RESUMEN
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.
