In addition, its diagnosis is complex and requires the use of valid and reliable instruments for use in epidemiological studies. Objective: To validate the Epidemiological Diagnostic Instrument for TMD (EDI/TMD), with applicability for national epidemiological studies. Methodology: This is a validation study, internal structure validity through Exploratory Factor Analysis (EFA), reliability (internal consistency, interobserver and intraobserver), and convergent validity of the EDI/TMD were assessed using the Diagnostic Criteria for Temporomandibular Disorders (DC/TMD) as the gold standards. The sample was composed of 221 volunteers, 120 in the EFA stage, 50 for the test-retest, and 101 for convergent validity. Results: AFE showed three factors (Muscles TMD, Joint TMD, and Differential Diagnosis) with all items having factor loadings > 0.4, which explained 73.3% of the total variance. Good internal consistency with Cronbach's alpha= 0.775. Reliability ranged from substantial to excellent, reproducibility interobserver (Kappa=0.74-1.00, ICC=0.91-0.97; p< 0.001) and intraobserver (Kappa= 0.75-1.00, ICC=0.80-0.98; p< 0.001). The EDI/TMD total score showed valid and satisfactory diagnostic criteria according to the DC/TMD (Kappa= 0.906; p<0.001), with the ability to differentiate between individuals without and with TMD with a cut-off point of 4.9 (Sensitivity=1.0; Specificity=1.0; AUR=1.0); Mixed TMD with a cut-off point of 14 or more (Sensitivity=0.8; Specificity=1.0; AUR=0.987); and either Muscles TMD (Sensitivity=1.0; Specificity= 0.88; PPV= 0.89; NPV=1.0) or Joint TMD (Sensitivity=0.95; Specificity= 0.87; PPV= 0.83; NPV=0.96), with a cut-off point between 5-13.9, with the diagnosis obtained from the highest score in each factor (Muscles or Joint). Conclusion: The EDI/TMD is a valid and reliable assessment tool, with adequate and satisfactory psychometric properties, capable of diagnosing people with TMD and classifying the subtype of the condition (Muscles, Joint, and Mixed).Acesso AbertoSíndrome da Disfunção da Articulação TemporomandibularInquéritos e questionáriosDiagnósticoEstudos de validaçãoConfiabilidade dos dadosdoctoralThesisCNPQ::CIENCIAS DA SAUDE::ODONTOLOGIA
