This study aims to cross-culturally adapt the original English-language COHIP-SF 19 to Arabic culture and to test its psychometric properties in a community sample.
The Arabic COHIP-SF 19 was developed and its psychometric properties were examined in a population-based sample of 876 schoolchildren who were aged 12 years of age, in Benghazi, Libya. The Arabic COHIP-SF 19 was tested for its internal consistency, reproducibility, construct validity, factorial validity and floor as well as ceiling effects. A Mann-Whitney U test was used to compare the mean scores of COHIP-SF 19 by participants' caries status and self-reported oral health rating, satisfaction and treatment need.
The Arabic COHIP-SF 19 was successfully and smoothly developed. It showed an acceptable level of equivalence to the original version. Overall, the internal consistency and reproducibility were acceptable to excellent, with a Cronbach's alpha of 0.84 and an intra-class correlation coefficient (ICC) of 0.76. All hypotheses predefined to test construct validity were confirmed. That is, children who had active dental caries, and who rated their oral health as poor, were not satisfied with their oral health or indicated the need of treatment had lower COHIP-SF 19 scores (P < 0.05). Floor or ceiling effects were not observed. The exploratory Factorial analysis suggested a 4-component solution and deletion of one item.
The Arabic COHIP-SF 19 was successfully developed. The measure demonstrated satisfactory reliability and validity to estimate OHRQoL in a representative sample of 12-year-old schoolchildren.
本研究旨在将原始英文版本的儿童口腔健康影响概况简表（COHIP-SF）19进行跨文化改编，使其适用于阿拉伯文化，并在社区样本中测试其心理测量特性。
开发了阿拉伯语版的COHIP-SF 19，并在利比亚班加西的876名12岁学童的基于人群的样本中检查其心理测量特性。对阿拉伯语版的COHIP-SF 19进行了内部一致性、可重复性、结构效度、因子效度以及地板效应和天花板效应的测试。使用曼-惠特尼U检验比较参与者的龋齿状况、自我报告的口腔健康评级、满意度和治疗需求下的COHIP-SF 19平均得分。
阿拉伯语版的COHIP-SF 19成功且顺利地开发出来。它与原始版本显示出可接受的等效水平。总体而言，内部一致性和可重复性从可接受至优秀，克朗巴哈系数为0.84，组内相关系数（ICC）为0.76。所有预先定义用于测试结构效度的假设均得到证实。即，患有活动性龋齿、将其口腔健康评为差、对口腔健康不满意或表示需要治疗的儿童的COHIP-SF 19得分较低（P < 0.05）。未观察到地板效应或天花板效应。探索性因子分析建议采用四成分解决方案并删除一个项目。
阿拉伯语版的COHIP-SF 19成功开发。该测量方法在12岁学童的代表性样本中显示出令人满意的数据可靠性和有效性，可用于评估口腔健康相关生活质量（OHRQoL）。
