Volunteers Adding Life in Dementia: VALID (VALID)

A Cluster-Randomized Controlled Trial Evaluating the Effects of a Volunteer-Led Nonpharmacological Intervention to Reduce Neuropsychiatric Symptoms of Dementia in Long-Term Care Residents

Older adults with Alzheimer's disease and other forms of dementia frequently develop challenging neuropsychiatric symptoms (NPS) as a result of their illness. Non-pharmacological strategies to manage these symptoms such as music, exercise, and participating in pleasant social events have been demonstrated to be safe and effective strategies to reduce these behavioral symptoms. Our project, Volunteers Adding Life in Dementia (VALID), will design and implement a volunteer-led program to reduce behavioral symptoms and improve the quality of life of older adults with dementia who are residing in long-term care facilities.

The number of older adults with Alzheimer's disease (AD) and related forms of dementia is increasing in Canada and the majority of individuals with dementia develop neuropsychiatric symptoms (NPS) such as agitation, psychosis, depression and anxiety at some time during their illness. NPS are particularly problematic in long-term care (LTC) where approximately 60% of individuals have dementia, and 80% of individuals with dementia have NPS at any time. Adverse outcomes associated with NPS include increased use of psychotropic medications, stress for families and nursing staff, increased costs of care, and decreased quality of life. A novel approach to implementing non-pharmacological interventions for LTC residents with NPS is the use of volunteers. Volunteer-led programs have been demonstrated to be an effective, inexpensive, and sustainable method of implementing psychosocial interventions for older adults in acute care. The objectives of our project are to: 1.) Recruit and train approximately 40 volunteers in the VALID program; 2.) Conduct a cluster-randomized controlled trial of the VALID program in 6 LTC facilities (3 intervention and 3 control LTC sites; 60 individuals with dementia in each of the experimental and control arms) to determine the effect of the VALID program on symptoms of NPS, patient quality of life, volunteer's experience, and LTC staff stress, 3.) Determine key components of the VALID program that served as facilitators and barriers to implementation.

Volunteers will visit 3 times per week with a visit duration of 30 minutes for each visit during the study.
