Abstract

BACKGROUND

Early childhood caries (ECC) is prevalent in Thailand, but no appropriate tool has been available to measure its impact on children's quality of life. This study translated the Early Childhood Oral Health Impact Scale (ECOHIS), a widely used proxy-reported questionnaire developed in the United States for measuring the oral health-related quality of life of preschool children and their families, into Thai (Th-ECOHIS). The scale's psychometric properties were investigated in Thai caregivers and their children.

METHODS

Cultural adaptation for the scale development within the Thai context was processed using forward-backward translation by experts. A face and content validation was conducted among 20 Thai caregivers to attain the final Th-ECOHIS. Psychometric testing was done on 3-year-old child-caregiver pairs in Bangkok using the interviewer-administered mode. Children's oral health was determined by caries experience (decayed, missing and filled primary teeth, dmft) and treatment need. The caregivers answered the Th-ECOHIS and global questions regarding their perception of the children's oral health. Across-items reliability was assessed by internal consistency using the Cronbach's alpha coefficient. Test-retest reliability was managed at a 2-week interval in 10% of the sample using the intraclass correlation coefficient calculated by two-way analysis of variance. The discriminant validity was tested by the relationship between the severity of dental caries, treatment need and Th-ECOHIS scores, using the Kruskal-Wallis test.

RESULTS

A total of 214 child-caregiver pairs participated. Twenty-two percent had ECC (dmft 1-3) and 17.3% had severe ECC (dmft 4 or higher) with mean (SD) dmft 1.63 (2.92). All items in the original ECOHIS were retained in the Thai version. The test-retest reliability of Th-ECOHIS was 0.87; internal consistency was 0.85; the total Th-ECOHIS scores were significantly correlated with the global rating of oral health question (r = 0.604). Th-ECOHIS scores in both child and family impact sections and the total were significantly associated with the severity of caries (p < 0.001) and treatment need (p < 0.001).

CONCLUSIONS

Th-ECOHIS demonstrated good reliability and validity. It could be used on caregivers to assess the impacts of ECC on quality of life of Thai pre-school children and compared to other countries.

摘要

背景

儿童龋病（ECC）在泰国很普遍，但一直没有合适的工具来衡量其对儿童生活质量的影响。本研究将美国广泛使用的儿童口腔健康影响量表（ECOHIS）翻译成泰语（Th-ECOHIS），该量表是一种用于衡量学龄前儿童及其家庭口腔健康相关生活质量的代理报告问卷。在泰国看护者及其子女中对该量表的心理测量学特性进行了研究。

方法

在泰国背景下，通过专家进行正向和反向翻译对量表进行文化适应性改编。对 20 名泰国看护者进行了表面和内容验证，以获得最终的 Th-ECOHIS。在曼谷，通过访谈者管理的模式对 3 岁的儿童-看护者对进行心理测量测试。通过龋齿经历（龋齿、缺失和填充的乳牙，dmft）和治疗需要来确定儿童的口腔健康。看护者回答了 Th-ECOHIS 和关于他们对儿童口腔健康的看法的总体问题。使用 Cronbach 的 alpha 系数评估跨项目的内部一致性来评估整个量表的信度。在 10%的样本中，通过双向方差分析的组内相关系数计算，在两周的间隔内进行了重测信度管理。通过 Kruskal-Wallis 检验，通过与严重程度的关系来检验区分效度龋齿、治疗需要和 Th-ECOHIS 评分。

结果

共有 214 对儿童-看护者参与了研究。22%的儿童有 ECC（dmft 1-3），17.3%的儿童有严重的 ECC（dmft 4 或更高），平均（SD）dmft 为 1.63（2.92）。原始 ECOHIS 中的所有项目都保留在泰语版本中。Th-ECOHIS 的重测信度为 0.87；内部一致性为 0.85；总 Th-ECOHIS 评分与口腔健康总体评分问题呈显著相关（r=0.604）。儿童和家庭影响部分以及总评分的 Th-ECOHIS 评分与龋齿的严重程度（p<0.001）和治疗需要（p<0.001）显著相关。
