
The Early Childhood Oral Health Impact Scale (ECOHIS) has recently been developed to assess oral health-related quality of life (OHRQoL) of pre-school children in English speaking communities. This study aimed to translate the ECOHIS into Farsi and test its psychometric properties for use on 2- to 5-year-old children of Farsi speaking Iranian families.
METHODS
EHOHIS questionnaire was translated into Farsi using a standardized forward-backward linguistic translation method. Its face and content validity was tested in two small pilot studies. In the main study, a convenience sample of 260 parents of 2- to 5-year-old children in Isfahan and Tehran were invited to complete the final Farsi version of the ECOHIS (F-ECOHIS) and answer two global self-rating questions about their children's dental appearance and oral health. Association between F-ECOHIS scores and answers to the two self-rating questions, and the correlation between child (9 items) and family (4 items) sections of the F-ECOHIS were used to assess the concurrent and convergent validity of the questionnaire. Internal consistency reliability of the F-ECOHIS was tested using Cronbach's alpha coefficient test and item total and inter-item correlations. One third of participants were invited to complete the F-ECOHIS again after 2 weeks to evaluate the test-retest reliability of the questionnaire.
RESULTS
Two hundred and forty six parents were included in the main study. The association between the F-ECOHIS scores and the two self-rating questions and the correlation between its child and family sections were significant (P < 0.001). Cronbach's alpha coefficient of the F-ECOHIS and its child and family sections were 0.93, 0.89, and 0.85 respectively. Coefficients did not increase by deleting any item. The corrected item total correlation coefficient ranged from 0.52 to 0.74. The inter-item correlation coefficient ranged between 0.30 and 0.73. Seventy three parents participated in the follow up study for re-testing the questionnaire. Comparison of their test and re-test scores had a weighted kappa of 0.81 and inter-class correlation (ICC) of 0.82.
CONCLUSION
The F-ECOHIS questionnaire was valid and reliable for assessing the OHRQoL of 2- to 5-year-old pre-school children of Farsi speaking parents.
背景
《幼儿口腔健康影响量表》（ECOHIS）最近已被开发出来，用于评估英语国家的学龄前儿童的口腔健康相关生活质量（OHRQoL）。本研究旨在将 ECOHIS 翻译成波斯语，并在讲波斯语的伊朗家庭的 2 至 5 岁儿童中测试其心理测量特性。
方法
使用标准化的正向-反向语言翻译方法将 EHOHIS 问卷翻译成波斯语。在两项小型试点研究中对其进行了表面和内容有效性测试。在主要研究中，邀请了 260 名伊斯法罕和德黑兰 2 至 5 岁儿童的父母完成最终的波斯语版 ECOHIS（F-ECOHIS），并回答两个关于其孩子牙齿外观和口腔健康的总体自我评估问题。F-ECOHIS 评分与两个自我评估问题的答案之间的相关性，以及 F-ECOHIS 的儿童（9 项）和家庭（4 项）部分之间的相关性，用于评估问卷的同时和收敛有效性。使用 Cronbach 的 alpha 系数测试和项目总和以及项目间相关性测试 F-ECOHIS 的内部一致性信度。邀请三分之一的参与者在 2 周后再次完成 F-ECOHIS，以评估问卷的重测信度。
结果
主要研究共纳入 246 名父母。F-ECOHIS 评分与两个自我评估问题之间的相关性以及其儿童和家庭部分之间的相关性均具有统计学意义（P <0.001）。F-ECOHIS 的 Cronbach 的 alpha 系数及其儿童和家庭部分分别为 0.93、0.89 和 0.85。删除任何项目后系数并未增加。校正后的项目总相关系数范围为 0.52 至 0.74。项目间相关性系数范围为 0.30 至 0.73。73 名父母参加了问卷的随访研究以进行重新测试。他们的测试和再测试分数的加权 Kappa 值为 0.81，组内相关系数（ICC）为 0.82。
结论
F-ECOHIS 问卷在评估讲波斯语的父母的 2 至 5 岁学龄前儿童的 OHRQoL 方面是有效且可靠的。
