Study information

Primary study design	Interventional
Study design	Randomised single-blind placebo-controlled cross-over study
Secondary study design	Randomised controlled trial
Scientific title	10/66 Dementia Research Group randomised controlled trial: helping carers to care - Mexico
Study acronym	10/66 Dementia Caregiver Intervention
Study objectives	The primary hypothesis is that an intervention focusing upon education and training of caregivers (10/66 intervention) will be associated with a reduction in caregiver psychological strain (the 20-item Self-Reporting Questionnaire [SRQ-20] score). We further hypothesise that the intervention will be associated with an improvement in the quality of life of both caregivers and people with dementia, and in the distress experienced by caregivers arising from behavioural and psychological symptoms in the person with dementia.
Ethics approval(s)	The study has been approved by: 1. The Institute of Psychiatry ethical committee, King's College London in April 2003 (ref: 076/03) 2. The Ethical committee of the Mental Health Research Centre of the Russian Academy of Medical Sciences in October 2003
Health condition(s) or problem(s) studied	Dementia syndrome
Intervention	60 caregivers of people with dementia in each centre were randomised to receive the intervention immediately (n = 30) or six months later (n = 30). The 10/66 intervention targets the main carer, but includes members of the immediate and extended family. The aim is to provide basic education about dementia and specific training on managing problem behaviours. The three simple, manualised modules are delivered over five, weekly, half hour sessions. 1. Module one: assessment (one session): 1.1. Cognitive/functional impairment 1.2. Carer's knowledge and understanding of dementia 1.3. Care arrangements: 1.3.1. Who are the family members? 1.3.2. Who lives with the person with dementia? 1.3.3. How do they assist the main carer? 1.3.4. Which behavioural problems present most difficulties? 1.3.5. How burdened do they feel? 2. Module two: basic education (two sessions): 2.1. General introduction to the illness 2.2. What to expect in the future 2.3. What causes/does not cause dementia? 2.4. Locally available care and treatment 3. Module three: training on problem behaviours (two sessions): up to eight problem behaviours identified in the assessment are addressed: 3.1. Personal hygiene 3.2. Dressing incontinence 3.3. Repeated questioning 3.4. Clinging 3.5. Aggression 3.6. Wandering 3.7. Apathy
