Oral and orofacial problems may cause a profound impact on children's oral health-related quality of life (OHRQoL) because of symptoms associated with these conditions that may influence the physical, psychological and social aspects of their daily life. The OHRQoL questionnaires found in the literature are very specific and are not able to measure the impact of oral health on general health domains. Consequently, the objective of this study was to evaluate the psychometric properties of the Portuguese version for Brazilian translation of the Pediatric Quality of Life Inventory™ (PedsQL™) Oral Health Scale in combination with the PedsQL™ 4.0 Generic Core Scales.
The PedsQL™ Oral Health Scale was forward-backward translated and cross-culturally adapted for the Brazilian Portuguese language. In order to assess the feasibility, reliability and validity of the Brazilian version of the instrument, a study was carried out in Belo Horizonte with 208 children and adolescents between 2 and 18 years-of-age and their parents. Clinical evaluation of dental caries, socioeconomic information and the Brazilian versions of the PedsQL™ Oral Health Scale, PedsQL™ 4.0 Generic Core Scales, Child Perceptions Questionnaire (CPQ11-14 and CPQ8-10) and Parental-Caregiver Perception Questionnaire (P-CPQ) were administered. Statistical analysis included feasibility (missing values), confirmatory factor analysis (CFA), internal consistency reliability, and test-retest intraclass correlation coefficients (ICC) of the PedsQL™ Oral Health Scale.
There were no missing data for both child self-report and parent proxy-report on the Brazilian version of the PedsQL™ Oral Health Scale. The CFA showed that the five items of child self-report and parent proxy-report loaded on a single construct. The Cronbach's alpha coefficients for child/adolescent and parent oral health instruments were 0.65 and 0.59, respectively. The test-retest reliability (ICC) for child self-report and parent proxy-report were 0.90 [95% confidence interval (CI) = 0.86-0.93] and 0.86 (95%CI = 0.81-0.90), respectively. The PedsQL™ Oral Health Scale demonstrated acceptable construct validity, convergent validity and discriminant validity.
These results supported the feasibility, reliability and validity of the Brazilian version of the PedsQL™ Oral Health Scale for child self-report for ages 5-18 years-old and parent proxy-report for ages 2-18 years-old children.
口腔和口面问题可能会对儿童的口腔健康相关生活质量（OHRQoL）产生深远影响，因为这些病症会导致各种症状，从而影响他们日常生活的身体、心理和社会方面。文献中的 OHRQoL 问卷非常具体，无法衡量口腔健康对一般健康领域的影响。因此，本研究的目的是评估经巴西葡萄牙语翻译后的儿科生活质量量表（PedsQL）口腔健康量表与 PedsQL 4.0 通用核心量表联合使用的心理测量特性。
PedsQL 口腔健康量表经过正向和反向翻译，并进行了巴西葡萄牙语的跨文化适应性调整。为了评估该工具的巴西版本的可行性、可靠性和有效性，在贝洛奥里藏特开展了一项研究，共有 208 名 2 至 18 岁的儿童和青少年及其父母参与。对龋齿进行临床评估，收集社会经济信息和儿童生活质量量表的巴西葡萄牙语版本、PedsQL 4.0 通用核心量表、儿童感知问卷（CPQ11-14 和 CPQ8-10）以及父母感知问卷（P-CPQ）进行评估。统计分析包括可行性（缺失值）、验证性因素分析（CFA）、内部一致性可靠性和 PedsQL 口腔健康量表的测试-重测组内相关系数（ICC）。
巴西葡萄牙语版 PedsQL 口腔健康量表的儿童自我报告和家长代理报告均无缺失值。CFA 显示，儿童自我报告和家长代理报告的五项目均加载在一个单一的结构上。儿童/青少年和家长口腔健康工具的 Cronbach's alpha 系数分别为 0.65 和 0.59。儿童自我报告和家长代理报告的测试-重测可靠性（ICC）分别为 0.90 [95%置信区间（CI）=0.86-0.93]和 0.86（95%CI=0.81-0.90）。PedsQL 口腔健康量表具有可接受的结构有效性、收敛有效性和判别有效性。
这些结果支持了 5-18 岁儿童自我报告和 2-18 岁儿童家长代理报告的巴西葡萄牙语版 PedsQL 口腔健康量表的可行性、可靠性和有效性。
