Environmental Design for Behavioral Regulation in People With Dementia

Elizabeth K Rhodus30 enrolled

Overview

Individuals with dementia present with changes in behaviors throughout the continuum of cognitive decline. Environmental features may be influential in behavioral regulation. The purpose of this study is to assess the feasibility of environmental design protocols in older adults with dementia and their caregivers. Thirty subjects with moderate to severe Alzheimer's disease as primary dementia type, and their caregivers, will be randomly assigned to one of three arms: standard care; standard environmental design protocol; or personalized environmental design protocol.

Interventions

Standard Environmental DesignBEHAVIORAL

Participants' caregivers will receive set script of physical environmental modifications (i.e., declutter living space, reduce background noise, increase natural light), and social environment training script will include caregiving techniques: training for calming demeanor (emotional contagion), needs-driven care to decrease behavioral disruption, and accepting and accommodating approach to behavioral disruption. A pre-selected sensory stimulation kit will be provided to each participants' caregiver for administration throughout the day.

Individual Environmental DesignBEHAVIORAL

Participants' caregivers will receive set script of physical environmental modifications and social environment training script in a standard protocol. Following initial assessments, individualized sensory stimulation kits will be developed using subjects' preferred sensory stimuli (as determined by the Adult Sensory Profile assessment and informant report) and will be provided via caregiver administration throughout the day to promote maintained behavioral regulation.

Outcomes

Primary Outcomes

Success Rate of Adherence

Percentage of participants who had 75% adherence to the protocol based on visits and journals.

Time frame: 6 weeks

Secondary Outcomes

Change in Occupational Performance

Occupational performance will be measured using the Canadian Occupational Performance Measure (COPM) at baseline, post-intervention and the 4-week follow up. Scores range from 0-10; higher scores indicate (increased) occupational performance.

Time frame: 10 weeks (at baseline, 6 weeks and the 4 week follow up)

Change in Behavior

Behavior will be measured using the Neuropsychiatric Inventory (NPI-Q) at baseline, post-intervention and the 4-week follow up. Scores range from 1-36; higher scores indicate higher behavior severity.

Time frame: 10 weeks (at baseline, 6 weeks and the 4 week follow up)
