Validation of the mandarin tinnitus evaluation questionnaire: A clinician-administered tool for tinnitus management.

This study sought to validate the applicability of the mandarin Tinnitus Evaluation Questionnaire (TEQ), a brief score method administered by clinicians to quantify the tinnitus severity.A descriptive observational questionnaire study in regard to psychometric properties and practicability was conducted with a total of 414 primary tinnitus outpatients, in which 173 of 414 patients completed the follow-up after receiving an intervention based on the tinnitus educational counseling and the life-style adjustment guidance. For quantifying the tinnitus severity, the TEQ and other 2 self-report questionnaires, Tinnitus Handicap Inventory and visual analog scale, were administered on patients' first-visit and follow-up. With the psychometric analysis, we evaluated the performance of TEQ in tinnitus management, including distinguishing patients with varying severity and detecting the treatment-related outcome.At the first visit, the TEQ showed an excellent inter-rater reliability (Pearson correlation, 0.97, P < .01), a good internal consistency reliability (Cronbach's α, 0.79), and an acceptable convergent validity (Pearson correlation, 0.78 with the Tinnitus Handicap Inventory; 0.62 with a single-question visual analog scale, P < .01). In detecting the treatment-related change, a large effect size of TEQ verified a sensitive responsiveness. After estimating the test-error, a 2-point reduction (2/21) of the TEQ was recommend to be considered a reference outcome indicator for the effective intervention.Even though the TEQ is scored by clinician, it can reflect the clinical features of tinnitus patient. Flexible and simple assessing process makes it a practical tool for patient intake, intervention selection, and outcome measurement.
