- The multiphase optimisation strategy, combined with fractional factorial design, was used to assess the effects of each intervention component on distressed primary family caregivers of individuals with dementia in Hong Kong.
- Over 12 months, intervention components of mindfulness-based intervention, support group, behavioural activation, and behavioural problems management led to improvements in dementia management strategies, mindfulness attention awareness, psychological well-being, and functional social support, while reducing anxiety and depression symptoms.
