Dementia and depression are highly prevalent and comorbid conditions in older adults and are associated with individual distress, substantial burden for care providers, and high societal costs.
Music interventions represent a highly promising type of non-pharmacological interventions for both dementia and depression in older adults. They are widely used, but have yet to be rigorously tested in large trials.
The MIDDEL trial is the largest trial of music interventions to date, and the first to compare two different approaches – group music therapy (GMT), and recreational choir singing (RCS) – alone and in combination across countries.
MIDDEL is designed as a large, pragmatic, international cluster-randomised controlled trial with a 2x2 factorial design that compares the effects of GMT, RCS, both, or neither, for care home residents aged 65 years or older with dementia and depressive symptoms.
Study sites are located in Australia and in five European countries, and a total of 100 care home units are to be randomised to one of the four study conditions.
