title: Development and validation of the tinnitus primary function questionnaire.
abstract: OBJECTIVE
  To create a questionnaire focused on the primary activities impaired by tinnitus and therefore more sensitive to treatments.
  
  
  METHODS
  Questions were developed on (a) emotions, (b) hearing, (c) sleep, and (d) concentration. A 20-item questionnaire was administered to 158 patients. First, confirmatory factor analysis was used to select 3 questions per domain. Second, factor analysis was used to evaluate the appropriateness of the 12-item questionnaire.
  
  
  RESULTS
  The analysis indicated that the selected questions successfully represented 4 independent domains. Scores were correlated with the Tinnitus Handicap Questionnaire ( r = .77, p < .01) and loudness ( r = .40, p < .01). The Sleep subscale correlated with the Pittsburgh Sleep Index ( r = .68, p < .01); the Emotion subscale correlated with the Beck Inventory ( r = .66, p < .01) and the Trait Anxiety questionnaire ( r = .67, p < .01). The average scores went from 51% to 38% following treatment.
  
  
  CONCLUSIONS
  The Tinnitus Primary Function Questionnaire is valid, reliable, and sensitive and can be used to determine the efficacy of clinical trials.
