Smartphone app-based intervention for reducing stress, depression, and anxiety in caregivers of people with dementia in Vietnam: Study protocol for a pilot randomized controlled trial

ObjectivesThis study aims to: (1) identify the information required by family caregivers of people with dementia to be targeted within our dementia family caregiver intervention and (2) test the feasibility of the intervention and methodology to underpin a fully powered randomized controlled trial. MethodsThe study setting will be the Department of Geriatrics at Gia Dinh People's Hospital in Ho Chi Minh City. Inclusion criteria will be the family caregivers of people with dementia living in the community, who attend the Department and use smartphones. In phase 1, we will identify the intervention content with family caregivers of people with dementia through 20 in-depth interviews to determine what information and skills they need. In phase 2, a pilot randomized control trial design will be conducted, with 60 family caregivers of people with dementia being assigned to the intervention or control group by the block randomization method with a ratio of 1:1. The intervention will include weekly, online, psycho-educational, group sessions hosted on the Zalo app. The participants will complete questionnaires at baseline, immediately postintervention, and 3-month postintervention. The feasibility of the intervention and methodology will be assessed, including the rates of recruitment, retention, completion of assessments, and acceptability of the intervention. ResultsThe required information and skills in phase 1 may include dealing with worrying behavior changes in people with dementia, emotional support, and seeking support sources. The rates of recruitment, retention, completion of assessments, and acceptability of the intervention will be obtained in phase 2. The scores of symptoms of stress, depression, and anxiety in the intervention group may be lower than those in the control group at postintervention and 3-month postintervention. ConclusionThe study will provide a foundation for a fully powered clinical trial for the smartphone app-based intervention to reduce stress, depression, and anxiety among family caregivers of people with dementia in Vietnam.
