Abstract

Background

The Diagnostic Criteria for Temporomandibular Disorders (DC/TMD) is a biaxial tool for TMD assessment. To implement a translated version in the Brazilian context, standardised adaptation and validation are necessary.

Objective (s)

To translate, adapt and verify the measurement properties of the DC/TMD Axis II instruments Pain Drawing (PD), Graded Chronic Pain Scale (GCPS), Jaw Functional Limitation Scale (JFLS) and Oral Behaviours Checklist (OBC).

Methods

The translation and cross-cultural adaptation processes of orofacial-related Axis II instruments followed the Guidelines for Establishing Cultural Equivalency. The validation research was carried out with 117 Brazilians with TMD, in two assessment days. Structural validity, internal consistency, test–retest reliability, measurement error, construct validity—hypothesis testing, and ceiling and floor effects were tested.

Results

PD showed substantial reliability (Kappa 0.63), and GCPS, JFLS and OBC showed excellent reliability over time (intraclass correlation coefficient > 0.85). The internal consistency was adequate for all instruments (Cronbach's alpha > 0.77) except for the functional activities domain of OBC (Cronbach's alpha = 0.48). Construct validity was good for all instruments (75% hypotheses confirmed), except for the OBC total score. Regarding parameters of structural validity, GCPS showed Goodness of Fit Index = 0.98 for the solution with two domains. JFLS and OBC presented Goodness of Fit Index < 0.90 for the solutions with three and two domains, respectively.

Conclusion

The Brazilian Portuguese version of DC/TMD Axis II can be used in Brazil, but more studies are necessary to find an adequate structure for JFLS and OBC in a Brazilian sample.

巴西葡萄牙语版颞下颌疾病诊断标准轴II：翻译，跨文化适应和测量特性。

背景：颞下颌疾病诊断标准（DC/TMD）是一种评估TMD的双轴工具。为了在巴西环境中实施翻译版本，标准化的改编和验证是必要的。目的：翻译、调整和验证DC/TMD轴II仪器疼痛图（PD）、分级慢性疼痛量表（GCPS）、颌骨功能限制量表（JFLS）和口腔行为检查表（OBC）的测量特性。方法：根据《建立文化等值指南》，对面部相关的II轴工具进行翻译和跨文化适应。在两个评估天内，对117名患有TMD的巴西人进行了验证研究。检验了结构效度、内部一致性、重测信度、测量误差、结构效度-假设检验、天花板效应和地板效应。结果：PD具有较高的信度（Kappa 0.63）， GCPS、JFLS和OBC具有较好的信度（类内相关系数> 0.85）。除了OBC的功能活动域（Cronbach’s alpha = 0.48）外，所有仪器的内部一致性都是足够的（Cronbach’s alpha = 0.77）。除了OBC总分外，所有工具的结构效度都很好（75%的假设得到证实）。在结构效度参数方面，GCPS对两域解的拟合优度指数为0.98。结论：巴西葡萄牙语版本的DC/TMD Axis II可以在巴西使用，但需要更多的研究才能在巴西样本中找到合适的JFLS和OBC结构。

期刊介绍： Journal of Oral Rehabilitation aims to be the most prestigious journal of dental research within all aspects of oral rehabilitation and applied oral physiology. It covers all diagnostic and clinical management aspects necessary to re-establish a subjective and objective harmonious oral function. Oral rehabilitation may become necessary as a result of developmental or acquired disturbances in the orofacial region, orofacial traumas, or a variety of dental and oral diseases (primarily dental caries and periodontal diseases) and orofacial pain conditions. As such, oral rehabilitation in the twenty-first century is a matter of skilful diagnosis and minimal, appropriate intervention, the nature of which is intimately linked to a profound knowledge of oral physiology, oral biology, and dental and oral pathology. The scientific content of the journal therefore strives to reflect the best of evidence-based clinical dentistry. Modern clinical management should be based on solid scientific evidence gathered about diagnostic procedures and the properties and efficacy of the chosen intervention (e.g. material science, biological, toxicological, pharmacological or psychological aspects). The content of the journal also reflects documentation of the possible side-effects of rehabilitation, and includes prognostic perspectives of the treatment modalities chosen.
