Validation of the multimedia version of the RDC/TMD axis II questionnaire in Portuguese

Abstract

ObjectiveThe 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 methodsThe 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: Simplified 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.ResultsThe 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).ConclusionThe questionnaire showed valid and reproducible results, and represents an instrument of practical application in epidemiological studies of TMD in the Brazilian population

Prevalência de desordens temporomandibulares em indivíduos desdentados reabilitados com próteses totais convencionais

“…O RDC é uma das classificações diagnósticas disponíveis na literatura mais amplamente utilizada e para a qual foram relatados níveis de confiabilidade mais aceitáveis 12 . Por esse motivo, foi o método escolhido para realizar o exame clínico anamnésico dos participantes da pesquisa, através do questionário que se encontra validado em língua portuguesa 13 .…”

“…Para a realização dos exames de DTM, há um manual 13 que deve ser seguido com as especificações necessárias para o diagnóstico. Estas especificações constam de instruções gerais para os exames, como a posição do paciente na cadeira, a posição da mandíbula e dos dentes, algum tipo de barreira física que possa interferir na palpação muscular ou articular (barba, colar), o padrão de abertura para medir desvio de linha média, a extensão vertical do movimento mandibular (abertura sem/com a presença de dor, overbite) e ruídos da ATM.…”

Assessment of cross-cultural adaptations and measurement properties of self-report outcome measures in Portuguese relevant to temporomandibular disorders: a systematic review

“…Two articles and one book chapter ( Figure 1) were included by manual search, totaling nine eligible studies. Four different instruments were translated/adapted into Portuguese, namely: Research Diagnostic Criteria for Temporomandibular Disorders: Axis II (RDC/TMD) [11][12][13][14] , Questionnaire and Anamnesic Index of Fonseca 5,15 , Questionnaire of the American Academy of Orofacial Pain (QAAOP) 2,16 and Mandibular Function Impairment Questionnaire (MFIQ) 17 (Table 1). Among the nine studies analyzed, four translated and/or adapted an instrument.…”

“…In this review, it was possible to identify that most that most of the questionnaires had their concordance assessed, and only two of them 12,13 showed adequate results, however, both of them assessed the RDC/TMD (Table 2). Two different studies have also examined the concordance: one assessed the QAAOP 16 ; the other, the Questionnaire and Anamnesic Index of Fonseca 5 , but had minimally important change within the limits of concordance.…”

“…The internal consistency was assessed on the RDC/ TMD 12,13 and the MFIQ 17 , through the Cronbach's alpha, with results considered positive. Another study which evaluated the internal consistency of the RDC/ TMD 14 has obtained a Cronbach's alpha ranging from 0.68 to 0.73, which was not considered to be appropriate.…”
