To assess the adaptability and validity of the Arabic version of the Malocclusion Impact Questionnaire (MIQ-AR) in patients seeking orthodontic treatment.
This cross-sectional survey was conducted on a convenience sample of 77 Arabic speaking, healthy, 10-16-year-old children, selected based on their personal perception of "needing braces.". The participants completed the MIQ-AR and the Child Perceptions Questionnaire for children aged 11-14 (CPQ11-14), answered two global questions, and had their Index of Orthodontic Treatment Need, Dental Health Component (IOTN.DHC) scores recorded. Construct validity was examined by measuring the correlation between the MIQ-AR score and the responses to the two global questions. Criterion validity was examined by measuring the correlation between the MIQ-AR and both the IOTN.DHC and CPQ11-14 scores.
Moderate positive correlations were observed between the MIQ-AR scores and the first (ρ = 0.320, < 0.001) and second global questions (ρ = 0.388, < 0.001). A strong positive correlation was found between the total CPQ11-14 and MIQ-AR scores (ρ = 0.597, < 0.001). A positive gradient was observed between the MIQ-AR scores and IOTN.DHC scores.
Our results indicate that the MIQ-AR is a valid tool for measuring oral health-related quality of life in patients with malocclusion, with good psychometric parameters. These preliminary findings require further testing in various settings involving a larger and more diverse sample.
评估阿拉伯语版错颌畸形影响问卷（MIQ - AR）在寻求正畸治疗患者中的适应性和有效性。
本横断面调查选取了77名讲阿拉伯语、健康的10 - 16岁儿童作为便利样本，这些儿童是基于他们个人对“需要戴牙套”的认知而入选的。参与者完成了MIQ - AR和11 - 14岁儿童感知问卷（CPQ11 - 14），回答了两个总体问题，并记录了他们的正畸治疗需求指数、口腔健康成分（IOTN.DHC）得分。通过测量MIQ - AR得分与两个总体问题答案之间的相关性来检验结构效度。通过测量MIQ - AR与IOTN.DHC和CPQ11 - 14得分之间的相关性来检验效标效度。
MIQ - AR得分与第一个总体问题（ρ = 0.320，< 0.001）和第二个总体问题（ρ = 0.388，< 0.001）之间观察到中度正相关。CPQ11 - 14总分与MIQ - AR得分之间发现强正相关（ρ = 0.597，< 0.001）。在MIQ - AR得分与IOTN.DHC得分之间观察到正梯度。
我们的结果表明，MIQ - AR是一种测量错颌畸形患者口腔健康相关生活质量的有效工具，具有良好的心理测量参数。这些初步发现需要在涉及更大且更多样化样本的各种环境中进一步测试。
