This study aims to investigate whether selected social and psychological characteristics of family caregivers of persons with dementia are related to community-based service use in Belgium. Two aspects were distinguished in service utilisation: volume (number of contacts) and diversity (number of services). Within a selected region, dementia caregivers were traced via the detection of persons with dementia known to community health or social services. A probability diagnosis was made with the Geriatric Mental State and the computer algorithm AGECAT. Family caregivers of persons with dementia (N = 168) were interviewed at home by means of a structured questionnaire. Data were analysed with multiple regression analysis. Co-residence, a positive attitude towards home service use, and increased problem-solving coping were found to be direct predictors of increased diversity of services used, whereas a lower burden of behaviour problems, living apart, and increased avoidance coping were found to be direct predictors of increased volume of service use. Care recipients’ behaviour problems and functional status were not found to be related to service use. The results suggest that social and psychological factors have a larger impact on service use in family caregivers of persons with dementia, compared to objective or subjective burden. Interventions to increase awareness of relevant services, to improve attitudes towards their use and support problem-solving coping in family caregivers may be considered to increase the use of appropriate services.
