Background To promote healthy aging, the social participation needs of older adults must be better met. Previous studies have shown the bene ts of the Personalized citizen assistance for social participation (APIC), but few explored its in uence on attendants. This study explored the assistance experience of attendants when providing the APIC to older adults with disabilities. Methods A qualitative design inspired by a phenomenological approach was used with six female attendants who participated in individual interviews. Results The APIC attendants felt useful, developed meaningful relationships with their older adults, and improved their self-knowledge. Attendants had the opportunity to re ect on their lives and self-aging. They contributed to older adults' functional independence, motivation, and participation in social activities. Attendants encountered challenges related to withdrawn behavior in older adults, such as refusing to participate in activities. Conclusions Considering the identi ed bene ts of the APIC for attendants, further studies should explore personalized assistance to preserve older adults' health. Background Demographic changes lead to challenges requiring concrete interventions to preserve older adults' health and functional independence while avoiding an overburdened healthcare system. In Quebec, some plans have been implemented to improve the living conditions of older adults and avoid or delay chronic illness and disabilities, such as the Quebec Action Plan for all ages [1]. Despite these actions, some older adults' social participation needs are still unmet [2, 3]. De ned as 'a person's involvement in activities that provide interactions with others in the community' [4], social participation is a determinant of older adults' health [5, 6, 7]. Indeed, social participation is a key element of well-being [8], quality of life [9, 10], and a strategy to preserve mobility [11]. Interventions to improve the social participation of older adults, whether they be individual, in a group, formal or informal, are often unavailable [12, 13] or respond inadequately to older adults' needs [14]. When lacking social participation opportunities, older adults, especially those with disabilities, resign themselves to their situation and stay at home [2]. Many older adults are also
