The abuse of older adults is a societal, and legal issue. A person living with dementia is at high risk for abuse due to their physical and cognitive decline. Objectives This review examined the evidence for interventions to prevent the abuse of people living with dementia in the community. Methods The articles were retrieved from 2000 to 2023 from six databases, including MEDLINE via PubMed, CINAHL Plus via EBSCO, EMBASE, ProQuest Medical Library, Web of Science, and Scopus. The research articles that focused on finding the effectiveness of interventions for preventing abuse of people living with dementia in community settings were included in this review. The review included randomized controlled trials and pre-test post-test trials only. The quality appraisal of the eligible studies was done using ROB 2 and ROBINS II. The findings were tabulated and narratively synthesised. Results Out of 1831 articles, only three were included in this review. Only two RCTs were included in this efficacy review. Both the studies showed that the interventions were not effective in reducing abuse. The studies utilised family caregiver interventions like psychological interventions and online supportive education. The review identified psychological interventions with some evidence. Another study was a quasi-experimental study that used dialectical behaviour therapy as an intervention to reduce abuse occurrence. The study showed low evidence and focused only on reporting of elder abuse as an outcome. Conclusion This review found very few studies and was not able to draw a conclusion on the effectiveness of interventions for abuse in people living with dementia. Given the paucity of research, there is a clear need to identify how to overcome the challenges faced in elder abuse research and further refine the development of approaches to reduce elder abuse among people living with dementia in community settings.
