The trial included 15 municipalities in the intervention group. Family caregivers in the intervention group received one or two of the tailored interventions based on their level of burden and specific needs, as assessed by the local primary care dementia coordinator in the municipality. The interventions included: 1) a support group focused on addressing caregiver burden, providing both professional and peer support; 2) a group course consisting of six sessions aimed at helping caregivers cope with everyday challenges; and 3) a group course over five sessions that offered information on dementia, transitioning to a nursing home, person-centered care, and effective communication strategies.

The trial included 15 municipalities in the treatment-as-usual group. Family caregivers in the treatment-as-usual group had access to local health and social services in their municipality, including support and information from primary care dementia coordinators, support groups, hotlines provided by patient associations, and respite care for the person with dementia in a home or daycare setting.

This intervention aimed to promote coping and reduce caregiver burden through professional and peer support. It was delivered over a varied number of sessions, as this depended on the number of recruited participants in the municipalities. To support these sessions, booklets and fact sheets for family caregivers could be incorporated. These materials would cover various topics, including the psychological challenges and reactions faced by family caregivers, guidance on effective communication with people with dementia, and a guide to practical and legal issues. Further, there would be fact sheets addressing specific symptoms, such as memory loss, communication difficulties, depression, apathy, behavioral changes, and reduced awareness of symptoms. The use of these booklets and fact sheets in the intervention would be determined by the municipalities, allowing for adaptation to fit local contexts. Dementia coordinators within the community setting would implement this intervention.

Used to measure the emotional and psychological burden experienced by caregivers of patients with dementia.

Used to measure a person's self-assessed general health on a given day. It's a vertical line scale from 0 (worst imaginable health) to 100 (best imaginable health), where respondents mark their current health state.

Used to measure quality of life in five dimensions, on a 5-point likert scale. Completing it generates a one-digit number for each dimension, which can be converted into a utility score. The closer the utility value is to 1, the better the health state. The EQ-5D-5L utility ranges from -0.757 to 1.
