title: The THI questionnaire: psychometric data for reliability and validity of the Italian version.
abstract: The main objective of this study was to determine reliability, validity, and reproducibility of the Italian version of the Tinnitus Handicap Inventory (THI) self-administered questionnaire aimed at evaluating the impact of tinnitus on the quality of life of subjects affected by this symptom. The questionnaire was presented to a sample of 443 subjects (285 men and 158 women; ages 19-86; mean age, 53) who were referred to our Tinnitus Centre in Rome and came from the entire national territory. All subjects reported as their main problem a tinnitus that had persisted for at least 6 months. Statistical analysis carried out on THI questionnaire results showed high internal consistency and reliability for the total scale (Cronbach's alpha = .94). Despite the poor number of items, the THI proved useful for the functional scale (0.86), the emotional scale (0.89), and the catastrophic scale (0.75).
