Abstract

Background: The temporomandibular joint (TMJ) scale assesses the severity of temporomandibular joint disorders (TMD), yet a European Portuguese translation is lacking.

Objectives: To translate, cross-culturally adapt and to examine the psychometric properties (construct validity and reliability) of the TMJ scale.

Methods: Translation and cultural adaptation were carried out according to international recommendations, including initial translation, evaluation of this translation and cultural adaptation by a panel of experts, and back translation. The final Portuguese version was used to examine the reliability and validity, and participants with TMD were recruited from a Portuguese outpatient clinic. Reliability measures included internal consistency with Cronbach's alpha and test-retest reliability with the intraclass correlation coefficient (ICC2,1). The Spearman correlation comparing the TMJ scale with the Fonseca and Helkimo indexes was used to assess the construct validity.

Results: A total of 63 participants (23 ± 2 years; 61,9% female) were included. Similar internal consistency was observed between the two moments of application (0.921 and 0.918), and test-retest reliability was excellent, with an ICC2,1 = 0.998 (95%CI: 0.988-0.999). Robust positive correlations (rho 0.554-0.611, p < 0.001) were found between the TMJ scale and Fonseca and Helkimo indexes.

Conclusion: The European Portuguese version of TMJ scale is now available to improve the assessment of severity of TMD in routine clinical practice. This version is also reliable and valid.

颞下颌关节量表的葡萄牙语翻译、文化适应性和心理测量特性：一项横断面研究。

背景：颞下颌关节量表（TMJ）可评估颞下颌关节紊乱症（TMD）的严重程度，但目前尚无欧洲葡萄牙语译本：翻译颞下颌关节量表，对其进行跨文化调整，并检验其心理测量特性（结构效度和信度）：方法：根据国际建议进行翻译和文化调整，包括初始翻译、专家小组对翻译和文化调整的评估以及回译。最终的葡萄牙语版本用于检验信度和效度，TMD 患者是从葡萄牙一家门诊诊所招募的。信度测量包括内部一致性（Cronbach's alpha）和测试-再测信度（类内相关系数（ICC2,1））。颞下颌关节量表与 Fonseca 和 Helkimo 指数之间的斯皮尔曼相关性用于评估构建有效性：共纳入 63 名参与者（23 ± 2 岁；61.9% 为女性）。在两个应用时刻之间观察到了相似的内部一致性（0.921 和 0.918），测试-再测可靠性极佳，ICC2,1 = 0.998（95%CI：0.988-0.999）。测试重测可靠性极佳，ICC2,1 = 0.998（95%CI：0.988-0.999）：颞下颌关节量表的欧洲葡萄牙语版本现已可用，可改善常规临床实践中对 TMD 严重程度的评估。该版本同样可靠有效。

期刊介绍： Oral & Maxillofacial Surgery founded as Mund-, Kiefer- und Gesichtschirurgie is a peer-reviewed online journal. It is designed for clinicians as well as researchers.The quarterly journal offers comprehensive coverage of new techniques, important developments and innovative ideas in oral and maxillofacial surgery and interdisciplinary aspects of cranial, facial and oral diseases and their management. The journal publishes papers of the highest scientific merit and widest possible scope on work in oral and maxillofacial surgery as well as supporting specialties. Practice-oriented articles help improve the methods used in oral and maxillofacial surgery.Every aspect of oral and maxillofacial surgery is fully covered through a range of invited review articles, clinical and research articles, technical notes, abstracts, and case reports. Specific topics are: aesthetic facial surgery, clinical pathology, computer-assisted surgery, congenital and craniofacial deformities, dentoalveolar surgery, head and neck oncology, implant dentistry, oral medicine, orthognathic surgery, reconstructive surgery, skull base surgery, TMJ and trauma.Time-limited reviewing and electronic processing allow to publish articles as fast as possible. Accepted articles are rapidly accessible online.Clinical studies submitted for publication have to include a declaration that they have been approved by an ethical committee according to the World Medical Association Declaration of Helsinki 1964 (last amendment during the 52nd World Medical Association General Assembly, Edinburgh, Scotland, October 2000). Experimental animal studies have to be carried out according to the principles of laboratory animal care (NIH publication No 86-23, revised 1985).
