The purpose of this study is to pilot the home Environmental Skill-Building Program (ESP) and an educational control intervention with persons with dementia and their caregivers (n=40) in preparation for a larger double-blind randomized controlled trial. Caregivers of persons with dementia often deal with difficult behaviors. The ESP is an occupational therapy intervention that helps caregivers adapt to their environment and build care-giving skills. The areas addressed include changes to the home set-up, adaptive equipment, instruction in strategies of problem-solving, energy conservation, safe task performance, and fall recovery techniques. A trial is needed with methodological rigor and to determine if the intervention is feasible in the Canadian health care system. Results will contribute to understanding how caregivers and people with dementia can be supported in their home environments.

Arms Assigned Interventions
Active Comparator: Education Control Behavioral: Active control
Caregiver participants are provided with information about caregiver stress and discuss it individually with an interventionist who visits the home. The control intervention involves 5 visits over 6 months.
Experimental: Environmental Skill Building Behavioral: Environmental Skill Building Program
The ESP intervention addresses home modifications and training in their use, instruction in strategies of problem-solving, energy conservation, safe task performance, fall recovery techniques, and balance and muscle strength training. Intervention is individualized for target areas identified in the initial client assessment and caregiver interview. The intervention involves using a problem solving approach and client-centred focus and the intervention assessment tools are individualized measures which determine the goals identified by the caregiver. It involves 5 visits over 6 months.
