IntroductionFamily members are the primary source of support for the growing number of people living with dementia (PLWD) worldwide. However, caring for a person living with dementia can have detrimental impacts on the carer quality of life (QoL). This review of systematic reviews explored the factors associated with the QoL of family carers of PLWD and interventions aimed at improving their QoL.Sources Of DataSeveral health-related databases (PUBMED, Psychinfo, Google Scholar and COCHRANE) were consulted in November 2022. Nineteen systematic reviews were included, and their methodological quality was assessed via AMSTAR-2.Areas Of AgreementBetter carer physical and mental health, provision of formal support, relationship quality between carers and PLWD, as well as positive psychological traits were associated with better carer QoL. There is no one-size-fits-all intervention that can improve the QoL of all carers, but promising results were found in most of the interventions.Areas Of ControversyThere is inconsistency in evidence on the association between the carer age and QoL. The use of a wide range of QoL measures, particularly generic QoL scales, has contributed to inconsistencies when comparing the efficacy of interventions.Growing PointsEvidence suggests the need for a person-centred approach to improving carer QoL, considering individual and contextual needs as well as the continuum and progressive nature of dementia care.Timely Areas For Developing ResearchFuture research should be focused on understanding how to best implement and measure person-centred care approaches to carer QoL, including cost-effectiveness. More qualitative studies are necessary to explore carer negative and positive experiences of QoL.© The Author(s) 2023. Published by Oxford University Press. All rights reserved.
