This rapid review of systematic reviews examines non-professional interventions that have been implemented to support family caregivers of older adults with dementia who are living in the community. There is a robust body of empirical literature examining such interventions for family caregivers; therefore, this rapid review includes only systematic reviews. MEDLINE, CINAHL, and EMBASE databases were searched from September 2020 to December 2020, and 19 systematic reviews were selected for a full review. Psychosocial, psychoeducational, social support, and multicomponent interventions consistently show positive impacts on a variety of outcomes. The evidence suggests that multicomponent interventions that are tailored to the needs of individual caregivers are the most impactful interventions and should be utilized in future program development. The most effective combination of interventions is unknown and warrants further investigation. However, the repeated success of psychoeducational, psychosocial, and social support interventions suggests that when used together, they may be a successful combination that contributes to positive impacts on caregivers. This multicomponent intervention should be flexible, as interventions are most effective when they are tailored to the individual needs of caregivers and adapted over time as the needs of the caregiver and person living with dementia change with disease progression.
