To assess the construct validity and reliability of the Brazilian version of the Orthognathic Quality of Life Questionnaire (B-OQLQ).
A cross-sectional study was performed, and 101 patients in need of orthodontic-surgical treatment were recruited at a public hospital (Hospital Universitário Pedro Ernesto) and a public dental school (Faculdade de Odontologia da Universidade do Estado do Rio de Janeiro). The B-OQLQ was self-completed. The mean age of the participants was 26.51 ± 9.25 years, and most were female (58.42%; n = 59). The construct validity was assessed using Spearman's correlation coefficient between the B-OQLQ and the Oral Health Impact Profile (OHIP-14) scores and between the B-OQLQ and subjective health indicators' scores. The reliability was assessed in terms of internal consistency and stability (test-retest) using Cronbach's alpha and the intraclass correlation coefficient (ICC), respectively.
Significant correlations were found between the B-OQLQ scores and the following: OHIP-14 total score (rs = 0.70, P < .001), perception of oral health (rs = -0.24, P = .02), single-item evaluation of quality of life (rs = -0.29, P = .03), satisfaction with physical appearance (rs = -0.40, P < .001), and satisfaction with facial appearance (rs = -0.39, P = .0001). Cronbach's alpha and the ICC was 0.95 and 0.90, respectively. The domains of B-OQLQ causing the most effect on the quality of life included "social aspects of deformity" (13.0 ± 10.54) and "facial aesthetics" (11.81 ± 6.23).
The Brazilian version of the OQLQ was shown to be valid and reliable with good psychometric properties and might thus be considered an appropriate tool to assess the effect of dentofacial deformities on the quality of life of individuals with this condition.
评估巴西版正颌生活质量问卷（B - OQLQ）的结构效度和信度。
进行了一项横断面研究，在一家公立医院（佩德罗·埃内斯托大学医院）和一所公立牙科学院（里约热内卢州立大学牙科学院）招募了101名需要正畸 - 外科治疗的患者。B - OQLQ由患者自行填写。参与者的平均年龄为26.51±9.25岁，大多数为女性（58.42%；n = 59）。使用B - OQLQ与口腔健康影响量表（OHIP - 14）得分之间以及B - OQLQ与主观健康指标得分之间的斯皮尔曼相关系数评估结构效度。分别使用克朗巴哈系数和组内相关系数（ICC）从内部一致性和稳定性（重测）方面评估信度。
发现B - OQLQ得分与以下各项之间存在显著相关性：OHIP - 14总分（rs = 0.70，P <.001）、口腔健康感知（rs = - 0.24，P =.02）、生活质量单项评估（rs = - 0.29，P =.03）、对身体外观的满意度（rs = - 0.40，P <.001）以及对面部外观的满意度（rs = - 0.39，P =.0001）。克朗巴哈系数和ICC分别为0.95和0.90。对生活质量影响最大的B - OQLQ领域包括“畸形的社会方面”（13.0±1
