This study aimed to develop and validate the Malocclusion Impact Scale for Early Childhood (MIS-EC), a malocclusion-specific measure of oral health-related quality of life (OHRQoL) of children aged 3-5 years and their parents/caregivers. A pool of items was analysed to identify those relevant to the assessment of the impact of malocclusion on OHRQoL. Dental professionals and mothers of children with and without malocclusion rated the importance of these items. The final version of the MIS-EC was evaluated in a cross-sectional study comprising 381 parents of children aged 3-5 years to assess construct validity, internal consistency and test-retest reliability. Twenty-two items were identified from item pooling. After item reduction, eight items were chosen to constitute the MIS-EC, in addition to two general questions. The MIS-EC demonstrated good internal consistency (Cronbach's alpha = 0.79 for the Child Impact section and 0.53 for the Family Impact section), and excellent test-retest reliability (ICC = 0.94), floor effect was 55.7% and ceiling effect 0%. MIS-EC scores indicating worse OHRQoL were significantly associated with the presence of malocclusion (p < 0.05). The MIS-EC is reliable and valid for assessing the impact of malocclusion on the OHRQoL of preschool children and their parents/caregivers.
本研究旨在开发和验证儿童早期错畸形影响量表（MIS-EC），这是一种专门用于评估 3-5 岁儿童及其父母/照顾者口腔健康相关生活质量（OHRQoL）的错畸形特异性量表。分析了一组项目，以确定那些与错畸形对 OHRQoL 影响评估相关的项目。口腔专业人员和有或没有错畸形的儿童的母亲对这些项目的重要性进行了评分。在一项包含 381 名 3-5 岁儿童父母的横断面研究中，对最终版本的 MIS-EC 进行了评估，以评估其结构效度、内部一致性和重测信度。从项目汇集中共确定了 22 个项目。经过项目删减，选择了 8 个项目组成 MIS-EC，此外还有 2 个一般问题。MIS-EC 表现出良好的内部一致性（儿童影响部分的 Cronbach's alpha = 0.79，家庭影响部分的 Cronbach's alpha = 0.53），重测信度极好（ICC = 0.94），地板效应为 55.7%，天花板效应为 0%。MIS-EC 评分表明 OHRQoL 较差与错畸形的存在显著相关（p < 0.05）。MIS-EC 可靠且有效，可用于评估错畸形对学龄前儿童及其父母/照顾者 OHRQoL 的影响。
