title: OHIP-TMDs: a patient-reported outcome measure for temporomandibular disorders.
abstract: OBJECTIVE
  This research aims to assess the test-retest reliability, the face, content and known groups validity, and responsiveness to change, of OHIP-TMDs, a 22-item TMDs-specific version of the Oral Health Impact Profile (OHIP).
  
  
  METHODS
  Test-retest reliability - A group of patients with TMDs (n = 20) was administered OHIP-TMDs twice before initial consultation with a 2-week interval. Face and content validity - Content validity index assessments were undertaken with professionals and patients. Known groups validity - Participants (n = 76) with confirmed Axis 1 RDC/TMD diagnoses completed OHIP-TMDs prior to TMDs treatment. Their responses were compared, using inferential statistics, with those of age- and gender-matched controls. Responsiveness to change - Using the same 76 participants, a comparison was made of OHIP-TMDs with OHIP-49 (order of administration randomized) both at baseline and 3 months after starting treatment.
  
  
  RESULTS
  OHIP-TMDs showed good test-retest reliability ICC [2,1] 0.805 (95% CI: 0.565, 0.918); good face and content validity; significant differences (P < 0.001) between controls and participants demonstrating known groups validity. Its responsiveness to change was similar to OHIP-49.
  
  
  CONCLUSIONS
  OHIP-TMDs is an appropriate biopsychosocial, patient-centred, outcome measure for assessing QOL in patients with TMDs. It is less than half the length of OHIP-49 and contains proportionately more items relevant to TMDs.
