Comparing perspectives from experts and individuals with lived experience in the Global North versus the Global South: ICF core sets for deafblindness

Findings highlight the regional variations in activities and participation among individuals with deafblindness as they reflect differences in environmental factors. Rooted in cultural and resource differences, geographic region itself constitutes a key environmental factor. Expert perspectives may underrepresent differences in lived environmental realities of individuals with deafblindness. Future Core Set development will benefit from including more diverse sources.
