| Clinical Findings in Temporomandibular Disorders: Challenges to Determining Validity | ||||||||||||||||||||||||
Sponsored by: Behavioral Sciences, Neuroscience / TMJ, International RCD/TMD Consortium, NIDCR | ||||||||||||||||||||||||
| Description: Classification systems for temporomandibular disorders such as the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) characterize somatic and psychosocial TMD aspects. Physical signs are grouped into TMD subcategories (diagnoses) which is desirable for several reasons (e.g., implication for treatment, understanding pathogenesis, formulating etiology and prognosis), but there are significant challenges to determining their validity. The symposium will review the concepts of validity and how they are related to the field of physical TMD signs. Dr. Eric Schiffman (University of Minnesota) will present that the RDC/TMD Axis I exam and questionnaire items have undergone examiner reliability testing. The RDC/TMD Axis I protocol has face and content validity for clustering specific signs and symptoms to reliably identify empirically derived TMD subgroups. Methodology will be described from an ongoing multicenter study to improve RDC/TMD's content validity, and to assess criterion and construct validity. The implications of clinical validity versus the research utility of the TMD subgroups will be discussed. Dr. Charles Widmer (University of Florida) will review several tests proposed to diagnose TMD, and will focus on the respective roles of diagnostic test parameters including receiver operating characteristic (ROC) curves and positive/negative predictive values. He will also review the current status of the diagnostic efficiency of clinical measures for TMD and other orofacial pain conditions. Dr. Gary Slade (University of Adelaide) will provide strategies for evaluating validity as used in other disciplines where no “gold standard” is available (e.g., oral health related quality of life, OHRQoL). This presentation reviews methods and results from studies evaluating validity of OHRQoL and demonstrates the application of those methods to assessments of validity in a prospective cohort study of TMD. Dr. Samuel Dworkin (University of Washington) will be the Discussant, facilitating audience dialogue into this very complex concept, validity | ||||||||||||||||||||||||
