title: Vulvar vestibulitis syndrome: reliability of diagnosis and evaluation of current diagnostic criteria.
abstract: OBJECTIVE
  To assess the reliability of the diagnosis of vulvar vestibulitis as defined by Friedrich and to evaluate the usefulness of Friedrich's criteria in the diagnostic process.
  
  
  METHODS
  In a university hospital, 146 women with dyspareunia had two sets of gynecologic examinations involving vulvar pain ratings, took part in structured interviews, and completed the McGill-Melzack Pain Questionnaire.
  
  
  RESULTS
  Kappa values for the vulvar vestibulitis diagnosis ranged from 0.66 to 0.68 for inter-rater agreement and from 0.49 to 0.54 for test-retest reliability. Mean vestibular pain ratings ranged from 2.45 at the 12 o'clock site to 7.58 at the 9-12 o'clock site; ratings for all sites correlated significantly between gynecologists. Pain in the labia majora and labia minora was minimal for both sets of examinations, with mean participant pain ratings ranging from 0 to 1.49. Gynecologists' erythema ratings did not correlate significantly with respect to either inter-rater agreement or test-retest reliability. Of Friedrich's three diagnostic criteria, only tenderness to pressure within the vulvar vestibule differentiated dyspareunia patients with and without vulvar vestibulitis. In reference to their coital pain, 88.1% of women with vulvar vestibulitis chose adjectives from the McGill-Melzack Pain Questionnaire describing a thermal quality, and 86.6% chose adjectives describing an incisive pressure sensation.
  
  
  CONCLUSIONS
  Vulvar vestibulitis can be reliably diagnosed in women with dyspareunia. Pain is limited to the vulvar vestibule and can be rated and described in a consistent fashion by these women. Erythema does not appear to be a useful diagnostic criterion.
