Long-term care for older people with dementia can adversely impact a family caregiver's life. A decrease in their quality of life may compromise the quality of care they provide to older people and their own quality of life. The samples include 76 family caregivers of older people with dementia in Thailand. Six questionnaires and the EuroQoL Five Dimensions Questionnaire were used in data collection. Descriptive and inferential statistics were used in data analysis. The findings revealed that quality of life of family caregivers was at a high level.
