Functional performance in older adults with hearing loss: Application of the International Classification of Functioning brief core set for hearing loss: A pilot study

Abstract

Objectives: The beta version of the International Classification of Functioning, Disability, and Health (ICF) brief core set for hearing loss in adults was developed and recommended to be validated through the audiologic rehabilitation clinical practice. The aims of this pilot study were to validate the ICF brief core set by examining the dimensions of hearing performance measures used in a standard care university clinic specializing in amplification, and seeing if those dimensions support the structure provided by the core set.

Design: ICF linking, classification, and qualifier coding procedures were applied on a data set identified from clinical records and two paper-pencil questionnaires; and completed by consensus of two experienced audiologists.

Study sample: Forty-nine participants were recruited from an out-patient population at an audiology clinic.

Results: Eighteen of 27 items from the brief core set were able to be linked and validated. Four factors were identified, and confirmed the structure of ICF concept: Auditory function, Other functions, Activities/contextual interaction, and Third-party disability. Further, three predictors significantly discriminated performance in 28 participants: the use of hearing assistive devices, speech-reading, and active social life.

Conclusions: The ICF brief core set is a valuable tool for use in audiologic rehabilitation clinical practice and research design.
