Patient-Reported Outcome Measurements in Temporomandibular Disorders and Headaches: Summary of Measurement Properties and Applicability

Abstract

Introduction: Several patient-reported outcome measurements (PROMs) are available in the literature to support the evaluation and diagnosis of temporomandibular disorders and headaches. However, clinicians and researchers usually complain that they had no education on PROMs and low overall knowledge about PROMs. Objective: This study aimed to summarize, describing the measurement properties and clinical applicability of the main condition-specific PROMs available in the literature to the assessment of patients with Temporomandibular Disorders and Headaches. Methods: The current manuscript reviewed 10 PROMs commonly used in the field. Four instruments about functioning and disability: 1. Mandibular Function Impairment Questionnaire (MFIQ), 2. Craniofacial Pain and Disability Inventory (CF-PDI), 3. 8-item and 20-item Jaw Functional Limitation Scale (JFLS), and 4. Manchester Orofacial Pain Disability Scale (MOPDS). Two instruments about headache-related disability: 5. Headache-Related Disability Index (HDI) and 6. Headache Impact Test-6 (HIT-6). Three instruments focused on TMD and headache screening: 7. 3Q/TMD, 8. Short-Form Anamnestic Fonseca Index (SFAI), 9. Headache Screening Questionnaire. In addition, one instrument about maladaptive beliefs regarding pain and injury: 10. Tampa Scale for Kinesiophobia for Temporomandibular Disorders (TSK-TMD). Conclusions: The knowledge about the limitations and applicability of the PROMs commonly used to assess TMDs and Headaches can help clinicians and researchers to obtain reliable and valid outcomes to support the decision-making process. The current review recognizes the importance of using patient-reported outcome measures in research and clinical practice. However, our findings call the attention that further studies on the measurement properties of such instruments are imperative.
