Group-Based Interventions for Carers of People With Dementia: A Systematic Review.

Background and objectivesIt is well documented that caring for someone with dementia is associated with many negative mental health outcomes, such as depression, anxiety, and a reduction in quality of life. Group-based interventions are one strategy for improving well-being for carers, but previous systematic reviews have reported inconsistent findings about the efficacy of group-based interventions for carers of people with dementia.Research design and methodsThis systematic review investigates the qualitative and quantitative evidence for the effectiveness of group-based interventions and identifies targets for future research. Narrative synthesis was used to analyze the data.ResultsA comprehensive search of 4 databases revealed 117 potentially relevant studies, 19 of which met the full inclusion criteria. Five studies investigated group cognitive behavioral therapy, 8 investigated psycho-educational interventions, and 6 investigated support groups. The effectiveness of the interventions varied widely, even within subcategories. No type of intervention was consistently shown to improve well-being, though qualitative data and data about participant satisfaction was generally very positive.Discussion and implicationsBased on the quality and quantity of the evidence currently available, there is not enough evidence to reach firm conclusions about the impact of group-based interventions on well-being. In order to establish the effectiveness of group-based interventions there needs to be more high-quality studies with larger sample sizes about this topic. Future research may benefit from the use of mixed methods data collection to explore the disparity between qualitative and quantitative findings in the literature.
