The ICF Core Sets for hearing loss: researcher perspective, Part II: Linking outcome measures to the International Classification of Functioning, Disability and Health (ICF).

OBJECTIVE

To link outcome measures used in audiological research to the ICF classification and thereby describe audiological research from the ICF perspective.

DESIGN

Through a peer-reviewed or a joint linking procedure, link outcome measures to the ICF classification system using standardized ICF linking rules. Additional linking rules were developed in combination with the established rules to overcome difficulties when connecting audiological data to ICF. Absolute and relative frequencies of ICF categories were reported.

STUDY SAMPLE

The identified outcome measures from the previous study (Part I) constituted the empirical material.

RESULTS

In total, 285 ICF categories were identified. The most prevalent categories were related to listening, hearing functions, auditory perceptions, emotions and the physical environment, such as noise and hearing aids. Categories related to communication showed lower relative frequencies, as did categories related to the social and attitudinal environment.

CONCLUSIONS

Based on the linked outcome measures, communication as a research topic is subordinated to other research topics. The same conclusion can be drawn for research targeting the social and attitudinal environment of adults with HL. Difficulties in the linking procedure were highlighted and discussed, and suggestions for future revisions of the ICF from the audiological perspective were described.
