Most of the instruments available to measure the oral health-related quality of life (OHRQoL) in paediatric populations focus on older children, whereas parental reports are used for very young children. The scale of oral health outcomes for 5-year-old children (SOHO-5) assesses the OHRQoL of very young children through self-reports and parental proxy reports. We aimed to cross-culturally adapt the SOHO-5 to the Brazilian Portuguese language and to assess its reliability and validity.
We tested the quality of the cross-cultural adaptation in 2 pilot studies with 40 children aged 5-6 years and their parents. The measurement was tested for reliability and validity on 193 children that attended the paediatric dental screening program at the University of São Paulo. The children were also clinically examined for dental caries. The internal consistency was demonstrated by a Cronbach's alpha coefficient of 0.90 for the children's self-reports and 0.77 for the parental proxy reports. The test-retest reliability results, which were based on repeated administrations on 159 children, were excellent; the intraclass correlation coefficient was 0.98 for parental and 0.92 for child reports. In general, the construct validity was satisfactory and demonstrated consistent and strong associations between the SOHO-5 and different subjective global ratings of oral health, perceived dental treatment need and overall well-being in both the parental and children's versions (p<0.001). The SOHO-5 was also able to clearly discriminate between children with and without a history of dental caries (mean scores: 5.8 and 1.1, respectively; p<0.001).
The present study demonstrated that the SOHO-5 exhibits satisfactory psychometric properties and is applicable to 5- to 6-year-old children in Brazil.
大多数用于测量儿童口腔健康相关生活质量（OHRQoL）的工具都侧重于年龄较大的儿童，而对于非常年幼的儿童则使用父母报告。5 岁儿童口腔健康结局量表（SOHO-5）通过自我报告和父母代理报告来评估非常年幼儿童的 OHRQoL。我们旨在将 SOHO-5 跨文化适应为巴西葡萄牙语，并评估其可靠性和有效性。
我们在两项包含 40 名 5-6 岁儿童及其父母的试点研究中测试了跨文化适应的质量。在参加圣保罗大学儿科牙科筛查计划的 193 名儿童中，对该测量进行了可靠性和有效性测试。还对儿童进行了临床龋齿检查。儿童自我报告的 Cronbach's alpha 系数为 0.90，父母代理报告的 Cronbach's alpha 系数为 0.77，证明了内部一致性。基于 159 名儿童的重复管理，测试-重测信度结果非常好；父母报告的组内相关系数为 0.98，儿童报告的组内相关系数为 0.92。总体而言，结构有效性令人满意，SOHO-5 与不同的主观口腔健康总体评价、感知的牙齿治疗需求和整体幸福感之间存在一致且强烈的关联，无论是在父母版本还是儿童版本中（p<0.001）。SOHO-5 还能够清楚地区分有和无龋齿病史的儿童（平均得分：分别为 5.8 和 1.1；p<0.001）。
本研究表明，SOHO-5 具有令人满意的心理测量特性，适用于巴西 5-6 岁儿童。
