ABSTRACT
OBJECTIVE: The aim of the study was to validate the multimedia version of the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) Axis II Questionnaire in Portuguese language. MATERIAL AND METHODS: The sample comprised 30 patients with signs and symptoms of temporomandibular disorders (TMD), evaluated at the Orofacial Pain Control Center of the Dental School of the University of Pernambuco, Brazil, between April and June 2006. Data collection was performed using the following instruments: Simplifed Anamnestic Index (SAI) and RDC/TMD Axis II written version and multimedia version. The validation process consisted of analyzing the internal consistency of the scales. Concurrent and convergent validity were evaluated by the Spearman's rank correlation. In addition, test and analysis of reproducibility by the Kappa weighted statistical test and Spearman's rank correlation test were performed. RESULTS: The multimedia version of the RDC/TMD Axis II questionnaire in Portuguese was considered consistent (Crombrach alpha = 0.94), reproducible (Spearman 0.670 to 0.913, p<0.01) and valid (p<0.01). CONCLUSION: The questionnaire showed valid and reproducible results, and represents an instrument of practical application in epidemiological studies of TMD in the Brazilian population.

Objetivo: O presente estudo teve como objetivo o desenvolvimento da versão multimídia em português do questionário Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD): Axis II. Metodologia: Para desenvolvimento da versão multimídia foi utilizado o software Flash MX 2004 aplicável ao sistema Windows. O grupo de estudo foi de 17 pacientes portadores de Disfunção Temporomandibular (DTM) que procuraram atendimento no Centro de Controle da Dor Orofacial da Faculdade de Odontologia da Universidade de Pernambuco no período de fevereiro a abril de 2006. Para a coleta de dados foram utilizados os instrumentos: Índice Anamnésico Simplificado para triagem dos pacientes com DTM e o RDC/TMD: Eixo II multimídia, que foi submetido a uma validação de face, passando por uma fase de pré-teste da primeira versão para chegar à versão final. Resultados: Na primeira versão multimídia, dentre as 31 questões divididas em 86 subgrupos de perguntas, 12 perguntas (14%) foram modificadas ou receberam explicações adicionais para uma precisa compreensão pelos pacientes, resultando na versão multimídia final. Conclusão: Concluiu-se que essa versão multimídia em português foi desenvolvida de forma satisfatória, a validação de face seguiu a metodologia proposta na literatura e gerou um instrumento de linguagem prática e útil para estudos clínicos e epidemiológicos relacionados a DTM no Brasil.
Purpose: The aim of the present study was to develop a multimedia version of the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) Axis II Questionnaire in Portuguese language. Methods: To build the multimedia instrument the software Flash MX 2004 for Windows OS was used. The study group comprised 17 patients with signs and symptoms of Temporomandibular Disorders (TMD), who were evaluated at the Orofacial Pain Control Center, School of Dentistry of the University of Pernambuco, between February and April 2006. Data collection was performed using the following instruments: Simplified Anamnestic Index (SAI) and RDC/TMD Axis II multimedia version, which was subjected to a face validation. The first version was evaluated in a pretest phase to elaborate the final version in Portuguese. Results: The first multimedia version had 31 major questions divided into 86 subgroups. For the final version, 12 questions (14%) had to be modified or received additional explanations to ensure full understanding by the patients. Conclusion: The development of the multimedia version in Portuguese was satisfactory. The face validation of this RDC/TMD Axis II multimedia followed the methods proposed in the literature and allowed the development of a potential useful instrument for clinical and epidemiological TMD studies in Brazil.
