Efficacy of a psychoeducative intervention program to prevent or reduce the burden associated with caring for dementia patients: a two arm single blind, multicentre, randomised controlled trial
1. The caregivers allocated to the psychoeducative intervention program will present less burden at endpoint (4 months) than the caregivers allocated to the control condition.
2. The caregivers allocated to the psychoeducative intervention program will present better mental health at endpoint (4 months) than the caregivers allocated to the control condition.
3. The caregivers allocated to the psychoeducative intervention program will present better quality of life at endpoint (4 months) than the caregivers allocated to the control condition.

Burden associated to dementia caregiving
Control group: Caregivers allocated to this group received the usual support from the day center or memory clinic where the patients had a multifaceted /multiprofessional care which aimed at reducing the rate of cognitive decline (cognitive stimulation groups) and improve or maintain as long as possible daily abilities (occupational therapy). The caregiver received periodical interviews and information about the situation and clinical course of the patient.
Intervention group: Caregivers allocated to this group were exposed to the same usual care the control group received plus a psychoeducative intervention program. This intervention was administered in 7 group sessions of 90 minutes each and the sessions were administered 2 weeks apart. The caregiver received standardised information about the clinical course of dementia and training on different cognitive and behavioural skills to increase her care abilities, communicative skills and relaxation.
Primary outcome measure
Change since baseline to endpoint in the caregiver burden as assessed by the Zarit Burden Interview
Secondary outcome measures
1. Change since baseline to endpoint in the caregiver mental health as assessed by the General Health Questionnaire, 28 items
2. Change since baseline to endpoint in the caregiver quality of life as assessed by the SF-12

Participant inclusion criteria
1. Males or females with age more than or equal to 18 years, giving care to a familiar person with a diagnosis of dementia according to Diagnostic and Statistical Manual of Mental Disorders, 4th Edition (DSM IV)-TR criteria
2. The caregiver was not profesionally paid for caregiving
3. The familiar diagnosed of dementia was receiving appropriate care as outpatient in a day center or memory clinic
4. The caregiver spend a minimum of 4 hours/day to care for the patient with dementia
5. The patient cared for had at least two instrumental activities impaired (a score of 0 in the Lawton & Brody scale) or one activity of daily life impaired (Katz index codes A or D)
6. Signed informed consent to participate in the trial
Target number of participants
An anticipated number of 200 caregivers were estimated to attain 85% power. The trial recruited 238 caregivers (115 randomised to the intervention arm, 123 randomised to the control arm).
Participant exclusion criteria
1. Caregivers without time to attend the psychoeducative intervention training
2. Caregivers receiving currently or recently (last year), any standardised psychoeducative intervention similar to the one administered in the trial
