Abstract

Objective: To assess the validity and reliability of the Turkish version of the Mandibular Function Impairment Questionnaire (MFIQ-TR).

Methods: Included in this study were 248 patients diagnosed with temporomandibular disorder (TMD) according to Diagnostic Criteria for TMD Axis I protocol. Construct-related validity was evaluated through internal and external construct validity; convergent and divergent validities were evaluated by the average variance extracted (AVE), composite reliability (CR), and bivariate correlations between factors. Reliability was assessed by internal consistency and test-retest reliability.

Results: All items of the MFIQ-TR had content validity and factor loadings above 0.5. The model statistics indicated a good fit. The convergent validity was very good (AVE > 0.5 and CR > 0.7), and the discriminant validity was satisfied. Internal consistency and test-retest reliability of the MFIQ-TR were excellent.

Conclusion: The MFIQ-TR is a valid and reliable instrument for evaluating the impairment of mandibular function in Turkish patients with TMD.

土耳其版下颌功能损伤问卷的有效性和可靠性。

目的：评估土耳其版下颌功能损伤问卷（MFIQ-TR）的有效性和可靠性：评估土耳其版下颌功能损伤问卷（MFIQ-TR）的有效性和可靠性：根据 TMD Axis I 诊断标准，248 名患者被诊断为颞下颌关节紊乱症 (TMD)。通过内部和外部建构效度评估建构相关效度；通过平均方差提取（AVE）、复合信度（CR）和因子间的双变量相关性评估收敛效度和发散效度。信度通过内部一致性和重复测试信度进行评估：MFIQ-TR的所有项目都具有内容效度，因子载荷均在0.5以上。模型统计显示拟合度良好。收敛效度非常好（AVE>0.5，CR>0.7），判别效度令人满意。结论：结论：MFIQ-TR 是评估土耳其 TMD 患者下颌功能受损情况的有效、可靠的工具。

期刊介绍： CRANIO: The Journal of Craniomandibular & Sleep Practice is the oldest and largest journal in the world devoted to temporomandibular disorders, and now also includes articles on all aspects of sleep medicine. The Journal is multidisciplinary in its scope, with editorial board members from all areas of medicine and dentistry, including general dentists, oral surgeons, orthopaedists, radiologists, chiropractors, professors and behavioural scientists, physical therapists, acupuncturists, osteopathic and ear, nose and throat physicians. CRANIO publishes commendable works from outstanding researchers and clinicians in their respective fields. The multidisciplinary format allows individuals practicing with a TMD emphasis to stay abreast of related disciplines, as each issue presents multiple topics from overlapping areas of interest. CRANIO''s current readership (thousands) is comprised primarily of dentists; however, many physicians, physical therapists, chiropractors, osteopathic physicians and other related specialists subscribe and contribute to the Journal.
