Official title
A Brazilian Version of the STrAtegies for RelaTives (START) Intervention in the Unified Health System (SUS): a Controlled Feasibility Trial
Overview
This controlled trial aims to assess the feasibility of a culturally adapted Brazilian version of the START (STrAtegies for RelaTives) program, a structured coping strategy program designed for family caregivers of people living with dementia. The program will be delivered by trained community general health workers (CGHW) in 10 municipalities across Brazil. Outcomes will include measures of feasibility and acceptability, as well as caregiver burden, mental health, and quality of life, assessed at baseline and after 6 months.
Detailed description
This study will evaluate the feasibility of the START program in the Brazilian Unified Health System (SUS). The intervention was translated and culturally adapted through a structured process that included expert review and focus groups with mental health professionals and community general health workers (CGHW) to ensure the clarity and cultural relevance of the materials.
The intervention will be delivered by trained CGHW to family caregivers of people living with dementia. CGHW will undergo a 16-hour, in-person training provided by the research team. During the period of the intervention, they will receive ongoing remote supervision to support protocol adherence and address challenges encountered in the field.
Ten municipalities-two from each of the five geographical regions of Brazil-will participate. In each municipality, two primary care units (PCU) will be randomly allocated to either the intervention or the waitlist control group.
The selection of participating municipalities will be conducted in collaboration with each state's Bipartite Inter-managerial Commission (Comissão Intergestora Bipartite, CIB). Municipalities will be eligible if they have ≥100,000 inhabitants and agree to participate. Each will be required to list all PCU with ≥15 dementia diagnoses (ICD-10). If a municipality does not have at least two PCU meeting this threshold, units with ≥10 diagnoses may be considered. From this list, two PCU will be randomly drawn. Eligible pairs must meet two conditions: (1) they must be non-contiguous, and (2) their populations must be demographically similar, as assessed by local authorities. If these two criteria are not met, a new draw will be conducted.
Feasibility and acceptability will be assessed as primary outcomes through operational indicators (e.g., number of sessions completed, adherence, dropouts), structured online questionnaires completed by caregivers and CGHW, and semi-structured qualitative interviews conducted with caregivers, CGHW, and municipal health managers.
Secondary outcomes will include caregiver burden, mental health symptoms, quality of life, coping strategies, and neuropsychiatric symptoms of the care recipient. These outcomes will be measured at baseline and again six months after the intervention using validated instruments including the HADS, ZBI, WHOQOL-Bref, Brief COPE, and NPI.
Intervention fidelity will be assessed through randomly selected audio recordings of sessions and structured checklists completed by independent researchers.
Interventions
- Behavioral STrAtegies for RelaTives (START) - Brazilian version
Eight individualized, weekly, home-based sessions will be delivered by trained community general health workers (CGHW). The intervention includes coping strategies, behavior management, and communication skills. Caregivers receive printed materials and structured exercises. CGHW receive a facilitator manual.
Primary outcome measures
- Feasibility questionnaire [Time frame: Approximately 8 weeks post-baseline (after completing the intervention)]
- Operational feasibility metrics [Time frame: Approximately 8 weeks post-baseline (after completing the intervention)]
- Qualitative feasibility interviews [Time frame: Approximately 8 weeks post-baseline (after completing the intervention)]
Secondary outcome measures (6)
- Caregiver burden [Time frame: 6 months post-baseline]
- Anxiety and depression [Time frame: 6 months post-baseline]
- Quality of life (caregiver) [Time frame: 6 months post-baseline]
- Coping strategies [Time frame: 6 months post-baseline]
- Neuropsychiatric symptoms [Time frame: 6 months post-baseline]
- Use of health and social care resources [Time frame: 6 months post-baseline]
