Utilization of home-based care and its buffering effects between dementia caregiving intensity and caregiver burden in China

Abstract Background Home-based care (HBC) services have gained global attention for their potential to reduce caregiver burden among informal caregivers of persons with dementia (PwDs), who experience high caregiving intensity. However, research on HBC and its effects on dementia caregiving in China remains limited. Methods Data were collected from primary caregivers of PwDs in Jiangsu Province, China. Caregiving intensity and HBC utilization were measured using self-developed instruments. Caregiver burden was assessed by The Burden Scale for Family Caregivers-short. Factor analysis was employed to decompose HBC services. Hierarchical multiple regression analysed the moderating effects of HBC on the relationship between caregiving intensity and burden. Results A community sample of 318 caregiver and PwDs dyads was included. Caregivers averagely aged 62.16 years, with 61% being female, 84% not employed, and 66.2% having low income. PwDs aged 77.45 years averagely, with 52.8% being female and an average behavioural problems score of 42.27. Caregivers averaged 15.19 on response measures. The number and time spent on ADL-based tasks were positively associated with caregiver burden (β = 0.26, p
