Adherence to Online Interventions for Family Caregivers of People With Dementia: A Meta-Analysis and Systematic Review.

• What is the primary question addressed by this study? What factors influence intervention adherence among family caregivers of people with dementia? • What is the main finding of this study? The study uncovered predictors of intervention adherence among dementia caregivers, providing insights into dropout rates and reasons behind them, thereby informing the design and implementation of more effective online treatments. Specifically, the findings emphasized the necessity of tailoring interventions to address the specific shared needs of caregivers, highlighting the importance of integrating social component features, such as human-based interaction, with comprehensive discussions on their implications. • What is the meaning of the finding? Understanding predictors of intervention adherence can inform the development of more effective and tailored online interventions for dementia caregivers in research and clinical practice, enhancing support and ultimately improving dementia care outcomes. Online interventions hold promise in supporting the well-being of family caregivers and enhancing the quality of care they provide for individuals with long-term or chronic conditions. However, dropout rates from support programs among specific groups of caregivers, such as caregivers of people with dementia, pose a challenge. Focused reviews are needed to provide more accurate insights and estimates in this specific research area. A meta-analysis of dropout rates from available online interventions for family caregivers of people with dementia was conducted to assess treatment acceptability. A systematic search yielded 18 studies involving 1,215 caregivers. The overall pooled dropout rate was 18.4%, with notable heterogeneity indicating varied intervention adherence. Interventions incorporating human contact, interactive features, and personalization strategies for specific types and stages of dementia predicted significantly lower dropout rates. Methodological assessment revealed variability in study quality. Findings support the effectiveness of social support, personalization strategies, and co-design in enhancing intervention adherence among dementia family caregivers. Further research is needed to explore factors influencing dropout rates and conduct robust trials to refine the implementation of future interventions. [ABSTRACT FROM AUTHOR]
