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.
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.
