[Study on reliability and validity of the Tinnitus Evaluation Questionnaire].

Objective: To investigate the value of the Tinnitus Evaluation Questionnaire (TEQ) in clinical application.
Methods: Cronbach's α coefficient was used to examine the reliability of the TEQ internal consistency. Examined the re-measured reliability by the correlation coefficient by two doctors' 1 - 3 hours interval questionnaires' scores. And inspected criteria validity according to the correlation coefficient of the TEQ and Tinnitus Handicap Inventory (THI).
Results: In the 202 tinnitus patients, the TEQ Cronbach's α coefficient was 0.76 and re-measured reliability was 0.938. The THI correlation coefficient was 0.769. Among which, 99 patients feel tinnitus alleviated obviously after the treatment, the TEQ scores were significantly lower than that before the treatment (t = 21.42, P < 0.001).
Conclusions: The TEQ reflects the severity of tinnitus completely, and has preferable reliability and validity. The characteristics are concise, practical and exact. It is worthy of clinical application.
