A Tinnitus Inventory Focusing on Body Function, Activities, and Participation Using the International Classification of Functioning, Disability and Health.

BACKGROUND AND OBJECTIVES

This study describes the development of an International Classification for Functioning, Disability and Health (ICF)-based inventory for tinnitus (ICF-TINI) that measures the impact of tinnitus on the function, activities, and participation of an individual. Subjects and.

METHODS

This cross-sectional study utilized the ICF-TINI, which included 15 items from the two ICF components of body function and activities. We included 137 respondents with chronic tinnitus. Confirmatory factor analysis validated the two-structure framework (body function, activities and participation). The model fit was assessed by comparing fit values of chi-square (df), root mean square error of approximation, comparative fit index, incremental fit index, and Tucker-Lewis index, with the suggested fit criteria values. Cronbach's alpha was used to assess internal consistency reliability.

RESULTS

The fit indices confirmed the presence of two structures in ICF-TINI, while the factor loading values suggested each item's goodness of fit. The ICF-internal TINI exhibited high consistency reliability (0.93).

CONCLUSIONS

The ICFTINI is a reliable and valid tool for assessing the impact of tinnitus on an individual's body function, activities, and participation.
