BACKGROUND The Pediatric Quality of Life Inventory™ (PedsQL™) Oral Health Scale was developed to measure oral health-related quality of life (OHRQoL). The aim of this study was to cross-culturally adapt the parent-reported version for toddlers of PedsQL™ Oral Health Scale into Spanish and to assess the acceptability, reliability and validity of this version in Chilean preschool population. METHODS The PedsQL™ Oral Health Scale for toddlers was cross-culturally adapted for the Spanish language using the recommended standards. To assess metric properties, a cross-sectional study was carried out with 301 children aged 2 to 5 years in Carahue, Chile. Chilean versions of the PedsQL™ Oral Health Scale, PedsQL™ 4.0 Generic Core Scales, and Early Childhood Oral Health Impact Scale (ECOHIS) were completed by the children's parents. Dental caries, malocclusion and dental trauma were examined by trained dentists. The PedsQL™ Oral Health Scale was administrated a second time 14-21 days after. The reliability of the scale was verified by analysis of internal consistency (Cronbach's alpha) and reproducibility (Intraclass correlation coefficient - ICC). The validity of the construct was assessed by confirmatory factor analysis and known groups method. The convergent validity was assessed by calculating the Spearman's correlation with the ECOHIS questionnaire. RESULTS The PedsQL™ Oral Health Scale demonstrated good reliability, with Cronbach's alpha coefficient of 0.79 and ICC of 0.85. A moderate-to-strong correlation was found between the PedsQL™ Oral Health Scale and the ECOHIS questionnaire (- 0.64); the PedsQL™ Oral Health Scale score was lower in children with poor than those with excellent/very good oral health (median 100 vs 85, p < 0.001); it also was lower in children with caries than in those caries-free (median 100 vs 90, p < 0.001). No statistically significant differences were found among groups according to malocclusion and traumatic dental injuries. CONCLUSIONS The PedsQL™ Oral Health Scale for toddlers in Spanish showed to be equivalent to the original version, and its psychometric properties were satisfactory for application in a Chilean pre-school population.

适应和验证智利人口中幼儿的PEDSQL™口腔健康量表。

背景技术开发了儿科生活质量量表（PedsQL™）口腔健康量表，以测量与口腔健康相关的生活质量（OHRQoL）。这项研究的目的是跨文化地将家长报告的PedsQL™口腔健康量表的版本改编成西班牙语，并评估该版本在智利学龄前儿童中的可接受性，可靠性和有效性。方法采用推荐标准，针对跨语言适应幼儿的PedsQL™口腔健康量表进行跨文化调整。为了评估度量标准属性，在智利的Carahue对301名2至5岁的儿童进行了横断面研究。智利版本的PedsQL™口腔健康量表，PedsQL™4.0通用核心量表和儿童早期口腔健康影响量表（ECOHIS）由孩子的父母完成。龋齿 由训练有素的牙医检查错牙合和牙齿创伤。在14-21天后第二次使用PedsQL™口腔健康量表。通过分析内部一致性（Cronbach's alpha）和可重复性（类内相关系数-ICC），验证了量表的可靠性。通过验证性因子分析和已知组方法评估构建体的有效性。通过计算Spearman与ECOHIS问​​卷的相关性来评估收敛效度。结果PedsQL™口腔健康量表显示出良好的可靠性，克朗巴赫的α系数为0.79，ICC为0.85。在PedsQL™口腔健康量表和ECOHIS问​​卷之间发现了中等至强相关性（-0.64）；贫困儿童的PedsQL™口腔健康量表评分低于口腔健康优异/非常好儿童（中位数100比85，p <0.001）；患龋儿童的患病率也低于无患龋儿童（中位数100比90，p <0.001）。根据咬合不正和牙齿外伤，各组之间没有统计学上的显着差异。结论PedsQL™西班牙语幼儿口腔健康量表与原始版本相当，其心理计量学特性令人满意，适用于智利学龄前儿童。根据咬合不正和牙齿外伤，各组之间没有统计学上的显着差异。结论PedsQL™西班牙语幼儿口腔健康量表与原始版本相当，其心理计量学特性令人满意，适用于智利学龄前儿童。根据咬合不正和牙齿外伤，各组之间没有统计学上的显着差异。结论PedsQL™西班牙语幼儿口腔健康量表与原始版本相当，其心理计量学特性令人满意，适用于智利学龄前儿童。
