Purpose: Objective audiological assessments provide valuable insights on physiological dimensions of hearing loss (HL), but not on lived experiences and functional limitations perceived by individuals. This study employed the multidimensional ICF framework to explore how demographic and diagnostic variables predict self-reported disability in adults with HL.

Method: This cross-sectional study included 571 participants from India (94), South Africa (79), Sweden (219), and the USA (179). Responses from structured interviews based on the ICF were measured against demographic and diagnostic variables.

Results: 74.6% of the participants were hearing aid (HA) users with moderate-to-severe HL. Five statistically significant predictors were identified; HA usage, degree of HL, level of education, age, and income bracket. The predictors were associated with the ICF components; body functions (b126, b210, b230, b240), activity and participation (d310, d350) and environmental factors (e125, e250, e310, e355, e410, e460).

Conclusions: This study emphasises that an individual's experience with HL is significantly influenced by various factors beyond the severity of the HL itself. This underscores the ICF's utility in capturing the complex interplay of biopsychosocial factors on HL. Identifying significant predictors could aid in tailoring interventions to improve health outcomes and quality of life for individuals with HL.
