While different measures have been validated and used to assess the oral health related quality of life (OHRQoL) of children and adolescents, no previous study has tested the psychometric performance of OHRQoL amongst the most marginalized adolescents, living in extremely deprived neighbourhoods like urban slums and resettlement areas in modern cities. Our study assessed the internal consistency reliability, construct validity and Minimally Important Difference (MID) of the Child-OIDP in a sample of adolescents aged 12-15 years reporting oral health problems that lived in three different types (including two extremely vulnerable) of neighbourhoods (urban slums, resettlement colonies, and middle and upper middle-class neighbourhoods) in the National Capital Territory of Delhi.
We conducted data analysis on a cross-sectional study, comprising of 840 adolescents. The Child-OIDP was used as a measure of OHRQoL. Internal consistency reliability was tested using the standardized Cronbach's Alpha Coefficient. The Child-OIDP was also tested for content and construct validity (the latter through the median test), while a distribution-based approach was used to identify the MID.
The Indian Child-OIDP showed good internal consistency, as the Cronbach's alpha coefficient was 0.77. Inter-item correlation coefficients among the items ranged from 0.13 to 0.50, with the mean inter-item correlation being 0.30. The corrected item-total correlations ranged from 0.30 (social contact) to 0.54 (speaking). For construct validity, the Child-OIDP extent was significantly associated with three subjective oral and general health variables in the expected direction. The calculated effect sizes for these differences indicated that they were moderate (0.50-0.79). We also calculated the standard error of measurement (SEM) of Child-OIDP extent as 0.75.
This study demonstrated that the Indian Child-OIDP is a reliable and valid measure for the assessment of the oral health related quality of life among Indian adolescents especially from marginalised and socioeconomically vulnerable groups. This is an essential step towards assessing oral health and evaluating oral health promotion interventions in those populations and settings.
虽然已经验证和使用了不同的措施来评估儿童和青少年的口腔健康相关生活质量（OHRQoL），但以前没有研究在居住在城市贫民窟和现代化城市安置区等极度贫困社区的最边缘化青少年中测试 OHRQoL 的心理测量性能。我们的研究评估了在德里国家首都辖区的三种不同类型（包括两个极其脆弱的类型）社区（城市贫民窟、安置区和中上层阶级社区）中报告口腔健康问题的 12-15 岁青少年样本中儿童口腔影响生活质量调查问卷（Child-OIDP）的内部一致性信度、结构效度和最小重要差异（MID）。
我们对一项横断面研究进行了数据分析，该研究包括 840 名青少年。儿童口腔影响生活质量调查问卷被用作 OHRQoL 的测量工具。使用标准化的 Cronbach's Alpha 系数测试内部一致性信度。还通过中位数检验测试了儿童口腔影响生活质量调查问卷的内容和结构效度，同时使用基于分布的方法来确定 MID。
印度儿童口腔影响生活质量调查问卷显示出良好的内部一致性，Cronbach's alpha 系数为 0.77。项目间相关系数在 0.13 到 0.50 之间，平均项目间相关系数为 0.30。校正后的项目总分相关性在 0.30（社会接触）到 0.54（说话）之间。对于结构效度，儿童口腔影响生活质量调查问卷的程度与三个预期方向的主观口腔和一般健康变量显著相关。这些差异的计算效应大小表明它们是中度的（0.50-0.79）。我们还计算了儿童口腔影响生活质量调查问卷程度的测量误差标准（SEM）为 0.75。
这项研究表明，印度儿童口腔影响生活质量调查问卷是一种可靠和有效的评估印度青少年口腔健康相关生活质量的工具，特别是来自边缘化和社会经济脆弱群体的青少年。这是在这些人群和环境中评估口腔健康和评估口腔健康促进干预措施的重要一步。
