Aims: The current study aimed to investigate the impact of carer-related modifiable factors (i.e., knowledge about dementia, psychological inflexibility, self-compassion and hours of support from other family members) on quality of life (QoL) among family carers. Methods: A multiple regression analysis was conducted with QoL as a dependent variable. All factors were entered into the model simultaneously as independent variables. Ninety-one family carers with a mean age of 69.5 years old were assessed.
