The objective of this study was to adapt the Oral Health-related Early Childhood Quality of Life (OH-ECQoL) tool for the Malayalam-speaking community and investigate its validity and reliability.
Malayalam language version of OH-ECQoL was derived through a forward-backward translation and tested for content validity. A convenient sample (n = 300) was recruited by including children with and without early childhood caries (ECC). Parents of these children completed the derived Malayalam OH-ECQoL measure. The properties of translated OH-ECQoL were evaluated by determining its validity and reliability using concurrent validity, construct validity, discriminant validity, internal consistency, and test-retest reliability.
OH-ECQoL scores varied with ECC and caries-free groups (P < 0.001), supporting the ability to distinguish between patient groups. Discriminant validity tests show that children with ECC have greater median scores and interquartile range (21 ± 8) compared to children without ECC (14 ± 2). Concurrent validity was observed to be 0.72 and 0.71, respectively, for child section (P < 0.001). Convergent validity demonstrates a strong positive correlation between child impact and family impact with a Spearman's correlation coefficient significant of 0.73 (P ≤ 0.01). Cronbach's alpha for the child impact section and family impact section showed good internal consistency at 0.92 and 0.83, respectively. Test-retest reliability at 0.87 shows good reliability.
The Malayalam version of the OH-ECQoL tool demonstrated acceptable validity and reliability. The study also shows that ECC presents a negative impact on the QoL of preschool children and their parents.
本研究的目的是使口腔健康相关的幼儿生活质量（OH-ECQoL）工具适用于说马拉雅拉姆语的社区，并调查其有效性和可靠性。
OH-ECQoL的马拉雅拉姆语版本通过正向-反向翻译得出，并进行了内容效度测试。通过纳入有和没有幼儿龋齿（ECC）的儿童招募了一个便利样本（n = 300）。这些儿童的父母完成了衍生的马拉雅拉姆语OH-ECQoL测量。通过使用同时效度、结构效度、区分效度、内部一致性和重测信度来确定其有效性和可靠性，从而评估翻译后的OH-ECQoL的特性。
OH-ECQoL得分在ECC组和无龋组之间存在差异（P < 0.001），支持区分患者组的能力。区分效度测试表明，与无ECC的儿童（14±2）相比，患有ECC的儿童的中位数得分和四分位间距更大（21±8）。儿童部分的同时效度分别为0.72和0.71（P < 0.001）。收敛效度表明儿童影响和家庭影响之间存在强正相关，斯皮尔曼相关系数为0.73（P≤0.01），具有显著性。儿童影响部分和家庭影响部分的克朗巴哈系数分别为0.92和0.83，显示出良好的内部一致性。重测信度为0.87，显示出良好的信度。
OH-ECQoL工具的马拉雅拉姆语版本表现出可接受的有效性和可靠性。该研究还表明，ECC对学龄前儿童及其父母的生活质量有负面影响。
