Effectiveness of online dementia caregivers training programs: A systematic review

•Online interventions improve the condition and preparedness of caregivers, but future evaluations should consider study designs with multiple time points, control groups, and content that is personalized and interactive.•Results are encouraging that the training programs included in this systematic review improved caregiver knowledge, self-efficacy, anxiety, depression, caregiver burden and satisfaction.•Results, however, were less consistent when evaluating competency, stress, and care recipient status. Over the next thirty years, Alzheimer's disease rates will increase alongside global aging. With the anticipated increase in demand, knowledgeable and skilled dementia caregivers will be in need across the long-term care spectrum. This study is a systematic review of online dementia-based training programs for formal and informal caregivers conducted to analyze evidence for using online training programs. We used the Preferred Reporting Items for Systematic Reviews (PRISMA) method. Methodological quality was assessed by the Cochrane Collaboration Back Review Group criteria. No previously published systematic review has analyzed online dementia training programs among both formal and informal caregivers. A systematic search of Web of Science, PsychInfo, and PubMed resulted in a final sample of (N = 19) studies. Results suggest that online interventions improve the condition and preparedness of caregivers, but future evaluations should consider study designs with multiple time points, control groups, and content that is personalized and interactive.
