Summary
Mindfulness-based interventions significantly reduce stress and anxiety in caregivers of individuals with dementia, according to a meta-analysis of 13 randomized trials. The findings reveal that interventions lasting eight weeks or more effectively lower depressive symptoms among caregivers. While these therapies show promise for enhancing mental well-being, they do not significantly alleviate caregiver burden or depression immediately after the intervention. This suggests mindfulness practices can be valuable tools for supporting caregivers, warranting further exploration into their long-term benefits and optimal implementation strategies.
Abstract
Mindfulness-based interventions are becoming increasingly popular and are effective in lowering depressive symptoms and caregiver burden. However, the overall efficacy of therapies in stress and anxiety management is unreported, and no study to date has performed a subgroup analysis to investigate the intervention dose response of outcomes. To quantitatively identify the effectiveness of mindfulness-based interventions for caregivers of persons living with dementia. A comprehensive literature search of six databases was undertaken from the date of inception to June 18, 2023. The DerSimonian-Laird model with random effects was used to examine the overall effect and its heterogeneity in the studies. Version 2 of the risk of bias (RoB 2) tool was employed to analyze the publication bias of each randomized study. Funnel and forest plots were created to represent the findings. Thirteen randomized trials were included in the meta-analysis. Mindfulness-based interventions significantly reduced stress and anxiety of caregivers of persons living with dementia. In addition, interventions provided for ≥8 weeks were beneficial in reducing depression in caregivers. However, mindfulness-based interventions did not offer significant benefits in reducing depression or caregiver burden immediately after the intervention. Mindfulness-based interventions have the potential to help caregivers of people living with dementia. This study could be used as a model for future research into and implementation of mindfulness-based therapies for caregivers. Mindfulness-based therapies appear to alleviate stress and anxiety but are ineffective in reducing depression and burden in caregivers of persons living with dementia. Well-designed RCTs with more rigorous methodology and a larger sample size should be conducted to firm the conclusion of the effectiveness of mindfulness-based interventions for caregivers of persons living with dementia.
